    Abstract: 거의 비 자전성일 뿐만 아니라 와이어의 마모 및 피로에 의해서 쉽게 파손되지도 않는 레이들 크레인과 같은 고하중의 크레인을 위한 와이어 로프가 제공된다. 이 비 자전 와이어 로프는 복수의 사이드 스트랜드를 갖는다. 각 사이드 스트랜드에 있어서, 와이어는 코어 스트랜드의 둘레에 코어 스트랜드 와이어와 동일 방향으로 꼬아진다. 사이드 스트랜드는 코어 스트랜드 와이어의 꼬임과 반대 방향으로 꼬아져서 와이어 로프를 형성한다. 사이드 스트랜드는 와이어 로프의 피치배수보다 작은 피치배수를 갖는 것이 바람직하다. 사이드 스트랜드의 직경과 코어 스트랜드의 직경 간의 비는 약 1.3 내지 약 1.8인 것이 바람직하다. 스트랜드의 피치배수는 약 5 내지 약 8인 것이 바람직하고, 와이어 로프의 피치배수는 약 8 내지 약 10인 것이 바람직하다. 코어 스트랜드와 사이드 스트랜드의 양자는 최외측 층에 편평한 표면을 갖는 성형 와이어를 구비하는 것이 바람직하다.

    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: PROBLEM TO BE SOLVED: To provide a bead wire which sufficiently prevents deformation and breakage of a bead core cross section, and saves weight of a tire, to provide a bead core using the bead wire, and to provide a pneumatic tire using the bead core.SOLUTION: A bead wire which has an approximately regular hexagonal shape in cross section and has at least one hollow part in the cross section is provided. The hollow part has an approximately circular shape in cross section. A bead core is formed by stacking the plural bead wires so that adjacent bead wires come surface-contact with each other. A pneumatic tire equipped the bead core is provided.
