When is a spreader bar used in rigging?

• A. To distribute load to multiple points, reduce sling angle, and keep the load stable and aligned.
• B. To increase the single point load.
• C. To replace the need for a crane.
• D. To hold the rope.

Answer: (A)

A spreader bar is used to distribute the load across multiple lift points, helping to keep the load stable and aligned. By attaching several lifting slings to the bar, the weight is shared, which reduces the stress on any single sling and maintains a favorable lift geometry. It also keeps sling angles closer to vertical, which lowers tension and minimizes sideways forces that can cause the load to tip, bind, or shift during lifting. This makes it ideal for wide or irregularly shaped items where a single point would be unsafe or ineffective. It isn’t meant to increase a single point load, replace the crane, or hold the rope, which is why the other options aren’t appropriate.
