Explosion Chain Block

Explosion Chain Block: aluminum bronze, beryllium copper as a rough, chain hoists H62 copper alloy shell with proof chain hoists used in explosive environments, such as chemical,cheap wire rope hoist offshore and other operations. Explosion Chain Block rotation gear after high-temperature heat treatment to achieve a high gear, according wear resistance. Explosion-proof chain hoists bracelet pull small, light weight, easy to carry, beautiful appearance, small size, durability.
Explosion Chain Block work principle: through hands-chain drag chains, bracelets wheels began to turn, friction ratchet, brake seat (to be pressed into one) co-rotating, five major axis will rotate sprocket teeth, four teeth and minor axis spline hole gear lever hoist manufacturers Thus, the device lifting sprocket holes on the spline drive gear on lifting chain, lifting heavy objects smoothly.
