    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord for reinforcing a rubber article, by preventing the preceding breakage of filaments and improving the strength at break of the steel cord as a whole, and to provide a pneumatic tire using the same.
    SOLUTION: This double-twisted structure steel cord is provided by twisting a core filament 11 with at least one layer sheath filaments 21 as a layer-twisted structure to form one strand, further twisting in a plurality of strands as the layer-twisted structure consisting of a core strand 1 and at least one layer of sheath strands 2 to make one steel cord. The tensile strength of the filament for forming the strand is made as "the tensile strength of the filament in a layer close to the center of the strand"≥"the tensile strength of the filament in a layer far from the center of the filament", and the mean tensile strength of the strand for forming the steel cord is made as "the mean tensile strength of the layer close to the center of the steel cord"

    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 (10) has a diameter D and comprises a core strand (12) and up to nine peripheral strands (14) surrounding the core strand. The core strand (12) has a diameter D1 and the peripheral strands (14) have a diameter D2. The ratio core strand diameter to peripheral strand diameter D1/D2 is greater than a predetermined value in order to enable rubber penetration. Each strand comprises a centre of one or more centre filaments (16,22) and two or more layers of filaments (18,20,24,26) surrounding the centre.
    The twist angle of a radially outer layer is smaller than the twist angle of a radially inner layer of the same strand. A first free space (28) ranging from 0.0015xD to 0.0075xD is provided in at least the core strand (12) between each pair of filaments (18) of the radially most inner layer.
