Abstract:
The invention relates to a hybrid rope comprising a core element, a first and a second metallic closed layer surrounding said core element. The core element includes a bundle or construction of synthetic yarns. The first metallic closed layer includes a plurality of first wirelike members helically twisted together with the core element in a first direction. The second metallic closed layer includes a plurality of second wirelike members helically twisted together with said core element and said first metallic closed layer in a second direction. The cross-sectional area of the core element is larger than the total cross-sectional area of the first and second metallic closed layers.
Abstract:
Disclosed is a method for producing a high strength synthetic strength member containing rope capable of being used with powered blocks where such rope has lighter weight and similar or greater strength than steel wire strength member containing ropes used with powered blocks. Disclosed also is the product resulting from such method. The product includes a synthetic strength member, a first synthetic portion and a second synthetic portion. The first synthetic portion is enclosed within the strength member and the second synthetic portion is situated external the strength member. At least a portion of the second synthetic portion also is situated internal a sheath formed about the strength member. The first and second synthetic portions having differing elasticity values, the second synthetic portion having greater elasticity than the first synthetic portion. Preferably, the elasticity of the second synthetic portion is in a range of from 20% to 550% when measured at any temperature within 2°C of 0°C.
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 for elevator systems used to hoist, compensate, and govern an elevator car. The wire rope may include six to ten outer steel strands surrounding a central braided polyester core. The wire rope may include six to ten outer steel strands and six to ten inner steel strands surrounding a central braided polyester core. The braided polyester core may include 8-24 single- or double-braided outer strands surrounding a polyester core center that may include parallel fibers, twisted fibers, twisted strands, single-braided strands, or double-braided strands.
Abstract:
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.
Abstract:
A method for producing a strand or cable, in which fibers and/or wires are twisted at a twisting point to form the strand or cable. The fibers and/or wires are coated with a liquefied matrix material before and/or at the twisting point and are embedded in the matrix material during twisting. The fibers and/or wires are immersed in the matrix material before and/or at the twisting point and the formed strand or the formed cable is cooled after the twisting in order for the matrix material to solidify, preferably by air or in a cooling liquid, for example water.
