Electro Hydraulic Power Pack to Drive 4 Wheel Pair Cable Engine

 

The unit provides power to drive the 4 wheel pair cable engine.

 

The unit comprises an electric motor driving a variable displacement hydraulic pump, linked to gear type pumps, all to power the motors and hydraulic cylinders of the 4 wheel pair cable engine. Water coolers are provided in the hydraulic circuit to stop the system over heating.

 

The unit and the 4 wheel pair cable engine are controlled from the hydraulic pilot operated consul mounted on the cable engine. The unit provides hydraulic power to drive the cable engine wheels when hauling and powers the hydraulic cylinders, which exert the required grip pressure between the wheels onto the cable. The unit also includes the necessary valves and controls to operate the cable engine as a hydraulic brake, for use when laying cable, maintaining the required speed and back tension to the cable during this operation.

 

A separate electrical and water supply is required to operate this unit.
