The invention relates to a hydraulic winch with a pneumatic clutch. The problems that an existing hydraulic winch is complex in clutch structure, unfavorable to running stability and not compact enough are solved. The hydraulic winch comprises a rack, and a hydraulic motor, a reduction gear and a coiling block are sequentially arranged on the rack in the power conveying direction. The hydraulic winch is characterized in that a planetary gear train serves as the reduction gear and is at least in primary planetary gear transmission; a primary sun wheel and the hydraulic motor are connected through a sun wheel shaft to be used as power input; a gear ring is fixed to the inner wall of the coiling block as power output; a spline shaft is arranged at the end, connected with the hydraulic motor, of the sun wheel shaft; the primary sun wheel is arranged outside the other end of the sun wheel shaft; a pull rod is connected with the end, with the primary sun wheel, of the sun wheel shaft; and a handle for controlling the pull rod to stretch out and draw back is arranged at the other end of the pull rod. The structure is compact, no additional device is added on a transmission path, and running stability is good.
