Chain Proof Testing Machines

Main Function：

Our Chain Proof Testing Machine is engineered specifically for proof load testing (also known as manufacturing proof force testing) of industrial grade chains. This critical quality assurance process applies a controlled, predetermined tensile force—significantly higher than normal working loads—to verify the chain’s structural integrity, safe working load capacity, and tensile strength.

During the test, the chain is subjected to a heavy, standardized load without exceeding its elastic limit. Successful performance—defined by minimal elongation and zero failure—confirms the chain meets or exceeds international safety standards. Passing this industry-standard proof load test certifies that the lifting equipment is 100% safe for operational use, significantly reducing the risk of accidents during heavy-load handling.
