Web slings are lightweight, flexible and have wide bearing surfaces to help protect the load. They are the most popular type of sling and can be found in the maintenance department of every manufacturing environment. Their stretch characteristics help to avoid shock loading problems. Lift-All® offers many web grades, styles and sling configurations to suit various industry needs. Our sling webbing is available in nylon and polyester, and all sling webbing contains red core yarns to aid in the inspection process. Lift-All web brands include Tuff-Edge® II, Webmaster® 1600, Webmaster® 1200 and Dura Web.
Roundslings are an endless loop of yarns covered by a woven tubular jacket. One advantage to round slings is that all of the load-bearing yarns are protected by this jacket. Lift-All Tuflex® round slings use polyester load yarns that are protected by a double wall, polyester cover for sizes EN30- EN240. Sizes larger than this use an abrasion-resistant nylon, double wall jacket. All Tuflex® round slings 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.
KeyFlex 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. KeyFlex standard sizes range from 10,000 to 200,000 lbs. vertical rated capacities.
Wire Rope Slings are popular at construction sites because of their low cost and resistance to abrasion in rugged 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. Lift-All Permaloc wire rope slings use a Flemish Eye Splice to form the sling eyes. This method provides an additional measure of safety over the Return Eye style, should the steel sleeve used to form the eye become damaged.
Chain Slings are preferred for use in the most rugged conditions, where other slings would not survive. Steel mills and foundries are typical users of chain slings. Chain slings are made from high strength alloy steel made specifically for the lifting industry. They have numerous configurations and end fittings, which can be connected with a welded link for permanent attachment, or a mechanical link when welded is not available.
Standard slings are available in two grades of steel: Grade 80, which is the industry standard, and Grade 100. Chain slings are the most rugged slings available. They are resistant to both abrasion and cutting and may be used at temperatures up to 400°F (204˚C) without reducing capacity rating. Grade 100 slings are 25% stronger per chain diameter than Grade 80.
Wire Mesh Slings are specialty slings with limited applications. Machine shops and steel warehouses where they handle lengths of bar or round stock are good applications.
High tensile steel wire is formed into spirals and connected together with straight pins and brazing. Alloy steel triangle and choker fittings are connected to either end.
A wide bearing surface helps to protect and balance the load. Single plane flexibility allows for tight choker hitches. Wire mesh slings may be used in temperatures up to 550°F (260°C).
Chain Mesh Slings excel in rugged applications, and are widely used in metalworking shops and stevedoring where abrasive conditions or hot environments damage and destroy synthetic slings.
The number one cause of synthetic sling failure is cutting. When slings are cut, property damage and personal injury or death can result. Wear pads can help to reduce this problem by acting as a buffer between the load edge and the sling. Used with steel slings, wear pads help protect both sling and load from damage along points of contact.
