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:
La présente invention concerne un câble métallique à trois couches de construction L+M+N utilisable comme élément de renforcement d'une armature de carcasse de pneumatique, comportant une couche interne C 1 à L fils de diamètre d, avec L allant de 1 à 4, entourée d'une couche intermédiaire C2 à M fils de diamètre d 2 enroulés ensemble en hélice selon un pas P 2 avec M allant de 3 à 12, ladite couche C2 étant entourée d'une couche externe C3 de N fils de diamètre d 3 enroulés ensemble en hélice selon un pas p3 avec N allant de 8 à 20, ledit câble étant caractérisé en ce qu'une gaine constituée d'une composition de caoutchouc réticulable ou réticulée à base d'au moins un élastomère diénique recouvre au moins ladite couche C2. L'invention concerne en outre les articles ou produits semi-finis en matière plastique et/ou en caoutchouc renforcés par un tel câble multicouches, notamment les pneumatiques destinés aux véhicules industriels, plus particulièrement les pneumatiques Poids-lourd et leurs nappes d'armature de carcasse.
