Abstract:
The object of the invention is an elevator, which comprises an elevator car (1), a counterweight (2) and suspension roping (3), which connects the aforementioned elevator car (1) and counterweight (2) to each other, and which suspension roping (3) comprises one or more ropes (R1, R2), which comprise a load-bearing composite part (12), which comprises reinforcing fibers (F) in a polymer matrix (M). The elevator car (1) and the counterweight (2) are arranged to be moved by exerting a vertical force on at least the elevator car (1) or on the counterweight (2). The elevator comprises means (M, 4) separate from the suspension roping (3) for exerting the aforementioned force on at least the elevator car (1 ) or on the counterweight (2).
Abstract:
The invention relates to a method for producing a strand or cable (20), in which fibres (2) and/or wires are twisted on a twisting point (3) to form the strand or cable (20). According to the invention the fibres (2) and/or wires are coated with a liquefied matrix material (4) in front of and/or at the twisting point (3) and are embedded in the matrix material (4) during twisting. The fibres (2) and/or wires are immersed in the matrix material in front of and/or at the twisting point (3) and the formed strand or the formed cable (20) are cooled after the twisting in order for the matrix material (4) to solidify, preferably by air or in a cooling liquid, for example water. The invention further relates to a device for carrying out the method and to a cable which can be produced by means of the method.
Abstract:
Ein Seil umfasst Kohlenstoff enthaltende Filamente, welche jeweils von einer Schlichte ummantelt sind, wobei die von der Schlichte ummantelten Filamente von einer Matrix umgeben sind, wobei die Matrix aus einem wenigstens ein Elastomer und/oder wenigstens ein thermoplastisches Elastomer enthaltendem Material zusammengesetzt ist. Dieses Seil kann insbesondere zum Ziehen einer Last, beispielsweise in einem Lastaufzug, verwendet werden.
Abstract:
Stranded composite cables include a single wire (2) defining a center longitudinal axis, a first multiplicity of composite wires (4) helically stranded around the single wire in a first lay direction at a first lay angle defined relative to the center longitudinal axis and having a first lay length, and a second multiplicity of composite wires (6) helically stranded around the first multiplicity of composite wires in the first lay direction at a second lay angle defined relative to the center longitudinal axis and having a second lay length, the relative difference between the first lay angle and the second lay angle being no greater than about 4°.

Abstract:
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.
