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,Wire rope winch four teeth and minor axis spline Kong gears. Thus, the device lifting sprocket holes on the spline drive gear on lifting chain, lifting heavy objects smoothly.Chain block hoist rotary gear after high temperature heat treatment to achieve a high gear, according wear. Explosion-proof chain hoists bracelet pull small, light weight, easy to carry, beautiful appearance, 15 ton electric chain hoist small size, durability. aluminum bronze, beryllium copper as a blank, Chain block H62 copper alloy shell with proof chain hoists applicable in explosive environments, such as chemical, offshore and other operations.
