起重吊裝常用鋼絲繩使用便攜手冊(cè)

1、起重吊裝常用鋼絲繩使用便攜手冊(cè)鋼絲繩選用及計(jì)算方法鋼絲繩類型：常用鋼絲繩依據(jù)繩股與繩的捻向可分為交捻繩、順捻繩和混合捻繩。散，吊裝重物后不會(huì)轉(zhuǎn)動(dòng)。起重吊裝作業(yè)中優(yōu)先使用交捻繩。散和具有扭轉(zhuǎn)的傾向，在自由懸掛重物的吊裝作業(yè)中不宜承受?；旌夏礓摻z繩：綜合順捻和交捻的綜合捻法，鋼絲繩中相鄰兩股或兩層股的鋼交捻順捻混合捻鋼絲繩常用規(guī)格、637+1、661+16619、37、61越好，但耐磨性下降，11619+1：繞性差，常用作拉索、纜風(fēng)繩及制作起重索具。彎狀況下使用。常用于起重吊裝作業(yè)中捆扎、設(shè)備及穿繞滑車組及制作起重吊。637+1繞性好易于彎曲，用于綁扎各類物件。但耐磨性差，常見(jiàn)于受載不大的狀況下使
