The lifting chain is a chain that can be widely used in mines. The safety of the lifting chain is high, but the chain cannot be welded. Let's analyze it in detail below.

The lifting chain is composed of multiple chain links. The size and pitch of each chain link are specified. On the same lifting chain, these data should be equal, but if it is welded after welding, The link data will be different from the data of other unwelded links, which will affect the service life of the entire lifting chain.

First, the welded chain will have obvious traces, but during the lifting process, the chain runs within the lifting sprocket, and the increase in the data of the chain will increase the wear of the chain and the sprocket and reduce its service life.

Second, welding will destroy the integrity of the chain. During lifting work, the load-bearing capacity of the welding part will be weakened, increasing the risk of chain breakage.
