The CD1 and MD1 type wire rope electric hoists are a kind of light and small lifting equipment. It can be installed on various types of cranes such as single-girder hoists, bridge cranes, gantry cranes, cantilever cranes and rail-crossing cranes. By changing the installation method, it can also be used as a fixed winch. Therefore, it is one of the commonly used lifting devices in factories, mines, ports, warehouses, freight yards, coal chemical plants, smelting plants and other places, and is an essential mechanical device for improving labor efficiency and working conditions.

The lifting speed of the CD1 type electric hoist is single speed, which can meet general usage requirements. The MD1 type electric hoist has two lifting speeds - fast and slow. When working at a slow speed, it can meet the requirements of precision loading and unloading sites, such as sand box mold closing, machine tool maintenance, equipment assembly or repair, and other fine operations. Therefore, the application scope of the MD1 type electric hoist is wider than that of the CD1 type electric hoist.
