不旋轉(zhuǎn)鋼絲繩也叫多層股不旋轉(zhuǎn)或者微旋轉(zhuǎn)鋼繩，以其再吊裝時不容易使貨物因重力自轉(zhuǎn)得名，典型的結(jié)構(gòu)有18*7、19*7、34*7、35W*7、19*K7、35W*K7其他如15*K7、34*7、36*7、4V*39S，如下圖，多層股中，內(nèi)層股和外層股分別處于不同的旋轉(zhuǎn)方向，左右力相互抵消，從而在工作中可以釋放掉部分扭轉(zhuǎn)力，達到不旋轉(zhuǎn)或者微旋轉(zhuǎn)的功效。
多層股不旋轉(zhuǎn)（光面、鍍鋅）
·適用于塔吊，立井提升、立井平衡、
立井罐道及索道承重、石油鉆井等 |
