The cover of the chain hoist not only protects the internal parts from damage, but also allows us to understand the specifications and models of the hoist through the nameplate on the cover, making it convenient for us to carry out operations.

The cover of the aluminum alloy chain hoist also has anti magnetic function, the cover of the stainless steel chain hoist has anti-corrosion function, and the cover of the explosion-proof chain hoist has explosion-proof function. Compared with the cover made of ordinary manganese steel material, the cover made of special materials is more expensive.
