What is the function of a spreader bar in rigging?

• A. To concentrate the load onto a single point.
• B. To distribute the load across multiple slings, reduce edge pressure, and improve stability by keeping slings from contacting the load directly.
• C. To make the lift faster.
• D. To replace the need for slings entirely.

Answer: (B)

Spreader bars spread the load across several lift points instead of concentrating it at one spot. By attaching multiple slings to the bar and then to the load, the weight is shared, which reduces the pressure on any single point and helps keep slings away from sharp edges. This arrangement improves stability and balance during the lift, especially for wide or irregularly shaped loads, making the operation safer and more controllable. It does not speed up the lift, nor does it replace slings; you still need slings and other rigging components.
