前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T26722—2022《索道用鋼絲繩》，與GB/T26722—2022相比，除結(jié)構(gòu)調(diào)整和編輯

性改動(dòng)外，主要技術(shù)變化如下：

——增加了6×49SWS、6×55SWS、6×K49SWS和6×K55SWS等4個(gè)鋼絲繩典型結(jié)構(gòu)（見表1）；

——更改了6×36WS、6×K36WS等2個(gè)結(jié)構(gòu)鋼絲繩的直徑范圍（見表1，2022年版的表1）；

——?jiǎng)h除了彈性模量相關(guān)要求（見2022年版的7.7和8.1.5）；

——更改了鋼絲繩直徑測(cè)量方法（見8.1.1.3，2022年版的8.1.1.3）；

——?jiǎng)h除了鋼絲繩伸長率和彈性模量試驗(yàn)方法（見2022年版的附錄D）。

請(qǐng)注意本文件的某些內(nèi)容可能涉及專利。本文件的發(fā)布機(jī)構(gòu)不承擔(dān)識(shí)別專利的責(zé)任。

本文件由中華人民共和國工業(yè)和信息化部提出并歸口。

本文件及其所代替文件的歷次版本發(fā)布情況為：

——2011年首次發(fā)布為GB26722—2011；

——2022年第一次修訂為GB/T26722—2022；

——本次為第二次修訂。
