“High performance” round slings are defined as such because they are made with a special high modulus polyethylene fiber, which combines high tenacity and very low elongation.
Properties of HMPE / UHMWPE fiber
High performance polyethylene fibre is identified by the acronyms HMPE
(High Modulus Polyetylene) or equally UHMWPE (Ultra High Molecular Weight Polyethylene).
■ Tenacity 15 times higher than steel.
■ Weight 10 times less than steel.
■ Floats on water (specific weight = 0.97 g/cm3). Does not absorb humidity.
■ It does not suffer from fatigue stress (bending and torsion).
■ Excellent resistance to chemical agents and UV rays.
■ Melting temperature 140°C.
Characteristics of HMPE round slings
HMPE round slings consist of two parts: the load-bearing core and the core cover. The core is always made of HMPE. Different cover materials can be chosen, depending on the use of the sling.
■ Robust and flexible textile structure: adapts perfectly to the shape of the load.
■ Working load (WLL) up to 600 t.
■ Safety factor 7:1.
■ Breaking load (MBL) 4200 t.
■ Minimum elongation (0.5% of WLL; 3% of breaking load).
■ Lengths: 0.5 – 35 m.
■ High resistance to abrasion.
■ Working and storage temperatures: -40° +70°C.
