The invention aims at providing a two-stage planet winch. According to the two-stage planet winch, a sun gear is fixed to an input shaft and is coaxial with a drum shaft, the input shaft is combined to a gear ring through a bearing, planetary discs are fixed to one end of the drum shaft, and the parts are jointly fixed to a machine frame through a bearing support and a gear ring overlaying clamp to form a first-stage planet structure; a drum is combined to the drum shaft through a bearing, a sun gear of a second-stage planet structure is fixed to the other end of the drum shaft, a planet gear is combined to a drum disc, and the gear ring is combined to the drum shaft through a bearing and meshed with the planet gear to form the second-stage planet structure. Obviously, when the gear ring is directly fixed to the machine frame through the bearing support, the non-clutch-type two-stage planet winch is obtained; when the gear ring is indirectly fixed to the machine frame through a band-type friction device and the bearing support, the clutch-type two-stage planet winch is obtained. An electric-control or spiral-self-control device and the like are arranged on the input shaft. The two-stage planet winch has the advantages that the structure is simple, combining is tight, the size is small, weight is small, use is convenient, energy is saved, and efficiency is improved.
