The invention provides a hydraulic control system for a brake of a winch, and belongs to the technical field of hydraulic control. The hydraulic control system comprises a power unit, an oil inlet unit, an oil return unit and an oil suction unit. The oil inlet unit is connected with the power unit; the oil return unit is respectively connected with the brake and the oil tank, the oil suction unit comprises an oil suction control valve and an oil suction pump, a first oil port of the oil suction control valve is connected with the brake, a second oil port of the oil suction control valve is connected with an oil inlet of the oil suction pump, an oil outlet of the oil suction pump is connected with the oil tank, and the oil return unit is connected with the oil tank. When the brake needs to be quickly switched on, the oil return unit guides pressure oil in the brake into the oil tank, meanwhile, the first oil port of the oil suction control valve is communicated with the second oil port of the oil suction control valve, and the oil suction pump drives the pressure oil in the brake into the oil tank. The present disclosure may enable a brake to quickly brake a winch.
