Chains are one of the most common slinging equipment and are widely used due to their ductility and resistance to traction, abrasion and high heat.
The process of making chain
After the melting process, the chain rings are formed by the process of welding or gas welding and enter the heat treatment stage. After this step, the chain is ready to perform the Proof Test.
By a special device, a certain length of the chain is connected to the two jaws of the device and a certain force is applied to the chain sample at a certain time and the results are evaluated according to the relevant tables.
Chains are made in different types and are usually classified based on the number of stems (Leg) and the type of components.
