Three-Leg Bridle Sling with Oval Link and Hooks

Three-part wire rope slings provide an exceptionally stable lift on large and awkwardly-shaped items. Three-leg bridle slings fabricated with legs of different lengths are useful for lifting loads with uneven pick points. Three-leg bridle slings can also be fabricated with adjustable leg lengths for loads with an unknown center of gravity. Regardless of design, Trinity Sling’s three-leg lifting slings are manufactured to the highest rigging standards in accordance with ASME B30.9 requirements.

Trinity Sling tags all three-part bridles with the vertical working load limit (WLL) as well as 60^o, 45^o, and 30^o horizontal angles. (See chart for the WLLs by rope diameter.) The working load limit for all lifting angles provides an industry standard 5-to-1 design factor. Trinity Sling’s custom-designed tags are durable even in the most abusive environments. Each tag carries the sling’s serial number and length in addition to the stated WLLs. Tags are also available with InfoChip RFID tags for online documentation from this (Trinity’s) website. InfoChip online documentation can be used to remind customers of an annual recertification of three-leg slings recommended by Trinity Sling.

Three-leg bridle slings fabricated by Trinity Sling are individually designed to meet customers’ specific requirements. Bridles can be made with numerous fittings, including hooks, thimble eyes, shackles and shortening devices. Three-part slings can be made from all domestic material or high-quality imported material when cost savings is important. Regardless of material, all lifting slings manufactured by Trinity Sling meet the load ratings stated on this webpage with a full 5-to-1 design factor.
