PURPOSE

The hydraulic cargo winch jointly with control system and the pump station is designed for cargo handling. Stopping and braking of the drum is provided at any time as well as control of the amount of cable out.

DESIGN

The winch main functional elements:

  • cargo drum;
  • four hydraulic motors МГ40;
  • two disk brakes fixing the drum position with motors deenergized;
  • two reduction gears (cylindrical and planetary);
  • manual band brake;
  • rope-laying device.

The winch has a support frame.
