Abstract:
A wire rope comprising a plurality of strands (4-12) twisted together with each strand (4-12) being individually covered by a respective sheath (16) of rubber or rubber substitute. Each strand (4-12) comprises a plurality of wires (14) twisted together with the direction of twist of at least the outer wires (14) in each strand (4-12) being opposite to the direction of twist of at least the outer wires (14) in the strands (4-12) adjacent to it, the rope having an outer covering sheath (18) of rubber or rubber substitute. In this way, the wires (14) of adjacent strands (4-12) do not cross each other, and stress on them is reduced.
Abstract:
The invention relates to a method for producing a wire cable (1), wherein a core strand (3) is compacted and then braid strands (2) are stranded on the core strand (3), characterized in that the core strand (3) is hammered before stranding of the braid strands (2) in order to smooth the surface (10) thereof. A plastic layer is advantageously applied to the core strand (3) before stranding of the braid strands (2), wherein the braid strands (2) are pressed into the plastic layer (7), preferably while the plastic layer (7) is heated. In the preferred embodiment of the invention, the core strand is a core cable (3) and the braid strands are strands (2) of the wire cable (1) or the core strand is a heart strand (3) and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable (1) is obtained by hammering the core strand (3) in order to smooth it than by compacting a core strand (1) with a roller compressor. The invention further relates to the wire cable (1) and to a device for producing the wire cable (1).

Each of the stands including core strands (12) and outer strands (14) comprises core steel filaments (20) with the number of m and outer steel filaments (22) with the number of n. the diameter of the core steel filament (20) in the core strand (12) is Dec, the diameter of the outer steel filament (22) in the core strand (12) is Doc, the diameter of the core steel filament (20) in the outer strand (14) is Deo, the diameter of the outer steel filament (22) in the outer strand (14) is Doo, the ratio of Dec/Doc is not less than 1.04, the ratio of Dco/Doo is not less than 103, the ratio of Doc/Deo is not less than 1. The core steel filaments (20) and outer steel filaments (22) are polygonally preformed before being twisted into strands. The steel cord (10) is used for reinforcing off-the-road tire.
Abstract:
A synthetic rope for an elevator having improved resistance to compression and abrasion is provided and comprises a plurality of strands forming layers of the rope, each strand formed from a plurality of pre-twisted strands made from high modulus synthetic filaments. One or more of the strands or layers of strands may be impregnated with a lubricant, such as polytetrafluoroethylene, to reduce the abrasion among the strands and substrands, and increase the service life of the rope. The exterior of the rope may be covered by a jacket that provides for traction with the drive sheave. An elevator system comprising the claimed rope is also provided.

Abstract:
A stainless steel cable particularly for surgical procedures comprises a plurality of individual wire filaments (20). Groups of wire filaments (20) are twisted together in a first helical direction around a central wire filament to make a strand (10). A plurality of strands (10) are twisted together in a second helical direction around a core strand to make a strong, flexible cable. The first helical direction has the opposite sense to that of the second helical direction. In one embodiment, the cable has one hundred and thirty three wire filaments (20), each of diameter 0.0025 inch (64 (my)m), arranged in nineteen equivalent strands.

Abstract:
A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high- density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.
