ABSTRACT:
The safety mountaineering rope (1) has a core comprising a plurality of core ropes (2).
In order to improve the tearing resistance of the rope (1), the rope core surrounds in the manner of a tube at least one cavity (3) extending over the entire length of the rope (1). In this case the cavity (3 )is filled by means of at least one resilient filling material or body, resilient at least as viewed in the radial direction of the rope (1), and which, when the rope (1) is pulled over an edge and with a high tensile force for example, results in a considerable momentary flattening of the cross-section of the rope when pulled over the edge and thus a considerably wider support of the rope (1) on such an edge. In addition, the rope core (2) is surrounded by a rope sheathing (4) provided with a protective layer (5) impervious to particles of dirt.
