G80 clevis self-locking hooks are used to fit with G80 chains. The clevis is more easy to fit into the chains. After loading the chains into the clevis part, we punch the load pin on one end of the clevis to fix the assembly.
We have improved our self-locking hook to make it more safe: positive lock latch is self-locking when the hook is loaded. The hook has also been processed quenched and tempered. Heat treatment of metal materials is an important method to improve and improve the performance of parts. Therefore, heat treatment is and indispensable technology in the manufacturing process of G80 lifting hooks.
