Abstract

Hydraulic system for driving a winch, which includes a hydraulic motor for driving the winch, a pump to pump hydraulic oil for driving the motor, a control valve for controlling the speed of the motor and the direction of rotation, a first valve throttle valve that is connected in series with the pump, and a second throttle valve that is connected in parallel with the motor, characterized in that it includes two or more hydraulic motors (2a, 2b, etc.) connected in parallel, with direct flow in both directions, preferably of the multi-stage type, and connected for actuation to the same axis as the winch.
