Abstract:
Câble de traction et de levage (1) comprenant des torons métalliques internes (2) torsadés entre eux, et au moins une couche de torons métalliques externes (4) torsadés autour desdits torons métalliques internes (2), chaque toron métallique externe (4) comprend une âme centrale (5) en matière plastique déformable. Selon l'invention, lesdits torons métalliques externes (4) sont écrasés et aplatis, de manière ordonnée, et les fils (4a) constitutifs de chaque toron externe (4) sont agencés selon au moins deux couches, en contact l'une avec l'autre, et en alignement par rapport aux au moins deux couches correspondantes des torons externes (4) adjacents, ladite âme centrale (5) de chaque toron externe (4) ayant migrée afin de remplir les interstices présents entre lesdites deux couches et entre lesdits fils (4a) constitutifs de chaque toron externe (4).
Abstract:
A rope (210, 310) having a three-layered structure comprising a core layer, an inner layer and an outer layer, the core layer comprising one strand (225, 315), the inner layer comprising multiple strands (220) with an amount n and the outer layer comprising multiple strands (215) with an amount m, wherein n is an uneven number, and m is a number which has no common divisor with n, each strand is formed by multiple twisted metal filaments. By this structure fretting of the strands is reduced and the life time of the rope is improved. Also, the use of the rope in lifting application and an elevator system comprising such a rope are disclosed.
Abstract:
The present invention relates to a hybrid cord comprising an inner layer (1) in steel cord, an intermediate layer (2) in a high module and high toughness fibre and an outer layer (3) in a Polyolefin fibre. The present invention also refers to its application in an 8 (4x2) cords braided hybrid cable or any other type of hybrid cable presenting another construction, in braided or twisted cables.
Abstract:
A thin buffer layer (303) is used to coat on the multi-filament (401) wrapped string to fill the gaps. The polymers of the buffer-layer coating have a high melt-flow (low viscosity) during coating process to fill all the gaps between the filaments, and the filaments are fixed by the coatings onto base core materials.
