<p>The system has two individual strands (1, 1 asterisk) running parallel along longitudinal direction. The strands are arranged such that sum of the strands forms a trapezoidal-shaped carrying strap (11) with planar top and bottom sides (4, 5) in cross-section. The strands include a tensioning unit (2) with opposite impact directions (Z, S). The unit is coated by an elastomer coating (9) such as polyurethane or ethylene-propylene-diene rubber coating and made of synthetic fiber i.e. aramid fiber, and metal. A surface of the strands is made of non-migrating and friction-reducing material.</p> |
