TWIN-PATH SLINGS ®
THE WORLD’S SAFEST, LIGHTWEIGHT LIFTING SLINGS
Manufactured by Beaver Brands | 1300 783 606
FOR LIFTS FROM 5 TO 600 TONNES
Twin-Path ® Slings have been an important rigging solution for heavy lifting applications across a number of industries for over 20 years. And now under licence with Slingmax ® , our Twin-Path ® Slings are manufactured to order in Australia, supplied within short lead times.
Not only do the slings have the precision, strength and flexibility to successfully perform lifts from 5 tonnes
to an incredible 600 tonnes – they are a fraction of the weight of wire rope slings.
The lightweight nature of the slings, coupled with several important safety features ensures lifts are performed quicker, safer and much easier than traditional wire slings.
Twin Path ® Slings have been used around the world since 1987.
K-Spec ® Core Fibre Technology
Unlike other fibre slings, Twin-Path ® Slings are constructed from a unique proprietary blend of K-Spec ® high-performance fibres, which will not stretch under load – enabling the accurate planning of a heavy lift. Less time and manpower is spent on rigging for most construction and maintenance schedules and a range of engineered protective pads and covers protect the slings from wear and tear.
Twin Path ® Slings contain K-Spec ® high performance, no stretch fibres.
CornerMax ® Sleeves provide cut protection for a variety of edges.
The unique slings are capable of safely lifting up to 600 tonnes.

ADVANTAGES
Handling Features
Cost Efficiencies
Wear Resistant Covermax ® Outer Cover: The fabric is four times more abrasion resistant than common nylon or polyester, increasing the sling life. Repairable: Twin-Path ® Slings can be repaired by the manufacturer if the internal core fibres are not already cut or damaged. All slings are re-tested after repairs are completed. Reduced Rigging Times: Rigging can be reduced by as much as 80% with less exposure to possible accidents. Low Maintenance: Twin-Path ® Slings do not require lubrication or annealing like wire rope.
Weight Advantage: 80% lighter than wire rope and chain slings and 50% lighter than polyester slings. Control of Slings: Rigging becomes quick and more manageable due to the low weight. Storage retrieval and salvage: Easily rolled up and shelved after use. Transportable and can easily be tossed in the back of a car or van. Marine Applications: The slings do not absorb moisture and are naturally buoyant, making them ideal for all off- shore and salvage work.
Safety Features
Twin-Path ® Sling Design: Constructed using two independent paths each capable of carrying the rated working load limit.
Low Stretch: Less than 1% elongation at working load limit.
Chemical Environments: Can be safely used in chemical environments.
Twin Path ® Slings are 80% lighter than wire rope slings.
Check-Fast ® Early Warning Indicator (EWI): The Check-Fast ® system provides for a pass/fail inspection of the internal load bearing core yarn. Optic Fibres: The optional optic fibre system can alert you to heat exposure, cutting and chemical damage of the core fibre, simply by shining a flashlight into one end of the optic fibre.
The slings are ideal for marine applications.
Twin Path ® Slings can be cost effectively repaired, if the core fibres are not already cut or damaged.

SAFETY FEATURES EXPLAINED
Two Independent Cores
Check-Fast ® Inspection
Twin-Path ® provides unique, patented backup protection. There are actually two independent cores of K-Spec ® fibre in the one sling. If a single path is damaged in use, the second path will perform as a backup and maintain control until the load is lowered. The Twin-Path ® helps reduce the potential for catastrophic material mishandling. Another early warning system is built into Twin-Path ® slings through the use of two independent, colour-coded covers. If the outer cover is cut, the patented red inner cover is instantly visible, providing a visual alert to remove the sling from service. As long as the inner core yarns are not damaged, Twin-Path ® slings can be repaired with bulked nylon patches, proof tested and re-certified.
The Check-Fast ® system provides for a pass/fail inspection of the internal load bearing core yarn. Damage to the core yarn from fibre on fibre abrasion, fatigue, and severe overload can be detected. If the sling is mistakenly loaded beyond rated capacity, the early warning indicator (EWI), which is the internal load bearing core yarn, will disappear before the sling fails.
If the early warning indicators (EWI) is missing, the sling may be unfit for use.
Rifled Cover ® Technology
Twin-Path ® Slings consist of two independent cores.
A major breakthrough for improved break strength is the spinning or helical winding of the core yarn within Twin-Path ® Slings. This process increases the slings breaking strength by 18% without the need for any additional core yarn.
Superior Patented Design Features
Optional Fibre Optic Cable
Armor Wear Pads resist abrasion to prevent sling damage.
Covermax ® outer cover, is 4 times more abrasion resistant than polyester outer cover.
Safety Red inner sleeve
acts as an early warning device when the outer sleeve is cut or worn.
The simple fibre optic test indicates whether a sling has sustained heat or chemical damage.
The optional fibre optic cable provides another simple and effective method of inspection. A light shone through one end of the fibre optic cable will travel throughout the body of the sling and reflect out the other end. A light that does not pass through the sling may indicate heat or chemical damage.
Armor Wear Pads are removable or sewn directly over sling.
Optional optic fibre allows for an internal integrity check of the core yarn.
K-Spec ® high performance fibres have less than 1% elongation at rated capacity.
Twin-Path ® design, contains 2 individual paths of core yarn.

TWIN-PATH ® SLING PROTECTION
CornerMax ® Pads and Sleeves
Most synthetic sling accidents are caused by cutting. There are many kinds of protective sleeves and pads available, but only two synthetic protectors provide adequate cut protection: CornerMax® Pads and CornerMax® Sleeves have been engineered and tested to provide 4464 kg of protection per centimetre of sling width.
CornerMax® pads are designed for 90° straight edges, whereas CornerMax® sleeves are for other edges.
CornerMax® Pads create a “tunnel” of cut protection – a no-touch zone. Therefore, the edge does not come in contact with the pad or sling. Note that the sides of the pads must be completely supported in order to create and maintain the “tunnel”.
Sling Protection
The chart below shows the results of testing slings protected by 12 different synthetic materials that are often used for sling protection. In our tests, ten of the most commonly used materials do not allow a sling to reach its working load before the sling is cut and fails. The CornerMax® pad and sleeve allow the synthetic sling to meet its working load with no damage to the sling or the protection. CornerMax® sleeves may look like traditional protection sleeves, but are made of a high tech fibre that is specially woven to provide cut protection for a variety of edges and surfaces.
CornerMax® sleeves are made of a high tech fibre that is specially woven to provide cut protection for a variety of edges and surfaces.
Other Forms of Sling Protection
For synthetic slings, the most critical decision is whether cut protection is needed. In some circumstances no cut protection, or simplified softeners only, are required. At Beaver Brands we have a full line of engineered softeners that are excellent for abrasion protection or for protecting a load surface.

G-Link Connectors
G-Link Connectors are used to lengthen or shorten a Twin-Path ® Sling to it’s desired length. This enables the sling to be used for a number of different applications.
Two G-Link Connectors are used to lengthen or shorten a sling.
Twin-Path ® Adjustable Bridles
Twin-Path ® Adjustable Bridles are a very useful rigging tool. They replace standard two or four leg bridles, with the additional value of self-adjustment to awkward loads. One leg has twice the capacity of the other leg. As tension is applied, Twin-Path ® Adjustable Bridles self-adjust over the centre of gravity to find the lifting point for level, load handling.
