Twin-Path® Extra Sling with Covermax® and K-Spec®
Core Yarn with Check-Fast® Inspection TPXCF
US Patent #5,651, 572 (Sling)
US Patent #7,926,859 (Covermax)
TPXCF slings
This is the world’s first truly ergonomic sling Covermax® covers for superior abrasion resistance. These are made in sizes up to 600 tons vertical rated capacity. Larger capacity slings are available. These slings have overload indicators, inner red cover, and are used world-wide in place of wire rope for heavy lifts. They are approximately 10% of the weight of
a steel sling. These products are repairable. The Twin-Path® patented design provides the rigger with two connections between the hook and the load for redundant back-up protection. These slings have less then 1% stretch at rated capacity. If ergonomics, productivity and safety are important, then these slings are the only choice. This is the lightest and strongest sling on the market today with K-Spec® —the longest lasting load bearing core yarn, backed by independent testing.

CheckFast Inspection System image
US Patent #7,661,737 (Check-Fast)
Check-Fast™ Inspection System–now available in Twin-Path® Extra Slings
The Check-Fast® System is designed to improve job-site safety. The Check-Fast® Tag and External Warning Indicator (EWI) on a roundsling product provides for a pass/fail inspection of the internal load bearing core yarn. Damage to the core yarn from fiber on fiber abrasion, fatigue, and severe overload can be detected. If the sling is mistakenly overloaded beyond rated capacity, the EWI is designed to disappear before the sling fails. The inspector no longer has to feel and squeeze around the entire sling to guess if the core has been severely overloaded. This safety system is available for polyester or High Performance K-Spec® Fiber Roundslings.



The Check-Fast™ System is an independent sacrificial element in the roundsling and is not a part of the actual load bearing structure of the sling. If the Check-Fast™ System indicates internal damage it does so without further weakening of the bearing core.
Larger Capacities Available Upon Request
*Dimensions can vary according to the hardware or bearing points the slings are used with. Minimum is "tapered" width; Maximum is the flat tubing width.
WARNING
Can fail if damaged, misused or overloaded. Inspect before use. Use only if trained. Observe rated capacity. Avoid sharp
edges and exposure to acid, alkali, sunlight and temperatures over 180° F. Death or injury can occur from improper use or maintenance.
