Twin-Path® Slings are made with K-Spec® high-performance fibers and a bulked nylon outer cover (Covermax®) that is very abrasion resistant. All Twin-Path® Slings have the Check-Fast® Inspection System and are repairable. The safety and inspection features found only in Twin-Path® products were created to overcome shortfalls riggers found in single-path roundslings. These slings are used worldwide in place of chain and wire rope slings for heavy lifts.
The Check-Fast® External Warning Indicator (EWI) on a roundsling product provides criteria for a pass/fail when the internal load-bearing core yarn may be damaged. Damage to the core yarn from fiber-on-fiber abrasion, fatigue, and severe overload can be detected. If the sling is overloaded beyond rated capacity, the EWI is designed to retract before the sling fails.
Rifled Cover® Technology is a major patented breakthrough for roundslings and is only available on Slingmax® high-performance roundslings. Rifled Cover® Technology works like the inside of a rifle barrel where, the bullet spins as it leaves the muzzle of the gun. The helical winding of the core fibers significantly improves strength, efficiency, and consistent and predictable breaking strength.
Fiber Optic Inspection is an optional addition to Twin-Path® slings. If heat or crushing damage has occurred, the fiber optic cable will not transmit light from one end to the other, giving the inspector cause to remove the sling from service and send it for repair evaluation.
The Twin-Path® Adjustable Bridle is a tool to find the center of gravity (COG). When the load is lifted, the bridle moves over the COG to balance and level the object. This tool was developed in conjunction with riggers in the field for lifting objects with uneven geometric proportions or off-center balance points.
When rigging in or around a hot environment (up to 300°F or 150°C), use a Sparkeater® sling to lift the load without marring the surface of the lifted piece. These slings are made with high temperature core yarns and a high temperature cover.
This is the only single-path, high-performance roundsling with the Check-Fast® Inspection System and Covermax® Cover. The Covermax® Cover is the most durable cover available for a synthetic sling. Also available in polyester – polyester cover and polyester core yarn.
