There Are Three Different Types of Slings. What Determines Which Type You Use?

The answer

When choosing among the three common sling types — synthetic (web or round), wire rope, and chain — the selection is governed by the load itself and the environmental/working conditions. In practice you evaluate the load's weight, size, shape, and surface, then the environment it will be lifted in (temperature, chemicals, sharp edges, abrasion). The sling you pick must safely handle the weight, protect the load's surface, and survive the conditions without failing.

So the correct answer is not a single property but the combination: the type of load and the conditions under which the lift is performed decide which sling is appropriate. A delicate finished surface, a heavy jagged casting, and a lift near a furnace all call for different slings even at similar weights.

Why the other options are wrong

Exam distractors usually offer one factor in isolation:

• "Only the weight of the load" — Weight sets the required working load limit, but weight alone does not tell you whether heat, chemicals, or sharp edges will destroy a synthetic sling. Two loads of equal weight can require different slings.
• "Whatever sling is available" — Convenience is never the deciding factor. Using the wrong sling type is a serious safety violation.
• "The color of the sling" — Color codes can indicate capacity on some synthetic slings, but the choice is driven by load and conditions, not color.
• "The height of the lift" — Lift height affects rigging geometry and angle, not the fundamental sling material.

Only the answer that combines load characteristics with environmental conditions captures the full basis for selection.

The bigger picture

Each sling type has a niche defined by exactly those load-and-condition factors:

• Synthetic slings (nylon or polyester web/round) are lightweight, flexible, and gentle on finished or fragile surfaces. They resist many chemicals but are vulnerable to cuts, abrasion, and high heat — generally rated only up to roughly 180-200°F.
• Wire rope slings handle heavy loads, resist abrasion and higher temperatures than synthetics, and offer good strength-to-weight, but they can mar soft surfaces and are less flexible.
• Chain slings are the most rugged: best for very heavy, hot, or rough loads (foundries, steel mills) and highly resistant to heat, abrasion, and sharp edges. They are heavy and less gentle on delicate surfaces.

Regardless of type, safe rigging always includes checking the working load limit (WLL), accounting for the sling angle (smaller angles multiply tension dramatically), protecting against sharp edges with softeners, and inspecting the sling before every use for cuts, wear, broken wires, or deformed links. The core OSHA principle: never exceed the rated capacity, and always match the sling to both the load and the environment.
