The wire rope electric hoist features a serial arrangement of the hoisting motor, drum assembly, and reducer, with a round or square appearance. It provides vertical lifting and traveling functions and is available as CD1 single-speed or MD1 dual-speed.

The dual-speed MD1 hoist adds a slow-speed drive system, consisting of a slow-speed motor and reducer, to the single-speed design, with a speed ratio of 10:1 between fast and slow speeds. When the fast motor operates, the slow-speed drive remains idle, allowing rapid lifting and lowering. When the slow motor operates, it drives the main hoisting motor’s conical rotor through the slow-speed drive, enabling slow and precise lifting and lowering.
