The outer side of the right end of the coiling block is provided with a lifting brake ring through an end cover. An inner gear ring is pressed to the inner side of the right end of the coiling block. A lifting band-type brake is installed on the lifting brake ring. A center gear is installed at the right end of the winch shaft. Three planetary gear supports are evenly distributed. Each planetary gear support is provided with a planetary gear shaft which is provided with a planetary gear through a single-row radial ball bearing. Each planetary gear support is sealed through an installed sealing cover.
