Methods for non-destructive testing of synthetic ropes is described, where the rope in use is subjected to X-ray, terahertz, permanent magnetic field or electromagnetic analysis to determine a pattern, the results of the analysis are compared with a standard pattern determined by the analysis, and the results of the comparison are used in determining whether the rope is fit for use; where the rope comprises at least two types of fibers, the first fiber type has a density which differs from the density of the second fiber type and the second fiber type is of the same polymer material as the first fiber type, but provided with a high-density or low-density material. Ropes suitable for use in this method are also described.

Method for non-destructive testing of synthetic ropes and rope suitable for use therein

A combined cable comprising a core cable of high-strength synthetic fibers, which take the form of a twisted bundle of monofilaments or a plurality of twisted bundles of monofilaments, and comprising an outer layer of steel wire strands, is characterized in that the bundle or bundles of monofilaments is or are stretched, with a reduction in diameter, and held in this state by a sheathing, in particular a braided sheathing. The extension under strain of the core cable under load is thereby reduced, so that the load distribution between the cross section of steel and the cross section of synthetic material of the cable improves.
