What is the maximum elongation rate of a chain that is still safe for use according to labor regulations?

In the context of forklifts and lifting equipment, the elongation rate of a chain under working conditions is a critical factor in ensuring safety. Labor regulations typically stipulate that a chain can be considered safe for continued use as long as its elongation does not exceed a certain threshold.

An elongation rate of 3% is often identified as the maximum allowable elongation for the safe operation of lifting chains. Chains can experience wear and deformation over time due to repeated loading and unloading cycles. Exceeding this elongation limit may compromise the chain’s integrity, leading to potential failures that pose serious safety hazards.

It's important to regularly inspect chains for elongation, as exceeding this threshold not only indicates potential defects but may also violate safety standards. Monitoring elongation helps maintain operational safety and prevents accidents in environments where heavy lifting equipment is used.
