TWINTEX® ...the Lifting Solution

The TWINTEX® Roundsling, developed by SpanSet, Inc. ismanufactured from a continuous loop of high-tenacity polyester yarnencased in a smooth, doubled-wall tightly woven cover without anyedge seam. Because the load-bearing core yarns are encased by thecover, they are protected from cuts, abrasion, and the harmful effectsof ultra-violet rays. Removal from service can be determined if the redstriped white core yarns can be seen through any holes or cuts in thecover. Most TWINTEX® Roundlings feature a cover made from thesame type of yarns as the core, permitting a quick externalexamination to reveal any possible chemical damage that may havealso affected the load-bearing core yarn which might require theslings’ removal from service. Higher capacity SpanSet TWINTEX®Roundslings, E300 and above, feature a Cordura nylon cover toprovide greater abrasion resistance.

SPANSET TWINTEX® ROUNDSLINGS have a core of endless, high tenacity, polyester yarn encased in atough, double-wall polyester cover.

TWO-PLY CONSTRUCTION - Twintex® roundslingshave a two-ply cover which protects the load bearingcore yarns. (See Fig. 1) The covers are color-coded to make load capacity easily identifiable.

Special Features:

Color-coded for positive sling capacity identification

Consistently matched lengths

Double-wall, woven seamless cover for longer sling life

Soft and light weight for easy rigging, handling and storage

Durable capacity tag provides serial number traceability

No loss of strength from abrasion on cover

Red-striped white core warning yarns provide positiveindication for sling replacement

Easily conforms to the shape of the load

Low elongation (approx. 3% at rated capacity)

Sling can be extended by rotating bearing points

*Do not exceed rated capacities. Rating must be reduced when slings areused at angles of less than 90 from horizontal. See Sling Angle Chart.**The use of ANY roundsling with a nylon cover and polyester load-bearingcore yarn makes the detection of chemical damage to the core yarnextremely difficult. Use of such roundslings in chemically activeenvironments, ESPECIALLY THOSE WHICH INCLUDE STRONGALKALIS, is not recommended. Alkalis can damage the polyester core yarn without damaging the nylon cover, making inspection for this type ofdamage almost impossible. In such chemically active environments,roundslings using covers made from the same fiber as the core yarn isrecommended, because the environment will damage the cover either before or at the same time as the core yarn, making inspection anddetection much more reliable. If in doubt, return the roundsling to SpanSetfor inspection and proof testing

TWINTEX® Roundslings Sling Angle CapacitiesSling Angle ChartChemical Resistance ChartInspection CriteriaWarranty Information

!!WARNING!!The capacity of a sling to lift weight DECREASES as the angle of the sling moves away from

being vertical. If the angle of the sling is not taken into consideration before selecting a sling tolift a load, SERIOUS INJURY OR DEATH COULD RESULT from the load being dropped

Sling Angle Capacities

If you know the lifting angle of the sling being used, you can apply theCapacity Reduction Factor A or the Load Multiplier B in the Sling Anglechart. If you don't know the angle:

Attach the sling(s)Apply lift until the slings are taut and the load is ALMOST ready toleave the ground (BUT DO NOT LIFT THE LOAD OFF THE GROUND!!)Measure the length of the sling between the lift point and the loadMeasure the height between the lift point and the load (see Fig. 1below)

Capacity Reduction Factor

When you know the appropriate rated capacity of the sling, and youneed to calculate its actual capacity (based on the sling angle), follow theinstructions below: (The example uses a measured length of 12 feet and a measured height of 8 feet.)Measured Length (L): 12 feetMeasured Height (H): 8 feetReduction Factor (RF) = H/L=8/12 =0.667Rated Capacity* of sling = 1,000 lbs.Actual Capacity of sling = RatedCapacity x RF = 1,000 X 0.667 = 677 lbs.

Situation 2Load Multiplier

When you know the actual weight of the load, and you need to calculate theappropriate rated capacity (based on the sling angle) of the sling to lift theload, follow the instructions below: (The example uses a measured length of 12feet and a measured height of 8 feet.)Measured Length (L): 12 feetMeasured Height (H): 8 feetLoad Multiplier (LM) =L/H=12/8 = 1.5Load weight: 1000 lbs.Necessary Rated Capacity* of sling =Load Weight x LM = 1,000 X 1.5 = 1,500 lbs.

Inspection Criteria for Twintex® Roundslings

Remove from Service When:

Cuts to sling cover expose red-striped white core yarnsHoles, tears, snags or abrasions expose red-striped white core yarnsend fittings are pitted or corroded, cracked, distorted or brokenThe sling shows signs of melting, charring, or chemical damageCapacity tag is illegible or missingOther visible damage which causes doubt as to the strength of the sling
