RATED CAPACITY In addition to protecting the main body of the sling from abrasion and other damage, the jacket prevents sunlight from penetrating the body and causing ultraviolet degradation of the polyester fibers. Dirt and grime are also kept away from the load-bearing core of the sling by the jacket. Because it is 100% polyester moisture absorption, rot and mildew are virtually non-existent.

Polyester offers good resistance to common industrial acids (except concentrated sulfuric acid) and hot bleaching solutions. Slings may be used in the presence of alcohol, dry cleaning solvent; hydrocarbons, halogenated hydrocarbons, ketones, crude oil, lubricating oil, soaps, detergents, seawater and weak alkalis, but should NOT be exposed to strong alkalis at elevated temperatures, and should never be used under temperatures conditions above 200 degrees F.

EFFECT OF ANGLE When slings are used at an angle (i.e. - two slings or one sling in a basket attached to only one crane hook), sling capacity is reduced. How much it is reduced depends on the degree of the angle. You can determine whether a sling will be rated high enough if you know the angle between the sling leg and the vertical. Once you know this angle, multiply the sling's rating by the appropriate factor in the table. This will give you the sling's reduced rating.

EFFECT OF ANGLE CHART

ANGLE ° FACTOR ANGLE ° FACTOR
0 1 40 0.766
5 0.9962 45 0.7071
10 0.9848 50 0.6428

SLING CAPACITY DECREASES AS THE ANGLE DECREASES
A sling capable of lifting 1,000 lbs. in a 0° vertical basket htich, can only lift 866 lbs. at a 30° angle at a 45° angle and 500 lbs. at 60° angle.

ENDLESS SINGLE PATH ROUND SLINGS
Unique Flexi-grip Sling construction produces outstanding handling and rigging characteristics. The sling body is exceptionally supple, conforms readily to uneven and oddly shaped loads during a lift. Additionally, the sling has a softness which provides a firm gripping action on e load, particularly when used as a choker. The 100% polyester construction also provides extremely low (3%) elongation at rated loading.

High-strength, low-stretch polyester fibers run continuously, peripherally in the Flexi-grip sling body to develop the lifting capacity designed into each model. A double-walled polyester fabric jacket is sewn permanently in place to contain and protect the load-bearing fibers.

EACH SLING BODY IS CONSTRUCTED OF AN ENDLESS LOOP OF POLYESTER FIBERS ENCASED IN A DOUBLE-LAYER WOVEN JACKET. In addition to protecting the main body of the sling from abrasion and other damage, the jacket prevents sunlight from penetrating the body and causing ultraviolet degradation of the polyester fibers. Dirt and grime are also kept away from the load-bearing core of the sling by the jacket. Because it is 100% polyester moisture absorption, rot and mildew are virtually non-existent.

Polyester offers good resistance to common industrial acids (except concentrated sulfuric acid) and hot bleaching solutions. Slings may be used in the presence of alcohol, dry cleaning solvent; hydrocarbons, halogenated hydrocarbons, ketones, crude oil, lubricating oil, soaps, detergents, seawater and weak alkalis, but should NOT be exposed to strong alkalis at elevated temperatures, and should never be used under temperatures conditions above 200 degrees F.

BUFFALO SLING - SAFETY INFORMATION 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.

INSPECTION - Remove slings from service if damage such as the following is visible:

  1. Cuts on face or at edge of webbing.
  2. Holes, tears, snags or crushed web.
  3. Excessive abrasive wear.
  4. Excessive pitting or corrosion, cracked, distorted or broken fittings.
  5. Broken or worn threads in the stitch patterns.
  6. Melting or charring of any part of the sling.
  7. Acid or caustic burns.
  8. Other visible damage which causes doubt as to the strength of the sling.

!!WARNING!! Failure to follow the care, use and inspection instructions could result in severe personal injury. Do not exceed rated capacities.

OPERATING PRACTICES - WARNING: Web-slings can be cut by contact with sharp or unprotected load edges. Padding must be used to protect the slings.

  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. Sharp edges in contact with slings should be padded.
  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 200 degrees 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.
