Ultimatex Round Sling

Description of Ultimatex Round Sling

Ultimatex Roung Sling made from Technora specially developed aramid fiber for rope application. Lightest per capacity, and most suitable to rig ultra heavy lifting object.
It has excellent physical properties, such as high strength, low stretch, lower creep under sustaining tension than HMPE and high temperature resistance allows use under working temperature up to 350℉. Because of good bending fatigue resistance, it is also recommended to use over sheaves or flexing applications. The strength is higher than steelwire rope sling if same diameter and weighs merely 1/8 of steelwire rope sling. Light weight and flexibility enable easy use in narrow space situations.
Made up for good alternative to Steel Wire Rope Sling, convenient to handle as well. Get productivity increases.
Light weight reduces risks of back and other industrial injuries to riggers.

General structure of Ultimatex Round Sling

Features of Aramid Fiber

Maintain High-strength and High flexibility under humidity.
High thermal resistance, working temperature up to 350 ℉
Elongation at break point : 4.5%
Load Elongation : 1% below
Good resistance to organic solvent, acid and alkali.
Stability in brine and water vapor.
Excellent electrical insulation properties.

1)High strenght

It has 8 times stronger than steel and 3 times stronger than nylon or polyester.
It helps the product's weight lessen dramatically

2)Size stability with high strength

low elongation ratio and low stress relaxation modulus especially with low thermal expansion and shrinking.
No change in size below 200℃, 2% change at 400℃

3)Thermal resistance

Can be used for mamy long hours even at 200°C

4)High chemical resistance

It has good resistance to organic solvent,acid and alkali.
Stability in brine and water vapor. High resistance to hydrolysis.
