When using more than two slings, what key requirement ensures balanced lifting?

• A. Attach slings at random points.
• B. Place all slings on one side to tilt the load.
• C. Attach slings to a common lifting point or spreader with equal length legs and symmetrical angles.
• D. Ignore the center of gravity when placing slings.

Answer: (C)

Balanced lifting with more than two slings relies on creating a single, even line of action through the load’s center of gravity. When slings are attached to a common lifting point or spreader, and each leg has equal length with symmetrical angles, the load’s weight is shared evenly. The vertical components of all the sling tensions add up to support the weight, while the horizontal components cancel each other out, preventing tilt or sway. A spreader bar helps keep the sling connections apart so the forces stay balanced and the load remains stable.

Attaching slings at random points, or placing all slings on one side, disrupts this balance. It creates unequal tension, pushes the lift off-center, and can cause tipping or uncontrolled movement. Ignoring the center of gravity makes it unpredictable where the lift will pull, increasing the risk of the load rotating, slipping, or swinging.
