Nylon Web and Polyester Sling Information

Web Material – Soft and Flexible

Web Slings are made from nylon or polymer lifting yarn that is woven into various widths and thicknesses. A tough abrasion resistant jacket yarn surrounds the lifting yarn.

Red Warning Core

Red colored yarns under the jacket show when the jacket is worn or cut through and indicates that the sling should be taken out of service.

Shock Absorption

The stretching of web slings allows a cushion against sudden shock. When loaded at rated capacity, a nylon sling will stretch 6-8% and polyester 3-4% Slings return to normal length when not loaded.

Use of Sling

1. Load Surface Problem: Protect sling from being cut by LOAD EDGES, CORNERS, PROTRUSIONS, and ABRASIVE SURFACES. Certain accessories available from Hanes Supply could help protect the sling.
2. Avoid Crushing and Knotting of Slings: Don't crush a sling between load and other surface.
3. Do not expose the sling to the sun for an extended period of time. Prolonged sun exposure of the sling will degrade lifting capacity.
4. Different Hitches' Rated Capacities: Slings have the largest load when used in the basket hitch. Capacity in the vertical hitch is 60% of that in the basket hitch. Capacity in the choker hitch is 40% of basket hitch capacity.

Inspection and care of Synthetic Web Slings Prior to use, make certain that each sling meets the requirements of your order and that it has not been damaged in delivery to you.

Operating Practices

1. Determine that the weight of the load is within the rated capacity of the sling.
2. Select sling having suitable characteristics for the type of load, hitch and environment.
3. Slings shall not be shortened or lengthened by knotting or other unapproved methods.
4. Damaged slings shall not be used.
5. Slings shall be hitched in a manner providing control of the load.
6. Protect sling form being cut by LOAD EDGES, CORNERS, PROTRUSIONS, and ABRASIVE SURFACES.
7. Keep all portions of the human body from between the sling and the load, and from between the sling and the lifting hook.
8. Personnel should stand clear of the suspended load.
9. Personnel shall not ride the sling.
10. Shock loading should be avoided.
11. Slings should not be pulled from under a load when the load is resting on the sling.
12. Slings should not be stored in an area where they will be subjected to mechanical damage, moisture, extreme heat or ultraviolet light.
13. Twisting of slings shall be avoided.
14. Loads applied to the hook should be centered in the base of the hook to prevent point loading on the hook.
15. Before lifting, make certain that the sling, attachments, or load shall not snag. Personnel shall be continuously alert to avoid snagging or bumping.
16. In a basket hitch, the lifting hook should be above the center of gravity and the load balance to prevent slippage out of the sling.
17. When making a multiple leg lift, the capacity rating of each sling must be downgraded in accordance with the Effect of Angle Chart.
18. Slings should not be dragged on the floor or over an abrasive surface.
19. In a choker hitch, slings with hardware shall be long enough so that the choker fitting chokes on the webbing and never on the triangle.
20. Nylon and polyester slings shall not be used at temperatures in excess of 194°F.
21. Exposure to sunlight or ultraviolet light degrades the strength of synthetic web slings.
22. Inspect slings for damage and defects prior to each use.

Additional requirements and safe operating practices are outlined in current OSHA and ANSI B30.9 regulations.

When ordering slings always consider the type of hitch, capacity tables and the sling-to-load angles.
