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）此公式二十年前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。QQQQQQQQQQQQQQQQQQQQQQQQ一般矿井用钢丝绳有以下种类：1 、斜井提升用 6X7+FC 和 6TX7+FC(面接触）、6X19S+FC 和6TX19S+FC、6VX19+FC；2、竖井卷扬提升一般用 6X26WS+FC 6X36WS+FC 18X7+FC 6VX3
