Abstract: A wire rope is provided which has an independent wire rope core (IWRC) covered by a plastic jacket. Outer strands are laid on this plastic jacket and wormings or spacers extend from the plastic jacket in between the outer strands to form gaps between the outer strands. Another jacket is provided over the outer strands which also fills the gaps between the outer strands. Both the IWRC and the outer strands are preferably lubricated. A method is also disclosed for manufacturing such wire rope.

Abstract: A wire rope which has an independent wire rope core (IWRC) and outer strands laid around the core. This wire rope has an improved fatigue life when the outer wires of the core and of the outer strands are galvanized. The wire rope may be either fully or partially impregnated with plastic, if desired.

Abstract: A plastic impregnated wire rope is provided with plastic bands between its core and its outer strands so as to prevent contact between the wires of the core and those of the outer strands during flexing of the rope. This produces a substantial increase in the life of the rope. The method for manufacturing such rope involves wrapping plastic bands on the core just prior to laying outer strands on the core and on top of the plastic bands. Thereafter, the so formed rope is impregnated with molten plastic, which is then allowed to solidify.

Abstract: A low stretch elevator rope (10) is obtained in which a plastic core (12) has a central strength member (18) that does not increase the weight of the rope by more than 5%. Moreover, the plastic core (12) has a diameter exceeding 50% of the diameter of the rope (10), when measured prior to winding steel strands (14) onto the core (12). The steel strands (14) that are wound around the core (12) are conventional and are so wound that the plastic material of the core (12) essentially fills the inner interstices (16) between the steel strands (14).

Abstract: A wire rope is disclosed, which has at most 18 outer strands and an independent wire rope core, with the strands of the core being laid in the opposite direction to the outer strands of the rope, and a nylon jacket is provided between the core and the outer strands of the wire rope.
