What does WLL represent in rigging?

WLL stands for Working Load Limit, which is a critical safety consideration in rigging and lifting operations. This term designates the maximum load that a particular rigging setup, including slings, shackles, and other hardware, can safely handle without risking failure or compromising safety. It's essential for ensuring that the equipment is not overloaded and operates within its designed parameters.

Understanding WLL helps riggers make informed decisions when selecting equipment for lifting tasks. By adhering to WLL guidelines, they can prevent accidents and equipment failure, thereby maintaining a safe working environment. Using WLL also promotes compliance with safety regulations and industry standards, which is crucial in rigging practices.

The other terms provided do not represent established concepts within rigging, which further underscores why Working Load Limit is the correct answer.
