Embodiment Construction

[0029] figure 1 A longitudinal element 13 is shown, by means of which traction and / or load-bearing forces can be absorbed, in particular even at very high forces. The longitudinal element can be used in various fields, as explained below according to different embodiments.

[0030] According to the invention, this longitudinal element 13 configured as a wire is made of a core 12, which is preferably steel or Stainless steel.

[0031] A metal sheath 15 is arranged around the core 12 formed by the fibers 11 and remains connected along the longitudinal extension of the longitudinal element 13, for example by welded seams 15' at the abutment faces of the side edges.

[0032] Such welding with the metal sheath 15 produces an air- and water-tight layer for the fibers 11 . Thus, these fibers remain permanently sealed against UV light and the atmosphere, which results in a longer service life with virtually unchanged strength, but virtually no aging. If the metal casing is made of...

Abstract

The invention relates to a longitudinal element (13) produced with a core (12) made of high-strength fibres (11) and at least one metal casing (15), preferably steel, surrounding the core (12). In this way, there is the significant advantage that these high-strength fibres, which are very lightweight in relation to their strength, are protected in a number of ways, namely against humidity, moisture, UV light and other environmental influences. In addition, the metal casing provides the fibres with protection against transverse loads. In this way, all the high-strength properties of the traction or suspension means are maintained over a sustained period.

Description

technical field [0001] The invention relates to a longitudinal element according to the preamble of claim 1 , in particular a longitudinal element for a traction device and / or a carrying device. Background technique [0002] In the combined rope-shaped traction device or carrying device according to EP-A-2 165 017, a longitudinal element is disclosed as a core rope made of high-strength plastic fibers made of twisted single A tow or a plurality of twisted monofilament tows are produced and produced with an outer layer of steel wire strands. The monofilament bundle is stretched during diameter reduction and is held in this state by the in particular braided envelope. Thus, the stretching of the core rope when loaded is reduced, resulting in an improved load distribution between the steel cross-section and the plastic cross-section of the rope. [0003] In order to bring back the stretching properties of the strand layer to that of the core cord in the same sense, the cord h...
