Mecalux Shop:<br />
a new look, new<br />
clickable content<br />
Keeping with its commitment to innovation<br />
and new technologies, Mecalux has completely<br />
updated its e-commerce portal for<br />
Spain, offering a new design, new content<br />
and a better user experience.<br />
The new Mecalux Shop specialises in the direct<br />
sale of metal shelving and related products<br />
to warehouses, workshops, offices,<br />
archives, change rooms, etc., building on<br />
the extensive knowledge and experience of<br />
Mecalux within the sector.<br />
Among the newly integrated<br />
enhancements<br />
are the following:<br />
• New categories and<br />
advanced search filters which allow<br />
you to easily find any product.<br />
• More information on each product:<br />
description of main product features,<br />
with more detailed technical information<br />
and more pictures.<br />
• Making a purchase is streamlined and<br />
speedy with a user friendly design.<br />
• Optimised design for smartphones and<br />
tablets.<br />
• More advantages for registered users:<br />
custom offers, easy personal data admin,<br />
order tracking, purchase history access,<br />
etc.<br />
Another of the key points of Mecalux Shop<br />
is its Customer Service, with professionals<br />
who know the product and its applica-<br />
tions and that, if necessary, can help the<br />
user to choose between different storage<br />
solutions.<br />
With this rejuvenation and the inclusion of<br />
better features and navigability, Mecalux<br />
has updated its online sales gateway<br />
witn the steady flow of technological<br />
breakthroughs in the field of e-commerce<br />
and in the shifts in user enthusiasm. The<br />
end user will benefit from the esase of use.<br />
Safe and sound: Mecalux introduces<br />
an innovative safety locking mechanism<br />
Safety in the warehouse is the foundation<br />
on which to develop an installation’s day-today<br />
work operations in an efficient and riskfree<br />
way. Therefore, Mecalux invests a significant<br />
part of its R&D resources to improve<br />
the security devices of all its products.<br />
The latest innovation in this respect is the<br />
incorporation of a new junction system<br />
between uprights and beams in Mecalux<br />
pallet racks. This involves a connector with<br />
a locking system, developed to provide<br />
greater safety on the whole.<br />
Its most outstanding contribution is the integration<br />
of a safety locking mechanism in<br />
the actual connector, which results in two<br />
key advantages: on the one hand, it is impossible<br />
for the safety device not to work<br />
or to lose it accidentally; while on the other<br />
hand, once it is assembled it is not possible<br />
to remove it without the disassembly of the<br />
entire beam. This prevents accidental or<br />
deliberate manipulation of the connector –<br />
with a blow by a forklift, for example – thus<br />
avoiding the beam displacement and its<br />
possible consequences, such as the collapse<br />
of the load.<br />
After successfully introducing this new<br />
locking system into installations set up in<br />
the United States, where Mecalux is a leader<br />
in the pallet racking market, it is now<br />
integrating it into all their projects within<br />
Europe.<br />
They are the only manufacturer on the<br />
European continent to develop and incorporate<br />
this breakthrough device into their<br />
storage solutions.<br />

Maxi-innovation for Mecalux’s<br />
semi-automated compact storage<br />
As one of the leading companies in storage<br />
solutions for more than 50 years, Mecalux<br />
invests significant resources in the development<br />
of new products and the continuous<br />
improvement of those which are already<br />
part of their catalogue. It always aims to incorporate<br />
the latest in technological innovations<br />
to deliver better profitability.<br />
So, one of the solutions that has experienced<br />
the greatest amount of development<br />
is the semi-automated Pallet Shuttle. This<br />
compact system uses an electric shuttle<br />
instead of forklifts to handle pallets inside<br />
the storage channels (that can reach 40 m<br />
in depth), considerably reducing manoeuvring<br />
times and helping to streamline storage<br />
processes for all kinds of companies.<br />
Among the new add-on innovations what<br />
stands out is the adoption of Wi-Fi techno-<br />
logy, which multiplies<br />
the system<br />
benefits: the forklift<br />
operator communicates<br />
the storage and<br />
removal orders to the shuttle<br />
using a control tablet with Wi-Fi<br />
connection, with an intuitive, user<br />
friendly interface.<br />
Different key features:<br />
• Input and removal of pallets: continuous<br />
or partial.<br />
• Inventory functionality.<br />
• High speed: 90 m/min without load and<br />
lifting time of 2 s.<br />
• Lithium batteries that provide up to<br />
10 h of autonomous use, with a quick<br />
connect battery compartment that eliminates<br />
the need for cables.<br />
• Pallet type selector (the shuttle supports<br />
various sizes).<br />
• LIFO/FIFO setup to select the load management<br />
strategy.<br />
• Position camera that facilitates the operator<br />
in centralising the pallet on the rails<br />
(optional).<br />
• Security scanner: controls access to<br />
the rails while the shuttle is operating<br />
(optional).<br />
• Additional lock system that increases<br />
the clamping of the electric shuttle to the<br />
forklift blades.<br />
• Compatibility with Mecalux Easy WMS<br />
software, or other generic WMS used by<br />
the customer.<br />
• The lifting platform can receive pallets<br />
with buckling of up to 25 mm.<br />
• Tiltmeter: detects the incorrect position<br />
of the shuttle within the channel<br />
• Rescue: recovers the damaged shuttle<br />
from within the channel<br />
The result is a new generation of Pallet<br />
Shuttle, which capitalises new technologies<br />
to enhance the warehouse performance<br />
and its profitability. It is an ideal solution<br />
for companies with a large volume of pallets<br />
per SKU and high loading and unloading<br />
activity.<br />

Logistics chain<br />
innovation in Argentina<br />
and Peru: clad-rack<br />
warehouses with Pallet<br />
Shuttle to be built<br />
In recent months, the markets of Argentina<br />
and Peru have opted for the compact<br />
storage system Pallet Shuttle by Mecalux.<br />
This solution incorporates numerous innovations<br />
to streamline the processes of the<br />
entry and exit of goods in the warehouse. It<br />
also provides great storage capacity, thanks<br />
to an electric shuttle that loads and unloads<br />
pallets in the interior of the racks, moving<br />
autonomously along rails.<br />
Among the projects recently carried out in<br />
these countries, two constructions, in particular,<br />
stand out that have combined the benefits<br />
of clad-rack warehouses with those<br />
containing Pallet Shuttle racks.<br />
In Argentina, Granja Tres Arroyos, one of<br />
the major producers and exporters of frozen<br />
chicken, has chosen this solution when<br />
building their new frozen cold-storage. The<br />
combination of a clad-rack warehouse with<br />
the Pallet Shuttle system is particularly recommended<br />
in cold-storage, although, the<br />
building is not of great height. In addition<br />
to lowering manoeuvring times, it offers a<br />
high storage capacity that reduces the volumetric<br />
area to be kept cool, resulting in<br />
energy cost savings.<br />
On the other hand, the Mecalux Peru team<br />
has completed the construction of another<br />
clad-rack warehouse with Pallet Shuttle for<br />
Medifarma, one of the top 5 pharmaceutical<br />
laboratories in Peru. In this project, given<br />
the diversity of the products marketed,<br />
the versatility of the system proved essential,<br />
while also increasing the number of cycles<br />
per hour compared to a conventional<br />
system.<br />
In both cases, it is worth noting that<br />
although these clad-rack warehouses are<br />
not very tall, they have also been the most<br />
profitable option for both companies. This<br />
is because the storage channels were constructed<br />
to the depth which was strictly ne-<br />

cessary, calculated according to their required<br />
functionality.<br />
The goal is to put new technologies and<br />
approaches within reach all kinds of companies,<br />
to multiply the productivity and profitability<br />
of storage installations, achieving<br />
maximum performance within the logistics<br />
chain.<br />
Mecalux, in their effort to provide up close<br />
and personal service to its customers, are<br />
present in Argentina with two sales offices<br />
in Buenos Aires and a 21,000 m 2 production<br />
centre, while there is also a delegation in<br />
Lima, Peru. Overall, the strength of the customer<br />
support is second to none.<br />

Çaykur’s, the biggest producer of<br />
Turkish tea, new clad-rack warehouse<br />
in Iyidere (Turkey) will be more than<br />
40 m high and almost 160 m long.<br />
Mecalux will provide a large, single aisle,<br />
automated warehouse served by three<br />
single-column stacker cranes and aided<br />
by Pallet Shuttle that are responsible for<br />
transporting 800 x 1200 x 2600 mm sized<br />
pallets with a maximum weight of 600 kg<br />
each.<br />
In order to optimize accessibility to locations,<br />
Mecalux has developed a control<br />
system and safe passageways that allow<br />
the stacker cranes to enter the annex<br />
zones. This is all controlled by the warehouse<br />
management system Easy WMS and<br />
the Galileo control software.<br />
In addition, input of goods will be done<br />
at the side the warehouse via three raised<br />
overpasses that connect the warehouse<br />
with the docking area. The elevated overpasses<br />
allow for workspace savings so<br />
that the ground floor remains completely<br />
available.<br />
Çaykur, which opened its first tea factory<br />
in 1947, produces 133,000 tons of tea annually<br />
in 46 different factories, making it<br />
the largest tea producer in Turkey and one<br />
of the most important worldwide. This<br />
massive solution could only be properly set<br />
up using Mecalux’s extensive know-how.<br />
All in the family: Mecalux expands<br />
the Familia Group warehouse in Colombia<br />
Familia Group, a company specialising in<br />
personal care and hygiene products, will<br />
expand its current clad-rack warehouse<br />
to reach a capacity of more than 16,000<br />
pallets.<br />
In 2011, Mecalux erected Family Group one<br />
of the first automated warehouses within Colombia.<br />
The installation, with a capacity for<br />
7,416 pallets and 31.2 m high, is managed by<br />
three stacker cranes.<br />
A few years later, the company has again chosen<br />
Mecalux to execute the Cájica warehouse<br />
expansion. The objective: to reach 34.4 m in<br />
height, increase capacity to include another<br />
9,480 pallets, and install an additional three<br />
stacker cranes. Moreover, recirculation is set<br />
up that allows both the management of inputs<br />
from outside sources and internal production,<br />
and also direct dispatch from the warehouse.<br />
The warehouse management system, Easy<br />
WMS software, implemented by Mecalux will<br />
also be supplied.<br />
With this expansion, the Family Group warehouse<br />
will achieve greater inputs and outputs,<br />
bringing it to the forefront of logistics within<br />
the t<strong>issue</strong> and the personal hygiene sector.<br />

Throughput conveyed and supersized: Quality Pascual and<br />
Mecalux collaborate on new conveyor system in Barcelona<br />
This renowned Spanish food and beverage<br />
company has entrusted Mecalux<br />
in the semi-automation of transport<br />
and delivery processes of Leche<br />
Pascual, one of its leading brands, in<br />
its packaging centre located in Gurb<br />
(Barcelona).<br />
After a thorough study, the technical team<br />
at Mecalux opted for the installation of two<br />
automatic conveyor circuits, one on each<br />
floor of the facility, and a lift which connects<br />
the two levels. Therefore, they get the streamlining<br />
of product throughput and the best<br />
use of available space on the warehouse’s<br />
first floor.<br />
The ground floor conveyor circuits will move<br />
pallets from the end of the production area<br />
to three possible destinations: the drive-in<br />
racks situated on the same floor, the dispatch<br />
area, or the storage-ready area on the<br />
first floor.<br />
On the other hand, the conveyor circuit designed<br />
for this upper floor will be reversible,<br />
so that it can be used for both inputs and<br />
outputs of pallets. The maximisation of this<br />
space will make it possible for the Catalan<br />
Pascual plant to dispense with external warehouses,<br />
with subsequent cost and time savings<br />
in the transport of goods between distant<br />
warehouses.<br />
In addition to the lift which connects the two<br />
levels of the warehouse, they complement<br />
the equipment with a pallet stacker and a pallet<br />
unstacker.<br />
All movements of the equipment will be<br />
monitored by the Mecalux Galileo control<br />
software, which is in communication<br />
with the warehouse management software<br />
currently used by the company in this<br />
installation.<br />
To sum up, the project that Mecalux will<br />
set up in the upcoming months in the Gurb<br />
packaging centre will provide Qualidad<br />
Pascual with greater agility and accuracy in<br />
product throughput and dispatches. This is<br />
all part of the group’s commitment to offering<br />
excellent quality service, and the continuous<br />
improvement of both its products<br />
and processes.<br />

Kronopol, one of the world’s leading producers<br />
in wooden material manufacturing,<br />
has commissioned Mecalux to construct<br />
its new automated warehouse for pallets,<br />
where the floor panels fabricated by the<br />
company will be deposited.<br />
The warehouse,<br />
composed of four aisles<br />
with double depth racks,<br />
measures 30.3 m high,<br />
32.9 m wide and 89.3 m<br />
long. In each aisle a stacker<br />
crane will circulate<br />
that is able to move 840 x<br />
1,410 x 1,200 mm pallets,<br />
with a maximum weight<br />
of 1,075 kg each.<br />
This installation, which<br />
is scheduled for completion<br />
in the third quarter<br />
of 2016, was the Kronopol organisation’s<br />
most substantial investment in 2015. Its<br />
construction, apart from increasing storage<br />
capacity by maximising available space, will<br />
give the company a series of advantages.<br />
Among these are complete automation,<br />
an increase in the loading and unloading<br />
speeds of vehicles, and the preclusion of<br />
damaged goods caused by forklift usage. In<br />
addition, the warehouse is also distinguished<br />
by being environmentally friendly because<br />
the solutions used will work via electricity,<br />
which will eliminate the emission of<br />
gases.<br />
The Polish company Kronopol, present in<br />
more than 50 countries, has been part of<br />
the Swiss Krono Group holding company<br />
since 1994. Throughout this process, the<br />
firm has become a worldwide leader in<br />
their sector, thanks to the quality and variety<br />
of their timber products earmarked for<br />
the manufacture of interior finishings and<br />
furniture.<br />

Design and efficiency go<br />
hand in hand: a new automated<br />
clad-rack warehouse designed<br />
by Mecalux for STUA<br />
Founded in 1983 by Jesus Gasca, STUA<br />
in one of the most internationally recognized<br />
Spanish contemporary furniture<br />
design companies. Recently, its operations<br />
moved to a new facility in Astigarraga<br />
(Guipúzcoa) in order to boost continuous<br />
growth.<br />
After assessing various options for the implementation<br />
of a storage system that best resolved<br />
their needs, STUA finally chose the<br />
project submitted by Mecalux, due to the<br />
confidence that being made in Spain and<br />
their extensive experience conveys.<br />
STUA’s objectives are to gain perfect control<br />
of both their products and deliveries to<br />
any part of the world, in addition to maximise<br />
storage capacity. To fulfil these requirements,<br />
Mecalux has planned out a solution<br />
consisting of an automated clad-rack warehouse<br />
annex to the production building that<br />
stands out for its slenderness, since it has had<br />
to adapt to some unusual measurements:<br />
80 m long, 25 m high and only 9 m wide.<br />
The automatic warehouse is made up of<br />
an aisle where a single-mast stacker crane<br />
circulates, which serves the double depth<br />
racks located on both sides. The racking has<br />
10 levels of different heights in order to locate<br />
various sized load units – some larger<br />
than usual – given the characteristics of the<br />
product. The inputs and outputs of the automated<br />
warehouse have been dealt with a<br />
circuit of conveyors.<br />
Last but not least, to manage all warehouse<br />
processes, Mecalux will implement its Easy<br />
WMS warehouse management software,<br />
which will allow the full control STUA stock<br />
and real-time inventory, while also optimising<br />
and coordinating product throughput,<br />
from its entry into the warehouse to its dispatch<br />
to the end customer.<br />
The new automated clad-rack warehouse will<br />
provide STUA with better efficiency and profitability<br />
in their logistics operations. This will,<br />
in turn, give them a competitive advantage in<br />
their job of innovating and promoting Spanish<br />
design, which was recognized in 2008 with<br />
the National Prize for Innovation and Design.<br />

Who is Hayat Kimya?<br />
Founded in 1937, Hayat Kimya is the leading<br />
chemical company in the Turkish, Asian<br />
and Middle Eastern market for cleaning<br />
and hygiene products.<br />
The company has twelve<br />
brands distributed<br />
in three sectors:<br />
household care, hygiene<br />
products and t<strong>issue</strong>s<br />
At present, Hayat Kimya is the seventh largest<br />
manufacturer in Europe in its sector,<br />
having more than 5,200 employees and<br />
reaching all its consumers through an<br />
export network which covers 101 countries.<br />
The needs of Hayat Kimya<br />
The huge growth experienced by Hayat<br />
had obliged them to distribute goods between<br />
several warehouses located near different<br />
production centres, which involved<br />
high logistical costs that could increase<br />
over the years.<br />
Faced with this situation and seeking to reduce<br />
production costs, Hayat Kimya decided<br />
to build a single warehouse with a<br />
minimum storage capacity of 150,000 pallets<br />
and in which to undertake picking<br />
functions.<br />
In addition, and in order to save on transport<br />
costs, they thought of putting it in<br />
a space available in their largest facility,<br />
equal distance from three of their most important<br />
plants and near a fourth high production<br />
site.<br />

Taking into account the above premises<br />
and the data provided by Hayat Kimya,<br />
Mecalux worked from the outset in the design<br />
and construction of a warehouse with<br />
the following features:<br />
- Automated clad-rack warehouse<br />
with a capacity for 161,000 pallets.<br />
- Four raised overpasses above the lanes<br />
inside the installation that connect<br />
the factories and the main conveyor circuit.<br />
- A ground floor dedicated almost exclusively<br />
to dispatches, with the exception<br />
of two multipurpose docks and a dock<br />
fitted with an automated unloading system<br />
intended for the receipt of merchandise<br />
from other factories.<br />
- First floor used exclusively for offices<br />
and other services.<br />
- Second floor reserved entirely for picking.<br />
- On the third floor is where all inputs<br />
take place in the warehouse from the<br />
factories that are located in the complex,<br />
as well as the outputs intended for picking<br />
areas.<br />
- Wide manoeuvring area and loading/<br />

The warehouse<br />
The size of the warehouse is 120 m long x<br />
105 m wide and 46 m tall, with a total capacity<br />
that exceeds 161,000 pallets that<br />
are 800 x 1200 mm in size and weigh a<br />
maximum 700 kg each.<br />
The construction system is self-supporting,<br />
that is to say the racks, in addition<br />
to storing goods, have additional structures<br />
on which sheet clad panels are<br />
attached to that make up the building.<br />
This forms a complete unit that is the<br />
warehouse.<br />
The racks must support their own weight,<br />
the pallets stored, the wind pressure, handling<br />
equipment, the seismic activity on<br />
the basis of the coefficient indicated at the<br />
construction site and the weight of snow<br />
that conforms to the regulations.<br />
The Hayat Kimya warehouse consists of<br />
15 aisles with double-depth racks placed<br />
on both sides and is 24 load levels high. In<br />
each aisle a 45 m high stacker crane was<br />
set up that is responsible for the movements<br />
within the warehouse, from the reception<br />
area to product locations.<br />
Each stacker crane is equipped with a<br />
double cradle that allows two pallets<br />
to be moved at a time and with singlemast<br />
construction, something unusual<br />
for a warehouse of this height. The maintenance<br />
of the stacker cranes is carried out<br />
on the side that coincides with the conveyor<br />
circuit.<br />
It is interesting to point out that in each<br />
of the 24 load levels that integrate rack<br />
bays, three pallets in the first position and<br />
three other pallets in the second are stored.<br />
This is very difficult to achieve in a tall<br />
warehouse which is located, as explained<br />
below, in an area with such a high rate of<br />
seismic activity.<br />
In this image the loading<br />
docks and the offices<br />
located on the bottom<br />
floor of the warehouse<br />
can be seen.<br />

The warehouse itself is an enclosed box<br />
in which all passages between the inside<br />
and the outside connection floor are done<br />
through airlocks that help maintain the<br />
atmosphere required by the fire protection<br />
system.<br />
This system (inerting) works by reducing<br />
the oxygen in the interior’s air, to an<br />
atmospheric level of 14%, at which point<br />
combustion is no longer possible. A piece<br />
of equipment controls the oxygen levels<br />
in the air and adds nitrogen until reaching<br />
the percentage that has been previously<br />
programmed.<br />
The final solution<br />
was the construction<br />
of a huge 12.500 m 2<br />
logistics centre, with<br />
a 46 m tall, clad-rack<br />
warehouse, readied<br />
to house up to<br />
161,000 pallets<br />

The city of Izmit is located at the beginning<br />
of the Northern Anatolian fault line, which<br />
runs along the upper zone of the peninsula<br />
and which makes up the greater part of<br />

To build a warehouse of these dimensions<br />
in a place with such a high rate of earthquakes,<br />
with a height of more than 45 m<br />
and with stacker cranes prepared to move<br />
two pallets at a time and operate in doubledepth<br />
racks, was a challenge never before<br />
surpassed by Mecalux. Furthermore, the<br />
warehouse was built in an area exposed<br />

Case Study I Hayat Kimya<br />
to the wind and where snowfall, although<br />
not frequent, can be abundant when it<br />
does occur.<br />
With all these constraints, only one company<br />
with the experience and quality of<br />
Mecalux was able to build a warehouse on<br />
this scale.<br />
The main difficulty Mecalux faced was<br />
the existence of a major earthquake zone right<br />
where Hayat Kimya wanted to build its<br />
upcoming central warehouse<br />
By its particularities, this logistics centre<br />
could not be built with the traditional<br />
cold-formed profiles. Nor was it possible<br />
to do so with a structure of standard hot<br />
rolled profiles, due to the accuracy of assembly<br />
that this installation required was<br />
extremely high.<br />
The solution provided by Mecalux’s technical<br />
team was to combine the two con-<br />
structive options. The first to conform all<br />
racks, and the second to complete the<br />
construction of a vertical reticulate structure<br />
coupled to the racks.<br />
The objective was to absorb all the horizontal<br />
dynamic forces, mainly those of a<br />
longitudinal direction, which is the least<br />
rigid part of the racks.<br />
The weight of this additional structure was<br />
more than 1,900 t (for the whole structure<br />
10,000 t was used).<br />
Both the dimensions and mode of operation,<br />
as the building’s location, represented<br />
a challenge for the Mecalux’s Structural<br />
Engineering department that had to deal<br />
with some extreme determinants.<br />

Upper floor: inputs<br />
All warehouse inputs from the factories<br />
that are located on-premises take place<br />
on the third floor of Hayat Kimya’s logistics<br />
centre. The accumulative automatic roller<br />
conveyors have been set up in the four<br />
overpasses connecting the warehouse to<br />
the factories.<br />
All the factories have a conveyor circuit<br />
that is tasked with the input of the pallets<br />
into the system after checking both<br />
its size and its weight. Only then will they<br />
ensure that the pallets that arrive to the<br />
warehouse do so in good condition.<br />
In each overpass two lifts were placed, one<br />
in each factory’s entry points and an other<br />
at the end of each overpass, allowing<br />
goods to be lifted to transport height and<br />
subsequently to the third floor. At the same<br />
time, this floor has a triple electrified monorail<br />
circuit running both the external and<br />
internal movements of the warehouse.<br />
On the third floor, alongside inputs, outputs<br />
of goods that are lowered to the designated<br />
picking floor are also done via the<br />
elevators.<br />
Every day an average<br />
of 6,500 pallets come<br />
into the warehouse,<br />
peaking at 400 pallets<br />
per hour<br />

dividing it into two areas:<br />
Zone A: 118 live channels, each three pallets<br />

goods from the lifts.<br />
This area is intended for A type products<br />
(high demand).<br />

Zone B: 174 pallet racking bays with 2 or<br />
4 levels for pallets, including the ground<br />
floor, grouped into four double and two<br />
single rack alignments.<br />
It has a total capacity of 500 pallets for<br />
picking placed directly on the floor and<br />
1,050 reserve pallets on upper levels. This<br />
second area is allocated for the picking of<br />
B type products (medium demand).<br />
In addition, the same racks were set up for<br />
levels of live box picking to give access to<br />
C type products (low demand).<br />
The feeding of the pallet racks is performed<br />
using front loading reach trucks that<br />
take the pallets from the warehouse in a<br />
specific exit, where one of the lifts has previously<br />
deposited the pallets destined for<br />
this zone.<br />
Picking is done manually by the operators,<br />
aided by order fulfilment machines<br />
and a computer terminal that works via<br />
radio frequency.<br />
When the orders are<br />
completed, they are taken<br />
to the baling area and,<br />
via two lifts, are sent to<br />
the ground floor to be<br />
dispatched<br />

Lower floor: dispatches<br />
All outputs designated for the dispatch<br />
area are carried out on the ground floor<br />
by electrified monorails. These automated<br />
transport units take the pallets from the<br />
conveyor output inside the warehouse,<br />
and the lifts that descend from the picking<br />
floor, and classify them into preloads.<br />
The preloads are composed of 17 triplechannel<br />
groupings, which have a capacity<br />
to deep-store 11 pallets.<br />
Each triple-channel group has a total capacity<br />
of 33 pallets each that correspond to<br />
an order, route or an out-sourced means of<br />
transport (truck or sea container). This request<br />
is prepared before loading the truck<br />
to avoid waiting time in goods being dispatched<br />
from the warehouse.<br />

Depending on the means of transport<br />
used, and the agreements with company’s<br />
individual customers, the merchandise<br />
is shipped on pallets (usually by truck) or<br />
in single, stacked boxes (sea container).<br />
For loading trucks generally light, front<br />
loading forklifts are used, since they are<br />
very agile and thus the most suitable.<br />
The dispatch area has 17 docks only for<br />

The inputs take place on the ground floor<br />
via three reception docks, one of which is<br />
readied to automatically run unloading.<br />
The automatic<br />
unloads accumulation<br />
device can receive<br />
all the pallets of a full<br />
truckload (trucks are<br />
set up with similar<br />
equipment)<br />
From here, the pallets pass, one by one,<br />
through the checkpoint and continue via<br />
the electrified monorails to the input<br />
stations located inside the warehouse that<br />
is found on this floor.<br />

Electrified monorails and airlocks<br />
All movements from the stations to the<br />
inside of the warehouse, both on the third<br />
floor and on the ground floor, are carried<br />
out by autonomous shuttles hung from<br />
electrified monorail that works at a speed<br />
of 100 meters per minute.<br />
There are more than 900 meters of electrified<br />
monorail and 55 autonomous shuttles<br />
in the entire installation that are able to<br />
move more than 850 pallets per hour<br />
The warehouse should be as airtight as<br />
possible to avoid the entry of air currents<br />
with a higher percentage of oxygen. This<br />
means that all the merchandise that enters<br />
and exits via the electrified monorails<br />
passes through a sealed area with double<br />
doors or airlocks that can never be opened<br />
at the same time.<br />
These spots are often bottlenecks in an<br />
unattended installation – consequently in<br />
this case, which work via electrified monorails<br />
and where there are also very high<br />
flow rates – it was necessary to design several<br />
accesses with triple inner shuttle capacity.<br />
In other words, the shuttles of the<br />
electrified monorails pass three at a time.<br />

designing and marketing medium to highend<br />
shoes for men, women and child.<br />
After almost 25 years, Gioseppo is currently<br />
a well-established brand whose<br />
products are marketed in more than 60<br />
countries worldwide.<br />
Its growth and track record has led<br />
Gioseppo to be included in the prestigious<br />
‘Forum for Renowned Spanish Brand’s’, an<br />
alliance made up of companies and leading<br />
brands from their respective sectors.<br />
Logistical needs<br />
The objectives presented by Gioseppo to<br />
Mecalux were very specific: build a warehouse<br />
to increase its storage capacity to locate<br />
all products coming from production,<br />
and automate the internal transport of<br />
goods with the purpose of managing a<br />
greater number of SKUs in the most efficient<br />
way possible.<br />
With this, the company would take a qualitative<br />
leap forward on a logistical level that<br />
could reduce production costs, while improving<br />
warehouse productivity<br />
Based on these requirements, Mecalux designed<br />
an integrated solution in which automated<br />
storage processes were more profitable<br />
for Gioseppo.<br />

Another premise that Mecalux had to keep<br />
in mind was to pay careful attention to the<br />
public image of the company. It was of utmost<br />
importance to limit the impact constructing<br />
a clad-rack warehouse would<br />
have on the landscape of the Gioseppo<br />
“Love Work Place” logistics centre, an<br />
environmentally friendly space near the<br />
Mediterranean Sea.<br />
Accordingly, the dimensions of the logistics<br />
centre could not exceed a certain height.<br />
So, it was necessary to find a solution that<br />
offered high storage capacity, while at the<br />
same time reducing the installation’s size.<br />

Case Study I Gioseppo<br />
A clad-rack warehouse as a solution<br />
This 18.5 m high, 79 m long and 21.5 m<br />
wide clad-rack warehouse is composed<br />
of three aisles with double-deep racks on<br />
both sides, offering a storage capacity of<br />
5,844 pallets, weighing 500 kg each. To be<br />
clad-rack means that the structure of the<br />
building is formed by the racks themselves,<br />
and that the outer cladding is supported<br />
and attached to them.<br />
For structural calculations of clad-rack<br />
warehouses the following are taken into<br />
account: its own weight; the weight of the<br />
goods stored; the wind pressure both push<br />
and suction depending where it is built; the<br />
weight of the snow as indicated by the regulations;<br />
ramming by stacker cranes; and<br />
finally, the seismicity corresponding to the<br />
territory in which it is located.<br />
Its purpose, as explained above, was twofold:<br />
to optimise height in order to a chieve<br />
the largest possible storage capacity, and<br />
reduce landscape impact to preserve<br />
Gioseppo’s public image.<br />
In each aisle a stacker crane circulates,<br />
hand ling the movements of the pallets<br />
from the conveyors at the end of the aisle<br />
to its designated location.<br />
The use of stacker cranes helps increase<br />
productivity, at the same time decreasing<br />
the resources required to manipulate the<br />
goods.<br />
Gioseppo’s clad-rack<br />
warehouse is distinctive<br />
because they excavated<br />
a 6 meter deep trench<br />
where a large portion<br />
of the warehouse was<br />
installed<br />

Inputs and outputs<br />
The inputs and outputs of palletised goods<br />
are done via a double shuttle that connects<br />
the main circuit of conveyors with<br />
the stor age aisles. The goods input area<br />
has an entry checkpoint, which is responsible<br />
for verifying that the size, weight, and<br />
condition of the pallets comply with the<br />
installation’s specifications.<br />

Picking functions<br />
This same transfer car is tasked with transferring<br />
the pallets from the aisles to the P&D<br />
stations. The picking area is organised star t-<br />
ing with six independent stations where<br />
operators take the boxes they need from<br />
the pallet and deposit them onto the box<br />
conveyor with the order sorter located on<br />
the back.<br />
In addition, and in order to facilitate work,<br />
each picking station has a lift table so that<br />
the pallets are kept at the ideal height for<br />
each operator, improving its ergonomic<br />
position.<br />

Live racks for orders completed and<br />
consumer products<br />
A block of 36 live rack channels has been<br />
installed both for storing orders prepared,<br />
as well as the stacks of idle pallets.<br />
This 8 m high, 9.5 m long and 11 m deep<br />
warehouse has a storage capacity of<br />
324 pallets 800 x 1,200 x 1,900 mm in<br />
size, each with a maximum weight of<br />
400 kg. Each channel receives nine pallets.<br />
The live racks are a compact storage system<br />
that allows maximum use of space and<br />
that are composed of roller channels on a<br />
slight incline. The pallets are inserted into<br />
the highest part of the rack and move via<br />
gravity to the lower end, being available to<br />
the operator. The pallet travel speed is controlled<br />
by roller brakes.<br />
Therefore, this storage system is ideal<br />
for lowering handling times and expedites<br />
picking, increasing the installation’s<br />
productivity.<br />

Easy WMS: the nerve centre<br />
of the installation<br />
In Gioseppo’s new warehouse the warehouse<br />
management system Mecalux Easy<br />
WMS was implemented to manage and<br />
coordinate the different automated operations<br />
that take place within the installation:<br />
the input and output of goods, storage,<br />
picking and dispatches.<br />
This powerful management software has<br />
been customised to Gioseppo’s demands,<br />
being able to: locate pallets in the racks<br />
based on algorithms or parametrisable<br />
rules, manage outputs on the basis of traceability<br />
and FIFO criteria, check the stock,<br />
run standard and custom labelling of containers,<br />
group output orders in different<br />
modalities, etc.<br />
Easy WMS (warehouse management software)<br />
provides a competitive advant age<br />
to Gioseppo, since it involves cost savings,<br />
an improvement in service quality<br />
and consequently, maximising warehouse<br />
profitability.<br />
In addition, Easy WMS is in permanent<br />
communication with the SAP ERP,<br />
Gioseppo’s main management system, exchanging<br />

design feature for Ypê warehouse in São Paulo<br />
Location: Brazil<br />
Ypê, a company dedicated to the<br />
development of cleaning products for<br />
the household and personal hygiene,<br />
has hired Mecalux to install a 29.5 m<br />
high automated clad-rack warehouse<br />
with a 24,168 pallet storage capacity<br />

Analysing the needs<br />
The main production centre of Ypê is located<br />
in Amparo, a town close to the city of<br />
São Paulo. The growing needs of the company<br />
required the construction of a large logistics<br />
centre next to the production plants,<br />
from which they could offer comprehensive<br />
service, and at the same time reduce costs.<br />
Mecalux installed the racks and structures<br />
of the warehouse, the automatic internal<br />
handling equipment, the construction<br />
of a picking area and Mecalux Easy WMS<br />
software deployment, the warehouse<br />
management system which governs and<br />
controls the operations of the logistics<br />
centre.<br />

capacity of Ypê<br />
Solution adopted:<br />
clad-rack warehouse<br />
The most striking part of the project developed<br />
by Mecalux is the installation<br />
of a self-supporting construction warehouse<br />
with a total capacity of 24,168 pallets,<br />
1000 x 1200 mm in size, each with a<br />
weight of 1,300 kg.<br />
Being clad-racked, the racks are a fundamental<br />
part of the structure of the building<br />
and cladding is placed on them. In addition<br />
to its own weight, it must withstand the<br />
pallets stored, the force of the wind on the<br />
basis of the site characteristics, the pressure<br />
of the handling equipment and the<br />
seismic risk that corresponds to the zone in<br />
accordance with the country’s regulations.<br />
of eight storage aisles, with racks on both<br />
sides, of which five are double-depth and<br />
three single-depth.<br />
Each aisle is set up with a twin-mast stacker<br />
crane that automatically performs the<br />
movements between locations and the<br />
main conveyor circuit, placed at the header<br />
of the warehouse.<br />
The traditionally constructed buildings are<br />
adjacent to Ypê’s logistics centre, just besides<br />
the automated warehouse, where<br />
available space has been set aside for future<br />
expansion.<br />

goods, occupying one of the sides of<br />
the warehouse.<br />
A conveyor with accumulation capacity<br />
transports them to the header, where the<br />
main conveyor circuits are placed.<br />
A large percentage of the pallets that leave<br />
the warehouse do so designated for the<br />

As of now, there are five groups of live<br />
channels outfitted and one for pallets<br />
placed on the floor of the warehouse.<br />

The installation<br />
that Ypê has in São Paulo,<br />
with a 24,168 pallet<br />
capacity, is expected to<br />
achieve a total flow of<br />
200 pallets/hour in inputs<br />
and outputs<br />
Each grouping contains 66 channels with<br />
a three pallet capacity. The feeding is performed<br />
via transfer cars that automatically<br />
move from specific positions of the header<br />
to the live channels. The slight tilt with<br />
which channels are mounted allows the<br />
pallet to move by gravity to the closest free<br />
position in work aisles.<br />
Among the five groups, there is a total of<br />
330 channels with a capacity for 990 pallets;<br />
each channel is intended for a single<br />
SKU. Apart from that, there are 138 positions<br />
for pallets placed on the floor, which<br />
are directly supplied by forklifts.<br />
The consolidation of orders, once the pallets<br />
have already passed by the balers, is<br />
carried out in the area allocated to preloads<br />
close to the loading docks.<br />
The logistics centre of Ypê also features live<br />
racks to store consumer products that do<br />
not enter into the automated warehouse.<br />
This area, next to the docks, works as crossdocking,<br />
the live racks acting as a buffer.<br />
Easy WMS: the nerve centre<br />
of the logistics centre<br />
Easy WMS is a powerful warehouse management<br />
system developed by Mecalux<br />
with which you can manage all the warehouse<br />
needs, stepping in from when the<br />
goods are received till the order has been<br />
dispatched.<br />
Among all the functions that Easy WMS is<br />
capable of performing, the most important<br />
are: the receipt and registration of<br />
the pallets that enter into the warehouse,<br />
the management of the locations on the<br />
basis of rules or parametrable algorithms,<br />
control of outputs in accordance with FIFO<br />
criteria and traceability, order preparation,<br />
consolidation, label issuing, documentation<br />
prior to delivery, etc.<br />
All of this with the major advantage of reducing<br />
the errors arising from manual management<br />
to a minimum.<br />
Furthermore, the Mecalux Easy WMS<br />
warehouse management software is continuously<br />
and directly connected to the<br />
ERP of Ypê, from which it receives the background<br />
information and that reports the<br />
outputs executed.<br />

Case Study I Takeda<br />
Takeda, one of the most important<br />
pharmaceutical companies in the<br />
world, has entrusted Mecalux to<br />
build a turnkey warehouse in its<br />
new Lyszkowice production plant,<br />
near the Polish city of Lowicz.<br />
The solution was to construct a<br />
temperature controlled, 32.5 m<br />
high clad-rack warehouse with<br />
a capacity to store more than<br />
6,500 pallets. It is equipped<br />
with a cold storage system and<br />
an ‘oxygen reduction system’<br />
for fire prevention. They were<br />
also supplied with a warehouse<br />
management system, the Mecalux<br />
Easy WMS, which is responsible<br />
for managing all the centre’s<br />
processes.<br />
Who is Takeda?<br />
Takeda Pharmaceutical Company Limited,<br />
with its headquarters in Osaka (Japan), is<br />
a global company specialising in the invest<br />
igation of pharmaceutical products. In<br />
the mid-twentieth century, it experienced<br />
massive growth, making it a world leader<br />
in the pharmaceutical industry and the<br />
larg est of its kind in Japan.<br />
A clad-rack warehouse as a solution<br />
When Takeda moved forward with the expansion<br />
of its production centre, it was very<br />
clear that the warehouse should be automated.<br />
This would allow for perfect control<br />
of stored goods, in addition to being<br />
able to achieve the maximum permissible<br />
height, given that the space available for<br />
warehouse construction was limited.<br />
The solution proposed by Mecalux was the<br />
construction of a 32.5 m high clad-rack<br />
warehouse located next to the manufact<br />
uring facilities and the bay assigned to<br />
delivery preloading. In this type of cons-<br />
The company has a commercial pre sence<br />
in more than 70 countries, most significantly<br />
those in Asia, North America and<br />
Europe and emerging markets such as<br />
Latin America, Russia and China.<br />
truction, the racks themselves make up<br />
the structure of the warehouse.<br />
The installation consists of two aisles, in<br />
which two automatic stacker cranes move<br />
independently, handling the pallets stored<br />
in double-deep racks (two pallets in depth<br />
on each level). Thanks to the optimal space<br />
utilisation, the Takeda warehouse has a<br />
storage capacity of more than 6,500 pallets<br />
in a surface area of only 950 m 2 .<br />
The warehouse was equipped with a<br />
HVAC system (Heating Ventilation Air<br />
Conditioning) which keeps the temperature<br />
between 16 and 24 °C and prevents<br />
the humidity level from exceeding 70%,<br />
which is something that could affect<br />
goods stored.<br />

For structural calculations of clad-rack<br />
warehouses the following are taken into<br />
account: its own weight; the weight of the<br />
goods stored; the wind pressure both push<br />
and suction where it is built; the weight of<br />
the snow as indicated by the regulations;<br />
thrusts by stacker cranes; and finally, the<br />
seismicity corresponding to the territory<br />
where it is located.<br />
This 32.5 meter high clad-rack warehouse has a storage<br />
capacity of 6,584 pallets, 800 x 1200 mm in size,<br />
with a maximum weight of 800 kg<br />
Due to the slenderness of the building<br />
(14.5 m wide and 32.4 m high), a highly reinforced<br />
structure was built. Also, many<br />
large sized anchorages have been placed<br />
with the aim of absorbing maximum wind<br />
pressure.<br />

properly manage all internal operations,<br />
carried out by a single company.<br />
That is why Mecalux was commissioned to<br />
run the turnkey project from beginning to<br />
end.<br />
Stages of warehouse implementation:<br />
- Land preparation via pilings: due to<br />
the low bearing capacity of the soil, and<br />
the large static demands, a deep foundation<br />
was made on pilings.<br />
- Installation of a reinforced concrete<br />
foundation slab: first a reinforced top<br />
and bottom was built with steel rods, and<br />
subsequently the ground was filled with<br />
concrete.<br />
- Finish: the foundation was finished and<br />
hardened with the objective of obtaining<br />
dust free paving.<br />
- Rack assembly: regarding clad-rack<br />
warehouse, the racks themselves make<br />
up the actual structure.<br />
- Assembly of warehouse cladding:<br />
in clad-rack warehouses wall panelling<br />
and ‘sandwich type’ roofs are fastened<br />
directly to the rack structure. In Takeda’s<br />
case, and having used an inerting system,<br />
it was necessary for the outside cladding<br />
to be as watertight as possible.<br />

Cold storage<br />
There are a total of 31 double mobile bases<br />
and four non-moving racks which give<br />
a storage capacity of 4,930 pallets 1,200 x<br />
1,200 mm in size, and have a maximum<br />
weight of 2,100 kg each, which conserves<br />
processed materials at a controlled<br />
temperature.<br />
The racks are arranged in two large blocks<br />
separated by a main gangway. Each block<br />
has a wide work aisle that opens up between<br />
racks. To automatically open it, the<br />
operator must only push a button via the<br />
remote control.<br />
For the purpose of ensuring the security of<br />
its operators and the installation in general,<br />
the Movirack system has the following<br />
devices: external optical safety barriers,<br />
longitudinal photocells placed on both<br />
sides of the bases, proximity sensors, preprogrammed<br />
activation protocols and<br />
emergency stop and reset buttons.<br />
The forklifts that are used in the refrigerated<br />
storage area are the retractable type<br />
that makes it possible to work in an aisle<br />

Conventional pallet racks<br />
The conventional pallet rack warehouse<br />
is intended for bulkier products and items<br />
with greater turnover (A type) placed<br />
upon pallets. Racks have two inferior levels<br />
to conduct direct picking from the pallets,<br />
while reserves are placed on superior<br />
levels.<br />
This storage system is characterised by<br />
its simplicity and capacity to adapt itself<br />
to the needs of the company. In addition,<br />
conventional pallet racks make it possible<br />
to directly access each pallet, storing the<br />
maximum number of unit loads in a safe<br />
and organised way.<br />
The miniload warehouse<br />
A miniload warehouse with four aisles,<br />
and two doubledeep racks (one per side),<br />
was installed, allowing storage of a total<br />
of 15,872 plastic euroboxes, 600 x 400 x<br />
320 mm in size. The height of the racks is<br />
12.3 m and the total admissible weight per<br />
box is 50 kg.<br />
All medium and small sized products are<br />
located in the miniload warehouse, generally<br />
B and C type items. These products<br />
are handled by four stacker cranes, three<br />

Main picking area circuit<br />
Picking stations<br />
The enclosure where the main warehouse<br />
is located is independent of other buildings<br />
and, in particular, from the picking<br />
station, which was installed on the side of<br />
the warehouse.<br />
The picking stations, in the shape of a “U”,<br />
are located terraced perpendicularly to the<br />
main conveyors.<br />
These conveyors are comprised of a double<br />
circuit that allows both the recirculation<br />
of boxes, as well as the connection<br />
to the warehouse and the replenishment<br />
station. Moving boxes to either of the two<br />
main conveyors is direct, thus avoiding unnecessary<br />
movements.<br />
Each station, with capacity for three boxes<br />
on hold plus the one which is being processed,<br />
is run by an operator, who in turn<br />
is able to prepare waves of six orders at the<br />
same time. To that end, there is a computer<br />
connected to the Mecalux Easy WMS<br />
(warehouse management software) and<br />
different support devices for picking. For<br />
example, put to light devices placed on top<br />
of the containers of each order, indicating<br />
to the operator which order each item<br />
corresponds to.<br />
On the pallets/containers of each order,<br />
the item location in the pallet racks has<br />
been previously introduced, that is to say,<br />
this same zone serves as an order consolidation<br />
area. In this way, fast and agile<br />

Mecalux equips Luís Simões’ new<br />
installations in Portugal with Pallet Shuttle<br />
and conventional pallet racking<br />
Location: Portugal<br />
This warehouse, separated into<br />
two distinct areas and built under<br />
the “multi-client” concept, covers<br />
a surface area of 17,500 square<br />
metres and can supply more than<br />
33,000 pallets.<br />
Luís Simões performs all of its<br />
business-related activities from<br />
this installation, including storage<br />
and picking, mass and capillary<br />
distribution.<br />
What is Luís Simões:<br />
what are its needs?<br />
Luís Simões is a comprehensive transport<br />
and logistics services operator that began<br />
operating in 1948 in the portuguese city<br />
of Loures.<br />
The firm has operated in Spain for over<br />
25 years, and is currently the market leader<br />
in trade flows between the two countries,<br />
with a fleet of 2,000 vehicles (owned and<br />
outsourced) and over 1,500 employees.<br />
According to its storage facilities expansion<br />
and modernisation plan, the company<br />
commissioned Mecalux to equip<br />
two large, newly built sites, with almost<br />
10,000 m 2 of surface area each.<br />
Luís Simões needed to speed up the flow<br />
of incoming and outgoing pallets in the<br />
warehouse while, at the same time, increasing<br />
storage capacity. This was needed<br />
to efficiently meet the demands of both<br />
existing and potential customers.<br />

Seven double and one single conventional<br />
pallet racks were installed, along with<br />
two compact racking units with the Pallet<br />
Shuttle system. They feature six load levels<br />
and the capacity to deepstore 15 pallets<br />
per level.<br />
The lower level of the conventional pallet<br />
racking was prepared to perform picking<br />
functions, because a high percentage of<br />
Luís Simões’s orders require it. Moreover,<br />
a spacious area was provided for subsequently<br />
consolidating the orders.<br />
The docks, located on either side, have their<br />
own preloading channels on the ground;<br />
these allow access to the pallets from both<br />
sides, thus optimising truck loading.<br />

This storage system, which was installed in<br />
both warehouses, has two major advantages:<br />
direct access to any pallet, and the<br />
ability to devote the lower level to picking<br />

The machines used are high-lift reach<br />
trucks that can operate in a 3-metre wide<br />

Case Study I Luís Simões<br />
The racks using Pallet Shuttle are operated<br />
as follows:<br />
1. Using the forklift, the operator introduces<br />
the Pallet Shuttle into the corresponding<br />
channel.<br />
2. With the pallet loaded, the Pallet Shuttle<br />
moves horizontally until it reaches the<br />
first free location, where it leaves the<br />
pallet.<br />
3. While the Pallet Shuttle moves and<br />
places the pallet into its location, the<br />
opera tor places another pallet in the original<br />
position in the channel.<br />
Thus, when the shuttle returns to the<br />
beginning of the lane it can successively<br />
repeat the same movement.<br />
When loading in the channel is completed,<br />
the Pallet Shuttle is moved on to the next<br />
one. Extraction is done by reversing these<br />
steps.<br />

Storage of products on pallets<br />
Due to the fact that the majority of orders<br />
delivered by DHL to these stores are full<br />
boxes and they move very few pallets with<br />
a single item type, it was necessary to allocate<br />
the bottom level of the conventional<br />
pallet racks for picking activities. Reserve<br />
palletised goods are stored on higher<br />
levels.<br />
Handling equipment used to place the<br />
pallets on the racks are reach trucks.<br />
However, during order preparation, specific<br />
machines are used that have the<br />
ca pacity to transport up to two pallets at<br />
a time.<br />
80 <strong>Best</strong> <strong>Practices</strong>
Case Study I DHL<br />
Operators maximise streamlining routes<br />
inside the logistics centre thanks to<br />
the WMS (Warehouse Management<br />
Software), which divides the warehouse<br />
so that each operator is responsible for a<br />
single zone. This means that an order can<br />
be prepared by several people at the same<br />
time. Once their part of the order is finished,<br />
each operator will transfer it to one of<br />
the consolidation areas according to the<br />
assigned dock.<br />
Full use of the racks was made to install fire<br />
protection system pipelines and sprinklers.<br />
These coincide with the rack beams or girders<br />
to waste the minimum space possible.<br />

Assembly by phases<br />
Mecalux adapted to the company’s needs,<br />
thus they decided to build the warehouse<br />
in phases. So, DHL could make a tailored,<br />
gradual investment as it ran each project<br />
phase.<br />
Aisle length forced them to build intermediate<br />
passageways wide enough to<br />
give two pieces of handling equipment<br />
the ability to cross each other at the same<br />
point.<br />
Each sector of the warehouse has its own<br />
loading docks in order to avoid large displacements<br />
and significantly reduce operating<br />
costs. The warehouse is also compartmentalised<br />
for security reasons.<br />
The breadth of consolidation areas, and<br />
the laying of pre-loads on the floor just<br />

Advantages for DHL<br />
- Streamlining the space: the DHL warehouse is set up to store more than 90,000 pallets and more<br />
than 30,000 m of hanger profiles.<br />
- Increased productivity: the compartmentalisation of items, the breadth of consolidation areas and<br />
the location of pre-loading zones are some of the factors that help increase the volume and efficiency<br />
of the movement of goods.<br />
- Cost savings: each sector has its own loading dock, thus avoiding large displacements and notably<br />
reducing operation costs.<br />
- Efficient service: thanks to this new logistics center, DHL has met the high level of service demanded<br />
by its customers and is capable of offering fast delivery without errors in the goods sent.<br />

France, hired Mecalux<br />
to install the necessary equipment<br />
in its warehouse in Saint‐Priest,<br />
a town near the city of Lyon.<br />

Case Study I PAVI‐Groupauto<br />
Analysing the needs<br />
The needs of PAVI-Groupauto required<br />
the construction of a warehouse capable<br />
of storing a large number of SKUs of<br />
varying dimensions and characteristics, as<br />
well as being low consumption.<br />
To do this, a storage system was needed<br />
that offered optimal use of the surface<br />
area, as well as being highly flexible and<br />
allowing direct access to any product.<br />
The main objective of the company was<br />
thus met: rapid service for its customers.<br />
Solution adopted: a conveyor circuit<br />
The need to maximise the size of the warehouse<br />
and the fact that most of the orders<br />
consist of very few units and different<br />
SKUs led Mecalux to propose and install<br />
the following solution:<br />
- Construction of a structure capable<br />
of integrating two raised floors on a<br />
2,000 m 2 area, which would allow the<br />
floor space to be tripled.<br />
- Installation, on each of the floors, of<br />
racking with different sizes and types of<br />
distribution in order to suit the different<br />
products.<br />
- Implementation of a continuous and<br />
automatic transport system connecting<br />
all the floors. This means operators can<br />
prepare orders by area, and transport<br />
them to the specific sorting and consolidation<br />
area after completion. The circuit<br />
is also used to send empty boxes from<br />
the lower level to the order preparation<br />
stations.<br />
- Replenishment of the goods directly<br />
from the receiving container to their locations.<br />
On each floor, pallet unloading<br />
docks have been installed on the other<br />
side of safety swing doors.<br />

- Swivel modules have also been located<br />
at strategic points along the transport<br />
circuit for the passage of operators.<br />
- Installation of access stairs between<br />
floors, enabling access and rapid evacuation<br />
during possible emergencies.<br />
All of this is controlled using the Mecalux<br />
Easy WMS warehouse management<br />
system.<br />

Ground floor<br />
The ground floor is dedicated to bulkier<br />
products with direct picking and does not<br />
require the use of conveyors.<br />
Also, the high consumption products are<br />
stored here, for which picking stations<br />
have been prepared adjacent to the conveyor<br />
belts.<br />
On the ground floor<br />

Advantages for PAVI‐Groupauto<br />
‐ Excellent use of space: it was possible to increase storage capacity and triple the floor space through<br />
the construction of two raised floors.<br />
‐ Integrated warehouse: each of the parts that make up the warehouse are integrated with each other.<br />
‐ Adjustable storage needs: the distribution of the racking can be changed if the turnover rate of a product<br />
varies or if the future needs of PAVIGroupauto so require.<br />
‐ Elimination of internal movement: as a result of the installed conveyor circuit and the optimal placement<br />
of the racking, it has been possible to eliminate part of the internal movement made by the operators.<br />
In this way productivity is increased and human errors are minimised.<br />
‐ Fast order picking: the storage system installed is highly flexible and allows the operator to have direct<br />
access to any product.<br />
‐ Efficient picking: operators can prepare orders by area using the continuous and automatic conveyor<br />
belt circuit that connects all the floors.<br />

Shuttle: finished products<br />
The Pallet Shuttle system is a version of<br />
compact solutions that offers maximum<br />
storage capacity, with the added advantage<br />
of having load channels with variable<br />
depths. Pallets are transported internally<br />
through the channels using autonomous<br />
shuttles, hence the system name.<br />
A totally automated version of Pallet Shuttle<br />
has been installed which uses a stacker crane as its<br />
transport equipment that lends to great speed<br />
and efficient stock control<br />
The version installed in the Hemosa warehouse<br />
is totally automatic and uses stacker<br />
cranes as its primary transport equipment<br />
between warehouse entry/exits and channel<br />
locations, lending to great speed and<br />
efficient control of both stock and operations<br />
done. The total capacity of this warehouse<br />
is 1,050 pallets, 1,200 x 1,200 mm<br />
in size with a maximum weight of 700 kg.<br />
The Mecalux Easy WMS is a system which<br />

Pallet Shuttle<br />
Stacker crane<br />
96 <strong>Best</strong> <strong>Practices</strong>
The Pallet Shuttle is housed on the cradle<br />
of the stacker crane in a position, slightly<br />
inferior to the pallet support level; said<br />
level is made up of two motorized chains<br />
which pick up and drop off the pallet in<br />
the entry/exit positions. When the stacker<br />
crane is positioned in front of the assigned<br />
location, the shuttle raises with the pallet<br />
on it and introduces it into the channel.<br />
It is placed on top of the support rail in<br />
the available location furthest from the<br />
aisle. The profile is also prepared to make<br />
movements guided by the Pallet Shuttle.<br />
Extractions are done in inverted order.<br />
The Pallet Shuttle is autonomous and<br />
charg es its battery in the cradle of<br />
the stacker crane in an automatic and<br />
straightforward manner. Each shuttle has<br />
eight wheels which provide the correct<br />
distribution of the weight upon the profile<br />
and which help it move smoothly from the<br />
stacker crane into the channels. On each<br />
side of the aisle, rails allow centering elements<br />
to facilitate the movement of the<br />
shuttle.<br />

Pallet entry and exit<br />
Two entry and one exit doors have been<br />
enabled. In each of these, a conveyor is<br />
entrusted to pick up and drop off pallets in<br />
the position which coincides with the aisle<br />
where the stacker crane circulates.<br />
Moreover, the doors are protected by<br />
rapid action vertical curtains that only<br />
open via a signal sent by the Easy WMS<br />
when the pallet passes through, avoiding<br />
changes in the internal temperature of the<br />
cold-storage.<br />
When the stacker crane is positioned in<br />
front of the conveyor, it sends a signal both<br />
to the corresponding conveyor, as well as<br />
to the one it carries in the cradle, in order<br />
to act in unison and move the pallet from<br />
one to another. It also emits a signal to the<br />
same Pallet Shuttle when it is positioned<br />
in front of the channel where it must perform,<br />
ordering its displacement and the<br />
operation to be done.<br />
The two located profiles on both sides of<br />
the channel are shaped to allow for double<br />
supporting functions both to the pallets<br />
and the guide rail, ensuring that the<br />
shut tle moves along safely.<br />
From the moment the operator drops off<br />
the pallet in one of the entry points and<br />
the system is indicated which reference it<br />
contains, Easy WMS takes over control of<br />
it and its internal management.<br />
The warehouse is a cold storage unit with<br />
temperatures kept slightly above 0 ºC, which conserves<br />
products deposited there in optimal condition<br />

Live Pallet Racking:<br />
semi-prepared fresh products<br />
This type of racking, as well as the Pallet<br />
Shuttle, is incorporated within the compact<br />
storage systems and also maximises<br />
space. The peculiarity of this warehouse<br />
is that it is composed of storage channels<br />
with a slight incline. Each channel has rollers<br />
on which the pallet, introduced into<br />
the more inclined side, moves along via<br />
gravity until the first position on the con<br />
trary side. The velocity of pallet movements<br />
of is controlled via roller brakes.<br />
Choosing said storage solution has to do<br />
with the type of products stored. Racks<br />
used for pallets with semi-prepared fresh<br />
products that need a perfect product<br />
turn over (FIFO). In order to achieve efficient<br />
turnover, live pallet racking is ideal<br />
be cause the first pallet to enter the channel<br />
is the first to leave.<br />

a direct connection between the warehouse<br />
and the production area. This was<br />
done via maximum automation of the storage<br />
processes in order to increase Zbyszko<br />
Company’s market competitiveness.<br />
The Zbyszko Company hired<br />
Mecalux to construct its newest warehouse<br />
located in the Polish city of Radom<br />
104 <strong>Best</strong> <strong>Practices</strong>
Connecting the production area<br />
and the warehouse<br />
Mecalux has set up an automated warehouse<br />
that connects the production area<br />
via a 100 m long overpass through which<br />
already palletised goods circulate on a circuit<br />
of roller conveyors.<br />
The checkpoint, located at the beginning<br />
of the circuit and within the same production<br />
area, verifies that the dimensions and<br />
the quality of each pallet are appropriate.<br />
The conveyors have two lines – one in each<br />
direction – working independently despite<br />
being placed in parallel.<br />
Inside the warehouse two levels of conveyors<br />
are arranged. The upper level is allocated<br />
to the input of goods, while the lower<br />
level has been reserved for outputs.<br />
There is also the possibility that outside<br />
goods, destined for the warehouse or the<br />
production area, can enter at this level. Not<br />
to mix operations, they have set up a conveyor<br />
just above the docks for inputs into<br />
the warehouse, with a lift placed at the end<br />
that raises the pallets to the upper level.<br />
On the ground floor, so that throughput is<br />
as high as possible, a circuit of electrified<br />
monorails capable of transporting SKUs<br />
at more than 100 m/min – and which links<br />
the warehouse with the preload area – was<br />
installed.<br />
This system is ideal for connecting distant<br />
points of the installation at a steady pace,<br />
eliminating unnecessary movements between<br />
rack areas.<br />

DAFSA, manufacturer of juices, vegetable<br />
purees and horchata, was established<br />
in 2006 as an exclusive provider to<br />
Mercadona, Spain’s top supermarket.<br />
Strong growth experienced in recent years<br />
has made DAFSA one of the most active<br />
companies within its sector. They turn on<br />
more than 250 million litres a year.<br />
In 2014, with the startup of the new production<br />
plant in Segorbe (Castellón), that<br />
has a 66,000 m 2 total surface area, it became<br />
their sector’s most advanced and<br />
sustainable production, processing and<br />
packaging factory in Europe. Within the<br />
premises, is the most noteworthy automated<br />
warehouse built by Mecalux.<br />
The collaboration between the two companies<br />
dates back to DAFSA’s beginnings.<br />
Since then, Mecalux has built different<br />

they go directly from production to linear<br />
supermarket shelves, avoiding interim<br />

Case study: Havi Logistics<br />
Mobile racks for continued growth<br />
at Havi Logistics<br />
Location: Italy<br />
Since its creation in Germany in<br />
1981 as a small family business, Havi<br />
Logistics has expanded its market to<br />
become one of the leading suppliers<br />
of integrated logistics services, with<br />
48 distribution centres in Europe<br />
and more than 5,000 employees. Its<br />
customers range from restaurant<br />
chains like McDonald’s to BP service<br />
station kiosks. The company is<br />
growing so fast that it has had to<br />
expand its facility in Lodi, Italy, and it<br />
has entrusted this project to Mecalux.<br />
Minding the essentials<br />
Havi’s logistics centre in Lodi, Italy, was<br />
opened in 2009 with a capacity for 4,566<br />
pallets. Given the company’s continuous<br />
growth and expanding customer base –<br />
and therefore the number of products to<br />
be stored and distributed – it quickly outgrew<br />
the facility. There was thus a clear<br />
need: to multiply the useful storage space<br />
by expanding the 4,870 m 2 available in the<br />
original warehouse.<br />
Furthermore, the characteristics of Havi<br />
Logistics’s activity had to be considered.<br />
Havi manages the supply chain for perishable<br />
and non-perishable products for a<br />
wide range of customers: frozen goods,<br />
fruits and vegetables, meat, dairy produce<br />
and cleaning products, amongst others.<br />
This made it necessary to conserve storage<br />
and handling areas with four different<br />
temperature ranges, with a particular focus<br />
on preserving the cold chain throughout<br />
the entire process to ensure optimal<br />
safety and conservation of the food that<br />
Havi stores and distributes daily.<br />
This project began with a very clear need:<br />
to reduce storage costs, especially in<br />
order to accommodate new customers.<br />
The result has been the combination of<br />
conventional pallet racks with mobile racking.<br />
By combining these two kinds of<br />
racks the size of the building needed to<br />
work with a given volume of pallets can be<br />
reduced.<br />
<strong>Best</strong> <strong>Practices</strong> 127
Case study I Havi Logistics<br />
The answer<br />
Mecalux’s technical team calculated the<br />
facility’s expansion and remodelling down<br />
to the tiniest detail. Since the customer’s<br />
priority was to multiply its storage capacity<br />
the Movirack mobile racks stole the<br />
show. These racks boast optimal performance<br />
at all temperatures. The immediate<br />
result was to expand from the original storage<br />
capacity of 4,566 pallets to the current<br />
capacity of 12,500 pallets, enlarging<br />
4,870 m 2 of surface area to 10,000 m 2 .<br />
As required by the customer, the four distinct<br />
zones with different temperatures at<br />
the Havi Logistics centre in Lodi were conserved,<br />
but the layout of each one was<br />
changed by implementing various storage<br />
solutions tailored to the specifications of<br />
the different products:<br />
- Dry or ambient temperature zone:<br />
370 linear metres of Movirack mobile<br />
racks were installed in this zone to a<br />
height of 9 metres. This system eliminates<br />
unnecessary storage aisles, as<br />
the operator selects the aisle that he or<br />
she needs to use, whether manually or<br />
by remote control, and the mobile racks<br />
move laterally on rails embedded in the<br />
floor. This leaves the space required for<br />
loading, unloading or picking access on<br />
the selected racks. Push-back racks for<br />
accumulative storage and conventional<br />
pallet racking were also installed. In this<br />
way, high occupancy was achieved and<br />
goods handling time was reduced.<br />
- Refrigerated zone: Movirack mobile<br />
racks combined with Push-back racks<br />
were installed here as well. This system<br />
allows four pallets per level to be placed<br />
in deep storage and uses the LIFO load<br />
management method (the last pallet<br />
in is the first out). The combination of<br />
both systems saves a significant amount<br />
of space and achieves high storage density<br />
while speeding the picking and replenishment<br />
of goods, which is essential<br />
in fresh food supply.<br />
- Freezing zone: in the cold storage area<br />
the Movirack mobile racks make it possible<br />
to reduce the volume that must<br />
be stored at low temperatures, thereby<br />
saving energy. Roller and trolley pushback<br />
racks and drive-in pallet racks were<br />
installed to round off this area.<br />
- Cool dock zone: this is a lengthwise<br />
loading and unloading zone linking<br />
the three storage areas described. Its<br />
function is to allow the goods to be handled<br />
without breaking the cold chain,<br />
which is kept at a temperature between<br />
1 and 4 degrees. This mode ensures that<br />
all products reach their destination in<br />
perfect condition.<br />
- Picking area without capacity loss:<br />
in this area there is a mix of conventional<br />
pallet racks, located on the sides,<br />
with Moviracks placed inside. The mobility<br />
and accessibility that the Movirack<br />
system offers frees up a wide aisle so that<br />
a forklift working with pallets can enter.<br />
It also opens all aisles so that operators<br />
carry out picking. Thereby, the area is set<br />
up to function both with pallets or smaller<br />
products that require picking.<br />
Mecalux has<br />
implemented a<br />
made-to-measure project<br />
that has allowed the<br />
Havi Logistics group<br />
to double the useful<br />
storage space and reap<br />
the benefits of a Movirack<br />
system on mobile bases<br />

Case Study I Hepco Motion<br />
The needs of the customer<br />
Hepco Motion, a British company that is<br />
part of the Hepco business group, has branches<br />
and accredited distributors throughout<br />
the world and more than 40 years of<br />
experience. The company offers a wide<br />
range of products that are constantly being<br />
updated to meet the demands of their<br />
customers within the automation and<br />
other industrial sectors, offering all kinds<br />
of innovative linear move ment solutions.<br />
Due to their continued growth rate, Hepco<br />
has recently launched an expansion of<br />
its production and storage facility headquarters<br />
in Tiverton, UK.<br />
Given that the old warehouse was used<br />
to expand production area, storage processes<br />
were moved to a new premises adjacent<br />
to the factory. In other words, the<br />
main goal put forward by Hepco Motion<br />
has been to optimise this new space, which<br />
is 53 m x 13.5 m x 6.5 m in size.<br />
Given product<br />
characteristics and<br />
the need to maximise<br />
storage capacity,<br />
the solution proposed<br />
by the Mecalux<br />
delegation in the UK<br />
(located in Birmingham)<br />
was to install cantilever<br />
racks on Movirack<br />
mobile bases<br />
The company entrusted Mecalux with the<br />
development and implementation of this<br />
storage project, so in addition to sorting<br />
out space requirements, it also took into<br />
consideration the specific nature of the<br />
product: profiles of various lengths.<br />
Another project requirement has been the<br />
reuse of stationary cantilever racks from<br />
the old warehouse, so that they could be<br />
integrated into the new facility.<br />
132 <strong>Best</strong> <strong>Practices</strong>
Case Study I Hepco Motion<br />
The solution proposed by Mecalux<br />
In all, nine Moviracks were installed,<br />
grouped in 3 blocks of 3 racks each. Each<br />
Movirack cantilever is 11 m long, which<br />
allows you to make full use of the 13.5 m<br />
wide warehouse.<br />
The three blocks of mobile rack were interspersed<br />
with the stationary cantilever<br />
racks for heavy loads that came from the<br />
old warehouse: two single, one on each<br />
end of the warehouse, and 5 double, with<br />
access on both sides.<br />
A cantilever system is the best option for<br />
the storage of different length profiles,<br />
because the cantilever arms that support<br />
load units allow for easy, safe handling. In<br />
addition, it is possible to adapt them to the<br />
size, stiffness, tolerance, weight, etc. of<br />
the goods.<br />
In respect to the Movirack mobile base system,<br />
its main feature is the automatic sideways<br />
movement along rails embedded into<br />
the floor. This takes up less space by eliminating<br />
unnecessary aisles, but without losing<br />
direct access to the products stored in<br />
the warehouse.<br />
Consequently, each of the 3 blocks of<br />
3 Moviracks installed only needs a single<br />
work aisle, instead of the 4 that would be<br />
needed in a conventional system.<br />
Taking into account that rack length is 11 m<br />
and aisle width is 2.6 m, this amounts to an<br />
overall space saving of more than 250 m 2 ,<br />
which has resulted in significant cost savings<br />
in the construction of the new building.<br />
The dimensions<br />
of the warehouse<br />
have been adjusted<br />
to the storage system,<br />
lining up the entry<br />
doors with the work aisles<br />
of the Movirack units<br />

Advantages for Hepco Motion<br />
- Higher productivity: the installation of mobile bases allows faster processing of inbound and<br />
outbound goods, optimising product placement and workflow.<br />
- Cost savings: the high-density nature of the mobile bases has made it possible to reduce the size<br />
of the new industrial building, requiring less surface area to achieve the desired storage capacity.<br />
The opportunity of combining mobile and stationary cantilever systems, by reusing old racks, has<br />
also resulted in cost savings.<br />
- Optimal warehouse management: the above benefits will improve the management of<br />
warehouse processes.<br />

Case study: Iron Mountain<br />
Earthquake-proof racking: an installation<br />
with conventional racking on the Pacific Rim<br />
Location: Chile<br />
The Mecalux racks installed in Warehouse 11 of Iron Mountain, a leading<br />
records management and archiving company, were the only ones which were<br />
able to withstand the 8.8 magnitude earthquake in 2010 that devastated the<br />
Chilean regions of Maule and Bio Bio. After the earthquake, Iron Mountain<br />
commissioned Mecalux to rebuild its many damaged buildings and to build two<br />
new warehouses with similar characteristics.<br />
<strong>Best</strong> <strong>Practices</strong> 135
Case Study I Iron Mountain<br />
The collaboration between the two companies<br />
began five months before the earthquake,<br />
when Iron Mountain hired Mecalux<br />
to build Warehouse 11, which holds more<br />
than 1.4 million boxes.<br />
As soon as Mecalux took over the project for<br />
Warehouse 11, the design went through a<br />
structural review that took a variety of considerations<br />
into account, such as local seismic<br />
regulations and fire protection, electrical<br />
protection and safety systems. The conventional<br />
pallet racking is designed with a focus<br />
on the seismic resistance of the shelves.<br />
Before starting the installation of the warehouse,<br />
the racks also went through a preliminary<br />
design phase, so they would be<br />
capable of absorbing the force generated<br />
by any potential earthquakes. The warehouse,<br />
divided into four floors in order<br />
to allow manual handling of the goods,<br />
is made up of tall, high-resistance racks<br />
with shelves at different levels on which the<br />
boxes containing the files are deposited.<br />
Access to the various floors of the warehouse<br />
is performed by means of stairs, lifts<br />
and walkways.<br />
136 <strong>Best</strong> <strong>Practices</strong>
Case Study I Iron Mountain<br />
The Iron Mountain<br />
warehouse in Chile is<br />
located in the Ring<br />
of Fire on the Pacific Rim,<br />
one of the regions with<br />
the most seismic activity<br />
in the world. Therefore,<br />
Mecalux prioritised the<br />
safety of the installation<br />
and built a reinforced<br />
system that would be<br />
capable of withstanding<br />
potential earthquakes<br />
The conventional pallet racks put in<br />
place were designed from the inside<br />
out – first the shelves and then the building<br />
envelope.<br />
Longitudinal rigid frames to reinforce the<br />
beams and columns on the four floors of<br />
the warehouse were also installed, along<br />
with the creation of a 4 m wide central<br />
aisle that enables comfortable handling<br />
of the load at the different locations. The<br />
central frames were fixed on a base plate<br />
calculated with sufficient thickness to provide<br />
maximum absorption of the shocks,<br />
since according to the calculations made,<br />
the seismic waves would travel longitudinally<br />
through the frames.<br />
The land on which Warehouse 11 was built<br />
was classified as Type 3, of the lowest possible<br />
quality, so extraordinary measures<br />
were taken to reinforce the entire building.<br />
The earthquake and the<br />
reconstruction<br />
On 27 February 2010, an earthquake measuring<br />
8.8 on the Richter scale struck the<br />
Chilean regions of Maule and Biobío with<br />
devastating consequences. The company<br />
lost seven of its facilities, but there was one<br />
that was indeed able to pass the test: the<br />
warehouse built by Mecalux, which was<br />
still only half-finished.<br />
Given this natural disaster, many businesses<br />
were looking to store their documents<br />
and files in more secure facilities such as<br />
those Iron Mountain had been proven to<br />
have.<br />
Even so, the company needed to relocate<br />
the many thousands of boxes that<br />
were scattered on the floor, so the second<br />
phase of construction was begun quickly<br />
with the aim of storing part of those<br />
loads. However, Iron Mountain not only<br />
needed to rebuild all its facilities, it also<br />
had to progress and keep growing. For<br />
this reason, the company commissioned<br />
Mecalux to build two warehouses similar<br />
to Warehouse 11, with a total capacity of<br />
more than 3 million boxes.<br />
With so little time to lose, Mecalux made a supreme<br />
effort to meet the deadlines and erect<br />
the new facilities at a dizzying speed, so that<br />
the company would be able to resume its<br />
activities as quickly as possible and relocate<br />
its personnel to their regular workstations.<br />
An efficient and safe project<br />
With this earthquake-resistant project,<br />
Mecalux demonstrated its high standards<br />
of quality, safety and commitment. The<br />
challenge of building a warehouse of this<br />
kind in such a powerful earthquake zone<br />
was overcome while complying with local<br />
seismic regulations and supplying an installation<br />
which was fully reinforced and prepared<br />
to protect the workers and stored<br />
goods against earthquake tremors.<br />
Mecalux also pledged to assist in the difficult<br />
tasks of reconstruction through the<br />
construction of two new warehouses<br />
which were equally resistant.<br />

Case study: Benco Dental<br />
Uprooting Benco Dental: a customized<br />
warehouse to speed up picking<br />
Location: USA<br />
In January 2010, dental equipment supplier Benco Dental teamed up with<br />
Interlake Mecalux (IKMX) to create the nucleus of its rapidly swelling<br />
business: a new home office doubling as a distribution centre and lavish<br />
product showroom. After a decade that saw the Pennsylvania company open<br />
distribution centres throughout the USA, Benco Dental’s next step was to bring<br />
the corporation back home.<br />
The founder Ben Cohen put down roots<br />
in Pennsylvania in the 1930s and formally<br />
started Benco Dental in a modestly sized<br />
Wilkes-Barre Township office. Benco grew<br />
the business there for the next 30 years. In<br />
Wilkes-Barre, the enterprise was hampered<br />
by, among other things, limited and<br />
undersized pick locations, pockets of<br />
scattered secondary stock, and bins with<br />
inefficient replenishment.<br />
“The most bang-for-your-buck happens<br />
when companies receive product, stick it<br />
in its primary location and pick it,” said a<br />
Benco spokesperson. “That’s the philosophy<br />
we took when we designed the new<br />
facility.”<br />
In its latest move, Benco swapped a<br />
6,400 m² installation for over 14,900 m²<br />
just 11 km away in Pittston.<br />

The fastest growing<br />
private dental distributor<br />
in the U.S. implemented<br />
a pick module as part<br />
of its expansion<br />
and legacy<br />
Mecalux steps in<br />
Bob Novak, Interlake Mecalux’s North East<br />
Market Manager, explained, explained<br />
that he first got involved with Benco Dental<br />
after one of its lift truck distributors came<br />
to him for help designing Benco’s pick module<br />
in Fort Wayne.<br />
He noted that after IKMX’s involvement<br />
with the Indiana installation, Benco Dental<br />
commissioned the well-known Spanish<br />
warehouse solutions provider to install<br />
racks in its future installations.<br />
As it often does, the evolution of this process<br />
started with Benco Dental’s conceptual<br />
drawings. After the sides volleyed<br />
their ideas back and forth, the concept was<br />
whittled down to a final design.<br />
“We went in as the experts on pick modules<br />
and have worked with Benco ever<br />
since,” said Novak. “It worked out pretty<br />
well,” top Benco managers replied, reflecting<br />

Challenge and success<br />
Relocating a company is a tough business,<br />
even if it only means moving 11 km<br />
away. The Pittston installation rests in a<br />
never-occu pied building within a storage<br />
park that was adapted by Interlake<br />
Mecalux (IKMX) according to Benco’s<br />
specifications.<br />
Benco Dental’s team realized how tricky<br />
the several months preceding the<br />
move were going to be. It meant having<br />
to manually move 34,000 items oneby-one<br />
from old pick slots to new ones.<br />
“Maintaining customer satisfaction during<br />
the move was the biggest challenge,”<br />
Benco management explained, “We didn’t<br />
shut down for one day.”<br />

Benco Dental reinvented<br />
The design and size of Benco Dental’s installation<br />
ensures that it isn’t strained by<br />
constant restocking demands. Warehouse<br />
dimensions aside, the dental product distributor<br />
uses its space wisely by also building<br />
up and canvassing each square meter<br />
with efficient operations.<br />
Benco’s floor plan certainly fulfils all of its<br />
basic requirements, but it is the system’s<br />
bells and whistles that add a unique efficiency<br />
exclusive to that Pittston facility.<br />
In addition to the improvements the racks<br />
inherently create on the premises, the expert<br />
innovations and specialized flourishes<br />
of the Pittston location optimize<br />
production.<br />
Mobilizing Mecalux’s knowledge into innovative<br />
solutions is what helped solidify<br />
Pallets arrive on<br />
the outer decks of the<br />
module to be loaded<br />
on to the flow rails<br />
Benco. “I approached Interlake Mecalux<br />
with a basic design in mind, they tweaked<br />
it, and we both added some great features,”<br />
said a key Benco manager.<br />
Here are Pittston’s biggest customisations<br />
– and why they are necessary:<br />
Adjustable decks: make it easier for anyone<br />
to stock top shelves. The solution was<br />
to incline the deck on the higher end of the<br />
carton flow module by several inches and<br />
install multiple catwalks connecting the<br />
two. The end result is a seamlessly equal<br />
reach for personnel on both sides.<br />
An overpass: in addition to the catwalks,<br />
Novak and the IKMX design crew<br />
were able to create an overpass connecting<br />
the second floor of the pick module<br />
with a structural mezzanine for greater<br />
throughput.<br />
Extra shelf picking area: the design also<br />
called for shelf pick areas allowing for<br />
maximised order fulfilment or just-in-time<br />
shipping. Shuffling the product out<br />
the door or back into the system is easier<br />
to do the more shelf picking areas one has.<br />
Once a pallet is unloaded onto the dock,<br />
lift trucks transport the pallets to their locations<br />
throughout the module.<br />
Steel-encased flow rail: the ground level<br />
pallet flow rails were last-minute additions<br />
designed to maintain a productive picking<br />
speed of oversized products. It keeps product<br />
both stored and out of the way, and<br />
protects against possible damage done by<br />
lift trucks.<br />
V-shaped shelves: Benco Dental wanted<br />
their smaller, slower-moving products<br />
to be accessible to the pick area without<br />
going to great lengths to retrieve them – a<br />
common wish among facilities with similar<br />
products. For this, the group designed<br />
V-shaped shelves. The 20-inch deep units<br />
hang above the conveyor – accessible, but<br />
out of the way.<br />
Bonus storage: adding more storage space<br />
to each level meant that Benco would<br />
have extra floor space where pallet storage<br />
would have been.<br />
The extra floor space can be used by forklifts<br />
to unload additional goods faster.<br />
The stocking area rises 10 inches between<br />
the picking side and the charge side.<br />

CYCLING THROUGH A RESPONSIVE REPLENISHMENT METHOD<br />
Benco Dental has made it a company practice to saturate its distribution centers with efficient production strategies<br />
including its just-in-time replenishment method. JIT is a means to reduce stored inventory by optimizing system<br />
performance. Here is how Interlake Mecalux helped ensure Benco Dental’s efficiency:<br />
1. Product is<br />
received within<br />
24 hours<br />
Reduce store inventory by<br />
optimizing the time it sits in the<br />
factory, eliminating “change<br />
overtime” that would normally<br />
cause delays at the beginning of<br />
the process.<br />
2. Expedited<br />
product is sent<br />
straight to order<br />
fulfillment<br />
Schedules are synchronized with<br />
demand. If there is not product<br />
demand, personnel is placed<br />
else where, making multi-skilled<br />
employees more useful.<br />
6. Product is<br />
unloaded to dock<br />
Fewer pieces mean fewer delays.<br />
3. Remaining stock<br />
is stored<br />
With less inventory, there is<br />
decreased risk of product damage<br />
or expiration.<br />
5. Employee effort,<br />
emphasis is spent elsewhere<br />
Supplier relationships are enhanced as a company<br />
with limited inventory will do whatever it takes to<br />
avoid part shortages.<br />
4. Fulfilled orders loaded<br />
and shipped<br />
When production demand and supply is<br />
synchronized and goods move directly from<br />
receiving to order fulfillment, less space is necessary<br />
for storage.<br />

Logistics software: the cloud is the future<br />
Due to the continuous evolution of technology, our business<br />
landscape is changing at a high speed. One of the most important<br />
paradigm changes that has taken place in recent years has been<br />
caused by the software industry, with the creation of cloud-based<br />
applications. The logistics operations of companies have quickly<br />
adapted to this change, demanding that software applications be<br />
implemented which are increasingly compatible with the cloud.<br />
This paradigm shift has been led principally<br />
by the needs of the clients themselves,<br />
who in light of periods of crisis have opted<br />
for the type of solutions that only the cloud<br />
can offer: controlled expenditure, versatility<br />
and portability.<br />
However, it is also important to take into<br />
account the fundamental influence that the<br />
evolution of technology has brought upon<br />
us, which has made it possible to increase<br />
the connection capacity both within locally<br />
or mobile based communications. The<br />
social changes caused by globalisation, the<br />
sharing of information and the need for<br />
continuous access to information can also<br />
not be ignored.<br />
What do we mean when we talk<br />
about “the cloud”?<br />
There are many definitions for such a broad<br />
term and that, in the here and now, is part of<br />
almost any solution. Perhaps the one that comes<br />
closest says that it is a “consumer technology<br />
model” (applications, computing<br />
and storage) as a service through a network<br />
(usually the Internet), without the need for<br />
investments, securely and accessible from<br />
anywhere. This virtual set up makes data<br />
control and management more obtainable.<br />
Key advantages<br />
The main features that have led to this<br />
growth in cloud based solutions are:<br />
• Savings in the initial investment of<br />
any project of software deployment.<br />
The hardware infrastructure to house the<br />
solution is eliminated, and only the equipment<br />
in use is required. Nor is the initial cost<br />
of licensing necessary, since a payment by<br />
use and monthly service (SaaS) is applied.<br />
• Automatic and secure application<br />
updates. There is no need to spend several<br />
weeks to update a company’s applications,<br />
with problems that can result in loss of data,<br />
downtimes, etc. Updates are completely<br />
transparent and without any form of<br />
intervention.<br />
• Savings in maintenance costs. By<br />
adopting a SaaS model, the maintenance of<br />
the application and the housing of the solution<br />
lies with the provider. Who is the one<br />
responsible for hardware upkeep.<br />

ON-PREMISE<br />
• Flexibility. This model is ideal for businesses<br />
with fluctuating growth over time,<br />
so that it is always possible to increase or<br />
decrease the service you are receiving.<br />
• Access to information from any location.<br />
Only an Internet connection is required<br />
to be able to work remotely.<br />
• Reduction of the implementation<br />
times when performing a solution rollout<br />
because it is unnecessary for clients to install<br />
software to access the computer program<br />
from an Internet browser.<br />
• Security. The cloud does not depend on<br />
computer equipment, so that data is not<br />
lost in the event of portable devices being<br />
misplaced, or because of any type of breakdown<br />
in a client’s computer. That is to say,<br />
because the data is stored in the cloud, you<br />
can access the information in the company,<br />
regardless of anything that happens to your<br />
computer.<br />
Some “cons”<br />
All these features are advantages that currently<br />
lead more than 60% of medium-sized<br />
companies to use cloud-based services.<br />
But there are also drawbacks to working in<br />
the cloud:<br />
• Dependence of network connections.<br />
For this reason, before deciding to step into<br />
the cloud, you should verify that your network<br />
infrastructure, that will support these<br />
services, is adequate enough and even be<br />
sure to have a contingency plan for network<br />
breakdowns. This way, you will get a solid<br />
system.<br />
• Loss of data control. This is the biggest<br />
drawback that many companies face when<br />
making the leap into the cloud. To upload<br />
information into a server hosted in the cloud<br />
that can be replicated in any other secure<br />
backup in the recovery of a system, relocation<br />
of the information is clear and this<br />
makes many businesses fearful. This distrust<br />
is based, in part, on the perception that data<br />
is more secure in their own facility, when the<br />
truth is that it is easier for data leaks to occur<br />
at a domestic level. The possibility of an incident<br />
within their own systems is much more<br />
likely than with any cloud hosted service.<br />
An example of evolution: Easy WMS<br />
Fundamentally, when analysing the pros<br />
and cons of using the cloud, it is obvious<br />
that the future of software and services<br />
lies within this new platform. In the coming<br />
years, companies will increasingly rely on<br />
adopting this technology.<br />
Responding to the changing needs of its<br />
customers and to this new paradigm, Mecalux<br />
Software Solutions – Mecalux’s software<br />

new version of its Easy WMS Warehouse<br />
Management Software, so that clients can<br />
operate as per the architecture that they<br />
desire to use:<br />
• Either in the cloud, offering a cloud service<br />
model, namely SaaS (Software as a<br />

Clad-rack warehouses<br />
When racks also support the building<br />
This type of constructions are integrated buildings formed by the racks themselves, whose structure is<br />
coupled to both the roof and wall cladding. Clad-rack warehouses have achieved great importance in<br />
the last 30 years, mainly because of the need for space optimisation, and resulting in the construction of<br />
buildings that are taller than 45 m.<br />
In order to better understand the advantages<br />
offered by building a clad-rack<br />
warehouse, we should first consider some<br />
features of the traditionally built warehouses:<br />
• The building of a traditional warehouse<br />
is formed by a supporting structure, with<br />
its pillars, trusses, roof girders, side walls<br />
and roofing, on which external forces<br />
such as the wind, snow or earthquakes<br />
act against, depending on its geographic<br />
location.<br />
All the forces are transmitted to the<br />
ground through the pillars, which require<br />
the construction of load-redistribution<br />
footings.<br />
It is also essential to build a slab or floor<br />
with sufficient load capacity to be able to<br />
support the weight of the goods and handling<br />
equipment.<br />
• The warehouse, or one of its parts, is<br />
composed of racks that occupy the total<br />
height of the building’s interior.<br />
• There are usually heavy pallets stored on<br />
the racks, so calculations must be done to<br />
withstand all the stored goods.<br />
• The racks are metal structures that have<br />
a large number of pillars (frames/uprights)<br />
that distribute the weight evenly on the<br />
floor of the warehouse.<br />
• The forces that the racking units transmit<br />
to the ground are much higher than<br />
those that the pillars of the building transmit,<br />
although individually. Each upright<br />
transmits a much lighter load and which,<br />
above all, is distributed.<br />
• If the external forces that support the<br />
building were transmitted to the ground<br />
via the racks, it would add a relatively small<br />
percentage to each upright in comparison<br />
with the loads derived from the goods.<br />
Advantages of a clad-rack<br />
warehouse<br />
• Full use of the surface area: the warehouse<br />
is designed at the same time as the<br />
racks and only occupies the space required,<br />
without intermediate pillars that influence<br />
their distribution.<br />
• Optimisation of height: as with the<br />
surface area, the height will be only that<br />
which is required. At the same time, the<br />
upper trusses or girders require less height<br />
and incline being directly supported on<br />
the racking.<br />
• Maximum height of the construction:<br />
you can build to any height, it only<br />
depends on local regulations or the scope<br />
of the handling means which are used, being<br />
able to exceed 45 m high (which would<br />
148 <strong>Best</strong> <strong>Practices</strong>
Our experts I Clack-racks<br />
be complex and expensive in traditional<br />
construction).<br />
• Simpler construction: the entire structure<br />
is assembled on a concrete slab of suitable<br />
thickness to achieve uniform distribution<br />
of the forces on the foundation; there isn’t a<br />
high concentration of loads<br />
• Less time for completion: once the<br />
slab is built, the entire structure and cladding<br />
are progressively and concurrently<br />
installed.<br />
• Cost savings: As a general rule, the<br />
cost of a clad-rack warehouse is less than<br />
the more traditional racks. The greater the<br />
construction height, the more profitable<br />
the clad-rack system.<br />
• Easily removable: being a structure<br />
formed by standard rack elements that come<br />
pre-assembled or bolted, they can be<br />
dismounted with ease and a high percentage<br />
of components recovered.<br />
When installing a clad-rack<br />
warehouse<br />
The variety of applications of this type of<br />
warehouses are very broad, although it<br />
is particularly suitable solution in the following<br />
cases:<br />
• When the warehouse exceeds 12 m high.<br />
• When the construction is of a lower, but<br />
its use is temporary or pro-visional.<br />
• When the maximum optimisation of space<br />
and volume is required, regardless of<br />
the height of construction that is built.<br />
In the case of clad-rack warehouses which<br />
are less than 12 m high, the storage system<br />
which is often used is non-automated<br />
• Minimal civil works: it only requires<br />
the construction of the slab on the ground<br />
and, in some cases, a waterproof wall between<br />
one and two metres high. In which<br />
case the operations area needs to be expanded<br />
for receipt and dispatch, a traditional<br />
building can be built, but of sufficient<br />
height without reaching the total height of<br />
the warehouse.<br />

roof overloads, seismic action, etc.), but<br />
also the specific regulations for the metal<br />
racking.<br />
compact (drive-in palletising, push-back,<br />
Pallet Shuttle and live by gravity).<br />
racks must also bear the forces that they<br />
transmit.<br />
On a European level, the following regulations<br />
are in force for all metal structures:<br />
The use of conventional pallet racking, either<br />
single or double-depth, is more common<br />
starting at this height. On the other<br />
hand, when above 15 m high handling<br />
machines should be automatic.<br />
As a general rule, in the case of automated<br />
warehouses, the best practice is to take advantage<br />
of the maximum height allowed<br />
by local regulations. This is provided that<br />
the amount of machines designed for the<br />
installation makes it possible to achieve<br />
the desired number of movements. To get<br />
same storage capacity, you can opt for a<br />
reduced height installation, but with more<br />
work aisles –which involves installing more<br />
machines–or opt for a warehouse with<br />
more height and less aisles, and therefore<br />
less machines.<br />
Basic components<br />
of a clad-rack warehouse<br />
The constructive system is very simple: the<br />
structure is composed by the racks themselves<br />
on which the upper trusses, roof<br />
girders and the side profiles are placed,<br />
which are used for attaching the panels<br />
that make up the walls and roofing.<br />
When the handling equipment are automatic<br />
stacker cranes, the upper guides<br />
are attached to the trusses, so that the<br />
How a warehouse clad-rack<br />
is calculated<br />
Apart from having to bear loads generated<br />
by the goods stored and the forces from the<br />
handling machines, clad-rack warehouses<br />
must also be designed to withstand the actions<br />
of a building, for example, the action<br />
of the wind, overburdened roofing (maintenance,<br />
snow, etc.), the weight itself and<br />
of the wall cladding – both covering and the<br />
facades – besides considering the seismic<br />
coefficient that corresponds to the zone<br />
where it is installed.<br />
As with any civil engineering structure,<br />
the clad-rack warehouse forms part of the<br />
building structure. However, this involves<br />
very specific constructions, because in<br />
addition to the peculiarities of a building<br />
used, the specifications of the racks must<br />
be taken into account.<br />
Thus, when calculating and designing the<br />
structure of a clad-rack warehouse, not<br />
only must each country’s rules of construction<br />
and the actions that can affect<br />
• EN 1990 / Basis of structural design.<br />
• EN 1991 / Eurocode 1: Actions on<br />
structures.<br />
• EN 1993 / Eurocode 3: Design of steel<br />
structures<br />
• EN 1998 / Eurocode 8: Design of structures<br />
for earthquake resistance.<br />
Logically, in each territory there are different<br />
climatic actions that involve deviations from<br />
the general rule. Moreover, certain countries<br />
require different calculation conditions<br />
(for example: more stringent security coefficients<br />
than those specified in European<br />
regulations).<br />
In regard to the European regulations specific<br />
to metal racking, the following are<br />
underscored:<br />
• EN 15512 / Steel static storage systems.<br />
Adjustable pallet racking systems. Principles<br />
for structural design.<br />
At the height of 12 m the inflection point between<br />
the costs of constructing a traditional warehouse and<br />
a clad-rack warehouse is usually found<br />

• EN 15635 / Steel static storage systems.<br />
Application and maintenance of storage<br />

The structure of a clad-rack warehouse is<br />
composed of thousands of junctions and<br />
rods, so you need powerful calculation<br />
programs to model and calculate this type<br />
of installation in three dimensions. 3D modelling<br />
is indispensable if we want to predict<br />
the torsional effects that a simplified<br />
analysis in two dimensions cannot reveal.<br />
Calculation programs allow.<br />
by regulation EN 15620 must also be substantiated<br />
in two dimensions.<br />
It is important to point out that the calculation<br />
of a clad-rack warehouse is an<br />
iterative process. Which means that the<br />
person calculating uses some profiles and,<br />
subsequently, checks and verifies their<br />
appropriateness. This process is repeated<br />
until getting the most finely-honed solution<br />
possible, that meets all safety requirements<br />
and that delivers maximum profitability.<br />
The iterative process will be longer<br />
or shorter depending on the experience of<br />
the person calculating.<br />
Civil works and assembly<br />
The basic civil work is minimal: only the<br />
slab on which the structure sits and the pipes<br />
for the drains are required. Likewise,<br />
depending on its use, a water-proof perimeter<br />
wall and an additional operations<br />

• To obtain the forces that the racks bear:<br />
bending, shearing and axil moments on<br />
each rod and each junction.<br />

of all the structure’s components.<br />

area of appropriate height can be erected,<br />
as has already been mentioned.<br />
In the process of the structure’s assembly,<br />
the first job that is performed on site is the<br />
verification of the correct levelling of the<br />
slab, after which part of the anchor plates<br />
are placed in their final position (before<br />
putting up the structure). Once you have<br />
verified the correct levelling of the racks,<br />
you can fill the space between the plate and<br />
the ground with a non-shrink concrete.<br />
The next step is to assemble the structure.<br />
You can install any type of pallet storage<br />
system, both single and double-depth, with<br />
live racks, with or without Pallet Shuttle and<br />
in combination with stacker cranes or transfer<br />
cars. It is also possible to install clad-rack<br />
warehouses for boxes, particularly suited in<br />
combination with the miniload automated<br />
system (stacker cranes for boxes).<br />
The assembly usually starts at the head of<br />
the warehouse and, after putting up the<br />
first racks and part of the cladding (the<br />
coverings and facades), the handling machines<br />
are introduced. Then, the structure<br />
is finished being assembled and the rest of<br />
the cladding is placed.<br />
The requirements of clad-rack warehouse<br />
can vary depending on several factors. For<br />
example, when used as cold storage, two<br />
The slab must have suitable strength and thickness<br />
for bearing the weight of the structure plus the goods<br />
stored, as well as to withstand the forces produced by<br />
external factors<br />
slabs are built – one on top of the other –<br />
and you install insulation between them.<br />
At the same time, the bottom slab incorporates<br />
a ventilation system, or a circuit<br />
of pipes, to prevent the foundation from<br />
freezing.<br />
Another determining factor is height.<br />
When more height is required than is<br />
allowed by applicable regulations, there<br />
is the possibility of building part of the<br />
warehouse in a trench. In these cases,<br />
provisions for a hatch or door must be<br />
made for maintenance workers and the<br />
installation of access ladders, drains and<br />
over-flow water pumps.<br />
On other occasions, height will be determined<br />
by factors such as the wind or<br />
the seismicity that affects the zone. The<br />
repercussions of this factor will be greater<br />
the higher the warehouse, the vertical<br />
bracing has to transmit forces produced<br />
in the structure along to the concrete slab<br />
that makes up the floor.<br />

Integration<br />
of the warehouse<br />
In general, warehouses are built next to<br />
other production processes. When the<br />
constructive system is self-supporting,<br />
even more so if the handling machines<br />
are automatic, the height is usually much<br />
higher than the rest of the buildings<br />
and the site it is located at has been well<br />
analysed.<br />
It is essential to install the warehouse in a<br />
strategic zone, to simplify the flows between<br />
the different areas that have been<br />
connected as much as is possible. This will<br />
be easier when it is a part of a totally new<br />
plant, and according to the experience<br />
and know-how of the designer.<br />
Although the majority of the warehouses<br />
are joined to the production buildings, there<br />
are situations in which the warehouse<br />
will be more distant: for logistical needs,<br />
or future expansion, or to not eliminate inner<br />
lanes. To connect the warehouse with<br />
other buildings, you may resort to any of<br />
these options:<br />
1. Have shuttle trucks that connect the production<br />
centres with the warehouse. The<br />
logical thing to do in this case is that the<br />
vehicles and the warehouse are ready to<br />
perform unloading automatically.<br />
2. Build an underground tunnel to connect<br />
the two areas via conveyors.<br />
3. Build an overpass on a raised structure.<br />
Conclusion<br />
The possibility of configuring the warehouse<br />
with different types of storage systems<br />
for pallets and for boxes, both manual<br />
and automatic, allows you to respond<br />
to all types of loading units, operations<br />
and necessities.<br />

How to calculate the structure<br />
of a conventional pallet rack<br />
What forces must be pondered when designing metal pallet racks? How do we verify that the structure<br />
will be suitable to withstand all loads? These and other <strong>issue</strong>s are those which should be taken into<br />
account in the design of this type of rack, with the goal of ensuring its stability and resistance, and<br />
therefore the overall security of the installations.<br />
The European EN 15512 norm, according<br />
to its definition, specifies the requirements<br />
for structural design applicable to conventional<br />
pallet racking (selective racks)<br />
manufactured from steel components,<br />
designed to store palletised unit loads and<br />
subject to essentially stationary loads. It<br />
has become the main benchmark on this<br />
matter, and provides additional technical<br />
information required for the implementation<br />
of the Eurocodes.<br />
In addition, designers must also provide<br />
for the EN 15620, EN 15629 and EN 15635<br />
standards as guides for the specifications<br />
of the storage system, the required tolerances<br />
during assembly and the safe operation<br />
of the installation.<br />
Likewise, conventional racks for palletised<br />
loads are metal structures, generally<br />
formed by components made out of thin,<br />
cold-formed, steel sheet metal. They are<br />
able to withstand heavy loads, while the<br />
installation is designed to be as lightweight<br />
as possible; consequently the rack’s own<br />
weight rarely exceeds 5% of the load stored<br />
in the facility’s interior.<br />
On the other hand, it is imperative that this<br />
type of installations for palletised loads be<br />
versatile, to be able to adapt to different<br />
load types. For this reason, the connections<br />
between the main parts of the structure<br />
must be adjustable, and quick and<br />
easy to assemble.<br />
The uprights of these structures usually<br />
have perforations along the entire profile,<br />
while the beams include connectors provided<br />
with hooks that fit into the perforations<br />
of these uprights.<br />
Basic structural<br />
components<br />
• Frames: are vertical pieces composed<br />
of two uprights joined together by beams<br />
and cross-ties forming a lattice.<br />
Close up of the<br />
joining of an upright<br />
and a beam<br />
• Uprights: these tend to be cold-profiled<br />
components of thin sheet metal, with<br />
open sections and are always perforated,<br />
which makes them prone to distortion and<br />
torsional type sagging.<br />
• Beams: are horizontal pieces that bear<br />
the burden of the pallets. These tend to<br />
be cold-profiled and have connectors on<br />
their ends for attaching them to frame<br />
uprights.<br />
• Connectors: are parts welded onto<br />
the ends of beams to attach them to the<br />
uprights. They are equipped with hooks<br />
that fit into the perforations of the<br />
uprights.<br />

Calculation types: general and<br />
individual<br />
The calculation is carried out in two<br />
stages:<br />
1. General analysis of the structure<br />
Normally filiform, two-dimensional (2D)<br />
models with second order calculations<br />
applying the finite element method are<br />
used. In some types of installations, calculations<br />
are also frequently done via 3D models<br />
in accordance with the EN 1993-1-1.<br />
This analysis must incorporate the modelling<br />
of the actual behaviour of the connection<br />
between the upright-beams and<br />
the frame-ground.<br />
Example of down‐aisle analysis<br />
2. Individual verification of pieces<br />
Once the overall analysis is performed, it is<br />
vital to check the correctness of the design<br />
by verifying the buckling and the tensions of<br />
the pieces that make up the racking.<br />
Basically, the following items are verified:<br />
- General stability of the installation.<br />
- Stress state of frames: uprights and<br />
diagonals.<br />
- Base plates: pressure on the slab and<br />
anchorage.<br />
- Beams: buckling and stress state.<br />
- Connectors.<br />
General analysis: structural model<br />
For general analysis, it is usual to consider<br />
two, two-dimensional (2D) structures in<br />
concurrent vertical and perpendicular layouts<br />
with respect to the storage aisles.<br />
In the model calculation, the following requirements<br />
are observed:<br />
General analysis<br />
• Filiform model.<br />
• System lines through the CG (centre of<br />
gravit y) of the gross sec tion, or also through<br />
the CG of the actual cross section.<br />
Overall analysis of a 2D structure<br />
Example of cross‐aisle analysis<br />
• Terms of section corresponding to the<br />
gross section of the pieces (or also of the<br />
actual cross section).<br />
In this analysis the aim is to obtain:<br />
- The internal forces on the different pieces<br />
for their subsequent verification,<br />
combining the down-aisle and crossaisle<br />
calculations.<br />
- Checking the overall stability of the<br />
installation.<br />
It includes two types of analysis:<br />
- Down-aisle analysis: analysis in 2D on a<br />
vertical layout parallel to the load aisles.<br />
This analysis also includes the semi-rigid<br />
connections of the upright-beam and<br />
upright-floor, obtained by testing.<br />
- Cross-aisle analysis: analysis in 2D on a<br />
vertical layout perpendicular to the load<br />
aisles. Usually involves the articulated<br />
upright-floor joint.<br />
In both cases, the global imperfection can<br />
be modelled as:<br />
- The tilt of the agreed uprights to the<br />
imperfection.<br />
- Horizontal forces at the height of<br />
the load levels corresponding to the<br />
imperfection.<br />
Type of analysis according to the<br />
classification of the structure<br />
This classification is based on the relationship<br />
of the expected load design in regards<br />
to the critical load of the structure. According<br />
to the coefficient obtained by this re-<br />

lationship, the need to perform a second<br />
order calculation will be determined.<br />
Individual analysis: verifying<br />
elements<br />
In the verification of the different elements<br />
that make up the structure the following<br />
concepts, among others, must be taken<br />
into account:<br />
Uprights - Frames - Anchorage plates<br />
- Upright mainly function by compression<br />
and flexion.<br />
- The use of the reduction factor for buckling,<br />
obtained by laboratory testing or<br />
by using theoretical formulas.<br />
- The internal forces obtained from the<br />
down-aisle and cross-aisle calculations<br />
will be jointly perpended.<br />
- Axil force on the diagonals of the<br />
frame.<br />
- Axil force and momentum on uprights’<br />
footplates.<br />
- Axil and shear force on fastening anchorage<br />
to the slab.<br />
Beams - Connectors<br />
- Working primarily with bending and<br />
shearing forces.<br />
- Buckling (deflection) is limited to a maximum<br />
of L/200. Occasionally, for certain<br />
installations smaller value deflections<br />
are required.<br />
So that the conventional<br />
pallet racking function<br />
safely, it is fundamental<br />
to know the structure<br />
you are working with,<br />
the preventive actions<br />
that exist and the safety<br />
measures to keep in mind.<br />
- Consideration of the cross-aisle forces<br />
of location.<br />
- Verifying the shear force and deflection<br />
in the endplate.<br />
Blocks of bracing - Vertical and horizontal<br />
bracing - Spacers<br />
- The brace diagonals work exclusively on<br />
axil force.<br />
- Verification of the deflection and shear<br />
forces on the elements that connect the<br />
diagonals of the vertical bracing to the<br />
frames (bracing spacers).<br />
- The actions of the bracing increases the<br />
forces on the uprights and beams that<br />
form part of the block of bracing or that<br />
are adjacent to it.<br />
- The eccentricity of the actions of the<br />
vertical bracing in respect to the racks<br />
requires a study of the torsion behaviour<br />
of the elements that form part<br />
of the block of bracing, as well as the<br />
racks.<br />
Actions<br />
There are different types of actions that<br />
may affect the strength and stability of<br />
the racks, so that it is also imperative to<br />
contemplate them when setting up an<br />
installation of this kind. The actions on the<br />
racking are classified into several groups:<br />
Permanent actions<br />
- Weight of the racks.<br />
- Permanent loads and various equipment<br />
supported by the racking.<br />
Variables actions<br />
- Weight of the pallets.<br />
- Weight and actions due to mobile loads<br />
on platforms and walkways.<br />
- Actions due to the location of the pallets<br />
(vertical + horizontal).<br />
- Actions on the positioning profiles.<br />
- Actions due to storage equipment<br />
guides.<br />
- Actions due to the imperfection in the<br />
elements and assembly.<br />
- Other actions arising from national regulations<br />
(wind, snow, etc.).<br />
- The weight of the pallets together with<br />
the general imperfection deemed as a<br />

In each of the load cases the tensional<br />
state of components subjected to the corresponding<br />
weighted actions (affected<br />
by factors of security) is studied. In the<br />

combination of forces (down-aisle + crossaisle)<br />

considering the following actions or load<br />
cases:<br />
• Permanent actions + the most unfavourable<br />
variable action.<br />
• Permanent actions + 0.9 x (the totality<br />
of variable actions).<br />
• Permanent actions + variables + incidentals.<br />
State Service Limit (SSL)<br />
In each of the load cases the buckling of the<br />
It is also necessary to ponder the uncertainty<br />
as to the different actions that can<br />
affect the racking (described previously).<br />
To do this, there are established security<br />
coefficients considered, for both the load<br />
coefficient and the material, and which<br />
can range between 1.0 and 1.5.<br />
Some countries have specific national legislation<br />
which obliges you to use greater<br />
weighting coefficients in the facilities that<br />
are built on its territory (A deviations).<br />

En 15620. - Steel static storage<br />
systems. Tolerances, deformations<br />
and clearances.<br />
- Flatness of the slab and its buckling under<br />
load.<br />
- Clearance between pallets, and between<br />
the pallet and racks.<br />
- Clearance between racks and civil<br />
works.<br />
- Aisle width according to the load unit,<br />
the forklift type and the number of pallet<br />
locations per hour.<br />
The asymmetrical position of the pallets in respect to the beams.<br />
matically become off-centred, the increased<br />
load that causes this off-centring on<br />
beams and braces must also be taken into<br />
account in the design of the structure.<br />
Likewise, the eccentricities of the lines of<br />
the structural system must be observed, in<br />
the event that they are deemed excessive.<br />
Eccentricities in the positioning of<br />
the pallets<br />
- Asymmetric position of the pallets in regard<br />
to the beams.<br />
- Load is not evenly distributed on the<br />
pallet.<br />
- Load overflow in regards to the pallet.<br />
Thus, not only is it imperative for the manufacturer<br />
to carry out a good structural<br />
analysis and design of the installation,<br />
but it is also makes good use of the same,<br />
so that actions against the racking<br />
does not exceed those considered in the<br />
installation’s structural calculation. This is<br />
all the fruit of many years of experience,<br />
and studies and trials by FEM (Federation<br />
of European Maintenance) and other<br />
agencies.<br />
It is essential to keep in mind:<br />
En 15629. - Steel static storage<br />
systems. Specification of storage<br />
equipment.<br />
Individual responsibilities of the different<br />
system suppliers that make up the storage<br />
equipment.<br />
En 15635. - Steel static storage<br />
systems. Application and<br />
maintenance of storage equipment.<br />
- Designation of a person responsible for<br />
the security of the storage equipment.<br />
- Safe load sign.<br />
- Education and training of the warehouse<br />
staff.<br />
- Damage to the racks and assessment of<br />
the level of damage.<br />
- Regular inspections. u<br />
Eccentricities of the diagonals of the<br />
vertical bracing<br />
Although the diagonals of the vertical bracing<br />
are not physically connected to the<br />
racks on the junctions that form the neutral<br />
lines of the uprights and the beams,<br />
in the 2D calculations the diagonals can<br />
be viewed as attached to these junctions,<br />
provided that the eccentricities of the same<br />
are kept below certain values depending on<br />
the width of the brace and the edge of the<br />
beams. The same happens with the diagonals<br />
of the frames.<br />
Conclusion: the safety of the<br />
installation and responsibilities<br />
Lastly, we want to point out that in a large<br />
part of the incidents that occur in palletised<br />
installations, human error interferes<br />
and are primarily caused by scraping or<br />
impacts of forklifts against the racking.<br />
On the other hand, these impacts may<br />
represent higher than normal actions on<br />
the racks, than those established in the EN<br />
15512 norm.<br />
Software for the structural calculation of racks<br />
Currently, all the mentioned analysis throughout this article are done via<br />
computerised calculation programmes. Mecalux has applied their extensive<br />
experience in design, manufacture and installation of warehouse systems to the<br />
development of a powerful design software, capable of finding the best option<br />
for each warehouse layout, the dimensions of the storage structures and the most<br />
ideal profiles. In this way, optimization of capacity and cost of the warehouse is<br />
procured, with the utmost safety.<br />
