In lifting operations, reducing the sling angle requires reevaluating the load because the rated capacity does what?

• A. Increases
• B. Decreases
• C. Stays the same
• D. Varies with load

Answer: (B)

When lifting with slings, how the load is shared depends on the angle at the load. The sling rating is tied to a specific angle; as you bring the legs closer together (reduce the sling angle), the tension in each leg must increase to hold the same weight. Since the rigging is rated for a certain tension, increasing the required tension effectively lowers the system’s safe capacity. That’s why reducing the sling angle means you must reevaluate the load—the rated capacity decreases. If the angle can’t be kept wide enough, you’d need more slings, a spreader, or a different rigging arrangement to stay within safe limits.
