用于滑车组和制作千斤绳（吊索）以及绑扎吊起构件（重物）二钢丝绳的受力及安全系数钢丝绳的受力计算表1-9钢丝绳的容许拉力，可由下式求得：T=c×P/K(N)式中：P——产品规格所保证或试验所得的钢丝绳破断拉力（N），如P采用钢丝破断拉力总和，则须乘“换算系数”；K——钢丝绳的安全系数，可按表1-10采用c—钢丝绳的换算系数钢丝绳的安全系数K表1-10 使用情况 K值 使用情况 K值 用于缆风绳 3.5 用作千斤绳，无弯曲时 6~7 用于手动起重设备 4.5 用作绑扎的千斤绳 8~10 用于机动起重设备 5~6 用于载人的提升机 14换算系数c按钢丝绳规格而定：表1-11 钢丝绳规格 6×19+1 6×37+1 6×61+1 换算系数c 0.85 0.82 0.80钢丝绳的钢丝强度，按国家 标准
