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+FC6VX34+FC
