The invention relates to a full hydraulic winch with a free lowering function. A winch frame comprises a left side frame support plate and a right side frame support plate parallel to each other, a reel body is located between the left side frame support plate and the right side frame support plate, and a hydraulic clutch and a planetary gear reducer are arranged inside the reel body. A hydraulicmotor is fixed on the outer side face of the right side frame support plate, a hydraulic brake is fixed on the inner side face of the right side frame support plate, and an output end of the hydraulicmotor is dynamically connected to a power input end of the hydraulic brake. A bearing I is installed on the outer wall of a housing of the hydraulic brake, an outer ring of the bearing I abuts against the inner wall of the right end of the reel body, and a power output end of the planetary gear reducer is dynamically connected to a power input end of the hydraulic clutch. The winch has the following beneficial effects that the structure is compact, an empty lifting hook can be lowered at full speed, and the work efficiency of the winch is improved.
