Every lift presents a unique set of challenges that demands the right equipment to ensure safety and efficiency. Using the incorrect rigging gear can damage your load or put your crew at risk. You need to understand the specific strengths and limitations of the various lifting slings available on the market today. Paducah Rigging provides the industry expertise you need to match your hardware to the specific demands of your worksite.
Understanding Different Types of Slings
The environment of your lift and the nature of the load determine which sling you should use. Different materials offer varying levels of resistance to heat, abrasion, and shock.
- Wire Rope Slings: These are a standard choice for construction and heavy industrial environments. They offer excellent abrasion resistance and are durable enough to withstand rough handling. Wire rope slings vary in flexibility based on their construction but generally provide a cost-effective solution for rugged conditions.
- Alloy Chain Slings: If your application involves high temperatures or requires extreme durability against cuts and abrasion, chain slings are the superior option. They are adjustable and repairable, which makes them a long-term investment for foundries and steel mills.
- Synthetic Web Slings: These are lightweight and flexible. They are ideal for lifting delicate or finished parts that must not be scratched or crushed. Nylon and polyester options provide different resistance profiles to acidic or alkaline environments.
- Round Slings: Constructed with load-bearing yarns inside a protective jacket, these offer immense lifting capacity in a lightweight package. They contour easily to the load and are colour-coded for quick capacity identification.

Wire Rope vs. Synthetic Slings
Deciding between wire rope or synthetic slings often comes down to the balance between durability and load protection. Wire rope is the preferred choice when the sling will be exposed to rough edges or abrasive surfaces that would easily cut a fabric strap. It is tough and predictable.
Synthetic slings, on the other hand, are the better choice when you need to protect the load itself. They are soft and pliable, which allows them to grip the load tightly without marring the surface. They are also significantly lighter than wire rope or chain, which reduces rigger fatigue and speeds up the setup process. However, you must be vigilant about protecting them from sharp edges and corners.
Know When to Stop: Sling Removal Criteria
Even the highest quality gear eventually wears out. Inspecting your equipment before every shift is a mandatory safety practice. You must remove a sling from service immediately if it meets specific OSHA or ASME rejection standards.
The sling removal from service criteria include:
- Missing or Illegible Identification: If you cannot read the tag to verify the rated load, you cannot use the sling.
- Acid or Caustic Burns: Look for discoloration or deterioration of the fibers or metal.
- Heat Damage: Melting, charring, or weld splatter on synthetic materials is grounds for immediate removal.
- Broken Wires: For wire rope, a specific number of broken wires in a lay or strand requires the sling to be retired.
- Cuts and Snags: Any edge cut or significant abrasion on a synthetic sling compromises its strength.
- Distorted Fittings: Hooks, links, or eyes that are bent, twisted, or stretched indicate the hardware has been overloaded.
