A winch hydraulic control system comprises a hydraulic oil tank, a hydraulic pump and a motor, an oil inlet of the hydraulic pump is communicated with the hydraulic oil tank, the motor is connected with the hydraulic pump, and an oil outlet of the hydraulic pump is communicated with a P port of a main reversing valve set and a P port of a control valve set. A port A and a port B of the main reversing valve set are communicated with a first shuttle valve, a port A of the balance valve set and a port B of the control valve set respectively, a port X is communicated with a port B of the second electromagnetic reversing valve, a port B and a port C of the first shuttle valve are communicated with a port B of the balance valve set and a port B of the second shuttle valve respectively, and the third pressure reducing valve is connected to the second electromagnetic valve in parallel. A P port of the second electromagnetic reversing valve is communicated with an X port of the control valve set, an A port of the second shuttle valve and an SP port of the balance valve set, a C port of the second shuttle valve is communicated with a rod cavity of the brake, the brake is connected with the hydraulic motor, and an oil outlet of the control valve set is communicated with an oil inlet of the balance valve set. Constant tension of the steel wire rope can be kept, and operation is stable.
