Within the production of brown coal, gravel and sand as well as other mineral resources hydraulic cylinders are used for surface and underground mining. We work on specific solutions around the hydraulic and pneumatic transportation, as for example paddle-wheel hydraulic jacks.

In underground and surface mining rotary breaker machines are used for shattering big pieces of rock. To avoid damage through overstressing, special designed rotary breaker cylinders are utiliesed as hydraulic controlled compensating element. Those cylinders have to guarantee a maximum reliability under extreme application conditions, for example dust and high dynamic load.
