If you are using a four-leg bridle hitch, how do you calculate the load per OSHA guidelines?

• A. Divide by 4 legs
• B. Divide by 3 legs
• C. Divide by 2 legs
• D. Divide by 5 legs

Answer: (B)

When distributing load in a multi-leg sling, you use the number of legs that actually carry the load at the lifting point. In a four-leg bridle hitch, the geometry typically results in three legs sharing the vertical load rather than all four. One leg often doesn’t take on the load due to how the lines converge at the hook, so the per-leg load is the total weight divided by three. Dividing by four would overstate the load per leg, and dividing by two would apply to a two-leg sling, not a four-leg bridle. If the setup is perfectly balanced and the hook geometry changes, distribution could differ, but the standard practice reflected in OSHA guidance is to use three legs.
