摘要:
A rope structure comprising a plurality of formed composite strands. Each of the formed composite strands comprises fiber material and matrix material. The fiber material within the matrix material is twisted. The shapes of the plurality of formed composite strands are predetermined to facilitate combination of the plurality of composite strands into the rope structure.
摘要:
A method of fabricating a composite rope structure comprising the following steps. Impregnated yarns comprising fibers within a resin matrix are fabricated at a first location. The impregnated yarns are transported from the first location to a second location. The impregnated yarns are dispensed at the second location. The resin matrix of the dispensed impregnated yarns is cured at the second location to obtain the composite rope structure.

The present invention refers to a metal rope with improved features, in particular having high ultimate tensile strength and a high number of sustainable fatigue cycles. The metal rope (10) according to the present invention consists of a plurality of strands (12) wound around a central core (14) and is characterised in that the central core (14) is made of a fibre spun from a liquid-crystal polymer. Preferably, this fibre spun from a liquid-crystal polymer is Vectran ™ .

Bei diesem Kunstfaserseil (1) sind die Litzen einer Litzenlage gegenseitig beabstandet. Mit der gegenseitigen Beabstandung (d1) können sich die Litzen (7) der äusseren Litzenlage (2) radial in Richtung des Seilzentrums bewegen und einen radialen Druck auf die Litzen (8,9) der ersten inneren Litzenlage (3) ausüben. Der radiale Druck wird von den Litzen (8,9) der ersten inneren Litzenlage (3) auf die Litzen (10) der zweiten inneren Litzenlage (4) weitergeleitet. Der radiale Druck wird von den Litzen (10) der zweiten inneren Litzenlage (4) auf die Kernlitze (5) weitergeleitet. Der radiale Druck nimmt von Litzenlage zu Litzenlage nach innen zu. Der weiche Seilmantel (6) wirkt in Umfangsrichtung Ur nicht als Stütze zwischen den Litzen (7).
摘要:
A large diameter rope (10) having improved fatigue life on a sheave, pulley, or drum is disclosed. This rope includes a blend of HMPE filaments (16) and liquid crystal polymer filaments (18) selected from the group of lyotropic polymer filaments and thermotropic polymer filaments. The rope may be constructed as a braided rope, a wire-lay rope, or a parallel core rope.

The invention relates to rope-like structures, in particular, kernmantel ropes, cords and cables in which the individual fibres, threads or thread bundles (5, 5', 6, 6') are connected to each other such that the above are non-slip relative to each other. Such rope-like bodies have an improved resistance to extension and an improved knot stability. Kernmantel ropes (10) have a proportion of the core fibres (5') in the sheath region (2) and connected therein to the sheath fibres (6), whilst a proportion of the sheath fibres (6') lie in the core region (1) and are connected therein to the core fibres (5), such that the at least one sheath (4) is fixed to the at least one core (1), such that the above are non-slip relative to each other. Cords and cables with similar properties are disclosed. Such ropes are applicable in the field of work security, in water, sailing and mountain sports and for the fire service, army, police and rescue units as well as in Jacquard machines.

A travelling cable of an elevator, more particularly of a passenger transport elevator and/or freight transport elevator, includes a protective envelope, conductors for transmitting electrical energy and data between the elevator car and the elevator hoistway, and one or more load-bearing bearer parts of essentially the length of the travelling cable for fixing the travelling cable at its first end to the elevator car and at its second end to the elevator hoistway, and which bearer part includes glass-fiber reinforcements and/or aramid-fiber reinforcements and/or carbon-fiber reinforcements and/or polybenzoxazole-fiber reinforcements and/or polyethylene-fiber reinforcements and/or nylon-fiber reinforcements in a polymer matrix material. An elevator includes the travelling cable.
摘要:
A cable comprises a first and a second thimble (2, 4), and at least one main yarn (6) and an auxiliary yarn (7). The first and the second thimble are provided at opposite ends of the cable. The at least one main yarn (6) and the auxiliary yarn (7) each forms turns around the first and second thimble (2, 4). Each thimble (2, 4) comprises a bearing surface (40), and holds a stack (19) of layers (10) of turns of the main yarn (6). A stack (119) of turns of the auxiliary yarn (7) comprising at least a first layer (13) of turns of the auxiliary yarn (7) lies on the bearing surface (40) of the respective thimble (2, 4).
摘要:
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.
