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 />

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 />
specially produced for this purpose by the PTFE<br />
hose experts at Boffzen, are used here as they are<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 />

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 />

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 />

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 />
be lacking that allows a ship to pass into the open<br />
sea in the scheduled time slot.<br />
A timely oil check<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 />

<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 />

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 />
