What does WLL stand for in rigging terminology?

WLL stands for Working Load Limit in rigging terminology. This term defines the maximum load that a rigging component, such as a sling, shackle, or other lifting equipment, is designed to safely support during lift operations. Understanding the WLL is critical for safe rigging practices, as exceeding this limit can lead to equipment failure, accidents, and potential injuries.

Using the appropriate WLL ensures that the rigging setup remains within safe operational parameters, which is essential for maintaining safety standards on the job site. Every rigging component should have its WLL clearly marked or documented, allowing riggers to make informed decisions regarding load handling and equipment selection.

The other options do not accurately reflect the terminology recognized in rigging, highlighting a need for familiarity with industry standards and practices.
