How is the working load limit of rigging equipment determined?

The working load limit (WLL) of rigging equipment is determined by dividing the breaking strength by a safety factor. This calculation is essential in ensuring the safety and reliability of the rigging setup. The breaking strength refers to the maximum load that the rigging gear can tolerate before failing, while the safety factor is a predetermined ratio that accounts for potential variables and uncertainties, such as dynamic loads, wear and tear, and the conditions under which the rigging is used.

Using this method allows for a conservative estimate of the maximum load that the rigging can handle safely during operations, minimizing the risk of accidents or equipment failure. It ensures that even under the worst-case scenarios, the rigging will perform adequately and safely. This approach is foundational in rigging practices, aligning with industry standards for safety and operational integrity.
