Slingmax Twin-Path Slings



Slingmax Twin-Path slings have Check-Fast® Inspection overload indicators, Covermax® Covers for superior abrasion resistance, and inner red covers as an aid to inspection.  Twin-Path® synthetic roundslings are used worldwide in place of steel rigging for heavy lifts.  They are approximately 10% of the weight of a steel sling and are repairable.  The Twin-Path® sling design, which has two individual paths of fiber working as one sling, gives the rigger confidence.  These slings have less than 1% elongation at rated capacity.  If productivity, safety, and precision are important, then Twin-Path® high-performance roundslings are your best choice.  Independent testing shows that K-Spec® core yarn is the longest lasting load-bearing core yarn in any sling.

Slingmax Twin-Path Extra Check-Fast Slings

These slings have overload indicators, Covermax® covers for superior abrasion resistance and inner red covers. They are used worldwide in place of steel rigging for heavy lifts. They  are  approximately  10%  of  the  weight  of  a  steel sling and products are repairable. The Twin-Path® patented design provides the rigger with two independent connections between  the  hook  and  the  load  for  protection  assurance. These slings have less than 1% elongation at rated capacity.If ergonomics, productivity and safety are important, then these  slings  are  your  best  choice.  Independent  testing shows that K-Spec® is the longest lasting load bearing core yarn in any sling.

Slingmax Check-Fast Inspection System

The Check-Fast® System is designed to improve job-site safety. The ✓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 ultraviolet (UV) light degradation, 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 sling inspector now has a GO/NO-GO inspection device rather than relying on a subjective hand-over-hand inspection to make an educated guess if the load bearing core yarns are in good condition. This safety  system  is  available  for  High  Performance  K-Spec® Fiber Roundslings or polyester roundslings fabricated by authorized SLINGMAX® Dealers.

Fiber Optic Inspection for Twin-Path Slings

Twin-Path® slings have the Fiber Optic inspection system. The condition of the internal core yarn can be inspected just by checking the continuity of  the  fiber  optic  cable.  If  crushing  or  cutting, heat or chemical damage, has occurred then the damage  to  the  fiber  optic  cable  will  destroy  its ability to transmit light from one end to the other giving the inspector a reason to remove the sling from service and send it in for repair evaluation. The fiber optic cable will conduct light using natural, overhead or flashlight sources. The inspector simply covers and removes his finger from one end and watches the other end for blinking which indicates that the sling is OK to use for another lift.

Rifled Cover® Technology is a major patented breakthrough only available on Slingmax® Twin-Path® high-performance fiber 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 and efficiency.

Twin-Path® high-performance roundslings with patented Rifled Cover® Technology yield three major advantages:

  1. Increased strength-to-weight ratio. 17% increased breaking strength with the same amount of core yarn.
  2. Consistent and predictable breaking strength for every sling.
  3. Repeatability in the manufacturing process.

Twin-Path® roundslings are made with the Slingmax® Covermax® Cover. The Covermax® Cover is made with a heavy-duty, double-layer industrial nylon material. The outside cover is green and the inside cover is red. If damage on the green cover allows red to show through, return the sling for factory inspection and repair. This cover has been tested to provide the best ultraviolet (UV) protection and the best abrasion protection on any commercially-available synthetic lifting sling.
