ABSTRACT:
The invention is concerned with improvement in a vehicle supported winch which comprises a supported rotatable drum for receiving and releasing a cable, a drive train for selectively transmitting rotary motion to said drum having clutching apparatus and breaking apparatus, a pump serving as a source of pressurized fluid and valves communicating the pump for selectively controlling application of the pressurized fluid to the clutch apparatus and the brake apparatus. The improvement comprises an accumulator communicating with the pump for storing the pressurized fluid produced by the pump when it functions and for supplying the pressurized fluid when function of the pump is retarded. A transmission is driven by an engine of the vehicle and drivingly connected to drive the drive train to selectively transmit rotary motion to the drum. A pump drive apparatus drivingly connects the pump to be driven by the transmission of the vehicle. Functioning of the pump is retarded as the transmission stalls. When functioning of the transmission is retarded the accumulator supplies the necessary pressurized fluid.
