Product description chain according to different uses and functions divided into transmission chain, enhance chain www.yzcclt.com, traction chain and for special chain of four. 1.1 Main transmission chain for transmitting power chain. 1.2 conveyor chain is mainly used for transport of materials. 1.3 traction chain is mainly used for pulling and lifting chain. 1.4 for special chain is mainly used for special machinery and equipment, with special function and structure of the chain. Structure: in its class, according to the basic structures of the chain, which belongs to the chain product range is divided according to element shapes, replacement parts and parts of the engagement with the chain, the size ratio between the parts and so on. Many types of chain, but their basic structure, only the following, the other is these types of deformation.
