What is the rating for wire rope ladders anchors?

The rating for wire rope ladders anchors is typically 2480 lbs. This rating reflects the strength and reliability required for safety in theatre rigging applications, especially considering the dynamic loads that may be applied during use. Wire rope ladders are designed for vertical rescue and access, and the higher load rating ensures that they can support not only the weight of a person but also any additional forces that might be encountered, such as during movement or shifting.

Assessing the other options, 1550 lbs, 1000 lbs, and 30:1 do not accurately reflect the standardized ratings for wire rope ladder anchors. Specifying 30:1, for instance, refers to a safety factor rather than a load rating, indicating that the material can withstand loads that are 30 times greater than the load it will typically bear. While safety factors are crucial in rigging, they serve a different purpose than the anchor rating, which more directly informs users of the maximum load limit.
