Disclosed herein is a device for protecting a climbing rope comprising a flexible sheath comprising a first edge, a second edge generally opposing the first edge, a first end, and a second end generally opposing the first end, a sheath connector assembly attached at the second end of the flexible sheath, and a primary rope connector assembly attached to the sheath connector assembly. Methods of making and using the device also are described.

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 fibers 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/fibers accordingly. The product shows resistance to abrasion. The product can be a rope or round slings, comprising a sheath/jacket comprising said first yarn.

Rope (4) having an eye (2). The rope (4) comprises a first rope portion (8) and a second rope portion (10). The first rope portion (8) and the second rope portion (10) are spliced into each other for forming a spliced connection for obtaining the eye (2). The first rope portion (8) and the second rope portion (10) are formed from an end portion of the rope (4).

A security device includes a flexible rope of diameter in the range 10-25 mm comprising helically wound strands with collars clamping the rope at spaced locations therealong. The spacing between the collars is less than or substantially equal to the rope diameter, and each collar has a wall thickness in the range 5-15% of the rope diameter. The axial length of each collar is normally no greater than the rope diameter. The collars engage the rope with sufficient pressure to prevent substantial relative lateral movement of the strands at each location.

A deicing device for a sheath of a structural cable, the structural cable comprising tendons housed in the sheath, the deicing device includes a base; a bearing element; and a power system configured to press the bearing element against the tendons while the base is in contact with an inner surface of the sheath, and to generate vibrations between the bearing element and the base.

An elongate body adapted to bend in a single plane, comprises a rope extending within a succession of individual tubular elements closely spaced along the rope. Each element has on two opposite sides of the plane an extended section engaging a recess in its neighbouring element, the profiles of the section and recess allowing relative rotation of adjacent elements in said plane. The tubular elements thus form an exoskeleton around the rope which must be breached before the rope can be cut. The geometry of the tubular elements can be such that notwithstanding gaps, the rope cannot be readily accessed unless the exoskeleton is broken.
