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

The term "working load limit" (WLL) refers specifically to the maximum safe load that a piece of lifting equipment can handle without the risk of failure. This is a critical parameter defined by the manufacturer of the equipment, ensuring that the equipment remains safe and functional during operations. It takes into account various factors, including design, materials, and safety considerations. Understanding the WLL helps prevent accidents and failures by ensuring operators do not exceed the limits set for the equipment's safe operation.

The correct definition acknowledges that WLL is not merely a guideline but rather a standard that aims to maintain safety and integrity. It emphasizes the importance of adhering to these limits in practical applications, such as lifting heavy loads with cranes or other equipment.
