A lifting sling is used with a lifting device or crane in order to lift effectively and safely. Slings usually consist of cable, chain, rope or webbing, and generally include metal devices such as hooks, shackles, links or rings. The different types of sling are appropriate for different applications according to their type, working load limit, length, and slinging mode.

= Types of sling =

=== Nylon ===

Nylon slings are strong, dense and flexible; they will stretch to approximately 6-8% of its length. Consideration should also be given to the fact that nylon absorbs liquid, and the strength can be affected.

=== Polyester ===

These are known as web slings or rigging slings because of their synthetic, web-like fabrication. Polyester differs from nylon in that its stretch is approximately 3%, and are safe for use where bleaching agents or acids are present.

=== Wire rope ===

These are categorised based on the number of wires in a strand and how many strands are wrapped around a core. The numbers of wires and strands influence the resistance to abrasion and flexibility of the sling. Flexibility and resistance to kinks is increased by the more wires there are, but also make it more liable to abrasion wear. The fewer wires there are will make it more resistant but reduce the lifting flexibility.

=== Chain ===

Chain slings are suited to more intense lifting operations and work environments. They are usually constructed from Grade 80 or 100 high strength alloy steel and can be designed and fitted to create custom sling assemblies for almost every kind of lift.

Chain slings should be stored in a dry and clean area to avoid against damage, rust and corrosion. They should be regularly inspected for defects, such as the following:

* Wear and stretching.
* Bent or twisted links.
* Ineffective safety catches.
* Cuts and nicks.
* Gouges.
* Heat discolouration and welding splatter.
