For a single-point load with six sling legs, maximum sling leg length variation is?

• A. 12 inches
• B. 6 inches
• C. 9 inches
• D. 15 inches

Answer: (A)

Balancing load across all sling legs in a single-point lift is essential to keep the load centered and prevent tilting or uneven tension. With six legs, keeping the lengths within a fixed tolerance ensures the lift point stays near the load’s center of gravity and each leg shares the load more evenly. The accepted tolerance is twelve inches; the difference between the longest and shortest leg cannot exceed this. Staying within this limit helps prevent a single leg from carrying most of the load as you lift, which could cause dangerous side loading on hardware and destabilize the rig. If setup would exceed this tolerance, reconfigure the legs or adjust lengths before raising to maintain balance. This value is chosen to balance practicality with safety for common six-leg configurations.
