    Twin-Path Considerations

    Twin-Path Considerations

    TREMENDOUS SAVINGS: Time is money and the ease of handling ultra-light, Twin-Path® Extra Slings adds up to substantial, cumulative savings. TUFXKS 7000 x 35 ft. weighs a mere 49 Lbs. and is rated at 140,000 Lbs. Basket WLL. A wire rope sling of equal length and strength weighs 588 Lbs. Extra cranes, forklifts, transport vehicles and personnel are no longer required for Twin-Path® Extra Slings. They have documented savings and prove to be the least expensive sling you will buy and use.


    USER FRIENDLY: Twin-Path® Extra Slings are easy to handle and will not “choke lock”, inhibiting sling removal from the load. Lightweight, Twin-Path® Extra Slings help eliminate typical and prevalent back, hand, foot and head injuries when using heavy, awkward, cumbersome wire rope and chain slings.


    LOAD FRIENDLY: Twin-Path® Slings provide load protection and will not mar, scratch or deface the most delicate metallic surface. Twin-Path® Slings are equally gentle on non-metallic loads.


    LOW ELONGATION: A Twin-Path® Extra Sling (TUFXKS 11000 x 328 in.), with High Performance, K-Spec® Core Yarn was vertically proof tested to 220,000 Lbs. After ten minutes, total elongation of 2 inches was recorded. Low elongation extends sling longevity as scraping over load surfaces is minimized.


    PULLING AND TOWING:
    Destruction testing demonstrates that Twin-Path® Extra Slings, featuring K-Spec® Core Yarn recoil very little at break. High modulus, low stretch materials eliminate most of the devastating whiplash effects, characteristic of chain, wire rope, nylon and polyester slings.

     

    Never use a sling for lifting after use in a towing or recovery operation. Never use a vehicle or tow strap for lifting after use in a towing or recovery operation.

     

    SUPERIOR ABRASION RESISTANCE: Twin-Path® Slings feature polyester or Covermax® covers. Seamless, Covermax® covers are specifically woven to provide abrasion resistance and are approximately four times more abrasion resistant than polyester covers.


    MATCHED SLING LENGTHS: Twin-Path® Extra Slings are made to matched lengths on a consistent basis. The accuracy of our products is unparalleled.


    SPACE SAVER: Storage problems are easily resolved as Twin-Path® Extra Slings require substantially less space than bulky, cumbersome wire rope and chain slings.


    ENVIRONMENTALLY SENSITIVE: Twin-Path® Slings do not require lubrication and will not corrode, thereby eliminating the harmful release of chemical agents or by-products. Twin-Path® Slings with Covermax® covers are more resistant to UV degradation than unprotected slings or slings equipped with covers that are not genuine Covermax® covers. Twin-Path® Slings do not lose strength when wet.


    CYCLIC TESTING
    : Repeated, vertical, fatigue testing was performed on Twin-Path® Extra Slings with K-Spec® Core Yarn. After 50,000 cycles to 150% Work Load, the independent test facility confirmed an 85 % retention of the original tensile strength. Twin-Path® Extra Slings with Covermax® covers will outlast and outperform other synthetic and wire rope slings.


    REPAIRABILITY:
    The abrasion resistance of Covermax® covers facilitates repair to Twin-Path® Slings, when Core Yarns are not damaged. Slings that appeared to be extremely distressed have been successfully repaired for a fraction of the original price. Trained, factory professionals carefully inspect every area of damage. If Core Yarns are undamaged, covers are repaired and the sling is proof tested to 200% Work Load. When abrasion resistance and longevity are considerations and when only the best is good enough, choose Twin-Path® Extra Slings with Covermax® covers.


    EXPOSURE TEMPERATURES: Twin-Path® Slings should not be exposed to temperatures above 180°F/82°C or below -40°F/-40°C. Twin-Path® Sparkeater® Slings should not be exposed to temperatures above 300°F/149°C or below -40°F/-40°C.


    COLD WEATHER EXPOSURE: Twin-Path® Extra Slings with K-Spec® Core Yarns have been used successfully in Northern Canada and Alaska for many years, without incident. The same yarn components used in K-Spec® Core Yarn are also used in deep space exploration applications. Twin-Path® Extra Slings with K-Spec® Core Yarns are a viable alternative for cold weather applications.


    LOAD MANIPULATION: When Twin-Path® Slings are used to change the orientation of an object, from a vertical to horizontal attitude, or vice versa, the cross over point on the sling paths, becomes a “hinge” point. Even Covermax® covers will become damaged at the “hinge” point. If Core Yarns become visible, do not use the sling. Remove it from service for repair evaluation.

     

    TATTLE TAILS: Twin-Path® Extra Slings have been extensively used and tested in all possible hitch configurations. In normal use, tattle tails perform as expected. When slings are used as load manipulators, i.e., used to turn or rotate loads, tattle tales will malfunction. The malfunction results from the difference in the external friction between the sling cover material and the manipulated object and the internal friction between the Core Yarns and sling cover material. Simply stated, the sling cover renders to the load, while the load carrying yarns rotate within the sling cover.


    PATH ORIENTATION: Twin-Path® Slings feature two paths that must be kept side by side. Folding one path on top of the other produces differential path lengths. The top path will see more tension than the lower path. In this scenario, sling Work Load Limits are reduced by 50%. It is also extremely important to load both paths of Twin-Path® Slings equally. DO NOT side load or edge load Twin-Path® Slings. When placing multiple slings into a lifting fixture, DO NOT “stair step” paths partially over each other. Place the paths directly on top of each other. Ensure the TAG PATCH portion of the sling is above the load and below the lifting fixture.
