钢丝绳破断拉力表之老阳三干创作
我公司经常使用起重钢丝绳型号为6×37+1，公称抗拉强度为170kg/mm2，以下为几种经常使用直径的钢丝绳的破断拉力
钢丝绳破断拉力现场简单估算公式：
S = D2×52
式中S为破断拉力，单位为kg
D为钢丝绳直径，单位为mm
钢丝绳使用平安系数表
钢丝绳拉力计算举例：
1.一根21.5mm钢丝绳，吊装10t重设备，两股受力，是否满足要求？
21.5mm钢丝绳破断拉力为29600kg，平安系数取10，则单股可受力2960kg，两股共5920kg，不克不及满足要求；
反过来计算，现在使用21.5mm钢丝绳四股吊装10t重设备，则单股受力约为2500kg，可计算平安系数为11.84，满足要求。

钢丝绳拉力估算参照表
钢丝绳拉力估算参照表（单根6×29）钢丝绳拉力估算参照表（单根6×37）一、现场估算钢丝绳极限负荷、安全负荷（运用公式：S P=1/2d2，其中d为钢丝绳的直径，单位必须化为英分，1英分=3.175毫米；0.81、0.82为换算系数值；K为安全系数值）：1、现有一根规格为6×37，直径为21毫米的钢丝绳，计算该钢丝绳的破断拉力及允许拉力。
破断拉力S P=1/2d2×0.82=1/2×（21÷3.175）2×0.82=1/2×43.75×0.82=17.94（t）允许拉力S=S P÷K=17.94÷6=2.99（t）2、现有一根规格为6×29+1，直径为33毫米的钢丝绳，计算该钢丝绳的破断拉力及允许拉力。
破断拉力S P=1/2d2×0.81=1/2×（33÷3.175）2×0.81=1/2×108.03×0.81=43.75（t）允许拉力S=S P÷K=43.75÷6=7.29（t）运用口诀：钢丝直径用英分，破断负荷记为吨，直径平方被二除，即为破断负荷数二、当知道吊物重量和钢丝绳角度时，计算钢丝绳的承受拉力（a为吊物重量；n为钢丝绳根数）：例1.某施工现场有一个重16吨的集装箱需要吊运，有四根钢丝绳，钢丝绳与水平方向成45。
角，计算这四根钢丝绳每根在此角度时所承受的拉力。
每根钢丝绳承受拉力S=a/n.1/Sinx=16/4.1/Sin45。
=2.83（t）根据所算的承受拉力参考《估算参照表》可选用合适的钢丝绳例2.某施工现场有重量为5吨的型钢，有两根钢丝绳吊运，钢丝绳与水平方向成50。
角，计算这两根钢丝绳每根在此角度时所承受的拉力。
每根钢丝绳承受拉力S=a/n.1/Sinx=5/2.1/Sin50。
- =1.92（t）说明：钢丝绳的受力大小随着角度的增大而减小，角度的减小而增大，钢丝绳越长，角度越大，反之则越小。

钢丝绳破断拉力表
我公司常用起重钢丝绳型号为6×37+1，公称抗拉强度为170kg/mm2，以下为几种常用直径的钢丝绳的破断拉力
钢丝绳破断拉力现场简单估算公式：
S = D2×52
式中S为破断拉力，单位为kg
D为钢丝绳直径，单位为mm

钢丝绳拉力计算举例：
1.一根钢丝绳，吊装10t重设备，两股受力，是否满足要求
钢丝绳破断拉力为29600kg，安全系数取10，则单股可受力2960kg，两股共5920kg，不能满足要求；
反过来计算，现在使用钢丝绳四股吊装10t重设备，则单股受力约为2500kg，可计算安全系数为，满足要求。
