Abstract:
The invention relates to a heavy-duty roundsling, which comprises an endless load-bearing core containing multiple turns of a strand material comprising high-performance fibres, and a protective cover made from interlaced strands comprising high-performance fibres, and wherein the mass ratio of high-performance fibres in the core to high-performance fibres in the cover is from 0.15 to 2.0. Said roundsling shows an advantageous combination of properties, like high strength, low weight, and high durability; enabling a higher number of lifting operations than known metal or synthetic slings, especially of heavy goods with e.g. sharp edges.
Abstract:
A product comprising a plurality of interlaced yarns wherein at least a first yarn having a tensile strength, having a value TS in N/tex, said first yarn containing a plurality of UHMWPE fibres having a titer, having a value T in den, wherein the ratio T/TS is at least 5 den.tex/N. The tensile strength is obtained by adjusting the drawing ratio or the UHMWPE filaments / fibres accordingly. The product shows resistance to abrasion. The product can be a rope or round slings, comprising a sheath / jacket comprising said first yarn.
Abstract:
A cable or rope (10-1; 10-2), of the composite type, comprising: a inner metallic rope or core (10-A), consisting of a plurality of metal strands (10-A'), and a plurality of covering layers formed around the inner metallic core (10-A), wherein the covering layers comprise a first layer (10-B) of Kevlar formed around the inner metallic core (10-A), and a second layer (10-C) of polyester that is formed around and covers the first layer (10-B) of Kevlar, and wherein the first and the second coating layer, respectively Kevlar and polyester, are made with a fabric of braided yarns, or, according to a further embodiment (10-2) of the composite cable, the covering layers comprise a further third layer (10-C), of Kevlar and/or Dyneema, which is formed around and covers the second layer (10-C) of polyester, in turn formed and arranged around the first layer (10-B) of Kevlar. The cable or rope of the invention substantially innovates over the known conventional cables. The invention also relates to an innovative anchoring and safety system (20), based on the use of a rope and directed to put in safety roofs (RO) and the roofing of buildings against accidental falls from an height of the people working on them, comprising one or more anchorages (21), fixed to the roof (TE) to make safe and sure, in each of which the rope (E) is stably locked by screwing, so as not to create problems of instability for the people that is attached to the rope.
Abstract:
Eine Rundschlinge zum Heben von Lasten, mit einem aus Fasern (2') gebildeten Innengelege (2) und einer das Innengelege (2) aufnehmenden, aus einem Gewebe gebildeten Umhüllung (3). Um eine solche Rundschlinge bei verbesserten Gebrauchseigenschaften webtechnisch herstellen zu können, wird die Umhüllung (3) durch einen dicht und in Querrichtung (Q) elastisch an dem Innengelege (2) anliegenden, aus radialer Richtung (R) elastisch auf das Innengelege (2) drückenden Gewebeschlauch mit in Richtung des Längsverlaufs (L) der Rundschlinge (1) ausgerichteten Kettfäden (4) und einem quer zum Längsverlauf (L) der Rundschlinge (1) ausgerichteten Schussfaden (5) gebilden.

Abstract:
The instant invention is a rope. This rope includes a blend of filaments including a first filament, and a second filament. The second filament is fluorocarbon polymer filament.
Abstract:
Hawser, especially for use with demanding and long-lasting strains at offshore installations, with a core of parallel of braided core strings, onto which a sheathing (19) of sheathing elements (18) is braided. The sheathing elements (18) have mainly parallel fibres (27), as they are joined together into ribbons (18) with transverse threads (28) by ribbon weaving.
