WLL stands for the “working load limit,” and SWL stands for “safe working load.” These are terms commonly found in the field of engineering. The main difference between safe working load from the working load limit is that SWL is the archaic term, which is no longer valid. SWL is not used anymore, as it has been entirely replaced by WLL. Safe working load is the quantity of weight that a lifting device can carry without fear of breaking. The lifting equipment maximum breaking strength is divided with the safety factor of equipment ranges from 4 to 6. If the equipment presents a risk to an individual’s life, the safety factor is raised to 10. United States standards ceased their use of SWL. They needed a more appropriate term. So, WLL was established.
