5/8" PROLINE12™ UHMPE Adjustable Rope Slings - Double Leg

PROLINE12™ UHMPE Adjustable Rope Slings replace multiple, “non-adjustable” slings by accommodating a range of dimensional requirements with infinite adjustability. Available in single, double, three and four leg configurations, PROLINE12™ UHMPE Adjustable Rope Slings are made from single braid, twelve strand, low elongation high performance synthetic rope. Stock lengths are shown below, however custom lengths and adjustment ranges are readily available.

UHMPE Adjustable Rope Slings provide higher Work Load Limits than standard, polyester adjustable rope slings. PROLINE12™ PROLINE12™ UHMPE Adjustable Rope Slings are treated with a coating to enhance abrasion and UV degradation resistance.

Lift-It® PROLINE12™ UHMPE Adjustable Rope Slings feature wear protection sleeves in the lift and connection eyes.

PROLINE12™ UHMPE Adjustable Rope Slings are labeled with the information currently required by the various regulatory agencies. Please review the User Guide that accompanies each PROLINE12™ UHMPE Adjustable Rope Sling for information on proper use and inspection. 

Considerations for Lift-It® PROLINE12™ UHMPE Rope Slings

• During use in basket hitches, ANY CONTACT with Adjustable UHMPE Rope Slings must be on the ROPE BODY between the Fixed Eye splice and Tuck & Bury Region.
• During use, NEVER allow the Tuck & Bury Region, also known as the Adjustable Splice, to contact the load and/or connection/suspension points.
• During use, The Handle must NEVER contact the Exit Point of the Tuck & Bury Region.
• During use, the Free Rope must extend a MINIMUM of 6 inches from the Exit Point.
• Slings shall not be shortened or lengthened by knotting or twisting and/or be joined by knotting. Twisting and kinking MUST be avoided. 
• Twists MUST be removed before applying tension. 

 

UHMPE Adjustable Rope Sling basket hitch Work Load Limits are significantly affected by the D/d ratio between the load Diameter and the nominal rope diameter. WLL must be reduced if less than a 25:1 D/d     UHMPE BASKET D/d REDUCTIONS D/d Basket Efficiency Factors 25:1 100% 8:1 82% 5:1 80% 3:1 75% 2:1 72% 1:1 65%

Lift-It® Three and Four Leg PROLINE12™ UHMPE Adjustable Rope Slings feature a Top Lifting Link. Depending upon your selection, based on Work Load, you must determine whether a Masterlink or Masterlink with Subassemblies makes the most sense from a fitting weight perspective. With either option, heavy duty thimbles are attached at the connection points to the Top Lifting Link.

PROLINE12™ UHMPE Adjustable Rope Slings with Top Lifting Links feature hardware that is not only based on the WLL, but also the correct size. We take into account not only the strength requirements, but the spatial relationship between sling attachment points and interfacing hardware.

Generally, Lift-It® Bridle Assembly capacities are lower than our competitors. Three leg capacities are based on 2-1/2 legs, while Four Leg Bridle Assembly capacities are based on three legs carrying the assigned capacity.

Lower capacities and more expensive, larger hardware will never allow us to be the successful, low bidder. Our conservative approach is respected by conscientious users and appreciated by sophisticated purchasers. In this instance, spending more for less provides for increased safety and longer sling service.

Lifts can be made with any two or three legs of the four leg, PROLINE12™ UHMPE Adjustable Rope Sling, if it has a Master Link or Master Link with subassemblies. If three of the four legs are used, the assembly Work Load Limit must be reduced by 33% and is effectively the same as the rating for a two leg (double) sling.
