The chain hoist is a light and small lifting device. The electric chain hoist consists of an electric motor, a transmission mechanism and a sprocket. The electric chain hoist is produced in accordance with international standards. The internal gears are all quenched at high temperature, which increases the wear resistance and toughness of the gears. The gears fit tightly.

The body is made of high-strength tensile shell or die-cast aluminum shell, which is precision manufactured by thin-wall extrusion molding process.
The standard electric chain hoist has a separate gearbox system, a two-stage coaxial transmission gear mechanism in the sealed gearbox, and a long-life oil bath lubrication system.
