Which factors determine the sling's rated capacity?

• A. Size
• B. Configuration
• C. Size, configuration, and angles formed by the legs
• D. Material

Answer: (C)

Understanding sling rated capacity starts with how load is carried by the sling. The size of the sling sets its strength—the larger or higher‑tensile sling can resist more tension before it yields or fails. The way you rig the sling changes how the load is shared and where stresses concentrate; for example, a straight lift, a basket hitch, or multiple legs each distribute the force differently and can impose different demands on the sling and hook. The angles formed by the legs are critical because they determine how the load resolves into tension in each leg. With two legs, each leg carries a share of the load that grows as the legs move closer to vertical; as the legs spread wider, the tension per leg decreases but the overall setup changes how the load interacts with the sling and crane. In short, the sling’s rated capacity depends on size, configuration, and the angles formed by the legs.
