The winch storage hydraulic system comprises a pilot overflow valve, a motor and an oil tank, the oil tank is provided with a first oil port and a second oil port, the first oil port is connected with the oil inlet end of the motor through a first oil outlet pipeline, and the oil outlet end of the motor is connected with the second oil port of the oil tank through a first oil return pipeline; a pilot-operated overflow valve is arranged between the first oil outlet pipeline and the first oil return pipeline, the oil inlet end of the pilot-operated overflow valve is connected with the first oil outlet pipeline, the oil outlet end of the pilot-operated overflow valve is connected with the first oil return pipeline, and a pilot-operated oil way of the pilot-operated overflow valve is connected with an oil tank through a first switch valve. The first switch valve is in a closed state when not reversing, the pilot oil way of the pilot overflow valve is further connected with a first oil outlet pipeline, and hydraulic oil of the first oil outlet pipeline flows into the pilot oil way of the pilot overflow valve to drive an internal oil way of the pilot overflow valve to be closed. By means of the structure, the motor can be controlled to rotate stably when the winch winds the cable, and the cable is kept in a constant-tension state.
