SYNTHETIC SLINGS
The Liftex commitment to superior products and service has positioned us as an industry leader. We manufacture a complete line of synthetic lifting slings. From our Pro Edge flat web slings, our Roundup Round slings, to our Pac Flex alloy chain mesh slings, we will provide a superior solution for all of your lifting or moving needs.

Nylon & Polyester Sling Features:
  • Load Protection: Will not mar, deface, or scratch the most highly polished metal surface and are equally gentle to non-metallic loads.
  • Strength: Tensile strength is outstanding. Will handle loads as great as 300,000 lbs or more.
  • Convenience: Lightweight and extremely flexible; they are easily and quickly handled and adjusted to the load.
  • Varied webbing widths: With widths from 1" to 24" (or even wider) there is a synthetic webbing sling that is wide enough to balance the load that needs to be lifted.
  • Safety: Adjusts to load contour and holds it with a tight, non-slip grip. Load bearing inner fibers are completely covered and protected by abrasion by a tough strong outer woven cover. Non- sparking.
  • Long Life: Unaffected by mildew, rot, or bacteria, and have excellent abrasion resistance. All Liftex slings, whether in Nylon or Polyester, are treated to seal out moisture and dirt, and to reduce the effects of abrasion.
  • Economy: Low initial cost plus long service life.
  • Shock Absorbent: Synthetic webbing slings have elongation characteristics which minimize the effects of shock loading. All loads are cushioned with minimum jarring.
  • Indication Core: All flat web slings have RED indicator core yarns to help assist in determining sling wear or damage. If these red core yarns are visible the slings should be pulled from service. (WARNING: A sling may still need to be pulled from service even if the red core yarns are not visible. In some applications slings may become very dirty making the red yarns not as visible. Also even if the red core yarns are not visible there could still be damage in other areas of the sling. All slings should be carefully inspected before every use.)
Nylon & Polyester Performance Characteristics
Nylon:
  • Unaffected by grease or oil
  • Good chemical resistance *
  • Not to be used in acids or bleaching agents
  • May be used in many alkalis but is subject to degradation ranging from none to moderate
  • Not suitable for use at a temperature exceeding 194°F
  • Elongation approximately 10% at rated capacity
Polyester:
  • Unaffected by grease or oil
  • Good chemical and acid resistance *
  • Not to be used in concentrated sulfuric acid
  • Not suitable for use at a temperature exceeding 194°F
  • Elongation approximately 3% at rated capacity
* Chemically Active Environments can effect the strength of webbing slings in varying degrees, ranging from none to total degradation. Each application must be evaluated and take into consideration the following:
  • Type of acid, alkali or other material
  • Exposure conditions
  • Concentration
  • Temperature
Before ordering slings that are going to be used in a chemically active environment, contact Liftex Customer Service, to recommend the right sling for the right usage.
Factors Effecting Performance of Web Slings:
Edges: All synthetic webbing slings are subject to cutting when lifting items with Edges. Edges that come in contact with the sling should be padded with material of sufficient strength to prevent damage to the sling. Wear pads give extra protection to the sling where the most wear occurs. Please refer to our page on wear pads and sleeves for all of your options.

Ultra-Violet Exposure: Environments in which synthetic webbing slings are continuously exposed to ultra-violet light can effect the strength of synthetic webbing slings in varying degrees from slight to toal degradation.
  • Suggested procedures to minimize the effects of ultra-violet light - sunlight or arc welding flash.
    • Store slings in a cool, dry and dark place when not being used for prolonged periods of time.
    • Inspect slings weekly or even more frequently depending on sling use.
  • Visual indications of ultra-violet degradation are:
    • Bleaching out of sling color
    • Increased stiffness of sling material
    • Surface abrasion in areas not normally in contact with the load
  • Proof-testing:
    • Slings used in environments where they are subject to continuous exposure to ultra-violet light should be proof tested to two times rated capacity annually, or more frequently depending on severity of exposure
Sling Stresses at Different Angles: When selecting a sling to carry a given load, it is important to consider the angle at which the sling will be used. As an example, one sling in a basket hitch or two slings attached to one crane hook are different applications involving different sling angles. The degree of the angle will determine how much capacity will be reduced. To determine if a particular sling will have the capacity required, take the angle between the sling leg and the horizontal, then multiply the slings's rating by the factor provided in the accompanying table.
Angles in Degress Factor
90 1000
85 0.996
80 0.985
75 0.966
70 0.940
65 0.906
60 0.866
55 0.819
50 0.766
45 0.707
40 0.643
35 0.574
30 0.500

The capacity of a sling will be reduced as the angle from horizontal is reduce. In the example below, you will see how the 1,000 lb capacity of a sling used in a vertical basket is reduced.



Sling Hitches
Slings carry their loads in any of one of four different hitches as illustrated. Most slings can be used with any of these hitches, but some are specifically designed for use in one hitch only.
