Goods are Always on the Move<br />
Perfect Logistics Requires Perfect Solutions<br />
<strong>Port</strong>s are interfaces in a complex<br />
chain of logistical stations where not<br />
only containers and general cargo<br />
but also numerous kinds of bulk<br />
goods, like coal and ores, are loaded<br />
and unloaded at maritime and river<br />
terminals, stored and transferred to<br />
power stations, agricultural and<br />
industrial centres using conveyors,<br />
road and rail transport.<br />
Logistics Depends on the<br />
Infrastructure<br />
The multifarious demands made on<br />
ports and terminals make it essential<br />
to have equally flexible handling systems<br />
and machinery at hand, which<br />
make up a highly individual terminal<br />
infrastructure, depending on its geographical<br />
location and the goods it<br />
handles. These facts make it necessary<br />
to take into account a range of<br />
parameters which will influence the<br />
choice of equipment for the handling<br />
systems. After all, the choice of handling<br />
equipment is generally not a<br />
A <strong>Gottwald</strong> HMK 360 EG<br />

one-off matter. Quite the contrary,<br />
these machines are integral parts of<br />
a complex handling system, which<br />
includes not merely the ship and the<br />
crane but also such ancillary equipment<br />
as hoppers, conveyor belts and<br />
land-based transport vehicles.<br />
At the same time, downstream<br />
elements of the industrial infrastructure,<br />
such as power generators, steel<br />
mills, gravel quarries and fertiliser factories,<br />
play a part as do value-added<br />
terminal services, such as washing,<br />
blending and bagging bulk goods.<br />
<strong>Professional</strong> <strong>Bulk</strong> <strong>Handling</strong><br />
Within a broad scope of equipment<br />
and services, ranging from Mobile<br />
<strong>Harbour</strong> <strong>Cranes</strong> and <strong>Port</strong>al <strong>Harbour</strong><br />
<strong>Cranes</strong> to Wide Span Gantries,<br />
<strong>Gottwald</strong> <strong>Port</strong> Technology provides<br />
Apart from the worldwide<br />
transport of consumer goods<br />
on container ships …<br />
... transporting raw and process materials on<br />
bulk cargo ships is a central mainstay of international trade<br />
optimised solutions specially designed<br />
for professional bulk handling operations,<br />
such as<br />
■ hard coal<br />
■ ores and scrap<br />
■ gravel and sand<br />
■ raw and process materials, such<br />
as fertilisers, sugar and agribulk.<br />
High-performance, economical handling<br />
equipment made and supplied<br />
by <strong>Gottwald</strong> <strong>Port</strong> Technology can<br />
easily be integrated in existing or<br />
future workflows and infrastructures<br />
for professional bulk handling. As<br />
the world’s market leader in the field<br />
of Mobile <strong>Harbour</strong> <strong>Cranes</strong>, <strong>Gottwald</strong><br />
is a byword for extensive know-how<br />
and well-founded experience in<br />
terminal logistics and in designing<br />
efficient bulk handling facilities.
The Sky’s the Limit in <strong>Bulk</strong> <strong>Handling</strong><br />
With <strong>Harbour</strong> <strong>Cranes</strong> from <strong>Gottwald</strong> <strong>Port</strong> Technology<br />
As the world’s prime supplier of<br />
Mobile <strong>Harbour</strong> <strong>Cranes</strong>, <strong>Gottwald</strong><br />
<strong>Port</strong> Technology can offer the full<br />
range of performance products <strong>with</strong><br />
lifting capacities of up to 120 tonnes<br />
and radii of up to 56 m and incorporating<br />
a complete range of four-rope<br />
grab cranes for professional bulk<br />
handling – up to 1,500 tph.<br />
Four-Rope Grab <strong>Cranes</strong><br />
On the back of <strong>Gottwald</strong>’s success<br />
as the world’s key supplier of HMK<br />
Mobile <strong>Harbour</strong> <strong>Cranes</strong> for handling<br />
containers comes the four-rope grab<br />
version, which is becoming a common<br />
feature of multipurpose and bulk<br />
terminals the world over for highperformance<br />
handling.<br />
With a view to maximising the<br />
terminal operators’ benefits, the<br />
series is subject to constant review<br />
and upgrading to cater for current<br />
requirements in terms of lifting<br />
capacity, crane classification and<br />
moves per hour.<br />
Also Available as <strong>Port</strong>al <strong>Harbour</strong><br />
<strong>Cranes</strong><br />
<strong>Gottwald</strong>’s answer to modern<br />
demands for high-performance, railbound<br />
bulk-handling cranes was<br />
the development of the HSK <strong>Port</strong>al<br />
<strong>Harbour</strong> Crane <strong>with</strong> a four-rope grab.<br />
A comprehensive range of HSKs<br />
provide the same benefits as those<br />
offered by four-rope HMK grab<br />
cranes – where the HSK portal is<br />
adapted to suit the specific customer’s<br />
requirements.<br />
Diesel-Electric or Fully Electric<br />
Drive<br />
<strong>Gottwald</strong>’s HMK and HSK cranes are<br />
powered by diesel-electric drive systems.<br />
However, they can be designed<br />
from the outset or subsequently<br />
retrofitted to run on an existing<br />
quay-side electric power supply. In<br />
either case, both the diesel-electric<br />
and external power supply alternatives<br />
provide excellent availability and<br />
optimised economy of use.<br />
<strong>Gottwald</strong> <strong>Harbour</strong> <strong>Cranes</strong> are individually adapted to suit the specific workflows of industries close to the terminal – as here at<br />
SAPEC in <strong>Port</strong>ugal, where the ship, HMK 170 EG Mobile <strong>Harbour</strong> Crane, hopper and conveyor belt form a seamlessly integrated unit<br />

Setting up and expanding quayside<br />
facilities and terminals are long-term,<br />
cost-intensive undertakings influenced<br />
by a number of factors. Of crucial<br />
importance is the choice of the handling<br />
equipment because it is this<br />
aspect that influences the quayside<br />
infrastructure most decisively, as<br />
regards the rail tracks, foundations<br />
and power supply. Depending on<br />
the handling equipment chosen,<br />
savings of up to 15% in infrastructure<br />
overheads are possible. With<br />
existing terminals, it is also essential<br />
to include the track widths, maximum<br />
quay loadings and conveyor<br />
systems in the calculations for the<br />
supply of new handling equipment.<br />
In the case of professional bulk handling,<br />
terminal operators can choose<br />
from a wide range of handling<br />
equipment options. In each specific<br />
case, however, the operator will want<br />
to consider and evaluate all the possible<br />
advantages and disadvantages<br />
of each option. The key factors are<br />
these:<br />
■ the type of bulk goods to be<br />
handled<br />
■ the proportion of total handling<br />
taken up by bulk<br />
■ the required handling performance.<br />
Flexible Solutions <strong>with</strong><br />
Performance Rates of up to<br />
1,500 tph<br />
With its HMK and HSK <strong>Harbour</strong><br />
<strong>Cranes</strong>, <strong>Gottwald</strong> can meet all the<br />
requirements for professional bulk<br />
handling <strong>with</strong> customer-specific<br />
application solutions. Both series are<br />
based on the same proven technology<br />
in use worldwide and are individually<br />
to meet customer-specific requirements<br />
in terms of quayside loadings,<br />
portal dimensions and general local<br />
conditions.<br />
WSG Wide Span Gantry handling coal at the<br />
port in Aschaffenburg, Germany<br />
<strong>Gottwald</strong> manufactures the WSG series of<br />
Wide Span Gantries for the specific requirements<br />
of inland terminals. These cranes are<br />
ideal not merely for loading and unloading<br />
ships but also for intermodal and trimodal<br />
handling between transport modes.<br />
As a four-rope grab crane, the HMKs<br />
and HSKs are designed for highperformance<br />
handling rates of up to<br />
1,500 tph and are, as a result, now<br />
overlapping <strong>with</strong> fields previously<br />
dominated by gantry grab and continuous<br />
ship unloaders. The benefit<br />
to the terminal operator is the comparatively<br />
low investment volume<br />
and the extensive range of benefits<br />
available <strong>with</strong> the crane.<br />
The HSK <strong>Port</strong>al <strong>Harbour</strong> Crane is<br />
always the preferred solution where<br />
an operator is considering replacing a<br />
low-performance double-link luffing<br />
crane which is several decades old.<br />
In these circumstances, <strong>Gottwald</strong><br />
HSK cranes provide numerous advantages<br />
due to their much reduced<br />
dead weight and the more simple<br />
construction of the boom.
The Advantages at a Glance<br />
In view of the high costs of maintaining<br />
a quayside infrastructure,<br />
the need for economical operation<br />
and for flexible, future-orientated<br />
solutions, Mobile <strong>Harbour</strong> Crane<br />
technology made by <strong>Gottwald</strong> is<br />
making significant inroads in the bulk<br />
handling market. Equipped <strong>with</strong> a<br />
wide spectrum of features, <strong>Gottwald</strong><br />
cranes offer numerous advantages,<br />
whether as Mobile HMKs or <strong>Port</strong>al<br />
HSKs, whether as conventional tworope<br />
versions <strong>with</strong> a motor grab or<br />
as four-rope grab versions. These<br />
advantages include:<br />

Four-Rope Grab <strong>Cranes</strong> for<br />
<strong>Professional</strong> <strong>Bulk</strong> <strong>Handling</strong><br />
Success at Full Speed<br />
As a result of their versatility,<br />
<strong>Gottwald</strong> Mobile <strong>Harbour</strong> <strong>Cranes</strong><br />
are the ideal choice for handling all<br />
manner of cargoes. With regard to<br />
the further development of its Mobile<br />
<strong>Harbour</strong> <strong>Cranes</strong>, <strong>Gottwald</strong> has always<br />
placed uncompromising emphasis on<br />
meeting the needs of ever larger ships<br />
and barges and all the other factors<br />
influencing terminal operations, in<br />
order to respond to terminal operators’<br />
requirements for special-purpose<br />
applications and higher tonnages.<br />
The further development of the<br />
Mobile <strong>Harbour</strong> Crane to produce<br />
the four-rope grab crane for professional<br />
bulk handling was a rational<br />
step which, once again, is evidence<br />
of <strong>Gottwald</strong>’s unswerving commitment<br />
to retaining its technological<br />
market-leadership.<br />
The steel constructions were strengthened<br />
to meet the requirements of<br />
higher crane classification, a second<br />
hoist was fitted and, where required,<br />
a second slewing gear is fitted, the<br />
roller bearing slew ring assembly and<br />
Two hoists fitted to a<br />
<strong>Gottwald</strong> four-rope grab crane<br />
the rope pulleys were adapted to<br />
meet the higher demands of tough<br />
bulk handling – modifications and<br />
improvements that make <strong>Gottwald</strong>’s<br />
four-rope grab cranes the preferred<br />
choice.<br />
Four-Rope Grab <strong>Cranes</strong> <strong>with</strong> 30%<br />
Improved Performance over<br />
Motor Grabs<br />
The considerably reduced dead<br />
weight of the four-rope grab coupled<br />
<strong>with</strong> the shorter closing times compared<br />
to motor grabs mean that<br />
<strong>Gottwald</strong>’s four-rope grabs manage<br />
a far better payload per move.<br />
Along <strong>with</strong> higher operating speeds,<br />
the overall handling performance<br />
is dramatically improved and these<br />
cranes can out-perform a two-rope<br />
Mobile <strong>Harbour</strong> Crane <strong>with</strong> a motor<br />
grab by up to 30%.<br />
One additional benefit of the fourrope<br />
grab is its rigidity which makes<br />
it far less susceptible to knocks and<br />
damage when used in tough, nonstop<br />
operation. This results in reduced<br />
maintenance requirements and crane<br />
downtimes are reduced to an absolute<br />
minimum.<br />
Even as a Four-Rope Grab Crane,<br />
its Versatility does not Suffer<br />
Even when constructed as four-rope<br />
grab cranes, <strong>Gottwald</strong> Mobile<br />
<strong>Harbour</strong> <strong>Cranes</strong> do not forfeit the<br />
versatility for which <strong>Gottwald</strong> is<br />
renowned and they are not restricted<br />
to bulk handling. When fitted <strong>with</strong><br />
the numerous lifting devices available,<br />
such as spreaders, equalising<br />
spreader beams and magnets, these<br />
cranes can quickly move containers,<br />
semi-finished goods, pallets and all<br />
manner of project cargoes.<br />

Selection Criteria for <strong>Cranes</strong><br />
The selection of the crane size for<br />
a specific application profile and the<br />
choice between a two-rope and a<br />
four-rope version are determined by<br />
many factors.<br />
Deciding on the Crane Size<br />
Required<br />
The decision as to the size of crane<br />
needed will depend on the maximum<br />
anticipated cargo load and, as regards<br />
the working radius, the width of the<br />
largest vessel to be loaded or<br />
unloaded.<br />
Two-Rope Crane or Four-Rope<br />
Grab Version?<br />
In order to decide whether a two-rope<br />
or four-rope version is most economical,<br />
the following points will need<br />
clarification:<br />
■ the required move speed in<br />
terms of tonnes per hour or<br />
tonnes per year<br />
■ the proportion of total handling<br />
taken up by bulk handling<br />
■ any special requirements resulting<br />
from the type of bulk materials.<br />
Please also refer to the example on<br />

Given these facts, there are two<br />
options available from <strong>Gottwald</strong>:<br />
the HMK 330 EG and the HMK 300 E.<br />
HMK 330 EG – If <strong>Bulk</strong> <strong>Handling</strong><br />
is the Major Application<br />
If the new crane is to be used for<br />
bulk handling for more than 80% of<br />
the time and only handle containers<br />
at peak times, it makes sense to<br />
invest in a four-rope grab crane. This<br />
model will achieve rates of up to<br />
1,200 tph due to far higher payloads<br />
and improved speeds in contrast <strong>with</strong><br />
the motor grab alternative.<br />
HMK 300 E – If Container <strong>Handling</strong><br />
is the Major Operation<br />
If it is the container handling aspect<br />
that is of key importance, the tworope<br />
crane and motor grab option<br />
will provide the more economical<br />
solution because this crane<br />
■ is fully able to deal <strong>with</strong> the<br />
container handling requirements<br />
■ will achieve the required minimum<br />
of 850 tph <strong>with</strong> the motor grab.

Crane Life – A Question of<br />
Crane Classification<br />
The anticipated crane life and the<br />
performance required of the machine<br />
are key criteria determining the<br />
investment in handling equipment.<br />
The lifetime of the crane is determined<br />
by the strength of the steel<br />
construction for a given handling<br />
rate. In order to achieve the lifetime<br />
The HSK series of <strong>Port</strong>al <strong>Harbour</strong><br />
<strong>Cranes</strong>, which use a portal instead of<br />
a rubber-tyred chassis, was developed<br />
specifically <strong>with</strong> operation on narrow<br />
quaysides in mind, and they represent<br />
<strong>Gottwald</strong>’s innovative creativity.<br />
Originally instigated as a result of a<br />
customer’s idea but then consistently<br />
developed to the point where they<br />
stand alongside the HMKs as an<br />
additional product line, these cranes<br />
meet the needs of tough, performance-related<br />
bulk handling.<br />
The portal is designed individually to<br />
take account of any conveyor belts,<br />
train or truck traffic on the site.<br />
Maximum mobility for these cranes,<br />
which are rail-bound in operation, is<br />
provided by retractable travel gear<br />
which allows them to move from<br />
one quay to the next. Stabiliser pads<br />
on the portal also enable them to be<br />
operated on quays <strong>with</strong>out rails.<br />
HSK <strong>Port</strong>al <strong>Harbour</strong> <strong>Cranes</strong> have the<br />
same assemblies as the HMK Mobile<br />
<strong>Harbour</strong> <strong>Cranes</strong> from the slewing<br />
ring upwards. With lifting capacities<br />
of up to 120 t, maximum radii of<br />
56 m and handling rates in four-rope<br />

Versatility is the Top Priority<br />
<strong>Harbour</strong> <strong>Cranes</strong> for Use in Multipurpose Terminals<br />
Besides terminals that specialise in<br />
bulk handling or container handling,<br />
there are numerous maritime and<br />
river ports providing handling services<br />
for all manner of cargoes. It is at<br />
these handling sites in particular that<br />
multiple lifting attachments are in<br />
use for containers, project cargoes<br />
and bulk materials.<br />
<strong>Bulk</strong> <strong>Handling</strong> <strong>with</strong> a Motor Grab<br />
Operators of universal terminals of<br />
this type appreciate machines which<br />
provide economical operation, mobility,<br />
versatility and a high degree of<br />
flexibility in changing the lifting attachments<br />
between jobs.<br />

In this context, <strong>Gottwald</strong>’s Mobile<br />
and <strong>Port</strong>al <strong>Harbour</strong> <strong>Cranes</strong>, built<br />
as conventional two-rope cranes,<br />
are ideally suited to handling a<br />
broad spectrum of goods. Depending<br />
on the type and consistence of the<br />
bulk material, motor grabs such as<br />
scissor grab, dual scoop and orangepeel<br />
grabs are used.<br />

External Power Supply Provides<br />
Improved Efficiency<br />
<strong>Gottwald</strong> <strong>Port</strong> Technology is the only<br />
supplier worldwide of diesel-electric<br />
Mobile <strong>Harbour</strong> <strong>Cranes</strong>, which provides<br />
customers <strong>with</strong> the benefits of<br />
low operating and maintenance costs.<br />
To enable terminal operators to<br />
achieve even greater savings in running<br />
costs, <strong>Gottwald</strong> Mobile <strong>Harbour</strong><br />
<strong>Cranes</strong> can be connected to the<br />
shore power supply and run on this<br />
external source. In this way, the crane<br />
drives are supplied direct <strong>with</strong> electri-<br />
Where the power demands are<br />
very high, for instance when handling<br />

<strong>Gottwald</strong> cranes can be fitted <strong>with</strong><br />
a second cable reel.<br />
cal energy from<br />
the terminal<br />
mains supply.<br />
For the external<br />
power feed, the<br />
crane has to be<br />
equipped <strong>with</strong> a<br />
cable reel and is<br />
then connected to an appropriate<br />
power outlet located in the terminal.

is their wide scope of applications.<br />
They are used not only for loading<br />
and unloading vessels but are ideally<br />
suited to transshipment from one<br />
mode of transport to another. In<br />
detail, their suitabilities are as follows:<br />
■ loading and unloading ships<br />
■ intermodal handling between<br />
rail and road<br />
■ trimodal handling in ports<br />
between ship, freight train and<br />
road truck.<br />
WSGs are also the ideal choice as<br />
dedicated storage cranes for organising<br />
storage yards. These newcomers<br />
to the <strong>Gottwald</strong> family<br />
demonstrate their flexibility best,<br />

Originally used for unloading coal and simultaneously managing the storage yard, …<br />
however, in ports where they are also<br />
used for managing storage areas<br />
close to the quay. It is possible, for<br />
example, in the case of coal terminals<br />
located close to a power station, to<br />
unload the coal from a vessel, store<br />
different types of coal on a yard where<br />
they are blended and fed direct to<br />
the coal hopper.<br />
Customer-Orientated Constructions<br />
Each individual portal is built to meet<br />
the specific requirements of each<br />
customer. Cantilevers of up to 40 m<br />
on the waterside enable all the usual<br />
vessel sizes to be serviced not only in<br />
inland terminals but also at smaller<br />
maritime terminals. In addition, total<br />
spans of 80 m provide maximum<br />
flexibility.

<strong>Handling</strong> <strong>Bulk</strong> Material <strong>with</strong><br />
Motor and Four-Rope Grabs<br />
For bulk handling purposes, <strong>Gottwald</strong><br />
supplies its WSGs <strong>with</strong> motor grabs.<br />
If the WSG is operated in a specialised<br />
bulk terminal, the trolley can be<br />
equipped <strong>with</strong> four-rope grab technology<br />
to maximise bulk handling<br />
performance.<br />
... this WSG is now used for handling<br />
and stacking containers due to a<br />
change in the service requirements<br />
at the Aschaffenburg terminal<br />
A second hoist guarantees maximum<br />
availability of the crane during<br />
motor grab operation<br />
Excellent Availability<br />
WSG Wide Span Gantries are generally<br />
equipped <strong>with</strong> a pair of two-rope<br />
hoists. The broad rope spread reduces<br />
the typical swinging effect known<br />
from handling containers and long<br />
goods.<br />
Where bulk handling only uses a<br />
single hoist, the second, redundant<br />
hoist contributes to excellent crane<br />
availability since, in the event of a<br />
failure of one, there is no effect on<br />
performance.<br />
Many Fields of Application<br />
<strong>Gottwald</strong> WSG Wide Span Gantries<br />
are not restricted to use in bulk<br />
handling terminals. They are, in fact,<br />
ideally suited to handling containers<br />
and a wide range of general cargoes.<br />
Superordinate stock management<br />
systems also enable the cranes to<br />
be seamlessly integrated in complex<br />
logistical workflows.<br />
Mobile <strong>Harbour</strong> <strong>Cranes</strong> at Inland<br />
Terminals<br />
<strong>Gottwald</strong> also offers a range of Mobile<br />
<strong>Harbour</strong> <strong>Cranes</strong> for bulk handling at inland<br />
terminals and smaller maritime terminals.<br />
These are the 20-tonne HMK 60 HG and<br />
the 44-tonne HMK 130 HG – both available<br />
as four-rope grab cranes.<br />

Special-Purpose Equipment<br />
Added Value for <strong>Professional</strong> <strong>Bulk</strong> <strong>Handling</strong><br />
For the experts at <strong>Gottwald</strong>, just<br />
delivering one of many types of<br />
standard crane would simply not<br />
be in keeping <strong>with</strong> the company’s<br />
philosophy. <strong>Gottwald</strong> makes every<br />
effort to adapt its cranes on site<br />
to meet the local conditions by,<br />
for example, fitting dust-protection<br />
systems and grab models designed<br />
specifically for a particular application.<br />

Dust-Protection Systems for<br />
Machines and Equipment<br />
<strong>Handling</strong> bulk materials automatically<br />
involves the creation of large amounts<br />
of dust. These represent not only a<br />
loss of valuable materials but also<br />
a source of potential damage to the<br />
cranes and equipment if fine dust is<br />
allowed to penetrate them and interfere<br />
<strong>with</strong> their operation.<br />
To minimise these effects, <strong>Gottwald</strong><br />
installs both passive and active dustprotection<br />
systems to prevent damage<br />
of this kind.<br />
Where the dust emissions at the<br />
terminal are minimal, a passive<br />
dust-protection system will suffice.<br />
On <strong>Gottwald</strong> cranes, this involves<br />
sealing off the machine room as far<br />
as is practicable. This includes the<br />
simple expedient of ensuring access<br />
to the superstructure through a door.<br />
Active Dust-Protection System for<br />
Improved Safety<br />
Terminals producing a high level of<br />
dust emissions are advised to ensure<br />
their cranes and equipment are well<br />
protected by installing high-performance<br />
dust-protection systems. This<br />
involves fresh air, free of dust, being<br />
sucked in through a pipe at the tip<br />
of the tower before it is passed down<br />
to the machine room through a filter.<br />
This produces a slight overpressure<br />
in the machine room to ensure that<br />
no outside air and no dust can enter<br />
the area.<br />
<strong>Gottwald</strong> will<br />
supply the<br />
right grab for<br />
the application<br />
The Type of <strong>Bulk</strong> Material will<br />
Determine the Type of Grab<br />
Whether a dual scoop, scissor grab<br />
or orange-peel grab is required will<br />
depend on the consistence of the<br />
bulk material, be it coal, ore or<br />
artificial fertiliser, and must also<br />
be matched to the crane.<br />
To achieve maximum performance<br />
and speed from a crane, it is crucial<br />
to consider both the density of the<br />
bulk material and the lifting capacity<br />
of the crane when selecting the size<br />
of grab.<br />
<strong>Gottwald</strong> can provide customers<br />
<strong>with</strong> all available kinds of grabs and<br />
makes a point of assisting customers<br />
<strong>with</strong> the selection of the ideal size<br />
and type combination – especially<br />
where different kinds of bulk are to<br />
be handled.
