The invention provides a hydraulic capstan, and belongs to the technical field of machinery. The hydraulic capstan solves the problems that an existing hydraulic capstan is not compact in structure and not convenient to disengage and engage. The hydraulic capstan comprises a motor, a coiling block, a left bracket, a right bracket, a left connecting base, a right connecting base and a shell; a motor shaft is connected with a spline transmission shaft, and a braking assembly is arranged between the spline transmission shaft and the shell; one end of the braking assembly abuts against an inner shell through a stopping block, and a spring assembly is arranged between the other end of the braking assembly and the left connecting base; the left bracket is provided with an oil nozzle; the spline transmission shaft is engaged with a primary planet gear, and a planet gear carrier is arranged on the two sides of the primary planet gear; an air cylinder is arranged in the middle of the right bracket, a clutch pulling rod is arranged in the air cylinder, and the end portion of the clutch pulling rod is connected with a secondary sun gear; one end of the secondary sun gear is engaged with the planet gear carrier, and the other end of the secondary sun gear is engaged with a secondary planet gear which is engaged with the coiling block; the right connecting base is provided with an air nozzle. The hydraulic capstan has the advantages that the structure is compact, and disengagement and engagement are rapid.
