The invention discloses a compact hydraulic winch in the technical field of hydraulic winches for engineering machinery, the hydraulic winch comprises a support, a hydraulic motor, a secondary planetary system, a primary planetary system and a winding drum, the hydraulic motor, the secondary planetary system, the primary planetary system and the winding drum are mounted on the support, and the hydraulic motor transmits power to the winding drum through the primary planetary system and the secondary planetary system. The winding drum is driven to rotate; wherein the first-stage planet carrier and the second-stage sun gear are connected through a high-low tooth and axle bumper structure, one side of the second-stage sun gear is positioned through a high-low tooth end face, the other side of the second-stage sun gear is positioned through an axle bumper, the second-stage sun gear is meshed with the second-stage planet gear, and the second-stage planet gear is connected with the second-stage planet carrier through a second-stage planet gear bearing. The first-stage sun gear is meshed with a first-stage planet gear, and the first-stage planet gear is connected with a first-stage planet carrier through a first-stage planet gear bearing; the winding drum is rotationally connected with the support through a rear bearing and rotationally connected with the second-stage planet carrier through a large bearing. Spatial layout can be optimized, and the performance and reliability of the winch are improved.
