ABSTRACT:
An electric hoist with motor-speed-regulated lifting speed, in particular an electric chain hoist, including an electric motor, a gear unit, and a wheel around which the hoisting chain is looped. A load-carrying device is arranged on the hoisting chain. The motor, gear unit and wheel are connected with one another in a drive connection and the lifting speed is provided by an electric control unit for the electric motor, which control unit is connected to a manual control switch. In order to achieve suitable cooling while apportioning the space in an appropriate manner for the arrangement of all required components, the electric control unit, which has control electronics with speed sensing equipment, is arranged in an external protective housing fitted to the gear box.
