Synthetic Sling Questions
Q: What is the difference between nylon and polyester web slings?
A: The differences are usually not a factor in most sling applications. At rated capacity, a treated nylon sling stretches approximately 10%, whereas a treated polyester sling will stretch approximately 7%. Nylon’s extra stretch helps to avoid shock loading. The lesser stretch of polyester makes load control easier by reducing bounce. In a chemical environment, nylon should not be used around acids or bleaching agents while polyester should not be used near aldehydes.
Q: What is the D/d for Web Slings?
A: There is no industry standard for D/d and web slings. Should you have a specific application that you question, the Lift-All® Customer Service Department would be happy to review it with you: customerservice@lift-all.com or 800-909-1964.
Q: Can I use my web slings in oil, water and solvents without affecting their safety?
A: Water has no significant affect on the strength of web slings. For questions on specific chemicals, please contact the Lift-All Customer Service Department for assistance: customerservice@lift-all.com or 800-909-1964.
Q: Does dirt and grease affect the strength or shorten the life of synthetics slings?
A: Dirt in a web sling can promote internal abrasion that can reduce sling strength and possibly shorten sling life.
Q: Is it O.K. to wash my nylon sling and what can I wash it with?
A: Cleaning of synthetic slings is addressed in our technical bulletin: G-31 Clean r1-07
Q: What is the capacity difference between the Tuff Edge II and the standard webbing?
A: Most web slings fall into two categories based on web strength. The heavier duty webbing is rated at 1600 lbs. per inch of width, and the lighter duty webbing is rated at 1200 lbs. per inch of width. Our Tuff-Edge II webbing is in the heavier-duty 1600 lb. class.
Q: Will you retag synthetic slings that are not defective, but that have a missing or unreadable tag?
A: A sling that can be identified as a Lift-All sling can be retagged if it otherwise passes inspection.
Q: Is it O.K. to use synthetic slings over a forklift fork?
A: Unprotected slings should not be used since the forks will tend to cut slings under load. Hooks for attachment to forklift forks are designed specifically for this purpose. For more information: Single Fork Hooks
Q: Why is the body two-ply, but the eye isn’t?
A: Since the eye is essentially a basket hitch in itself, there is no need for a two-ply eye on a two-ply sling.
