Abstract:
PURPOSE: A wire rope for a heavy-load crane such as a ladle crane which is irrotational but difficult to be broken by wear and fatigue of wires is provided, which can extend the service life of wires remarkably even when the wire rope is applied to a high-load crane in a steel mill and repeated bending is occurred. CONSTITUTION: This wire rope(1) comprises core strands(2) including a plurality of core strand wires laminated in the first layer direction and a plurality of side strands(3) laminated around the core strands in the second layer direction as the opposite of the first layer direction, and each side strand of which includes side strand wires laminated in the first layer direction and has a smaller pitch multiple than that of the wire rope, wherein the ratio of a diameter of the core strands to the side strands is about 1.3 to 1.8. The pitch multiple of strands is preferably about 5 to about 8 and the pitch multiple of the wire rope is preferably about 8 to about 10.

Abstract:
The present invention is to provide a hybrid core rope (1) which does not require maintenance or a hybrid core rope (1) capable of reducing a maintenance task. The hybrid core rope (1) includes a resin solid core (2) in which a plurality of spiral grooves (2a) is formed in the longitudinal direction on an outer peripheral surface thereof, a plurality of fiber bundles (3) respectively spirally wound around the outer peripheral surface of the resin solid core (2) along the plurality of spiral grooves (2a), the fiber bundles (3) having thickness to fill the spiral grooves (2a), and a plurality of steel strands (4) spirally wound around the outer peripheral surface of the resin solid core (2) around which the fiber bundles (3)are wound. The fiber bundles (3) and the strands (4) are respectively wound so as to have angles which are not parallel to each other.
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.
