Which term describes the maximum tension a rigging component may endure while maintaining a safety margin?

The term that accurately describes the maximum tension a rigging component may endure while maintaining a safety margin is the working load limit (WLL). The WLL is defined as the maximum weight that a rigging component can safely handle in normal operations, taking into account a safety factor. This factor is designed to prevent accidental failure under normal conditions of use.

The rated load, while similar, generally refers to the maximum weight that can be supported without considering safety practices necessary in operational settings. Breaking load defines the point at which a component will fail, while ultimate load usually indicates the maximum load a material can withstand before structural failure occurs, also without a safety factor applied.

Therefore, the working load limit is the most accurate term when discussing operational safety and allowable loads in rigging contexts.
