    Abstract: Provided are a steel cord for reinforcing rubber whose fatigue resistance is increased more than ever to enable achieving high durability that was not conventionally realized, and a pneumatic radial tire including the steel cord as a reinforcement member.
    In a steel cord for reinforcing rubber having a double-twist structure that includes a plurality of strands twisted together in the same direction with the same pitch and including a central structure and at least one outer layer, the central structure is composed of at least two strands being twisted around each other and each being composed of at least seven filaments being twisted together. In a steel cord for reinforcing rubber including at least three core strands being twisted together and at least six sheath strands being twisted together around the core strands, the core strands and the sheath strands are twisted in the same direction.

    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 has a plurality of side strands. In side each strand, wires are laid in the same direction as the lay of core strand wires, around the periphery of a core strand. The side strands are laid in a direction opposite to the lay of the core strand wires so as to form the wire rope. The side strands preferably have a smaller pitch multiple than a pitch multiple of the wire rope. The ratio between a diameter of the side strands and a diameter of the core strand is preferably about 1.3 to about 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. Both the core strand and the side strands preferably have shaped wires, having a flattened surface, at an outermost ply.

    Abstract translation: 提供了用于重载起重机如钢包起重机的钢丝绳，该钢丝绳不仅几乎不旋转，而且也不易因钢丝的磨损和疲劳而断裂。 防旋钢丝绳具有多个侧股。 在每根钢绞线的侧面，钢丝以与芯绞线的绞合线相同的方向围绕绞合线的外围铺设。 侧股以与芯股绞合线相反的方向铺设以形成钢丝绳。 侧线优选具有比钢丝绳的节距倍数更小的节距。 侧股直径与芯股直径之比优选为约1.3至约1.8。 绳索的节距倍数优选为大约5至大约8，并且钢丝绳的节距倍数优选为大约8至大约10.芯部绳股和侧部绳股优选地具有在最外层处具有扁平表面的成形金属丝 。
