钢丝绳破断拉力参数

1、1钢丝绳重量及最小破断拉力计算1.1 重量重量钢丝绳参考重量按下式计算：水D MM -钢丝绳单位长度的参考重量，kg/100m式中：；D -钢丝绳的公称直径， mm;K -充分涂油的某一结构钢丝绳单位长度。2mm kg/100 的重量系数，K值在表1给出。1.2 破断拉力钢丝绳实测破断拉力应不低于表 24的规定。钢丝绳最小破断拉力用kN表示，并按下式计算：2 R DK'F 01000式中：F -钢丝绳最小破断拉力，kN; 0D -; 钢丝绳的公称直径，mmR-钢丝绳公称抗拉强度，；Mpa0K'K'值见表1)-某一指定结构钢丝绳的最小拉力，系数(。-1 -表1钢丝纯重量系
