Synthetic fibre rope without jacket

Abstract

With this synthetic rope, which has multiple layers of load-bearing aramide fiber strands (9, 10, 11) laid together, it is proposed that instead of an extruded protective synthetic sheath as hitherto, only an additional coating (19) of the synthetic fiber strands (4, 5) in the outermost layer of strands (6) with impregnating substance and additives of UV stabilizers, short fibers, oxidation and reduction blockers is applied, and thereby a reliable protection against environmental influences damaging to the rope, as well as an unchanged adequate resistance of the synthetic fiber rope (1) to abrasion, is ensured.

Description

field of invention

[0001] The invention relates to a synthetic fiber rope, preferably an aramid synthetic fiber rope, comprising a coating according to the preamble of claim 1 . Background of the invention

[0002] In handling technology, for example in lifts, in construction for cranes, and in surface mining, ropes, especially moving ropes, are important elements of machines and are subjected to load-bearing use. A particularly complex aspect is the load of driven ropes, such as some ropes used in crane construction and for suspending cable cars. In these cases, very long ropes are required, requiring the smallest possible mass or weight from energy considerations. High tensile strength synthetic fiber ropes, such as aramids or aramides for short, which have highly oriented molecular chains, meet these requirements better than ordinary steel cords. However, materials such as aramids are very sensitive to ultraviolet (UV) light, and the environment has oxidizing or reducin...
