In the aforementioned rope installation the elevator is reeved to comprise construction-time hoisting roping (3,3')/ which comprises one or more ropes, the longitudinal power transmission capacity of which is based at least essentially on non-metallic fibers in the longitudinal direction of the rope. In the method guide rails (G) to be fixed with guide rail brackets (b) can additionally be installed by the aid of installation means (8,9). The invention also relates to an elevator arrangement, with which the aforementioned method can be performed.

Elevator, which comprises at least an elevator car (C) and means for moving the elevator car, preferably along guide rails (G), and an overspeed governor arrangement, which comprises an overspeed governor rope (R,R',R''), which moves according to the movement of the elevator car, and which overspeed governor rope (R,R',R'') is connected to a brake arrangement that is in connection with the elevator car (C) such that with the overspeed governor rope (R,R',R'') force can be transmitted to the brake arrangement for shifting the brake (SG) comprised in the brake arrangement into a braking position. The rope comprises a power transmission part (2) or a plurality of power transmission parts (2), for transmitting force in the longitudinal direction of the rope, which power transmission part (2) is essentially fully of non-metallic material.
Abstract:
One aspect of this invention concerns a multi-strand steel wire rope (28, 32, 36, 46, 50) comprising multiple strands (3, 10, 38) laid up helically on a core (30, 34, ), characterised in that at least some of the strands are deep strands (10, 38), i.e. strands with a heightwidth ratio greater than unity. Another aspect of the invention concerns the deep strand (10, 38) itself.
Abstract:
A method for manufacturing a hoisting rope (R,R',R",R'") is disclosed, comprising the steps of providing a plurality of elongated composite members (1,1',1",1"'), which composite members (1,1',1",1 "') are made of composite material comprising reinforcing fibers (f) in polymer matrix (m); and arranging the composite members (1,1',1",1"') to form an elongated row (r,r',r",r"') of parallel composite members 1,1',1",1"' , which row (r,r',r",r"') has a longitudingal direction (L), a thickness direction (T) and a width direction (W), and in which row (r,r',r",r"') the composite members (1,1',1",1 "') are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction (W) of the row (r,r',r",r"'); and directing plasma treatment on the outer surface of the composite members (1,1',1",1"'); and embedding the composite members (1,1',1",1'") in fluid polymer material (2); and solidifying the polymer material wherein the composite members (1,1',1 ",1 "') are embedded. The invention relates also to a hoisting rope onbtained with the method and an elevator comprising the hoisting rope. An elevator load bearing belt obtained by said method is also disclosed.
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:
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:
A braided hose reinforcement comprises left and right turning strips. Each of said strips comprises a number of elongated metal elements embedded in a matrix of a polymer material.
Abstract:
The invention concerns a method which consists in forming subassemblies (6) by assembling pultruded strands (5) consisting of traction resistant fibres embedded in a resin, and coating the assembled strands in a protective plastic jacket (7). Said subassemblies are wound on transport reels (12). On a manufacturing site preferably located on the sea front, the tether (4) is formed by assembling the subassemblies unwound from the transport reels, and by coating the assembled subassemblies in an outer plastic sheath (9). The resulting tethers can then be transported to the platform for anchoring the latter.
Abstract:
A steel cord for rubber reinforcement comprises a first group of core filaments having a number of m and a second group of sheath filaments having a number of n, m is three or four, the core filaments are forming a helix, the core filaments are not twisted together and being substantially parallel or the core filaments have a twist pitch being more than 300mm; the second group and the first group are twisted around each other, and the sheath filaments are forming a flattened helix in the same direction of the helix of the core filaments, and the sheath filaments have a cord twist pitch, at any cross-section of the steel cord, at least one interstice between two adjacent core filaments is present. The steel cord has improved abrasion resistance and can contribute to the reduction of the weight of the tire.
