What does WLL stand for?

• A. Winding Load Limit
• B. Weight Load Limit
• C. Working Load Level
• D. Working Load Limit

Answer: (D)

WLL stands for Working Load Limit. This term communicates the maximum load a lifting component is approved to safely carry during normal operation. It’s set by the manufacturer based on testing and includes a safety margin relative to the component’s strength, so you know not to exceed it in use. The other phrases don’t match how these ratings are named in practice—Winding Load Limit isn’t a standard term for rigging ratings, Weight Load Limit isn’t the conventional label, and Working Load Level isn’t used. So the established, widely used designation is Working Load Limit.
