As the name suggests, explosion-proof chain hoists are suitable for use in flammable and explosive situations, such as chemical industry, offshore and other operations.

Explosion-proof hand chain hoists are generally made of aluminum bronze and beryllium bronze. The rotating gears undergo high-temperature heat treatment to achieve high wear resistance of the gears.

The chain is not made of pure copper, because there is a certain gap between the tensile strength and toughness of pure copper and manganese steel, so the chain is made of manganese steel as the main material

The surface is made of nickel-plated copper alloy, which not only ensures tensile strength and toughness, but also prevents flammability and explosion.
