What does WLL stand for in rigging terms?

WLL stands for Working Load Limit in rigging terms. This term refers to the maximum load that a piece of rigging equipment, such as a hoist, strap, or other lifting devices, is rated to support safely. Understanding WLL is crucial for ensuring the safety and integrity of rigging operations, as exceeding this limit can lead to equipment failure, accidents, and potential harm to personnel and surrounding structures.

The concept of Working Load Limit is derived from the need to establish safe operational parameters for lifting and rigging tasks. Each piece of equipment will have specific guidelines provided by the manufacturer regarding its WLL, which is determined through rigorous testing and evaluation. Therefore, always referring to these limits is essential for safe lifting practices.
