鋼絲繩在各工業(yè)國家中都是標(biāo)準(zhǔn)產(chǎn)品，可按用途需要選擇其直徑、繩股數(shù)、每股鋼絲數(shù)、抗拉強(qiáng)度和足夠的安全系數(shù)，它的規(guī)格型號(hào)可在有關(guān)手冊(cè)中查得。鋼絲繩除外層鋼絲的磨損外，主要因繞過滑輪和卷筒時(shí)反復(fù)彎曲引起金屬疲勞而逐漸折斷，因此滑輪或卷筒與鋼絲繩直徑的比值是決定鋼絲繩壽命的重要因素。比值大，鋼絲彎曲應(yīng)力小，壽命長，但機(jī)構(gòu)龐大。必須根據(jù)使用場(chǎng)合確定適宜的比值。鋼絲繩表面層的磨損、腐蝕程度或每個(gè)擰距內(nèi)斷絲數(shù)超過規(guī)定值時(shí)應(yīng)予報(bào)廢。
鋼絲繩主要用在吊運(yùn),拉運(yùn)等需要高強(qiáng)度線繩的運(yùn)輸中。
