What does WLL stand for in lifting operations?

• A. Working Load Limit
• B. Weight Load Level
• C. Welded Load Link
• D. Wide Load Limit

Answer: (A)

WLL stands for Working Load Limit, which is the maximum load that lifting gear and rigging components are rated to lift safely under normal use. This rating comes from testing, material strength, and a built-in safety margin so operations stay within safe limits and avoid deformation or failure. In practice, you must ensure the load does not exceed the smallest WLL among all components in the lifting setup, since that component will control the overall safe capacity. WLL is a safety-focused rating, not the breaking strength of the material, which would indicate when something actually fails under extreme conditions. The other terms given aren’t standard terms for this concept in lifting operations, so the correct interpretation is Working Load Limit.
