Never exceed the Working Load Limit (WLL) marked on the label of the lifting sling. This is the primary and absolutely non-negotiable core principle in the use of lifting slings. The WLL is a safety threshold determined by manufacturers through rigorous material testing, mechanical experiments, and scenario simulations, with sufficient safety margins reserved to cope with load fluctuations during normal operations.
When the load exceeds the bearing limit of the fibers, the fibers of the lifting sling will rapidly transition from elastic deformation to plastic deformation, and eventually break. More dangerously, the breakage caused by overloading is often sudden-it may occur without warning during the hoisting process, leading to serious accidents such as heavy object falling, equipment damage, and even casualties. According to the statistics of hoisting safety accidents, more than 40% of lifting sling breakage accidents are directly related to overloading.
