With the development of the all-terrain (AT) cranes, which are used universally, these products have created a unique leading position for themselves worldwide.
Montanhydraulik supplies safety-relevant components for these machines, in the form of telescopic, rocking, and support cylinders, hydraulic accumulator cylinders, and rotary feed-throughs; these have been developed in close collaboration with our customers. Here, the range includes the small city crane with payloads of 25 t, as well as the nine-axle giant crane with payloads up to 1,000 t and jib lengths up to 100 m.
The demands placed on the various cylinders range from weight optimisation, which requires the use and machining of very thin-walled barrels, to suitability for low temperatures at which cylinders must work reliably and safely.
Single and multi-step telescopic cylinders with internal oil supply and lowering brake valves, which Montanhydraulik developed specifically for this application, are an example of the company’s know-how.
