In a rigging assembly, the capacity is governed by which component?

• A. The strongest component determines capacity.
• B. The weakest component determines capacity.
• C. The heaviest component determines capacity.
• D. The lightest component determines capacity.

Answer: (B)

Capacity in a rigging assembly is limited by the weakest component. Each piece has its own Safe Working Load (SWL) or Working Load Limit (WLL), and the load path is only as strong as its weakest link. As you apply more load, the part with the lowest rating reaches its limit first, setting the maximum safe load for the entire setup. If that weakest component is overloaded, it can fail and compromise the whole lift. So, the overall capacity is the minimum rating among the components in the load path, highlighting the importance of inspecting for wear, deformation, and compatibility, and ensuring the system is designed so no single part dictates an unsafe limit.
