The company Boerkey is the inventor of the Roller Skate Express. By the help of this mechanical product, loads of several tons can be moved easily and safely.

The basic principle of the Roller Skate is based on a simple but ingenious idea: Already during the construction of the pyramids in Egypt, heavy components were moved by rollers, but the released rear roller always had to be brought manually forward under the load.

In the case of the Roller Skate, this happens automatically, as the rollers are joined by links to form a roller chain. This significantly reduces the risk of accidents and allows an easily and continuous transport.

Since 1951, the Roller Skate has been manufactured in Hagen in Germany and is successfully used by our customers worldwide.


As a supplement to our product range, we have been producing very robust heavy duty rollers and heavy duty trolleys for many decades.

In the following, we would like to show you a small excerpt from our projects for moving heavy loads ….

Nuclear Research Centre in Genf

Participation for example at the L3, LHC and CMS Experiment at Cern

In the Nuclear Research Center CERN in Genf, elementary particles are accelerated in a ring accelerator and brought to a collision. For example, in the Large Hadron Collider LHC, hydrogen nucleus are brought to a collision with a speed  that is close to the speed of light and with heavy detectors they try to research for the conditions at the time of the Big Bang. 

For the positioning of the detectors and the maintenance of the accelerator magnets, our Roller Skates have been used for decades. For the project that we show here, Roller Skates V AS-H-50CrV4(-FR-E) with a maximum vertical capacity of 85 tons were used.

Also at other Nuclear Researsch Centers with ring accelerators, e.g. DESY in Hamburg or JINR in Dubna/Moscow, our Roller Skates with maximum loads of up to 500 tons are used.

Arena of Schalke

In the year 2001, the Arena of Schalke in Gelsenkirchen was opened after three years of construction phase. One highlight of this multifunctional arena is the movable, 750 tons heavy and 82 meters wide lower rank of the south tribune.

Depending on the kind of event taking place in the arena, it is possible to move the tribune , having space for 8000 spectators, by 18 meters.

To manage this, the Boerkey GmbH designed and  produced two Twin Skates with a capacity of 500 tons and four Twin Roller Skates with a maximum load capacity of 200 tons.

Blast furnace

An old blast furnace in a Chinese steel mill had to be removed to provide space for a new, more powerful one.

The new one was supposed to be placed at exactly the same spot as the old one. To keep the production downtime as low as possible, the new furnace, wich weights 4000 tons, was build next to the old one and after its dismantling it was moved to the previous position.

Ispad in Kasachstan

In a steel mill in Kasachstan a Steel ladle bogie was built, wich additionally has a rotating function for the steel ladle.

For this purpose Börkey GmbH designed and delivered sets of wheels, wich travel on a predetermined circular path to make the rotation possible. Each of the sets has a maxiumum capacity of 90 tons.

The sets of wheels  have contributed to significant cost savings versus other technical solutions.
