    • PROBLEM TO BE SOLVED: To provide a multilayer-twisted wire rope that is suitable as a running wire for an elevator or a cargo-handling machine typified by a crane, has flexibility, a thin rope diameter, a light weight, in no need of application or feeding of oil, can realize good friction contact with the sheaves as they retain a needed degree of fatigability, even when the sheave diameter is made smaller and in addition, to provide a multilayer-twisted wire rope particularly having excellent fatigability in addition to the properties sated above. SOLUTION: Wires or strands of few wires twisted are arranged around the covered twisted core prepared by covering the core body formed by twisting high-strength steel wires of which wire radius(WR) is in a specific range with a high molecular compound and the wires or the strands are twisted in plural layers. In the resultant wire rope, the individual intermediate layers are covered with a high molecular compound and the outermost layer is also covered with the high molecular compound. In addition, individual strands on the outer- periphery of the covered core have positively spaces along the circumferential length of the layer center and the individual spaces are filled with the high molecular compound.
    • 要解决的问题:提供适合作为电梯或以起重机为代表的货物处理机的运行线的多层绞合钢丝绳,具有柔软性,细绳直径,重量轻,不需要 油的应用或进料,即使当滑轮直径较小时,也能够保持所需的疲劳程度,可以实现与滑轮的良好的摩擦接触,另外,除了提供特别是具有优异的耐疲劳性的多层扭绞钢丝绳之外, 上述物业。 解决方案:将覆盖的扭绞芯线布置在覆盖的扭绞芯周围,通过覆盖由高分子化合物将电线半径(WR)在特定范围内的高强度钢丝扭绞而形成的芯体, 或者股线以多层扭曲。 在所得的钢丝绳中,各个中间层被高分子化合物覆盖,最外层也被高分子化合物覆盖。 此外,被覆芯的外周上的单个股线沿着层中心的圆周长度具有正空间,并且各个空间用高分子化合物填充。
