A device for supplying and modifying the cylinder cubic capacity of a hydraulic motor, comprising: a first conduit (1) for supplying and discharging an operating fluid to a first side of the hydraulic motor (M); a second conduit (2) for supplying and discharging an operating fluid to a second side of the motor (M); an actuator (3) provided to modify the cubic capacity of the motor (M); an increase conduit (31) for increasing the cubic capacity of the motor (M), connected to the actuator (3) for supplying operating fluid to a side of the actuator (3) which produces an increase of the cubic capacity of the motor (M); a reduction conduit (32) for reducing the cubic capacity of the motor (M), connected to the actuator (3) for supplying operating fluid to a side of the actuator (3), which produces a reduction of the cubic capacity of the motor (M). The device is structured to supply to the increase conduit (31) and to the reduction conduit (32) a proportional pressure to the load acting on the winch.
