What is the term for the maximum load a rope assembly can safely handle under standard conditions?

Explanation:
The maximum load a rope assembly can safely handle under normal use is the working load limit. This value represents the safe operating limit with an appropriate safety margin applied to the rope’s strength, accounting for factors like wear, knots, and potential dynamic or shock loads. It’s not the rope’s ultimate breaking strength, which is higher; the WLL deliberately stays below that to prevent failure during routine use. Other terms like load capacity or safe load aren’t the standard designation used in rigging, and rated load isn’t the formal term for rope assemblies in this context. So the correct term is working load limit.
