PURPOSE

The hydraulic towing winch jointly with control system and the pump station is designed for towing the crafts, which have no propulsion devices of their own, to the place of destination and backwards. 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:

  • two hydraulic motors МГ40;
  • disk brake fixing the drum position with motors deenergized;
  • reduction gear;
  • drum;
  • band brake;
  • rope-laying device.

The winch has a support frame secured to the ship’s foundation.
