    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 translation: 目的：提供一种重型起重机的钢丝绳，例如钢丝绳起重机，其是非旋转的，但是由于电线的磨损和疲劳而不易断裂，这可以延长电线的使用寿命，即使当钢丝绳应用于 钢厂的高负载起重机发生反复弯曲。 构成：该钢丝绳（1）包括芯线（2），其包括在第一层方向上层叠的多根芯线，以及沿着第二层方向层叠在芯股线上的多个侧股（3） 第一层方向，并且其每条侧股包括在第一层方向上层叠的侧股线，并且具有比钢丝绳的间距更小的节距倍数，其中芯股直径与侧股的比率约为 1.3至1.8。 绞线的节距倍数优选为约5至约8，并且钢丝绳的节距倍数优选为约8至约10。
