Revox® Hydraulic start-up Gearbox

Thanks to the new Revox® drive concept, a gear coupling unit, it has become possible to combine an energy-saving direct drive with the versatility of hydraulic drive technology. The core of this drive system is a power-split drive train. A hydraulic motor mounted either side takes care of the starting process to ensure gentle, safe start-up of the crusher rotor. Highly sensitive electronic control systems can be dispensed with.

The Revox® S consists of a hydraulic soft start system which handles the risk of high friction work by a soft start-up device by means of a hydraulic gear motor. This enables a wear reduced start-up procedure even at high engine speeds up to 1,500 rpm.

During operating mode a robust wet clutch transmits the engine torque. The mechanical direct drive system results in a engergy efficient drive solution.
