In addition to the electric hoists, the lifting mechanism is used also in winches, chain hoists, and other hoisting and transport equipment. It possesses an increased capability of reaching the necessary parameters, ensures even loading of the gear meshings, high-revolution electric motors are used that are lighter, cheaper and work with lower dynamic loads. The lifting mechanism consists of an electric motor (1) assembled on the front side of a body (2) and connected through a shaft (12, 13) to the sun gear (10) of a first planetary gear (9). An end gear (4a) is connected by its vehicle (4c) to slots of large diameter with the ring (5) of the tooth coupling (5 and 6).
