What does the term "working load limit" (WLL) refer to?

The term "working load limit" (WLL) refers specifically to the maximum load that rigging equipment, such as ropes, slings, and connectors, can safely support in normal working conditions. It is a crucial safety parameter that ensures the rigging system is used without exceeding the capacity of the equipment, thus preventing accidents and failures.

Knowing the WLL helps riggers and operators determine how much weight can be safely lifted without risking the integrity of the rigging gear or the safety of personnel involved. This limit is determined by rigorous testing and is often marked on the equipment itself, making it easy for users to reference when planning lifts. Understanding the WLL is essential for effective and safe rigging practices in various environments, particularly where heavy loads are involved.
