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.
