What is the purpose of using a spreader or lifting beam in rigging?

• A. To distribute load and maintain proper sling angles, reducing side load.
• B. To clamp the load to the hook.
• C. To shorten sling length.
• D. To replace the need for rigging hardware.

Answer: (A)

Spreader bars and lifting beams are used to distribute the load across multiple slings and keep them at proper angles. By spreading the load, each sling carries a portion of the weight and the sling angles stay wide enough to minimize side load on the slings and the hook. This reduces peak tension, improves stability, and prevents excessive wear or failure of rigging components, especially for long or bulky loads. It also helps control load balance and reduces the risk of tipping. They don’t clamp the load to the hook, don’t shorten sling length, and don’t replace rigging hardware.
