The Revox® S compose a standard gear unit to start-up high rotatory inertia in particular for crushing operation.

Drive systems for constant speed engines are subject to high requirements during acceleration of the rotor.

Due to the high engagement speed of the clutch an increase of the performed friction work raised which lead to a high wear.

The Revox® S dispose of a hydraulic soft start system which handle the risk of high friction work by a soft start-up device which means of a hydraulic gear motor. This enables a wear reduced start-up procedure even at high engine speeds up to 1500 rpm.

During operating mode a robust wet clutch transmit the engine torque. The mechanical direct drive system lead to a energy- efficient drive solution.

The Revox® S is provided with a SAE B-B hydraulic pump con- nection by default.
