The invention discloses a compact type double-grade large-torque hydraulic winch comprising a support, a power piece, a coiling drum, a first-grade planetary gear reducer and a second-grade planetarygear reducer. The power piece is fixed to the support. The front end of the coiling drum is rotationally connected with the power piece through a second bearing. The back end of the coiling drum is rotationally connected with the support through a first bearing. The coiling drum is provided with a boss. The first-grade planetary gear reducer comprises a first-grade sun gear, a first-grade planetary gear, a first-grade planetary gear bearing and a first-grade planetary frame. The first-grade sun gear is connected with the output end of the power piece and is located on and abuts against the boss of the coiling drum. The second-grade planetary gear speed reducer comprises a second-grade sun gear, a second-grade planetary gear, the second-grade planetary gear bearing, a second-grade planetaryframe and an inner tooth ring. The second sun gear is connected with the first-grade planetary frame. The second-grade planetary frame abuts against a stop block of the end face of the power piece. The inner tooth ring is fixedly connected with the coiling drum. The compact type double-grade large-torque hydraulic winch is short in axial structure, small in overall volume and compact in internalstructure.
