Slings are available in different sizes, different materials and different widths. You can buy slings in single, two, three and four leg form. Below are the different types of slings that are available.
Roundslings
Roundslings are an endless loop of yarn which are covered by a woven tubular jacket. One advantage to round slings is that all of the load-bearing yarns are protected by this jacket. Round slings use polyester load yarns that are protected by a double wall, polyester cover. Sizes larger than this use an abrasion-resistant nylon, double wall jacket. All round sling jackets are color-coded along industry standards to indicate their capacity rating. While the standard configuration is endless, they are also available in eye & eye and braided styles.
Most roundslings have high strength, Aramid fibers for their load bearing yarns. These slings are the strongest and lightest slings in the world, with the lowest sling weight per capacity rating. Orange colored, double wall jackets for all sizes indicate that these slings have Aramid load bearing yarns. Tuff-Tags are standard on these, and all synthetic slings.
Wire Rope Slings
Wire Rope Slings are mainly found at construction sites because of their low cost and resistance to abrasion in construction work environments. High tensile strength steel wires are combined in various constructions to form ropes with specific characteristics. Standard constructions for slings are referred to as 6X19 or 6X36, designating the total number of wires being used. The greater the number of wires, the greater the flexibility and the lower the resistance to abrasion. Typical sling ropes use 6X19 in the smaller diameters and 6X37 at 1 ¼” diameter and larger.
Eye & Eye style slings are the most popular, but numerous end fittings are available to suit specific needs.
Chain Slings
The most appropriate type of sling that is used in extreme conditions where a normal sling would not last. Typical environment would be foundries and steel mills. Material used in chain slings is typically high strength alloy specific for the lifting industry.
