Abstract:
The invention relates to a combined cable having a core cable made of high-strength plastic fibers present as a twisted monofilament bundle (1) or a plurality of twisted monofilament bundles (6), and having an external layer (2, 7) of steel wire strands (4, 5), characterized in that the monofilament bundle or bundles (1, 6) is or are stretched to reduce the diameter and held in a cladding (2, 7), particularly braided cladding, in this state. The strain of the core cable under load is thus reduced, so that the load distribution between the steel cross-section and the plastic cross-section of the cable is improved. In the same sense, in reverse, in order to have the strain behavior of the strand layer approach that of the core cable, the cable has an intermediate layer (3) made of an elastic plastic, in which the steel wire strands are pressed at a distance from each other, such that the external layer stretches under load and contracts radially.
Abstract:
Ein kombiniertes Seil mit einem Kernseil aus hochfesten Kunststofffasern, die als ein verdrilltes Monofilbündel oder eine Mehrzahl von verdrillten Monofilbündeln vorliegen, und mit einer Außenlage aus Stahldrahtlitzen ist dadurch gekennzeichnet, dass das bzw. die Monofilbündel unter Durchmesserverringerung gedehnt und in diesem Zustand durch eine, insbesondere geflochtene, Ummantelung gehalten ist bzw. sind. Die Dehnung des Kernseiles unter Last wird dadurch verringert, so dass sich die Lastverteilung zwischen dem Stahlquerschnitt und dem Kunststoffquerschnitt des Seiles verbessert. Um im gleichen Sinne umgekehrt das Dehnverhalten der Litzenlage demjenigen des Kernseiles anzunähern, weist das Seil eine Zwischenlage aus einem elastischen Kunststoff auf, in den die Stahldrahtlitzen mit einem Abstand voneinander eingedrückt sind, derart, dass sich die Außenlage unter Last dehnt und radial zusammenzieht.
Abstract:
A tubular outer member (1) of plastics material is extruded onto a solid cylindrical central member (3) of plastics material. The outer member (1) has symmetrically spaced grooves (2) for receiving respective wire strands (4).
Abstract:
A coated wire rope suitable for a running wire rope for cranes, elevators, etc. Wear of the rope caused by contact between a core rope and outer strands and contact between adjacent ones of the outer strands is prevented from occurring, wear of the rope caused by direct contact between a sheave and the outer strands is prevented from occurring, and excellent drive force transmission capability between the rope and the sheave and silence are realized. To achieve the above, uniformly spaced gaps defined by adjacent ones of outer strands (2) and the outer periphery of a core rope are formed by spacers, and the gaps are filled with a resin layer (301) integrated with an outer layer resin (300) positioned outside a circle circumscribing the outer strands.

Abstract:
A method of manufacturing an escalator handrail of the invention is characterized by including: a metallic steel-wire producing step of placing a center elemental wire and a plurality of strands so that the plurality of strands surrounds the center elemental wire, and applying tension to them so that each distance between the center elemental wire and each of the strands becomes the same, to thereby produce the metallic steel wire; a preheating step of heating the metallic steel wire to a temperature equal to or more than that of a thermoplastic resin in a molten state; a composite-material forming step of integrating the metallic steel wire heated with the thermoplastic resin in a molten state, and extruding them through a die finished into a cross-section shape of the escalator handrail to thereby form the composite material; and a cooling step of forcibly cooling the composite material.
Abstract:
A rope (210, 310) having a three-layered structure comprising a core layer, an inner layer and an outer layer, the core layer comprising one strand (225, 315), the inner layer comprising multiple strands (220) with an amount n and the outer layer comprising multiple strands (215) with an amount m, wherein n is an uneven number, and m is a number which has no common divisor with n, each strand is formed by multiple twisted metal filaments. By this structure fretting of the strands is reduced and the life time of the rope is improved. Also, the use of the rope in lifting application and an elevator system comprising such a rope are disclosed.
