同样直径的钢丝绳单绳拉力视钢丝绳的抗拉强度、型号不同而有区别。
以直径11mm,规格为6x37+FC钢丝绳为例：
抗拉强度为1770MPa时，其最小破断拉力是63.1KN。
抗拉强度为1870MPa时，其最小破断拉力是66.7KN。
实际使用时，最小破断拉力还要除以安全系数。

钢丝绳直径X钢丝绳直径X50/1000=钢丝绳的破断拉力（T）
24X24X50/1000=28.8T
我们在实际的工作中要计算安全系数,所以要除以安全系数4~6
24X24X50/1000=28.8T,比如除以5 28.8T/5=5.76T
安全系数越高,吊的越少。
常见型号钢丝绳破断拉力计算公式：
钢丝绳破断拉力数据在钢丝绳日常使用中起到很大的作用。
每种结构、每种规格的钢丝绳都有其规定的拉力系数，下表列出的就是常见的钢丝绳破断拉力计算方法。表中KN为千牛，除以9.8为千牛换算成吨。
当然另外还要除以相应的安全系数才是正常使用中的安全破断拉力数据。

1，起重吊运钢丝绳的破断拉力慨约计算公式：钢丝绳直径(mm)的平方乘以50等于破断拉力（公斤）此公式是在一本起重机方面的书上学的，工作中运用较方便。对照钢丝绳表查，基本上符合6乘19纤维芯钢丝绳公称抗拉强度1670兆帕的钢丝绳最小破断拉力。起重吊运用时应将破断拉力除以安全系数6倍等于安全负荷。 2，公式为 F0=K'DDR0/1000 F0是最小破断拉力 K'是某绳的破断拉力系数 DD是直径的平方 RO是某绳的公称抗拉强度 单位MPA
