    Abstract: A bolt (10,20) for use in the reinforcing of formations (S) comprises a plurality of first wires (14) arranged around a core (12) in a first lay direction along a length of the core, and a plurality of second wires (16) arranged around the first wires in a second different lay direction along the core length. A third layer of wires (22) can be provided in a different or same lay direction as the first or second layer. The core can comprise a tube (eg. of a steel or polymer) that has sufficient flexibility such that it can be bent in an arcuate manner. This can provide flexibility to the bolt. A method of forming and a method of installing the bolt are disclosed, as is a system which employs two or more bolts which have in-use protruding portions that can be fastened together.

    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 。

    Abstract: Bei einem durch eine Seilscheibe angetriebenen Treibseil, mit einem Seilkern (19) aus in konzentrischen Litzenlagen (14, 16) miteinander parallelverseilten tragenden Aramidfaserlitzen (9, 10, 11), wird vorgeschlagen, die Litzen (12) einer äussersten Litzenlage (12) im Gegenschlag mit dem Seilkern (19) zu verseilen. Durch die Gegenschlagverseilung heben sich die unter Last in den Litzenlagen (14, 16, 21) entstehenden Drehmomente gegenseitig auf; es wird ein drehungsneutraler Seilaufbau erreicht. Ein elastischer Zwischenmantel (20) zwischen den gegenschlagverseilten Litzenlagen (16, 21) dient als Abriebschutz für die Litzen (10, 11, 12) und einer grossflächigen Drehmomentenübertragung im Aufzugsseil (1).

    Abstract: The present invention provides structure of steel cord in heavy duty tires, in which the adhesive strength between filament and rubber, and penetrating property of rubber are improved by making the twist direction of core and strand different in the steel cord comprising core and strand filament, and by making the pitch or the twist period of core and strand different. In particular, this structure is applied to steel cord of 3+8*d(HT) which is used in heavy duty tires. In this application, twist direction of core filament is in the S direction and twist direction of strand filament is in the Z direction, and the ratio of the pitch of core filament (CP) and the pitch of strand filament (SP) is between 0.50 and 0.94.
