Abstract:
Ein flexibles, umlenkbares Zugorgan (16) wird für statische und dynamische Lasten, insbesondere für Personenlifte, Warenlifte, Krane und Fahrzeuge eingesetzt. Das Zugorgan (16) umfasst wenigstens eine Litze (18) aus zugfesten Einzelelementen (10), wie Fasern, Drähten und/oder Bändern. Wenigstens ein Teil der Einzelelemente (10) der Litze (18) ist durch eine Beschichtung (12) und/oder Füllmaterial in Form von Fasern (28) und/oder schüttfähigem Pulver beziehungsweise Granalien (30) in Abstand gehalten. Nach bevorzugten Varianten ist wenigstens ein Einzelelement (10) einer Litze (18) durch einen elektrisch gut leitenden Draht (46) oder einen optischen Leiter (44) ersetzt.
Abstract:
A method and machine for manufacturing and laying a plurality of elongate elements into an umbilical (2) is shown. The umbilical (2) comprises a core element (5), a plurality of conduits (7) and/or cables (8) situated outside the core element (5), filler material around and between the conduits/cables and a protective sheath surrounding the conduits and filler material. The finished cable cord is characterized in that the filler material is in the form of inner, elongate channel elements (6) having outwardly opening channels, adapted for receipt of the conduits/cables, and outer, elongate channel elements (9) having inwardly opening channels adapted for receipt and final enclosure of the conduits/cables.
Abstract:
A wire rope (10, 20), comprising: a core (12, 22), a plurality of outer strands (18, 28) and a plurality of separator strands (17, 27) laid on said core (12, 22), and a first plastic jacket (19) around said plurality of outer strands (18, 19) and said plurality of separator strands (17, 27), wherein said plurality of separator strands (17, 27) extend from said core (12, 22) and in-between each pair of said plurality of outer strands (18, 28) so as to produce and maintain gaps between said pair of said plurality of outer strands (18, 28). Plastic impregnation of the wire rope (10, 20) can be ensured due to the separator strands/17, 27).
Abstract:
A cord obtained by twisting a plurality of strands each composed of a plurality of filaments is provided. A circumferential surface of the filament is coated with unvulcanized rubber to improve rubber intrusion, thereby improving corrosion resistance and suppressing twisting-loss.
Abstract:
A wire rope including at least one metal wire and at least one fluoropolymer fiber. Preferably, the fluoropolymer fiber is present in an amount less than about 25 weight %, and in alternative embodiments less than 20 weight %, 15 weight %, 10 weight %, and 5 weight %. The fluoropolymer fiber is preferably PTFE, and most preferably expanded polytetrafluoroethylene (ePTFE). The wire rope is useful in tensioned and bending applications.
Abstract:
In order to improve visibility and hence to reduce the risk of accidents, a rope, for example a wire rope, is equipped with a number of luminous elements. A luminous element may in this case assume the position of a wire or of a braid, may be integrated in an insert, or may be guided in the spaces between wires or braids and preferably within the theoretical rope circumference. The luminous element may also itself be composed of luminous elements which are twisted together, are twisted or are laid. For strain relief, the luminous elements may be equipped with a reinforcement in the form of a strand, or with a mesh. The luminous element is intended to be connected to a source. In the state when it is fed, the luminous element is actively luminous. Owing to the improved visibility, rope lights may be used not only for a safety function but also for an aesthetic appearance.
Abstract:
A reinforcement for a building works structure comprising an assembly of solid wires. The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath made of plastic material enclosing the bundle and providing it with cohesion.
Abstract:
A wire rope is provided having a central core strand about which are wound outer strands. Non-linear spacer wires are present in the gaps between outer strands to assure the uniformity of such gaps and provide passageways from the interior to the exterior of the wire rope. A coating, usually of a suitable thermoplastic, is extruded into such rope to extend continuously from the core and between adjacent outer strands and through the passageways.
