Abstract

The electric chain block or hoist comprises a self-braking electric motor operatively connected to an epicyclic redn. gear for driving a member meshing with a chain. A central input shaft (1) of the gear is rotatably supported in a cantilever manner by associated bearings (3,4) and a gear (2), with which the chain (C) is coupled, and which forms a unitary body with the movable gear (7) of the redn. gear. A counterweight (19) is provided to determine a max. load friction which can be applied. A self-braking electric motor for driving the input shaft (1) has a rotor comprising a series of conical packets surrounded by an air gap, and a brake is positioned within one of the motor winding heads. The appts. requires reduced floor space and avoids undue lateral overhang.
