The working load limit of a chain is defined as what?

The working load limit (WLL) of a chain is defined as the maximum weight that the chain can safely support while being used in a particular application. This limit is crucial in ensuring safety during operations that involve lifting, pulling, or securing loads. Overloading a chain beyond its working load limit can lead to failure, which can pose serious risks to operators and surrounding individuals.

The determination of WLL considers factors such as chain material, dimensions, and construction quality. It is established by manufacturers to inform users how much weight can be reliably supported without compromising the integrity of the chain. Understanding and respecting the working load limit is essential to avoid accidents and ensure effective performance in rescue and recovery operations.
