What is a sling load, and when is it used in heavy rescue?

• A. A suspended load attached by slings for lifting heavy, awkward objects; requires proper rigging, anchor, and control
• B. A fixed weight attached to a crane
• C. A type of rigid beam used for bridging
• D. A rope-lowering technique without equipment

Answer: (A)

A sling load refers to a suspended load secured with slings so it can be lifted off the ground and moved, usually by a crane, hoist, or helicopter, with the weight distributed and controlled. This method is used in heavy rescue when the object is too heavy, awkward, or irregularly shaped to lift directly, because slings create a safer lift point and allow the operator to control and balance the load during the maneuver. The effectiveness of a sling load depends on proper rigging, a solid anchor system, and active load control. Rigging means selecting appropriate slings, protecting sharp edges, and ensuring the load is evenly supported to prevent slip or imbalance. Anchors must be capable and positioned to keep the load stable, with redundancy as needed. Control involves slow, planned lifts, use of tag lines to steer the load, clear communication, and maintaining safe distances from the lift. This is why the description that emphasizes a suspended load attached by slings for lifting heavy, awkward objects—and the need for proper rigging, anchor, and control—is the best fit for how sling loads are used in heavy rescue.
