Heavy machine drives

Whether as drives for heavy hydraulic forging presses, large closed-die forging presses or steel extrusion presses or as drives for heavy marine hydraulics, our oil-hydraulic drive units are designed for maximum reliability, durability and, above all, the lowest possible power consumption This is our way of not only providing our customers with the highest possible productivity and profitability, but also making a meaningful contribution to the preservation of our environment.

A special feature of our drive systems is the shock-free and energy-saving PMSD drive, in which the operating cylinder are driven directly by our servo-controlled high-pressure radial piston pumps without the interposition of control or regulating valves.

Our small drive units start at 500 kW of installed capacity. With our large plant of 30 MW of installed capacity, we without a doubt have delivered the world's largest hydraulic system.

 

Our most powerful hydraulic system to date

Based on the PMSD drive, we designed and supplied the 42-pump drive (RX 500), the most powerful hydraulic system in the world. With an installed capacity of 30 MW it operates a 360 MN steel extrusion press combined with a 150 MN pre-forming press at Norheinco, China.
