Heavy duty hydraulic cylinder
6 500 kN HUNGER Hydraulik

Hydraulic drive systems for moveable bridges have to satisfy highest safety demands. Beside hydraulic cylinders for bascule bridges, rotatable bridges or lift bridges we also produce special cylinders for ferry bridges and passenger terminals.
For the Canary Wharf project in London for example a special telescopic bridge lifting cylinder was developed to lift up one side of the bridge leaf by up to 18 m. The hydraulic cylinder with a capacity of 6,500 kN is equipped with externally adjustable seal systems Hunger EVD as well as with a load release coupling element at the road end.

The hydraulic cylinder has a length of 35 m, when fully extended and is Ceraplate coated.
