Guess which sling requires less effort to rig, has less chance of causing injury, is easier to transport and store, and costs less to use?

What Twin-Path® Users should know

with K-SPEC® load bearing yarns and Fiber Optic Inspection System.


WIRE ROPE – 400 lbs.

POLYESTER ROUND – 200 lbs.

TWIN-PATH® EXTRA – 44 lbs.

No matter what job you have to do, large or small; there is always a solution with Twin-Path® Slings. Note how easy it is to rigg and handle the slings.

The Ultimate Choice: TWIN-PATH®

Twin-Path® Slings are a sure solution to the need for slings that can lift materials and equipment surely. Through industry research and creative innovation this product line was developed with the specifications requested by you. Our sling technology and research led us to the discovery that available sling materials like nylon, polyester, wire- and fiber rope, and steel chains weren’t effective enough. Concern was expressed over:

  • potential personal injuries
  • catastrophic material mishandling
  • awkward handling procedures
  • ergonomic workplace policies

Slingmax® developed a line of sling products which resolved these problems and that can be manufactured with any capacity and within extremely tight length tolerances.

Unirope® is a licenced Twin-Path® fabricator. All slings are manufactured, serviced, repaired, and proof tested in our Mississauga, Ontario and Montreal, Quebec facility.

During the Canadian Frigatte Building Program Unirope manufactured Twin-Path® slings to lift the 970 ton heavy modular ship sections into the dry dock at St. John Shipbuilding.

TWIN-PATH® Sling Line

Twin-Path®
TPC, TICE

Twin-Path® slings with Polyester yarns are essentially 2 complete slings in one, each making a separate connection between hook and load. If one of the paths is cut or damaged, the other path is still strong enough to hold the load for it to be lowered safely. Twin-Path® slings have a unique inspection system found in no other sling product.

Built-in Early Warning Check-Fast™ (EWI) System
Contrasting colour Inner- and Outer cover
Easy to handle, protects your hand and loads

Simple to store

Twin-Path® Extra
TPXC, TPXCE

Twin-Path® Extra slings are made with K-Spec Load Bearing Yarns which is stronger than steel but only about 1/5 of the weight of wire rope slings. TPXC slings were 50,000 times cycle tested to double the Working Load at TMT Laboratories without failure. Yarn-to-yarn abrasion tests showed that K-Spec withstood 5.5 times more cycles than polyester yarns.

Strongest and lightest lifting sling in the world
Built-in Early Warning Check-Fast™ (EWI) System
Double paths means double safety
Cover made from extra thick bulked CoverMax® fabric

Twin-Path®
Sparkeater

Sparkeater slings are made from 100% Aramid load yarns protected by a DOUBLE cover made from Nomex® flame resistant fabric. If you have a hot environment up to 150˚C (300˚F) use a Twin-Path® Sparkeater to lift the load without marring the surface. Ideal for welding shops and as black coloured suspension sling for stage riggers.

100% Aramid load yarns
100% Nomex® DOUBLE covers
Available in YELLOW for welding shops.

TWIN-PATH®: The Advantage

Twin-Path® Slings are actually two complete slings in one. This unique back-up protection provides 2 independent paths to connect the load to the crane hook or fitting. If one path is damaged in use, the second path will perform as a back-up until the load is lowered. Each path alone is as strong as at least 2-1/2 times of the total sling capacity. Twin-Path® helps reduce the potential of catastrophic material mishandling. We don’t recommend the abuse in the above picture but if damage occurred to your Twin-Path® Sling, chances are good that you could still maintain control of the load.

Double layered, colour contrasted independent covers provide extra protection and early warning. If the the inner red cover is visible the sling has been damaged. If the red cover or inner load bearing yarns are visible, remove the sling from service and send it to Unirope® for inspection and possible repair.

Overload Indicators (Check✓Fast™) and Fiber Optic Cables make it easy for inspection.
The patented early warning Indicator (EWI) system installed in one path, yellow-red, provides easy pass/fail inspection. Damage to the core yarn from abrasion, fatigue, and severe overload can be detected. If the sling is mistakenly overloaded the EWI is designed to disappear before the sling fails. The EWI can be combined with the optional Fiber Optic Cable.

TWIN-PATH®: Easy to Inspect

There are two kinds of tell-tail indicators: our Check✓Fast™ overload indicator – installed in one path – and a optional installed fiber optic indicator to warn of core yarn damage. (Sparkeater® slings are fitted with traditional shrink tails only.) Twin-Path® slings are
actually two slings in one. There is unique backup protection.
The separate inner cover shows red for warning that the sling is damaged and should be taken out of service.

Twin-Path® slings are repaired with patches like this. Each sling is proof tested after a repair.
