Claims

[Scope of Claim for Utility Model Registration] In an electric hoist that moves along a rail by rotating a moving rotating body with a moving motor, and hoists and unwinds a wire rope by rotating a pulley with a hoisting motor. , a stator cone having a conical surface, a plurality of electromagnets disposed along the circumferential direction around the stator cone, and a conical shape and arranged inside the stator cone, and the stator is attracted by the electromagnetic force of the electromagnets. a rotor that rolls on the inner peripheral surface of the cone;
The moving motor and the hoisting motor are constituted by a variable freewheel motor having a joint that transmits the rotation of the rotor to the shaft, and the shaft of the moving motor made of the variable freewheel motor is directly connected to the moving rotating body. An electric hoist further characterized in that a shaft of a hoisting motor comprising a variable air motor is directly connected to the pulley.
