    Abstract: A wire rope for a heavy-load crane, such as a ladle crane is provided that is not only almost rotation-resistant but is also unlikely to be broken by wear and fatigue of wires. The rotation-resisting wire rope (1) has a plurality of side strands (3). In side each strand (3), wires (5) are laid in the same direction as the lay of core strand wires (4), around the periphery of a core strand (2). The side strands (3) are laid in a direction opposite to the lay of the core strand wires (4) so as to form the wire rope (1). The side strands (3) preferably have a smaller pitch multiple than a pitch multiple of the wire rope (1). The ratio between a diameter (d2) of the side strands (3) and a diameter (d1) of the core strand (2) is preferably about 1.3 to about 1.8. The pitch multiple of strands (3) is preferably about 5 to about 8 and the pitch multiple of the wire rope (1) is preferably about 8 to about 10. Both the core strand (2) and the side strands (3) preferably have shaped wires (4,5), having a flattened surface, at an outermost ply.

    Abstract translation: 提供用于重型起重机的钢丝绳，例如钢包起重机，其不仅几乎具有抗旋转性，而且也不太可能被电线的磨损和疲劳破坏。 耐旋转钢丝绳具有多个侧股。 在每根股线的侧面，电线沿与芯股线的周围相同的方向被放置在与芯线股线相同的方向上。 侧股线以与芯股线的铺设方向相反的方向铺设，以形成钢丝绳。 侧股优选具有比钢丝绳的节距倍数更小的节距倍数。 侧股直径与芯股直径之比优选为1.3〜1.8左右。 线的间距倍数优选为约5至约8，并且钢丝绳的节距倍数优选为约8至约10.芯股和侧股优选具有扁平表面的成形线，在最外层 。

    Abstract: A steel cord (1) having a three-layer twisted construction consisting of an innermost layer (2), an intermediate layer (3), an outermost layer (4), and a spiral wrap (5) and being capable of achieving an improvement in the adhesion force to rubber while reducing the number of processing steps used. In the steel cord (1), the innermost layer (2) consists of 3 filaments (2a) twisted in one of left or right twist directions while having a twist pitch length of 5 to 18mm; the intermediate layer (3) consists of 8 filaments (3a) twisted in the same twist direction as that of the innermost layer (2) while having a twist pitch length of 5 to 18mm, namely, the same twist pitch length as that of the innermost layer (2); the outermost layer (4) consists of 13 filaments (4a) twisted in a left or right twist direction opposite to those of the innermost and intermediate layers (2,3) while having a twist pitch length of 10 to 25mm equal to or more than those of the innermost and intermediate layers (2,3); and the spiral wrap (5) consists of a single filament adapted to be wrapped around the outermost layer (4), thereby preventing the steel cord (1) from being unwound, the filament being twisted in a twisted direction opposite to that of the outermost layer (4) while having a twist pitch length of 3 to 10mm. Gaps are formed among the filaments (3a,4a) of the intermediate and outermost layers (3,4). The gaps allow rubber to penetrate easily into the steel cord (1) therethrough.

    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.
