The invention belongs to the field of engineering machinery, in particular to a hydraulic winch device of bulldozer 160 series. According to the adopted technical scheme, when a winch is used, after the hydraulic oil of a pipeline passes a reversing valve, a clutch is opened, and a hydraulic motor is in an operation state to control the winch to operate. No matter a scarifier valve is in a left position or right position, the oil flowing into a heat radiator is maintained in an oil return way and is cooled through the heat radiator before flowing back to a hydraulic oil tank via the scarifier valve, the hydraulic oil is in a cooled state constantly, and the problem of winch heating is solved.
