AUSGABE ISSUE APRIL 2008<br />

FOREWORD<br />

H<br />

Editorial<br />

Dear reader,<br />

The starting signal has been given: the XWORLD Tour has set off! On 9 March the convoy of Toyota Land<br />

Cruisers left <strong>HANSA</strong>-<strong>FLEX</strong>’s head office in Bremen, accompanied by the escort vehicle. Sporting magnificent<br />

paintwork, these vehicles are equipped for whatever tough offroad adventures they may encounter. This<br />

tour, whose highlight will undoubtedly be the visit to the Olympic Games in Beijing, is not just an amazing<br />

experience for all participants and offroad fans, but also a major event for <strong>HANSA</strong>-<strong>FLEX</strong>. The journey through<br />

two continents signals our international claim to be a hydraulic service-provider and system partner while<br />

underlining the steady growth of the company. We hope that everyone taking part has a good trip and are<br />

already looking forward to reading the interesting reports that will appear in HYDRAULIKPRESSE.<br />

In contrast, one topic that sounds a lot less spectacular is the change in the standards laid down by the<br />

employers’ liability insurance association. But something that is so functional as the new BGR 237 regulation,<br />

which provides rules for the safe usage of hydraulic hose lines and is scheduled to come into force this<br />

summer, has previously been the subject of intensive and often controversial debate on advisory boards and<br />

specialist committees. <strong>HANSA</strong>-<strong>FLEX</strong> is involved in many such working groups as we are aware of our responsibility<br />

for man and the environment and strive to live up to it. With this objective in mind, <strong>HANSA</strong>-<strong>FLEX</strong><br />

training manager Ulrich Hielscher has drawn on his immense knowledge when creating the new practical<br />

guide for the proper handling of hydraulic hose lines. This way we are doing our bit to update standards in<br />

the hydraulics sector. In an interview on page 24 Ulrich Hielscher explains what BGR 237 actually means in<br />

practical terms.<br />

Such engagement in boards and committees forms part of the responsibilities of a system provider for fluid<br />

technology, a role <strong>HANSA</strong>-<strong>FLEX</strong> has meanwhile taken on. It is thus not surprising that Axel Tammen also<br />

has plenty of experience to offer in national and international standardisation committees. Last year this<br />

graduate engineer was appointed by <strong>HANSA</strong>-<strong>FLEX</strong> to the new position of “General Manager Technology”,<br />

a role which in his view consists of acting as the go-between for technology and sales - including for our<br />

customers. On page 26 of this issue he tell readers how he wants to ensure that the Technical Department<br />

is involved more closely in the overall development of the company and why this will help to improve customer<br />

satisfaction.<br />

XWORLD: Starting signal for a world of adventure<br />

Get on board and the fun will start<br />

cope with anything. The level of comfort offered by<br />

these cars makes driving even more enjoyable.<br />

Round the world four times<br />

At eleven o‘clock on 9 March 2008 the time had come:<br />

the procession of vehicles taking part in the XWORLD<br />

Tour pulled away from the starting line. The convoy<br />

of five brightly decorated Toyota Land Cruisers and<br />

the Toyota Hilux escort car set off with their crews for<br />

Istanbul from the yard of <strong>HANSA</strong>-<strong>FLEX</strong>‘s HQ.<br />

The participants were seen off at the head quarter<br />

of the <strong>HANSA</strong>-<strong>FLEX</strong> Group in Bremen by managing<br />

directors Uwe Buschmann and Diether Horst<br />

Seidler, who wished them lots of enjoyment on<br />

their exciting trip. “We see the XWORLD Tour as<br />

a good opportunity to present <strong>HANSA</strong>-<strong>FLEX</strong> as a<br />

company with an international flavour to it,” says<br />

Uwe Buschmann, once again underlining the motivation<br />

behind this adventure. “With the XWORLD<br />

Tour we want to bring people together, to promote<br />

understanding between them and to learn about<br />

other cultures. This is why we will also be stopping<br />

at <strong>HANSA</strong>-<strong>FLEX</strong> branches along the route on the different<br />

stages of the tour. Meeting the staff based<br />

there will offer particularly clear insights of how<br />

people live in the region visited.”<br />

Months before setting off, the expedition vehicles<br />

underwent tough testing to check their suitability<br />

for the tour: the Land Cruisers have been out and<br />

about on Europe’s roads since the spring of last year.<br />

The vehicles are fitted out with all conceivable extras<br />

and special offroad equipment such as snorkels<br />

for driving through rivers, search headlights and a<br />

cable winch. They have been customised in this way<br />

to offer participants maximum safety both on- and<br />

offroad while still enjoying the trip. In the months<br />

of preparation leading up to the tour, offroad<br />

fans were offered the opportunity to put the cars<br />

through their paces, as well as customers and employees<br />

of <strong>HANSA</strong>-<strong>FLEX</strong> and journalists from trade<br />

magazines. Their verdict was unanimous: Land<br />

Cruisers are great to drive on motorways and ordinary<br />

roads, but offroad they really come into their<br />

own. Whether faced with mud, steep terrain, roads<br />

full of potholes or river crossings, these vehicles can<br />

Besides the adventure of passing through 34<br />

countries on two continents, pleasure in driving<br />

also plays a key role. In 20 months participants<br />

will cover some 150,000 kilometres in 43 stages,<br />

a distance that is equivalent to four times round<br />

the earth! The longest stage, estimated to be 5,000<br />

kilometres, extends from Kashgar to Beijing and<br />

even the shortest, from Lhasa – the city of the Dalai<br />

Lama – to Kathmandu, is 1,300 kilometres. The trip<br />

takes in the sacred sites of Asia, Lake Manasarova<br />

and Mount Kailash. These two Buddhist sanctuaries<br />

are not normally accessible to tourists but XWORLD<br />

has been given permission to admire them.<br />

In their offroad vehicles participants will be passing<br />

through spectacular sites and fascinating landscapes.<br />

Every one of these stages represents an<br />

expedition with its own extraordinary route.<br />

Right at the start of the tour there is a very special<br />

offroad trip: On the first stage of the route, Bremen<br />

to Istanbul in 14 days, participants have to cross<br />

eight countries, driving right through the varied<br />

Balkan landscape, where they certainly won’t miss<br />

out on any fun. Every further stage has its own particular<br />

charms: Crossing the Carpathians towards<br />

H<br />

Ukraine, Russia and China promises to be no less<br />

fascinating than the eleventh stage, the highlight<br />

of the adventure tour. This special section of the trip<br />

runs along the Great Wall of China, past the Buddhist<br />

cave temples of Yungang towards Beijing,<br />

where the programme includes a visit to the Olympic<br />

Games. Motorsport fans should not miss out on<br />

the 16th stage under any circumstances. After passing<br />

the Yangtze, Asia’s longest river, the convoy will<br />

arrive in Shanghai in time to witness the starting<br />

signal for the Formula 1 race. Stages 29 to 32 take<br />

participants over the mountain passes of the Himalayas<br />

to the base camp of Mount Everest.<br />

Stages 36 to 40 also promise to be an exciting experience,<br />

with all the variety the Russian landscape<br />

has to offer: the vast expanse of Siberia, home to<br />

the Russian Pacific Fleet in Vladivostok, contrasting<br />

with the big cities of Moscow and St Petersburg.<br />

Special delights, individual highlights and unforgettable<br />

moments – the different stages of the<br />

XWORLD Tour take in destinations that cannot be<br />

found in any other travel brochure. You can still sign<br />

Offroad or the more comfortable option?<br />

On the first stage of the XWORLD Tour Melina<br />

Lindenblatt and Matthias Göttenauer will be on<br />

board the escort vehicle as tour guides. The MD<br />

of the agency Pro+Motion responsible for organising<br />

the XWORLD event has many years of<br />

experience in such adventure tours. He also has<br />

a particular interest in the tourist destination of<br />

Istanbul, where the participants will arrive at<br />

the end of the first stage.<br />

Melina Lindenblatt has carefully planned all<br />

stages, even visiting China and Tibet herself to<br />

check the details of the trip and make the accommodation<br />

arrangements. But it is not possible<br />

to prepare for everything as “part of the<br />

fun on such trips is spontaneity,” comments<br />

Matthias Göttenauer. He has already experienced<br />

this himself and therefore also hopes<br />

that the participants in the XWORLD adventure<br />

tour will contribute their ideas and wishes over<br />

the different stages.<br />

The three people in the escort vehicle – Enrico<br />

Kieschnick will also be on board as<br />

<strong>HANSA</strong>-<strong>FLEX</strong>’s XWORLD Tour project manager<br />

during the first stage – want to see together<br />

whether the programme they have put together<br />

appeals to the entrants or whether<br />

changes will result in even greater enjoyment.<br />

For example, in terms of greater pleasure in<br />

driving: Should the percentage of offroad driving<br />

be stepped up? Are the different stages<br />

not too long for participants? And how does<br />

the vehicle equipment stand up during the<br />

tour? The three members of the escort team<br />

are hoping for answers to all these questions<br />

during the first stage, for as Enrico Kieschnick<br />

remarks, “we have put together a great package<br />

for offroad fans”. “The cars have already<br />

shown what they can do under tough test<br />

conditions. Entrants who take a more cautious<br />

approach will have no less fun and adventure<br />

than awaits the more sporty drivers taking the<br />

offroad routes.”<br />

According to Matthias Göttenauer “Participants<br />

can decide later on in the individual stages<br />

whether the next day for example they prefer<br />

to use more offroad routes or proper roads.”<br />

Even breaking down will hold no fears for<br />

entrants: if they are not able to cope with the<br />

problem themselves, the convoy can rely on<br />

Toyota’s round-the-clock service from its dense<br />

network of garages round the world.<br />

PHOENIX CONTACT<br />

One connector – one programme<br />

The best connections in Blomberg<br />

“A high level of vertical integration is our philosophy,”<br />

was the comment from Phoenix Contact, which<br />

added, “We therefore not only develop modern<br />

electronic applications but also use them ourselves<br />

in production.” One example of this is the optimisation<br />

of injection moulding machines designed to<br />

turn plastic parts into finished components ready<br />

for installation or destined for upgrading. Here it is<br />

a question of how to improve the control and processes<br />

of such machines to make them work even<br />

faster. The engineers from Phoenix Contact pass on<br />

such knowledge to their customers and continuously<br />

implement measures for retrofitting. Phoenix<br />

Contact sees itself as a service-provider which sells<br />

its concepts to third parties such as the car manufacturing<br />

industry, where individual automotive parts<br />

are moulded within seconds and then dispatched<br />

to the next station for further processing. Acting<br />

as a system partner for logistics and automation,<br />

Phoenix Contact has been highly successful in this<br />

sector and helps customers with development from<br />

the initial idea to application.<br />

Sure to be reliable<br />

It all started in 1928 with a modular terminal block<br />

that quickly established itself as the standard for<br />

power stations, industrial plants and buildings. Today,<br />

exactly 80 years later, Phoenix Contact offers a<br />

portfolio of industrial electrical products that range<br />

from the classical terminal block through machine<br />

connectors, electronic signal converters and surge<br />

protection to wireless Ethernet and industrial automation<br />

technology. This global player recently broke<br />

through the 1 billion euro sales mark.<br />

The company based in Blomberg uses four production<br />

plants in Germany and five international<br />

facilities to manufacture connecting elements<br />

such as PCBs and connectors for modern electronic<br />

engineering applications, so ensuring the best connections<br />

from sensors to control thanks to prefabricated<br />

modules. Such plug connections are used<br />

for example in the field of traffic engineering, the<br />

automotive industry, shipbuilding and mechanical<br />

engineering, for industrial communication in<br />

process technology and of course, as the standard<br />

in power plants. The standard of the green connector<br />

from Phoenix Contact ensures maximum operational<br />

safety whatever the sector. Phoenix Contact<br />

manufactures all connectors, plug connections,<br />

PCBs and terminal blocks in-house, using plastic<br />

materials together with injection moulding machines<br />

designed according to its own concepts.<br />

The injection moulding machines used by Phoenix<br />

Contact are subject to heavy workloads and operate<br />

virtually non-stop. Here high locking pressures of<br />

25 – 150 t ensure perfect functioning of these machines,<br />

so allowing them to produce precision parts<br />

of exactly the right shape. The tools used in such<br />

a machine open and close in a fast cycle, with the<br />

necessary flexibility being provided by hydraulic<br />

hose lines. In addition, the injection moulding tools<br />

are exposed to temperatures ranging from 60 – 200<br />

degrees C in the factory environment.<br />

In this context Phoenix Contact sets great store by<br />

operational reliability. It counts on <strong>HANSA</strong>-<strong>FLEX</strong><br />

to rule out the failure of hydraulic hose lines and<br />

so prevent any loss of production. The hydraulic<br />

service-provider has supported the manufacturer<br />

in Blomberg for 20 years, initially from Boffzen until<br />

the company decided to look after this customer<br />

with the branch at Blomberg. As Phoenix Contact’s<br />

production plant is within sight from this branch,<br />

the company is always on hand to quickly respond<br />

to the customer’s needs at any time. When it comes<br />

to routine business such as mechanical engineering,<br />

<strong>HANSA</strong>-<strong>FLEX</strong> supplies the customer with hose<br />

lines, couplings, hydraulic precision piping and a<br />

H<br />

personal advice service - a task which has been the<br />

responsibility of Vinzenz König for ten years.<br />

When injection moulding machines are involved,<br />

<strong>HANSA</strong>-<strong>FLEX</strong> can be relied on to ensure their operational<br />

readiness. By performing regular maintenance,<br />

it contributes not only to safety at the<br />

plant, but also staff safety. Phoenix Contact takes<br />

the precaution of replacing all hydraulic lines on<br />

machinery every six years, so complying with the<br />

recommendations of the employers’ liability insurance<br />

associations, insurance companies and classification<br />

societies. This means that it is protected<br />

from any rights of recourse.<br />

Fast fitting depends on careful<br />

preparation<br />

Vinzenz König teams up with Oliver Beckmann,<br />

head of technical maintenance and servicing at<br />

Phoenix Contact, to coordinate this work. Planning<br />

starts three or so months before execution to avoid<br />

any unnecessary downtimes for the production<br />

machinery. The “man from <strong>HANSA</strong>-<strong>FLEX</strong>” determines<br />

the exact requirements for hose material,<br />

fittings and screwed connections in advance so that<br />

the <strong>HANSA</strong>-<strong>FLEX</strong> mobile service centre can turn up<br />

later on with all necessary spares already on board.<br />

The service technicians manning the workshop on<br />

wheels manufacture the new hose lines according<br />

to samples and install them to produce a perfect<br />

fit.<br />

Such work also includes dismantling machine<br />

panelling and injection moulding units so the old<br />

hose lines can be removed. New ones are then<br />

manufactured according to samples and installed<br />

on the machinery. The first trial run is attended by<br />

a <strong>HANSA</strong>-<strong>FLEX</strong> service technician. The final step is<br />

to put the injection moulding machine back into<br />

production.<br />

<strong>HANSA</strong>-<strong>FLEX</strong> additionally provides the customer<br />

with PTFE corrugated hoses; only recently were 15<br />

machines retrofitted with such hoses. These PTFE<br />

hoses are subject to a temperature control cycle at<br />

approx. 200 degrees C. In this cycle the hoses transport<br />

the medium used for temperature control of<br />

the injection moulding tools in the machines.<br />

Like many other <strong>HANSA</strong>-<strong>FLEX</strong> customers, Phoenix<br />

Contact also has all new hydraulic hose lines it installs<br />

immediately marked with an X-CODE. As the<br />

data for every machine is registered by <strong>HANSA</strong>-<strong>FLEX</strong>,<br />

spare parts can be replaced quickly and easily with<br />

the help of the X-CODE. This also greatly facilitates<br />

job planning for the regular replacement of hose<br />

lines every six years as <strong>HANSA</strong>-<strong>FLEX</strong> can find out<br />

beforehand which spares are required with a click<br />

of the mouse. They can then be manufactured in<br />

advance, so significantly reducing the fitting times<br />

on site. A cost advantage that is systematically exploited<br />

by Phoenix Contact.<br />

MAN DIESEL<br />

Fired up about heavy diesel<br />

Precision work at 1350 degrees<br />

Anton Schweyer plunges the temperature sensor<br />

deep into the enormous foundry ladle. The thermometer<br />

reads 1350 degrees C for the metallic lava<br />

bubbling inside. The foundry expert is satisfied. He<br />

indicates his approval with a quick glance at his colleagues<br />

at the other three ladles and then gives the<br />

signal for casting.<br />

At the touch of a button the weighty containers tip<br />

forward simultaneously, pouring the red-hot metal<br />

into the casting mould with amazing accuracy.<br />

There’s no going back. The next 100 seconds will<br />

decide the quality of the crankcase produced from<br />

this fiery liquid.<br />

Every week an average of four large crankcases<br />

are produced at the foundry of MAN Diesel. These<br />

gigantic workpieces weighing many tonnes are<br />

the heart of the diesel engines manufactured at<br />

the company’s HQ in Augsburg. The biggest case<br />

for the 18V48/60 weighs in at 90 t, with 115 t of<br />

metal being melted for the casting process. Engines<br />

of this type deliver an output of 29,300 hp (21,600<br />

kW) and are used to drive tankers, container ships,<br />

cruise liners and power stations.<br />

Casting seems a very archaic process to the layman.<br />

It actually involves a very high level of precision<br />

work, calling for years of experience, an instinctive<br />

feel and team spirit, explains Jochen Wyrtki,<br />

who has managed the foundry at Augsburg for<br />

three years: “The big castings are worth as much<br />

as 130,000 euros, so nothing must wrong. In addition,<br />

it would take weeks until we’d be able to<br />

supply a replacement. With the high workload of<br />

our production plant, that would be a fiasco. This is<br />

why we check every machine and piece of equipment<br />

before each casting process. Casting not only<br />

involves the foundry men but also mechanics and<br />

electricians to make sure we are equipped to deal<br />

with any problems.”<br />

At the foundry things generally hot up above all at<br />

night. A total 20 MW of energy is available to the<br />

Augsburg works of MAN Diesel. The foundry needs<br />

up to 10 MW of electricity for melting the metal.<br />

The only solution here is to work at night, when the<br />

workload at the other parts of the plant are lower<br />

and the greatest reserves of energy are available.<br />

The smelting process for the biggest engine block<br />

takes about eleven hours. Initial preparations start<br />

at around 5 pm, while casting generally takes place<br />

in the small hours from four o’clock onwards. v<br />

Not just for MAN<br />

Besides crankcases, the foundry also produces cylinder<br />

heads, flywheels, supporting rings and crankshaft<br />

bearing caps for the company’s own diesel<br />

engines as well as components for turbochargers,<br />

which are also manufactured at Augsburg. But the<br />

firm also receives contracts from external customers.<br />

For example, the wind energy industry has rotor<br />

hubs and machine supports for wind turbines<br />

manufactured by MAN Diesel, while its affiliate<br />

RENK orders gearbox parts, and machine tool manufacturers<br />

buy machine beds made at Augsburg. For<br />

Jochen Wyrtki such external orders are important:<br />

“Job castings confront us with new technological<br />

challenges. If we only worked for MAN Diesel, the<br />

company could not develop further. This simultane-<br />

8<br />

ISSUE APRIL 2008


MAN DIESEL<br />

H<br />

ously allows us to check whether our prices are in<br />

line with the market. We must of course make sure<br />

that external orders do not deprive us of the capacity<br />

to cover our own requirements.”<br />

Unlike in the steel trade, the raw materials for the<br />

foundry are available in sufficient quantities on the<br />

international market. The company mainly uses<br />

pig iron and two different qualities of steel scrap<br />

which has been recycled. It procures pig iron from<br />

countries such as South Africa, South America and<br />

<strong>Canada</strong>. Its relationship with these suppliers is of<br />

key importance to ensure that the raw materials<br />

are of uniform quality. “We cannot use scrap from<br />

cars as this metal is too highly finished by the automotive<br />

industry. The various coatings are entirely<br />

unsuitable for casting. We mainly use waste produced<br />

during flame cutting and when dismantling<br />

steel structures, for example halls or rail track. The<br />

household appliance industry also provides very<br />

good raw materials in the shape of refrigerators,<br />

ovens and washing machines,” remarks Jochen<br />

Wyrtki.<br />

With a final shower of sparks the flow of metal<br />

slowly peters out from the ladles, with the last<br />

drops gleaming as they fall into the mould. Anton<br />

Schweyer and his team move back the containers to<br />

their original position. 17 days later they will know<br />

whether casting was successful. This is the time the<br />

crankcase has to remain in a pit to cool down before<br />

it can take centre stage in a new engine.<br />

Moulded by hand<br />

250 workers are employed at the foundry at Augsburg,<br />

and everyone of them is fired up about their<br />

profession. Many have been at MAN Diesel for over<br />

25 years and completed their apprenticeship at the<br />

company. “Most people think this is a bone-breaking<br />

business, something that’s not true at all. The<br />

heavy parts are always transported by crane, so that<br />

you don’t have to be a bodybuilder to work here.<br />

For me the particular fascination is having the result<br />

of your own work appear before your very eyes<br />

- in other words, the finished casting. The moulds<br />

for cast parts are made of plain pit sand, to which<br />

resin and hardener have been added. All moulds<br />

are handmade as MAN Diesel’s foundry is one of the<br />

five biggest handmoulding plants in Germany. The<br />

moulder generally makes his mould himself - years<br />

later he will still be able to say in which engine his<br />

casting was installed.<br />

For moving moments<br />

Line engineering for big marine diesel<br />

Ships‘ engines that are as tall as a house – true hightech<br />

equipment – it is here that <strong>HANSA</strong>-<strong>FLEX</strong> acts as<br />

a partner and OEM to MAN in the field of fluid line<br />

engineering.<br />

The two-stroke diesel engines, which operate at<br />

between 75 and 250 rpm, have an output of 97,000<br />

kW at the propeller and are used in big cargo ships.<br />

MAN Diesel‘s 4-stroke engines are manufactured as<br />

medium and high-speed engines. While 2-stroke<br />

engines are mainly used for merchant shipping,<br />

4-stroke engines are installed in passenger liners<br />

and special ships such as tugs or cable-laying ships.<br />

Fast little 4-stroke engines are also a popular choice<br />

for high-speed ferries.<br />

When it comes to developing new engines, Reinhard<br />

Thoms, the member of staff responsible for<br />

the design of hose lines for marine engines at MAN,<br />

can count on the advice and support of Michael Eggers<br />

from <strong>HANSA</strong>-<strong>FLEX</strong>‘s Hamburg branch. At this<br />

early design stage they work out what exactly is<br />

feasible to avoid subsequent cost traps and develop<br />

solutions which are up-to-date not only in terms of<br />

technology but also layout. Development times at<br />

MAN are greatly shortened by <strong>HANSA</strong>-<strong>FLEX</strong>‘s ability<br />

to promptly supply prototype samples for testing.<br />

Paying close attention to the manufacturer’s specifications<br />

and engineering drawings, <strong>HANSA</strong>-<strong>FLEX</strong><br />

produces connecting elements ready for installation<br />

for the fluid technology of the marine engine. And<br />

not just for the lube oil and coolant pipes but also<br />

the air lines for the starting air, as well as the heavy<br />

oil and fuel oil, used to improve the flow characteristics<br />

of the heavy oil. PTFE hoses, which have been<br />

But with cream please!<br />

Expert filling for a versatile range<br />

Three feed lines are required if chocolate pudding is<br />

to be swirled with vanilla pudding and then topped<br />

with cream. The heads of the filling machine accompany<br />

the containers on the conveyor belt and<br />

distribute the exact quantity of product required<br />

into each container via flexible PTFE corrugated<br />

hoses. In an unflagging one-second rhythm the<br />

hoses are moved along in step with the containers<br />

and then returned to their home position. One<br />

glance at the transparent hoses is all it takes for the<br />

plant foreman to tell whether it is cream, chocolate<br />

pudding, fruit yoghurt or vanilla sauce that is currently<br />

coursing through the pipes. This means he<br />

always has full control of the system to ensure a<br />

smooth product supply. One filling system can handle<br />

28,000 containers per hour, generally operating<br />

in a cycle of 36 hours. The machine is then cleaned<br />

automatically and switched over to a new product.<br />

Chocolate pudding topped with cream, red jelly with<br />

vanilla sauce, yoghurt with exotic fruit or milk pudding<br />

with a swirl of chocolate. Sweet desserts and<br />

speciality yoghurts from Campina are what foodies<br />

reach for throughout the day. A tasty snack, with hygienic<br />

packaging.<br />

Campina at Gütersloh produces a whole range of<br />

dairy products. The raw material here is milk. It can<br />

be processed as plain milk for drinking, mixed milk<br />

drinks, yoghurts and desserts as well as products<br />

made of cheese, butter and cream. The company<br />

regularly adds new specialities to its range: yoghurt<br />

with stracciatella, multi-flavoured “swirled”<br />

desserts, rice pudding with cherries with small<br />

portions in divided containers, which are filled<br />

separately. This international dairy producer never<br />

stops thinking up new ideas for the retail sector to<br />

make sure consumers are met with a wide selection<br />

of products in the chilled cabinet.<br />

This often involves quickly switching between<br />

products at the factory, something that is of course<br />

only possible with sophisticated process technology<br />

and high logistical efficiency. Tankers containing<br />

fresh milk for the dairy products constantly roll up<br />

at Gütersloh. Other deliveries include ingredients<br />

such as fruit pulp, processed fruit, chocolate chips,<br />

cream or sweet woodruff, as well as containers of all<br />

shapes and sizes, already equipped with labels for<br />

the different brands. There are of course also boxes,<br />

which are then put together as crates on pallets<br />

for shipment. Every day between 1,200 and 1,500<br />

pallets leave the factory laden with their delicious<br />

cargo, ready for distribution throughout Europe.<br />

Blended in the container<br />

Anyone walking through the production plant<br />

will be struck by the confusion of pipes containing<br />

brown, red or white liquids: chocolate pudding,<br />

fruit sauce or cream, which is conveyed via the filling<br />

system from the storage tanks to the containers<br />

standing ready. A sophisticated system of hose lines<br />

brings together the different ingredients in the filling<br />

machine and then blends them in the container.<br />

Line engineering plays a key role at the company.<br />

Things are of course rather tight at the filling machines.<br />

To fill a crate with twelve 500 gr containers<br />

for example, the feed lines for the ingredients<br />

have to be connected to the relevant filling heads.<br />

Special pipes were once used for this purpose. This<br />

resulted in awkward situations as they sometimes<br />

had to be bent into complicated shapes to fit into<br />

the confined space available. Great accuracy was<br />

required to compensate for the slight deformation<br />

involved. Fast and flexible changeover of the production<br />

machinery was difficult due to the timeconsuming<br />

process necessary here.<br />

The solution: PTFE<br />

Rainer Kahmann, the manager of the technical<br />

warehouse at Campina and Christian Koschorreck,<br />

responsible for engineering at Campina, consulted<br />

Mehmet Susever, MD of nautical elements. For 17<br />

years he has assisted Campina with process technology<br />

at the plant in the role of an external serviceprovider.<br />

All three started looking for alternative<br />

solutions and came across <strong>HANSA</strong>-<strong>FLEX</strong> Boffzen,<br />

the specialists for metal and PTFE hoses. Such hoses<br />

were absolutely ideal for Campina’s requirements.<br />

They joined forces to come up with the very best so-<br />

lutions – so immediately presenting the specialists<br />

from Boffzen with an enormous challenge.<br />

“But <strong>HANSA</strong>-<strong>FLEX</strong> proved to be very patient and<br />

always responded quickly,” said Mehmet Susever,<br />

who is still delighted about their cooperation. “And<br />

even at the weekend we didn’t hesitate to commission<br />

<strong>HANSA</strong>-<strong>FLEX</strong> with the production of hoses. As<br />

the plant works non-stop, this meant we had to<br />

make use of the tight time slots available when<br />

the machines were being cleaned and prepared<br />

for new campaigns.” The specialists in Boffzen have<br />

proved themselves to be committed partners to<br />

Campina, something that has remained unchanged<br />

today. “<strong>HANSA</strong>-<strong>FLEX</strong> is always at the end of the supply<br />

chain in terms of process technology - in other<br />

words, we can only determine the exact measurements<br />

for the PTFE hoses once a process line has<br />

been converted,” remarked Mehmet Susever. “But<br />

very fast delivery is then required. We order the<br />

hoses by phone, and they’re available just a few<br />

hours later.”<br />

One by one the connecting pipes to the filling heads<br />

have now been replaced by transparent PTFE corrugated<br />

hoses, which are ideal for areas with high<br />

hygiene requirements. They have the advantage<br />

of being not only temperature-resistant but also<br />

odourless and tasteless - in other words, safe for<br />

use with foods. Compared with conventional industrial<br />

hoses, they greatly improve product quality,<br />

are easy to maintain and provide for CIP (cleaningin-place)<br />

processes. In addition, PTFE hoses do not<br />

include metal parts. This is important for product<br />

safety: no metal particles can get into the containers.<br />

One special advantage of PTFE hoses is of course<br />

their flexibility, which caters for minor variations in<br />

dimensions. They offer the necessary flexibility so<br />

that at filling plants, the feed lines can be quickly<br />

connected to the filling heads. Campina can thus<br />

achieve a significant reduction in set-up times and<br />

process costs.<br />

At a plant that continuously manufactures fresh<br />

dairy products unscheduled downtimes should<br />

never last very long. This is why Rainer Kahmann,<br />

as the manager of the technical warehouse, has<br />

localised all key spare parts and keeps sufficient<br />

stocks of these components. <strong>Inc</strong>luding of course a<br />

small supply of PTFE hose lines, articles which really<br />

only become unusable due to improper handling or<br />

mechanical influences. To avoid such influences<br />

Campina also uses PTFE hoses in areas where filling<br />

does not take place. These hoses feature a metal<br />

braid jacket or are protected from abrasion through<br />

contact with the ground by double metal spirals<br />

<strong>HANSA</strong>-<strong>FLEX</strong> Thailand<br />

Sights set on expansion<br />

<strong>HANSA</strong>-<strong>FLEX</strong> Hydraulic Thailand can trace its<br />

origins back to 2003, when the beginnings of a<br />

small-scale business relationship were marked by a<br />

visit to the <strong>HANSA</strong>-<strong>FLEX</strong> head office in Bremen and to<br />

<strong>HANSA</strong>-<strong>FLEX</strong> Metal Hoses in Boffzen by Kitisak Suwanwong,<br />

Amporn Khanarsa and Yanyong Homsrivaranon.<br />

That visit developed into a partnership<br />

which still endures today, and which led in mid 2006<br />

to the establishment of a branch office in Bangkok,<br />

the political, economic and cultural center of the<br />

country.<br />

At the time, <strong>HANSA</strong>-<strong>FLEX</strong> was suddenly attempting<br />

to establish itself as a new brand name on a<br />

hydraulics market which was already able to offer<br />

a wide variety of products from all over the world<br />

at any time, with competitors who had been operating<br />

in the sector for 30 years. Nevertheless, the<br />

Thai managers invested all their efforts in ensuring<br />

that the <strong>HANSA</strong>-<strong>FLEX</strong> name quickly became known<br />

among the customer base.<br />

The reasons their efforts were so successful lay<br />

primarily in the high-quality, in-demand products<br />

the company offered and in an extraordinarily<br />

high level of service. That standard of service was<br />

experienced at first hand by Enrico Kieschnick from<br />

the Bremen head office on a recent visit. “The local<br />

colleagues are highly committed, and they have<br />

plenty of plans for the future,” he reported.<br />

Nowadays <strong>HANSA</strong>-<strong>FLEX</strong> Thailand operates two<br />

branches in Bangkok, with its population of 11.5<br />

million people, and one other in Saraburi province.<br />

The company is now not only able to supply its customers<br />

with the complete range of hydraulic hoses,<br />

metal and PTFE hoses and corrugated hoses, it also<br />

fabricates pipelines, special pipes and fittings. The<br />

fittings are designed to customer specification, so<br />

they can be fitted in any application and in any position.<br />

The special pipes and fittings manufacturing<br />

facility is located at the second Bangkok branch in<br />

Chaokhuntaharn. With a team of in-house engineers,<br />

<strong>HANSA</strong>-<strong>FLEX</strong> Thailand provides customers<br />

with an on-site installation service. Kitisak Suwanwong<br />

and his staffs receive intensive support and<br />

assistance in their work from the Bremen head office<br />

and from the metal hose specialists in Boffzen.<br />

Frank Schmidt, export manager of <strong>HANSA</strong>-<strong>FLEX</strong><br />

GmbH, and his team are particularly focussed on<br />

supporting and encouraging their colleagues in<br />

Thailand wherever and whenever possible.<br />

Customers and plans<br />

One of <strong>HANSA</strong>-<strong>FLEX</strong> Thailand’s key customer accounts<br />

is the Siam Cement Group, the largest<br />

industrial conglomerate in the country with over<br />

100 separate business units operating in industries<br />

including chemicals, paper and construction materials,<br />

as well as cement of course. The company’s<br />

mighty excavators and concrete mixers are fitted<br />

with hydraulic hoses from <strong>HANSA</strong>-<strong>FLEX</strong> Thailand.<br />

The service package also includes on-site fitting<br />

to vehicles and equipment by <strong>HANSA</strong>-<strong>FLEX</strong> technicians.<br />

The local managers in Thailand are considering<br />

introducing <strong>FLEX</strong>XPRESS to handle these service<br />

operations. Other key accounts include transformer<br />

manufacturers and the Bangkok Metro transport<br />

company, as well as numerous industrial concerns<br />

from the region. Since mid 2006 the sales of<br />

<strong>HANSA</strong>-<strong>FLEX</strong> Thailand have been steadily rising. The<br />

potential is certainly high, since industry accounts<br />

for some 45 percent of the country’s gross domestic<br />

product.<br />

The figures speak for themselves. In 2007, metal<br />

hoses and special pipes accounted for 75 percent<br />

of <strong>HANSA</strong>-<strong>FLEX</strong> Thailand’s total sales; 18 percent<br />

were hydraulic hoses; and seven percent were other<br />

components. Expansion is very much on the cards in<br />

future. In order to achieve long-term success, local<br />

managers Kitisak Suwanwong and his colleagues<br />

are looking to adopt the highly promising network<br />

system and, backed by <strong>HANSA</strong>-<strong>FLEX</strong> head office, to<br />

offer their customers a level of service which will<br />

establish the <strong>HANSA</strong>-<strong>FLEX</strong> name firmly on the Thai<br />

hydraulics market.<br />

Augsburg branch: the concept artists<br />

Quick start with OilQuick<br />

The close interlinking of all <strong>HANSA</strong>-<strong>FLEX</strong> branches<br />

and the use of X-CODE also played a role in the decision<br />

in favour of <strong>HANSA</strong>-<strong>FLEX</strong>. As all hose connectors<br />

are supplied with X-CODE as standard, replacement<br />

hoses can easily be obtained from the nearest<br />

<strong>HANSA</strong>-<strong>FLEX</strong> branch. On building sites, <strong>FLEX</strong>XPRESS<br />

also provides on-site assistance. Hence the cooperation<br />

between OilQuick and the colleagues in<br />

Augsburg has a beneficial effect on all branches in<br />

the region of the Federal Republic of Germany. In<br />

addition, the OilQuick fitters can turn to the nearest<br />

<strong>HANSA</strong>-<strong>FLEX</strong> branch if they urgently require components<br />

when fitting a quick-change system for<br />

their customer. They can easily obtain all replacement<br />

components on a delivery note, as in an outline<br />

agreement, OilQuick has negotiated conditions<br />

with <strong>HANSA</strong>-<strong>FLEX</strong>, which are valid in all branches.<br />

OilQuick therefore minimises the effort for procurement<br />

and has a guarantee that the quality of the<br />

components remains the same.<br />

Herbert Wintersteiger (<strong>FLEX</strong>XPRESS), Wolfgang Raunft (workshop/stock), Thomas Karg (branch manager),<br />

Horst Heinrich (workshop/stock)<br />

With the recently opened branch in Augsburg,<br />

<strong>HANSA</strong>- <strong>FLEX</strong> has increased the density of its service<br />

network in one of the most important economic regions<br />

in Bavaria. Everything began with a quick start.<br />

Although the branch only opened in November 2007,<br />

branch manager Thomas Karg, who has 15 years of<br />

experience in hydraulics, developed a concept for the<br />

cooperation with OilQuick Deutschland GmbH. The<br />

result is a classic example of cross-sector cooperation<br />

between <strong>HANSA</strong>-<strong>FLEX</strong> and its customers.<br />

OilQuick manufactures and distributes quickchange<br />

systems for attachments to building machinery.<br />

Within seconds the machine operator can<br />

exchange the tools on his excavator, wheel loader,<br />

or fork-lift truck, regardless of their size or make,<br />

without leaving the driving seat. The system automatically<br />

connects all the hydraulic hoses of the<br />

attachments. This saves time, and as is well known,<br />

time is money.<br />

As OilQuick supplies quick-change systems for all<br />

leading makes of hydraulic machinery throughout<br />

the world, Franz Schauer, the manager of the<br />

German OilQuick agency decided on a cooperation<br />

with <strong>HANSA</strong>-<strong>FLEX</strong>. At a stroke, the company<br />

therefore ensured the support and expertise of the<br />

<strong>HANSA</strong>-<strong>FLEX</strong> Group for the continuously increasing<br />

network of branches and mobile workshops. This<br />

is a service, which no other hydraulic supplier can<br />

provide.<br />

OilQuick is using this advantage to extend and<br />

reinforce its market position. The OilQuick design<br />

department adapts its quick-change system to any<br />

of the customer’s machinery. The hydraulics service<br />

provider supplies complete sets of hoses designed<br />

by OilQuick for the many different makes of machinery.<br />

Where necessary, the OilQuick fitters employ<br />

<strong>FLEX</strong>XPRESS vehicles for the assembly of the sets<br />

on site with the final customer. The advantage of<br />

this close cooperation: <strong>FLEX</strong>XPRESS is fully included<br />

in the manufacturer’s assembly requirements. With<br />

this, OilQuick increases its performance, and keeps<br />

its own capacities flexible.<br />

After just six months, the Augsburg team can therefore<br />

state: “We are already an accepted partner in<br />

the Augsburg region.” This is a great incentive for<br />

the current development of close cooperation with<br />

other customers.<br />

Close cooperation strengthens<br />

the market position<br />

BVV – BOCHUMER VEREIN VERKEHRSTECHNIK<br />

Precision wheels from the coalfields<br />

Baptism of fire<br />

Keeping things rolling<br />

Various production systems were not routinely<br />

overhauled until the end of the year. Entire production<br />

units underwent a thorough overhaul. This<br />

extensive work calls for careful planning every time<br />

- after all, the manufacturing equipment needs to<br />

go back into production on schedule without any<br />

delay.<br />

High-speed trains race along the track at 250 km an<br />

hour. This puts wheels under enormous strain, calling<br />

for maximum reliability. The precision wheels manufactured<br />

by Bochumer Verein Verkehrstechnik (BVV)<br />

for the German and international railway companies<br />

are designed to provide top levels of accuracy and reliability.<br />

This means they are correspondingly dear to<br />

manufacture.<br />

In the historic-looking factory buildings based in<br />

the heart of the coalmining town of Bochum 580<br />

employees use high-tech machinery to produce<br />

some 120,000 locomotive wheels in various configurations,<br />

operating round the clock, seven days<br />

a week. This medium-sized company belonging to<br />

the Georgsmarienhütte Group of Companies has<br />

operated in the steel casting sector since 1841.<br />

Such precision wheels literally go through a baptism<br />

of fire as the special steel, which is alloyed to cope<br />

with the stresses imposed on locomotive wheels, is<br />

heated to a temperature of around 1300 degrees C.<br />

The red-hot block of steel is forged into shape using<br />

a special press with a force of 6,000 t.<br />

Locomotive wheels are made of a single piece of<br />

metal for safety reasons as weld seams are unable<br />

to meet the necessary standards. The red-hot blank<br />

for the wheel, which has been previously sawn into<br />

shape, is processed using a forging press and then<br />

calibrated in subsequent work steps on a 2,000<br />

t press. Next the outer contours of the wheel are<br />

checked by measurement with a laser.<br />

Next comes fine machining, a challenging task that<br />

is performed by robots and high-performance precision<br />

machines at CNC machining centres. At the<br />

end of the production process are wheels which will<br />

run 100% true, down to a hundredth of a millimetre,<br />

and are designed to ensure reliable operation in<br />

heavy-duty rail traffic whatever the weather.<br />

In the planning phase the Repairs, Maintenance<br />

and Service department first of all works out the<br />

level of reconditioning and/or replacement work<br />

required for each machine. This phase also identifies<br />

any leakage. The behaviour of the machines during<br />

production provides pointers about measures that<br />

might be necessary. Such information allows the<br />

company to draw up exact plans for the overhaul<br />

and order all spare parts needed in good time. Surprises<br />

may however still be in store. When panelling<br />

is removed from the machinery, this may reveal<br />

damage and defects that were previously hidden,<br />

such as a leaking hydraulic cylinder or even a unit<br />

with reduced capacity levels. If this is the case, specialists<br />

and technicians from external companies<br />

will have to be called in to help the maintenance<br />

team with the overhaul. The only thing that is certain<br />

in this process is the end date for the service:<br />

that’s definite!<br />

To make sure its machinery and systems are always<br />

ready for operation, BVV involves the service staff<br />

of the machine manufacturers not only in the overhaul<br />

but also in the servicing process. They are of<br />

course familiar with all technical issues relating to<br />

their machines. Here <strong>HANSA</strong>-<strong>FLEX</strong>’s Bochum branch<br />

acts as the specialist for hydraulic hose lines and<br />

repair of the line engineering as a high level of hydraulics<br />

is involved in the forging and rolling mills.<br />

<strong>HANSA</strong>-<strong>FLEX</strong> is also increasingly accepting work<br />

from plant manufacturers when it is a question of<br />

line engineering and services. All services involving<br />

hydraulics are coordinated by Christoph Bergfried<br />

from the Bochum branch - and not just when overhauling<br />

is underway.<br />

<strong>FLEX</strong>XPRESS is contracted to maintain the hydraulic<br />

components of its machinery. Every Friday two<br />

mobile workshops turn up with an comprehensive<br />

stock of spare parts. The crews inspect the hydraulic<br />

systems and carry out urgent repairs to the hose<br />

lines in agreement with the foremen of the individual<br />

All work is carefully documented as BVV is subject<br />

to especially stringent certification as a supplier to<br />

the rail sector. The production systems always have<br />

to be kept in perfect condition as wheels are safetyrelevant<br />

precision components. It must be possible<br />

to reproduce their specified quality standard at any<br />

time.<br />

X-CODEplus ensures transparency<br />

It goes without saying that BVV has opted for<br />

X-CODEplus. As soon as a hose line is replaced,<br />

it is marked with X-CODEplus. Records kept by<br />

<strong>HANSA</strong>-<strong>FLEX</strong> state when each hose line was installed<br />

and why it was replaced: whether it had<br />

to be exchanged due to wear or in the course of<br />

general preventative maintenance. This ensures full<br />

transparency at all times. Weak points are detected<br />

and systematically eliminated. The records for the<br />

hose lines identified with X-CODE can be viewed<br />

at <strong>HANSA</strong>-<strong>FLEX</strong> via the Internet. Stoppages are recorded<br />

there, and this information can be used to<br />

take measures to avoid unplanned downtimes. By<br />

opting for <strong>HANSA</strong>-<strong>FLEX</strong>, a company can increase<br />

the reliability and safety of its machinery, optimise<br />

availability and minimise unscheduled shutdowns.<br />

BVV has opted for system<br />

partnership with <strong>HANSA</strong>-<strong>FLEX</strong>.<br />

Because …<br />

… we appreciate the professional expertise<br />

of its staff and the personal support<br />

offered by the <strong>FLEX</strong>XPRESS service technicians.<br />

And of course the fast delivery<br />

capability of the Bochum branch.<br />

We can drastically reduce our stocks of<br />

hydraulic hose lines, so minimising the<br />

costs of storage and maintenance of<br />

spare parts. And: New hydraulic hose<br />

OIL SERVICE FOR THE EMS BARRIER<br />

Everything shipshape for the magnificent „AIDAbella“<br />

Preventative maintenance on the gateway to the North Sea<br />

Papenburg since 1795 and now boasts the world’s<br />

most modern shipbuilding facilities. Virtually the<br />

entire manufacturing process has been digitised.<br />

Using the so-called “Lego building block principle”<br />

the shipyard not only produces cruise liners but<br />

also special ships such as gas tankers, ships for the<br />

transport of livestock and ferryboats.<br />

The 250 metre or so long Aida Clubschiff carefully<br />

inches its way through the Ems flood barrier. For<br />

the cruise liner built at the Meyer Werft shipyard in<br />

Papenburg, the Ems barrier is the final hurdle before<br />

passing into the open waters of the North Sea.<br />

The Ems barrier at Gandersum is one of the most<br />

modern of its type in Europe and has been in operation<br />

since September 2002. This structure, 476<br />

metres in length, is operated by the Aurich branch<br />

of the Lower Saxony Water Management, Coastal<br />

Defence and Nature Conservation Agency (NLWKN).<br />

Its key function is to protect the German coastline,<br />

in particular from storm surges. If waters rise over<br />

3.70 m above mean sea level (amsl), the gates of<br />

the flood barrier will close off the hinterland, as<br />

happened recently during the autumn storms last<br />

November.<br />

Construction of the storm surge barrier has done<br />

away with the need for continuous adjustment of<br />

the main dykes upstream along the Ems (towards<br />

Papenburg) and its tributaries, something that<br />

would be required every 30 or 40 years according<br />

to experience.<br />

The barrage function of this structure also contributes<br />

to the economic performance of the entire<br />

region by ensuring that the shipping channel<br />

between Papenburg and Emden remains more or<br />

less passable and permits the passage of ships built<br />

at Papenburg’s Meyer Werft on the Ems with a top<br />

water level of 2.70 metres amsl. The shipyard – one<br />

of the biggest employers in the Emsland district<br />

– has an outstanding international reputation for<br />

building upmarket cruisers, with the largest measuring<br />

up to 38 m in width and 300 m in length.<br />

This traditional firm has been constructing ships at<br />

To enable passage of such enormous ocean liners<br />

from Meyer Werft to the open sea, the water<br />

level of the Ems can be raised up to 2.70 metres<br />

amsl. There should be no hitches in this process,<br />

with three such occasions being planned for 2008:<br />

everything is planned down to the finest detail.<br />

Whenever a ship is due to pass through, the flood<br />

barrier has to dam up the Ems to provide the agreed<br />

depth of water on the date agreed. Water has to be<br />

pumped behind the floor barrier depending on the<br />

ship’s draught and the tide level of the Ems. This<br />

task is performed by gigantic pumps with a total<br />

power of 6,300 kW. The combined delivery rate of<br />

the six pumps is some 100 cubic metres per second,<br />

including with fluctuating tide water levels. Water<br />

is taken in via the pump inlet located in the part of<br />

the barrier facing the sea and closed off with steel<br />

flood gates when the pumps are not in operation.<br />

The pumps are installed in six piers, with water<br />

flowing from two sides. They are driven with a<br />

power output of 6,300 kW, forcing water into the<br />

Ems out of pumping channels up to four metres in<br />

width and 2.60 metres in height. The inlet cone,<br />

the suction cone and above all the pump spiral<br />

installed in the piers are prefabricated parts made<br />

of high-grade concrete. The diameter of the impellers<br />

range between 2.25 and 2.6 m. If one of these<br />

pumps breaks down, the decisive inch of water may<br />

responsible for smooth functioning of the barrier<br />

pumps, recently noticed foam in the inspection<br />

glass for the gear oil, he investigated the matter immediately.<br />

The appearance of foam during operation<br />

causes problems with the oil lubricating film,<br />

resulting in increased wear, metal erosion and in<br />

the worst-case scenario, to complete failure of the<br />

pump gear.<br />

As a precautionary measure <strong>HANSA</strong>-<strong>FLEX</strong>’s Oil Service<br />

was consulted to obtain a clear picture about the<br />

condition of the pumps. Samples were quickly taken<br />

and immediately analysed at Wearcheck. Analysis<br />

showed that the tanks contained two different<br />

types of oil whose additives were not compatible<br />

and were therefore producing the foam. Slight<br />

metal abrasion was also observed, originating from<br />

the gearwheels and bearings. It was therefore advisable<br />

to optimise the oil status as a preventative<br />

measure.<br />

Oil change from a single source<br />

Uwe Narten was responsible for coordinating the<br />

complete oil change planned for the installation<br />

with <strong>HANSA</strong>-<strong>FLEX</strong>’s local branch in Emden. The contract<br />

was performed by <strong>FLEX</strong>XPRESS with the service<br />

technician Volker Brodowski. For a week he had<br />

his hands full with all the work on the 400 m long<br />

flood barrier. As agreed in the contract, <strong>HANSA</strong>-<strong>FLEX</strong><br />

had made careful preparations, organising pumps<br />

and filters and also dealing with proper disposal of<br />

the waste oil. In all, 1,500 litres of contaminated<br />

gear oil was pumped out and stored in the containers<br />

standing by. The next step was to flush through<br />

the system with new oil. Here Volker Brodowski’s<br />

brief was to achieve a residual oil level below two<br />

percent and to reliably filter out the abraded metal<br />

particles from the entire installation. Proper disposal<br />

was also ensured for the flushing oil. Only<br />

then was the clean gear oil pumped in, using filters<br />

with an absolute fineness of 3 µ to prevent any new<br />

contamination getting into the system.<br />

Following thorough inspection and the trial run<br />

Uwe Narten now sums up the operation as follows:<br />

“This preventive oil change means that we are well<br />

equipped to deal future tasks - the efficiency of the<br />

installation is assured”. At the end of the interview<br />

he also tells us that passage of the “AIDAbella” will<br />

be possible at the end of March without the help of<br />

the water drawing pumps: there will probably be<br />

enough water in the Ems.<br />

The new way<br />

Further training as hydraulics specialist (HWK)<br />

Wherever one looks in industry today, almost no machines<br />

function without hydraulics. Cranes do not lift,<br />

excavators do not dig, grabbers do not grip, robots<br />

do not assemble and trains do not run without the<br />

aid of hydraulics. It is therefore very surprising that<br />

there is no state-recognised skilled trade of „hydraulic<br />

specialist“, because there is a demand for such specialists.<br />

<strong>HANSA</strong>-<strong>FLEX</strong> has now taken the initiative, in<br />

order to put further training as a hydraulic specialist<br />

on a broader basis.<br />

In order to secure the future demand for specialists<br />

in technical fields, in cooperation with the Chamber<br />

of Trade of Lower Bavaria/Upper Palatinate,<br />

<strong>HANSA</strong>-<strong>FLEX</strong> has developed a further training<br />

concept which concludes with an examination as<br />

a hydraulic specialist by the Chamber of Trade. This<br />

is an opportunity which has been rather neglected<br />

by chambers of trade over the past years, although<br />

it has been included in the training statutes since<br />

1990. The further training is an incentive for good<br />

technicians, for whom up to now there has been no<br />

career path as a skilled tradesman. However, it is<br />

also intended for staff from commercial fields, who<br />

can be employed more flexibly thanks this training,<br />

and for whom new career prospects are opened up<br />

because of their technical know-how.<br />

The first cohort completed its further training as<br />

officially recognised hydraulic specialists with an<br />

examination by the Chamber of Trade in Regensburg<br />

in 2008. The five participants all passed both<br />

the written and the practical examinations with the<br />

grade “good”. Previously, they had all completed<br />

their commercial training with <strong>HANSA</strong>-<strong>FLEX</strong> – a<br />

prerequisite for participation.<br />

The next ones please ...<br />

The next course for hydraulic specialists (HWK) begins<br />

in September 2008. An evaluation workshop<br />

after the first course led to the decision: “We shall<br />

continue, because the growth of the <strong>HANSA</strong>-<strong>FLEX</strong><br />

Group demands a directed development of staff.”<br />

Hydraulic specialist not only help to cover the demand<br />

in technical fields, but also underline <strong>HANSA</strong>-<br />

<strong>FLEX</strong>’s ambition to appear as a system provider.<br />

The training concept has been optimised from the<br />

experiences of the first course. The <strong>HANSA</strong>-<strong>FLEX</strong><br />

personnel development department has specifically<br />

prepared and supervised this process. The optimised<br />

further training now includes a 10-week theoretical<br />

and practical training at the <strong>HANSA</strong>-<strong>FLEX</strong> training<br />

centre in Dresden-Weixdorf and integrated on-thejob<br />

training with neighbouring specialist companies<br />

in Königshofen which manufacture hydraulic<br />

components, or are involved in engineering and<br />

machine construction, special pipes and fittings<br />

and cylinder repairs. For individual special subject<br />

such as electro-hydraulics, lecturers from cooperation<br />

partners are employed - in this case from the<br />

Society for Vocational Training and Further Training<br />

in Hoyerswerda.<br />

On the practical test-beds in Dresden the course<br />

participants deepen their theoretical training with<br />

practical simulations and exercises. During their<br />

training in the fundamentals of hydraulics, the participants<br />

learn to design pressure reservoirs, gain<br />

an introduction to proportional hydraulics, become<br />

familiar with axial piston pumps and their regulators,<br />

and produce circuits according to technical<br />

aspects. The budding hydraulic specialists are also<br />

trained in the design of hydraulic systems and learn<br />

how pipe and hose circuits are dimensioned and<br />

manufactured.<br />

The further training concept also includes technical<br />

fields, which although they are not relevant<br />

to the examination, are essential for <strong>HANSA</strong>-<strong>FLEX</strong><br />

employees, for example pipework technology. Ul-<br />

IHA expands further training<br />

Foundation stone for a milestone<br />

timately the further training course should secure<br />

<strong>HANSA</strong>-<strong>FLEX</strong>’s requirements for specialists and<br />

offer additional vocational prospects to good employees.<br />

The prerequisites for participation in a course as a<br />

hydraulic specialist are firstly a completed vocational<br />

training, and of course very good technical<br />

understanding, great willingness to learn, and<br />

also self-motivation. For <strong>HANSA</strong>-<strong>FLEX</strong> employees,<br />

release by the particular regional manager is also<br />

necessary. Those who complete the course will all<br />

be taken on by <strong>HANSA</strong>-<strong>FLEX</strong> - they know the company<br />

philosophy and after concluding their training<br />

can be employed flexibly. Employees with a Chamber<br />

of Trade Certificate have not only been taught<br />

the theoretical basis of hydraulics, but have also<br />

had experience in the training workshop and in the<br />

associated specialist companies. They are in a position<br />

to answer customers’ enquires about hydraulic<br />

components, to design simple hydraulic systems<br />

and hydraulic cylinders, and to produce pipework<br />

according to customers’ requirements. In addition,<br />

they also gain an insight into cylinder repair<br />

and the manufacture of seals and special fittings.<br />

In future it is planned to open the further training<br />

as a hydraulic specialist to external participants. Interested<br />

customers should contact the <strong>HANSA</strong>-<strong>FLEX</strong><br />

training centre (+49 (0)351-4139719, a.schmidt@<br />

hansa-flex.com).<br />

On 18 April 2008 the foundation stone for the International<br />

<strong>Hydraulics</strong> Academy (IHA) will be laid in<br />

Dresden-Weixdorf. The <strong>HANSA</strong>-<strong>FLEX</strong> Group is participating<br />

in this academy and making its valuable<br />

knowledge from all fields of fluid technology available.<br />

IHA is a reaction to the rapidly growing demand<br />

for courses. The ambitious International <strong>Hydraulics</strong><br />

Academy is a milestone in the field of internal and<br />

external training and further training, as it considerably<br />

expands the previous training and further<br />

training facilities of the <strong>HANSA</strong>-<strong>FLEX</strong> Training Centre.<br />

Through this transfer of know-how, employees<br />

and customers of the hydraulics service provider can<br />

profit from its long years of experience in courses<br />

and training schemes. Additional seminar modules<br />

and an extended staff of trainers, together with the<br />

cooperation with the Technical University and the<br />

College of Further Education in Dresden, enable<br />

all fields of fluid technology to be included in the<br />

course. Additional testing and research capacities<br />

are based on the latest technologies.<br />

HYDRAULIKPRESSE<br />

IN CONVERSATION<br />

Joachim Foltan:<br />

“Ultimately it is a focus on service and sympathy that count”<br />

At the age of 37 years Joachim Foltan is the youngest<br />

regional manager at <strong>HANSA</strong>-<strong>FLEX</strong>. After reorganisation<br />

of <strong>HANSA</strong>-<strong>FLEX</strong>’s Solingen Region, he took over<br />

the operations at Wittlich, Saarlouis, Oberhonnefeld,<br />

Idar-Oberstein, Konz (incl. series production) and<br />

Koblenz. In 2007 the Friedrichsthal-Maybach branch<br />

became the newest member of this region.<br />

Mr Foltan, who started off his career as a commercial<br />

trainee, first came into contact with hydraulics<br />

at a young age. In the holidays he worked for a<br />

construction machinery firm and was responsible<br />

for manufacturing hydraulic hoses when spare<br />

parts were needed. When Joachim Foltan joined<br />

<strong>HANSA</strong>-<strong>FLEX</strong>, he already had a clear idea of his<br />

future. He started work in the Sales department<br />

on 1 July 1996. The first task for the man from<br />

Wittlich was to develop a clientele in the region<br />

south of Trier, the Saarland and adjacent parts of<br />

the Palatinate and to identify the best site for a<br />

new branch: Nine months later saw the founding<br />

of the Saarlouis branch, making Joachim Foltan<br />

the youngest branch manager in the organisation.<br />

Joachim Foltan spoke to HYDRAULIKPRESSE about<br />

his enthusiasm for hydraulics and how this has lead<br />

to a fascination with <strong>HANSA</strong>-<strong>FLEX</strong>.<br />

HYDRAULIKPRESSE: How did it come about<br />

that you opted for hydraulics at such an early age?<br />

Joachim Foltan: I was happy working on the commercial<br />

side of industry and was also successful.<br />

But I was fascinated by hydraulics as well, a subject<br />

that would not let me go. There is hardly any machine<br />

that is not equipped with a hydraulic system.<br />

Whether we are talking about the biggest oil rigs<br />

in the world, gigantic mining excavators, container<br />

ships or operating tables in hospitals, hydraulic systems<br />

make work easier – often without us even noticing.<br />

I have seen hydraulics at work 1,800 metres<br />

down at a coal mine in the Saarland and in a wind<br />

turbine 140 metres up in the air. Fantastic.<br />

HYDRAULIKPRESSE: Your enthusiasm for<br />

hydraulics soon gave rise to a fascination with<br />

<strong>HANSA</strong>-<strong>FLEX</strong>.<br />

Joachim Foltan: I quickly realised that<br />

<strong>HANSA</strong>-<strong>FLEX</strong> is an expanding company that offers<br />

young people every opportunity to take on<br />

responsibility. This meant that during my time at<br />

Saarlouis I was soon able to make the branch a respected<br />

partner in the region as well as a successful<br />

<strong>HANSA</strong>-<strong>FLEX</strong> operation. In addition, <strong>HANSA</strong>-<strong>FLEX</strong><br />

is an innovative company which gives its own impetus<br />

to hydraulics and acts as a trendsetter in this<br />

sector. Here I only need mention X-CODE, which has<br />

revolutionised the procurement of spare parts.<br />

HYDRAULIKPRESSE: In Saarlouis you put<br />

together a strong team, which has even formed<br />

the basis for another branch in Konz. Under your<br />

management the Saarlouis branch personally carried<br />

out an audit as a supplier to the German Armed<br />

Forces in 2005 and passed with flying colours. How<br />

do you manage to pass on your enthusiasm to other<br />

people?<br />

Joachim Foltan: I simply try to communicate<br />

my enjoyment in providing attentive and obliging<br />

customer service to all staff. It’s like this: All our<br />

branches are staffed by committed, well-qualified<br />

people, who mainly have trained as technicians or<br />

workmen. They can work wonders when it’s a question<br />

of technology! But the way in which we stand<br />

out from the competition often lies in the quality<br />

of service. In other words, issues such as “What approach<br />

should I use with customers?”, “How can I<br />

ensure they are happy dealing with our company”<br />

or “How can I solve their problems?”. I would like to<br />

pick up on this, for ultimately it is a focus on service<br />

and sympathy that count with customers.<br />

I myself love selling and always tell my staff: If you<br />

can sell yourselves, the rest will follow of its own<br />

accord. Acting naturally, not putting on a front -<br />

customers notice whether our friendly approach<br />

and manner are genuine or not. With our hydraulics<br />

system partner concept we have fulfilled all conditions<br />

for continued success. But every day we need<br />

to ask ourselves whether we are friendly and attentive<br />

towards customers, and of course competent<br />

as well.<br />

HYDRAULIKPRESSE:<br />

In other words, repeatedly<br />

questioning one’s own success?<br />

Joachim Foltan: That’s important. Although<br />

<strong>HANSA</strong>-<strong>FLEX</strong> is enjoying continuous growth, we<br />

shouldn’t become complacent. This is why I regularly<br />

agree targets with the field team and other<br />

staff at executive level in order to focus customers’<br />

attention on certain products for a while, for<br />

example on sealing technology or currently, the<br />

new programmes for moulded or industrial hoses.<br />

I expect an open approach from everyone to make<br />

sure we can tap into new fields of business. For<br />

example, we recently came up with an innovative<br />

solution for an important customer, who until then<br />

had used costly curved stainless steel pipes for his<br />

line engineering, allowing this component to be re-<br />

H<br />

placed by moulded hoses. This offers the customer<br />

greater flexibility during installation and helps him<br />

avoid the increases in the price of stainless steel.<br />

HYDRAULIKPRESSE: But what about the<br />

motto “never change a running system”?<br />

Joachim Foltan: That’s not my philosophy. If you<br />

always do the same thing, nothing new will ever<br />

result. You won’t notice the changes in the market,<br />

you’ll miss new better solutions. I aim to put<br />

processes in a new light from time to time – and to<br />

change them as well. For as the proverb runs, “Better<br />

is the enemy of good”. I want to avoid complacency<br />

and mindless repetition on the part of staff.<br />

When I took over the region, I also put three<br />

<strong>FLEX</strong>XPRESS vehicles into service. After just a year it<br />

could be seen that customers had been waiting for<br />

this mobile service. Another three vehicles are due<br />

to be added in 2008.<br />

HYDRAULIKPRESSE: Are you setting the<br />

course for the future?<br />

Joachim Foltan: Besides my role as a regional<br />

manager, I am also establishing a foreign business<br />

in Luxemburg as its MD. Luxemburg has always<br />

been a gap in our branch network: until now our<br />

customers there have been managed from Germany.<br />

Luxemburg has big industrial companies, which<br />

are key accounts for <strong>HANSA</strong>-<strong>FLEX</strong> and like buying<br />

in their own country. They are eagerly awaiting<br />

our branch in Luxemburg, which is due to open in<br />

June.<br />

HYDRAULIKPRESSE: Given your level of<br />

engagement, we have to ask how you manage all<br />

this?<br />

Joachim Foltan:<strong>HANSA</strong>-<strong>FLEX</strong> is a great company to<br />

work for. I love my job and still look after important<br />

customers myself. In my case work and spare time<br />

often blur into one. This would undoubtedly not be<br />

possible without my wife Silke. She puts things into<br />

perspective and helps me to cope at times when I’m<br />

under a lot of stress. She assists me in every possible<br />

way, provides excellent advice and pinpoints<br />

the key issues. By the way, we have both booked an<br />

XWORLD trip. On stage 40 of the tour we will be setting<br />

off for exciting destinations from St Petersburg<br />

in Russia. Via the North Cape we will then head for<br />

Scandinavia, a region of the world that my wife is<br />

mad about.<br />

HYDRAULIKPRESSE:<br />

When it comes to<br />

heading for set goals, the responsibilities involved<br />

in the system provider concept also increase the<br />

demands on staff at <strong>HANSA</strong>-<strong>FLEX</strong>.<br />

Joachim Foltan: Here <strong>HANSA</strong>-<strong>FLEX</strong> has responded<br />

by offering to train staff to qualify as a <strong>Hydraulics</strong><br />

Technician (Chamber of Trade). The idea is to show<br />

all employees that if they are committed, they<br />

will be supported by <strong>HANSA</strong>-<strong>FLEX</strong> to take on new<br />

responsibilities every step of the way. If for example<br />

an employee who has been at the workshop<br />

for years feels the urge to try his hand in sales, he<br />

can apply to me. We’ll get together and work out<br />

how he can take on new duties. I have realised one<br />

thing: staff at <strong>HANSA</strong>-<strong>FLEX</strong> like being given new<br />

responsibilities. And this is part of the fascination<br />

exerted by <strong>HANSA</strong>-<strong>FLEX</strong>.<br />

The new BGR 237 is on its way<br />

Focus on practice<br />

But what is new about BGR 237?<br />

Ulrich Hielscher provides us with a brief summary:<br />

“First of all, it goes into great detail. It tells users<br />

of hydraulic hose lines and pipes how they can prevent<br />

damage from occurring in the first place. The<br />

scope of testing and relevant criteria are explained,<br />

and advice on installation and tips from practically<br />

minded experts is also provided. The entire text is<br />

illustrated with plenty of pictures and diagrams.<br />

For example, the new regulation describes circumstances<br />

resulting in failure such as tensile and<br />

compressive loads, temperature influences and the<br />

effect of vibrations. Information about safe replacement<br />

and troublefree fitting of hydraulic hose lines<br />

is not lacking either. This also includes tips on how<br />

to select and order such lines.”<br />

Painted hose lines<br />

Below maximum bending radius<br />

<strong>HANSA</strong>-<strong>FLEX</strong> training manager<br />

Ulrich Hielscher<br />

For many years <strong>HANSA</strong>-<strong>FLEX</strong> has been involved in<br />

advisory boards, specialist committees and working<br />

groups at the employers‘ liability insurance association,<br />

contributing up-to-date specialist knowledge<br />

about hydraulics for the formulation of new standards.<br />

In summer 2008 BGR 237, the new regulation<br />

from the employers‘ liability insurance association<br />

which lays down rules for the safe usage of hydraulic<br />

hose lines, is due to come into force. <strong>HANSA</strong>-<strong>FLEX</strong><br />

training manager Ulrich Hielscher has been involved<br />

in this process in an advisory capacity.<br />

This new regulation will supersede the current<br />

provisions of ZH 1/74 (1988), which also contains<br />

safety rules for hydraulic hose lines, and will provide<br />

operators of hydraulic systems with a practical<br />

guide for the proper handling of hydraulic hose<br />

lines. Today hydraulic lines have to cope with everincreasing<br />

operating pressures, shorter cycle times<br />

and extended machine running periods. This results<br />

in major physical stresses. And this is why the new<br />

considerably more detailed safety regulation has<br />

become necessary.<br />

This makes visual inspection of a hose line by<br />

the operator easier: according to BGR 237 he<br />

has to check whatever he can see. But how often<br />

should such inspections take place?<br />

“Well, the operator has to perform his own risk assessment<br />

on his equipment: it is up to him to decide<br />

when to inspect his hose lines. The recommendations<br />

according to the requirements talk about<br />

every twelve or six months, whereby the specifications<br />

of the machine manufacturer should always<br />

be taken into account as well. The legal basis for the<br />

obligation of inspection can be found in the German<br />

industrial safety regulations, which finalise the<br />

stipulations of the German health and safety law.”<br />

This however also means that any extension<br />

in inspection periods must be tenable and<br />

justified in terms of technical safety. But why<br />

is it even necessary to make regular checks of<br />

hydraulic hoses?<br />

“Major stresses, whether they are mechanical, thermal<br />

or chemical in nature, bring about leakage or<br />

heavy losses of oil or may even cause hose lines to<br />

burst, resulting in machine failures and production<br />

stoppages. Not to mention possible harm to man<br />

and the environment from escaping oil, fires if such<br />

oil catches light in contact with hot machine parts<br />

or ripped hose lines whipping about.”<br />

EMPLOYERS’ LIABILITY INSURANCE ASSOCIATION<br />

H<br />

Operator’s obligations<br />

At the end of the day, the responsibility for compliance<br />

with the safety regulations thus lies with the<br />

manufacturer - but also with the operators of machinery<br />

and systems. It is their obligation to ensure<br />

maximum safety by handling hydraulic hose lines<br />

according to the requirements. “This obligation is<br />

enshrined in the statutory provisions, norms and<br />

the regulations of the employers’ liability insurance<br />

association. This starts with the new machinery<br />

directive 2006/42/EC, which specifically deals with<br />

hydraulic hose lines and connection technology,<br />

and is resumed in the international DIN EN 982<br />

standard listing the safety requirements for fluid<br />

power systems.”<br />

But many operators do not know that ignorance is<br />

no defence - and will not save them from punishment.<br />

This was one of the reasons prompting the<br />

employers’ liability insurance association to introduce<br />

the new BGR 237 safety regulation. Plant operators<br />

are now informed how to deal with safetyrelevant<br />

hydraulic components. Another reason is<br />

that every industrial accident is one too many.<br />

But how can operators spot defects? How can<br />

they see that breakdowns are inevitable?<br />

“For example, from hose lines that are kinked,<br />

brittle or painted, welded fittings, lines that have<br />

been installed so they are too short or are subject<br />

to torsion and abrasion. Another pointer is when<br />

the minimum permissible bending radius is not observed.<br />

What is needed here is proper installation<br />

that takes account of all technical aspects of hose<br />

mechanics. In other words, observe the minimum<br />

bending radius, install hose lines with some slack,<br />

follow the natural curve of the hose line and obviously<br />

avoid wear at points of abrasion and prevent<br />

kinks through the use of curved fittings.”<br />

Sometimes there really is no other way of installing<br />

hose lines. What should you do then?<br />

“The operator or manufacturer should appreciate<br />

that such a hose line will not be installed to optimum<br />

effect! Users must then inspect and document<br />

such lines more frequently under their risk assessment<br />

programme. There are manufacturers who<br />

specify that hose lines subject to such high stresses<br />

have to be replaced after just two years. Operators<br />

should comply with this without fail.”<br />

Recommendation according to DIN 20066 : 2002-10:<br />

For how long hose lines can be utilised?<br />

maxium of 4 years<br />

Age of hose line<br />

A<br />

A = manufacturing date of hose material<br />

B<br />

maximum 2 years<br />

time of storage<br />

for hose line<br />

Well, it’s no doubt true to say that not every<br />

employee at a company can go and check the<br />

hose lines installed in a hydraulic system?<br />

“Here the operator must allocate this task to a socalled<br />

Qualified Person – this is also specified by<br />

law – someone for example who must have undergone<br />

relevant training in this regard. Seminars also<br />

dealing with hose lines are organised by various<br />

institutions such as the Verband der Baumaschinen-Ingenieure<br />

und -Meister (German Association<br />

of Construction Machinery Engineers and Master<br />

Craftsmen). As an active member in this association<br />

<strong>HANSA</strong><strong>FLEX</strong> has already taken part in these seminars<br />

on several occasions. Direct training is also<br />

available at the <strong>HANSA</strong>-<strong>FLEX</strong> training centre for<br />

Qualified Persons responsible for line engineering<br />

and accumulators. As a hydraulic service provider<br />

we additionally organise various seminars at the<br />

centre about the basic principles of fluid technology<br />

for customers, our own staff as well as people<br />

who are not customers of ours. Here a Qualified<br />

Person from the field of line engineering will not<br />

only learn about the correct usage of hydraulic hose<br />

lines, pipework and connection technology but also<br />

the relevant legislation, standards and directives.<br />

Hydraulic oil of course plays a role here, as whatever<br />

contaminates oil presents a risk to hydraulic<br />

hose lines as well.”<br />

One thing we should never forget: hose lines are<br />

not components that will last for ever! “But their<br />

service life can be considerably extended by design<br />

and installation according to the requirements as<br />

well as appropriate inspections including documentation<br />

– something that simultaneously provides<br />

legal certainty”, comments Ulrich Hielscher,<br />

recommending that hose lines are replaced after six<br />

years at the latest.<br />

asked whether the company as a preferred supplier<br />

would be capable of continuously delivering<br />

32,000 parts complying with the specifications of<br />

Terex O&K. Here the Technical Department provided<br />

Sales with efficient back-up and helped shape the<br />

“works in works” concept.<br />

<strong>HANSA</strong>-<strong>FLEX</strong> has developed into a complex business<br />

in terms of applied manufacturing processes and<br />

products. To ensure a sound technical basis for success,<br />

the firm has created the position of “General<br />

Manager Technology” and appointed a key figure<br />

with international experience to this role. Since 1 April<br />

2007 Axel Tammen has been employed as “General<br />

Manager Technology” at <strong>HANSA</strong>-<strong>FLEX</strong>’s Head Office.<br />

In this period Mr Tammen, a graduate engineer for<br />

precision mechanics, has assisted the company in its<br />

transformation towards becoming a system partner<br />

for fluid technology. Here he has shown plenty of<br />

initiative by introducing an optimised process for<br />

the approval or parts and suppliers and so extending<br />

the existing quality management system. “We<br />

intend to further professionalise the entire product<br />

and service quality process,” comments Axel<br />

Tammen, “in order to mould <strong>HANSA</strong>-<strong>FLEX</strong> into a<br />

company offering uniform high quality standards.”<br />

This engineer, who was born in 1962, has extensive<br />

experience in the hydraulics sector, something that<br />

is reflected in his involvement and management of<br />

national and international standardisation committees.<br />

Optimum customer satisfaction is his philosophy.<br />

But to achieve this a rethink will be necessary<br />

in many cases: “in all departments” stresses the<br />

Technology Manager, noting that his own is no<br />

exception. “Here we must develop our expertise as<br />

advisors and a department with inherent responsibility<br />

for technical solutions and offer support to<br />

all <strong>HANSA</strong>-<strong>FLEX</strong> branches and specialist centres of<br />

competence in terms of customer orientation.”<br />

It is not enough, says Axel Tammen, to have all<br />

technical aspects under control. He therefore asks<br />

all staff to “simply look beyond their own noses”.<br />

Axel Tammen also demonstrates this approach in<br />

his spare time. As a keen amateur photographer<br />

who adores taking pictures of animals he uses the<br />

latest camera equipment for his breathtaking shots<br />

of South Africa’s Kruger National Park. He adds<br />

however, “if such photos are to come off, I need to<br />

know how animals behave in the wild”.<br />

The adventure of technology<br />

In the world of work this means “applying the expertise<br />

of the specialists from the Technical Department<br />

so that customers are offered a future-proof<br />

According to Axel Tammen, this support function<br />

will give rise to even greater potential in the<br />

Technical Department in the future. “Customers are<br />

presenting <strong>HANSA</strong>-<strong>FLEX</strong> with increasingly complex<br />

problems,” one reason why he wants to involve<br />

this department in the overall development of the<br />

company more closely. “We are already pretty good,<br />

but we want to be even better, and this can best<br />

be achieved if customer satisfaction is increased.” A<br />

philosophy that is going to be used by Axel Tammen<br />

to make a few more changes at <strong>HANSA</strong>-<strong>FLEX</strong>.<br />

But for the time being it is the XWORLD Tour with<br />

its exciting offroad routes that is occupying his<br />

thoughts. “This is pure delight. I can only hope that<br />

every participant will enjoy this fantastic experience.”<br />
