ABSTRACT:
A fluid system having a variable displacement fluid pump connected in a closed-loop fashion to a hydraulic motor-driven winch of the spool type. A directional control valve connected between the pump and motor selectively directs fluid to the hydraulic motor-operated winch to control the direction of movement thereof. The hydraulic winch is provided with a pressure responsive brake that is normally set to brake the winch and prevent its operation, while fluid under pressure communicated to the brake will release the same and permit the winch to operate. A separate source of fluid pressure is provided and selectively communicated to the hydraulic brake of the winch through a directional control valve, while a second control valve is provided for exhausting the control pressure to the reservoir in the event the main system pressure drops below a predetermined value. In such situations the brake control pressure is vented and the brake operates instantly to prevent further movement of the hydraulic motor-operated winch.
