用于提升的绳索以及包括该绳索的升降机
摘要：
一种绳索(210、310)有包括芯层、内层和外层的三层结构，芯层包括一根股线(225、315)，内层包括数量为n的多根股线(220)，外层包括数量为m的多根股线(215)，其中，n是奇数，而m是与n没有公约数的数，各股线由多根加捻的金属丝形成。通过这种结构，股线的磨损减小，绳索的使用寿命提高。还公开了这种绳索在提升用途中的应用以及具有这种绳索的升降机系统。
摘要（英）：

A rope (210, 310) having a three-layered structure comprising a core layer, an inner layer and an outer layer, the core layer comprising one strand (225, 315), the inner layer comprising multiple strands (220) with an amount n and the outer layer comprising multiple strands (215) with an amount m, wherein n is an uneven number, and m is a number which has no common divisor with n, each strand is formed by multiple twisted metal filaments. By this structure fretting of the strands is reduced and the life time of the rope is improved. Also, the use of the rope in lifting application and an elevator system comprising such a rope are disclosed.
