For a tandem load with eight sling legs, maximum sling leg length variation is?

• A. 8 inches
• B. 6 inches
• C. 4 inches
• D. 12 inches

Answer: (B)

The key idea here is keeping the load level by ensuring all sling legs share the load as evenly as possible. With eight legs in a tandem lift, small differences in leg length can still tilt the load or shift the center of gravity enough to overload some slings or cause unstable movement during the lift. A fixed tolerance for how much the legs can differ in length is set to limit that tilt and maintain predictable load geometry, even as slings stretch or settle. You balance the rigging by measuring each leg, shortening or lengthening as needed, and rechecking the load is level before lift. This approach keeps the load stable and the rigging within safe limits, which is why the selected tolerance is the best choice.
