2 PROCRAFT WEB SLINGS INTRODUCTION Procraft synthetic webbing slings are generally manufactured from Nylon, but can also be manufactured from Polyester. The light weight of the material, combined with superior flexibility have made these slings popular with riggers over the years. Webbing slings will not scratch or deface loads and the webbing s flexibility will form a secure grip around the load to be lifted. Slings manufactured from Nylon will stretch between 6% to 8% and should be used if alkalis are present, while Polyester slings will stretch approxiametly 3% and should be used where acids exist. Synthetic webbing used to manufacture slings have a chemically treated surface to increase abrasion resistance, seal out moisture, and prevent grit from attacking the webbing internally. The webbing is unaffected by moisture, mildew, rot and certain chemicals. SLING MANUFACTURE Procraft web slings are manufactured to strict quality standards, and our constant in house testing and quality analysis of all materials and fabrication procedures ensure users a superior product. Slings can be manufactured in either single or multiple plies, and may include accessories such as wear pads, sleeves and end fittings. Several types and configurations are available. The following system is used to identify different types at time of order: Sling Type (2 letters) EE - Eye each end EN - Endless TC - Triangle & Choker TT - Triangle each end ER - Reverse eye each end Indicates the number of plies in sling. (1,2,3 or 4) Webbing material capacity. Webbing width in inches (1 to 12). WARNING: NEVER EXCEED WORKING LOAD LIMITS PAGE 2

3 TYPE 1: Triangle & Choker (TC) hardware on each end manufactured from either steel or lightweight aluminum. Most effective for choker hitch, can also be used in vertical or basket hitches. TYPE 2: Triangle & Triangle (TT) hardware on each end manufactured from either steel or lightweight aluminum. For use in either basket or vertical hitches only. TYPE 3: Flat Eye & Eye (EE) sewn on each end. Choice of either straight (easy to remove from underneath loads) or tapered eyes. For use in vertical, choker or basket hitches. TYPE 4: Twisted Eye & Eye (EE) sewn on each end. Eyes are turned at a right angle to sling body and choice of either straight or tapered eyes. Forms effective choker hitches, also used in vertical or basket hitches. TYPE 5: Endless Grommet slings (EN) sewn together to form an endless loop. Versatile sling for all hitches. Other Fittings: Slings can be manufactured with other steel fittings including Connectors, Shackles, Hooks and Couplers. Also available wear pads and protection sliding sleeves. Please contact Wesco Industries for further information on these products. WARNING: NEVER EXCEED WORKING LOAD LIMITS PAGE 3

4 ENVIRONMENTAL CONSIDERATIONS All slings should be stored in a cool, dry, and dark place away from harmful ultra-violet rays (sunlight) and Arc Welders in operation. Continuous exposure to sunlight can affect the strength of synthetic webbing in varying degrees, ranging from total degradation to slight degradation. Nylon and Polyester slings shall not be used with temperatures in excess of 194 degree F (90 degrees C). Chemical active environments can be hazardous to the sling strength, Wesco Industries should be consulted before using slings in such environments. See chart below for a guide on chemical resistance of webbing: NYLON NO YES YES YES NO YES YES YES YES YES YES YES YES YES YES POLYESTER # YES NO ## YES YES NO YES YES YES YES YES YES YES YES #Disintegrated by concentrated sulfuric acid. ## Degraded by strong alkalis at elevated temperatures. CARE, USE & INSPECTION Webbing slings should be inspected by the person(s) prior to any lifting operations. The inspector should seek to detect any surface damage to the sling and its components. Excessive surface chafe (wear), cross or longitudinal cuts in the webbing, cuts or chafe damage to the edges (caused by overloading), crystaliztion of the webbing (caused by exposure to excessive heat), local weakening or softening of the webbing material so that surface fibres can be plucked or rubbed off, corrosion and/or distortion of hardware - caused by acids or overload; will result in a serious loss of strength to the sling. A sling so affected should be taken out of service immediately. Never try to repair a damaged webbing sling. Wesco Industries can inspect and reuse your old webbing sling hardware safely and provide proof load certification if required. WARNING: NEVER EXCEED WORKING LOAD LIMITS PAGE 4

5 Once sling has been inspected, determine the weight of the load, type of load to be lifted and the sling angle that is to be used. Make sure that the sling will be protected from cuts by sharp edges, sharp corners and abrasive surfaces. NEVER EXCEED THE WORKING LOAD LIMIT OF THE SLING! SLING ANGLES When slings are used in a basket hitch and suspended from one hook sling angles will directly affect the rated capacity of any slings. The sling to load angle is the angle between the horizontal top of the load and the leg of the sling. As the sling to load angle decrease, so does the safe capacity of the sling. Refer to the charts below: Sling Angles in Degrees Factor Sling Angles in Degrees Factor Angles less than 45 degrees are not reccomended and those below 30 degrees should be avoided whenever possible.

9 POLYESTER ENDLESS SLINGS INTRODUCTION Wesco Industries endless synthetic slings are manufactured from a continuous loop of polyester yarn covered by a single herringbone weave jacket. The jacket is colour coded and protects the inner core of load bearing polyester yarns from damage and UV rays. Endless slings have many advantages including: Low stretch (about 3% at rated capacity). Excellent contact and conforms to shape of your load to grip securely. Cover will not scratch or damage your load surface. Light weight. Excellent for use in choke hitch applications as sling releases easily after use.
