單(dan)梁(liang)(liang)起重(zhong)(zhong)機通常是指單(dan)梁(liang)(liang)橋式(shi)起重(zhong)(zhong)機，橋架的主梁(liang)(liang)多(duo)采用工字型鋼或(huo)鋼型與鋼板的組(zu)合截(jie)面。起重(zhong)(zhong)小車(che)常為手拉葫(hu)蘆、電動葫(hu)蘆或(huo)用葫(hu)蘆作為起重(zhong)(zhong)機的部(bu)件裝配而成(cheng)。一般的單(dan)梁(liang)(liang)起重(zhong)(zhong)機電動葫(hu)蘆手柄接線共(gong)有9根線，這9根線的接線方(fang)式(shi)如何呢？

    首先(xian)需(xu)要明確這9根線(xian)(xian)(xian)(xian)的(de)用途(tu)，其(qi)中有(you)6根分(fen)別是(shi)(shi)上、下、東、南(nan)、西、北六(liu)個方位的(de)控制線(xian)(xian)(xian)(xian)，另外三根分(fen)別是(shi)(shi)電源(yuan)線(xian)(xian)(xian)(xian)、啟(qi)動線(xian)(xian)(xian)(xian)和自鎖(suo)線(xian)(xian)(xian)(xian)。接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)的(de)原則一(yi)般是(shi)(shi)電源(yuan)線(xian)(xian)(xian)(xian)接(jie)(jie)(jie)急停輸(shu)(shu)入線(xian)(xian)(xian)(xian)，輸(shu)(shu)出(chu)線(xian)(xian)(xian)(xian)接(jie)(jie)(jie)停止(zhi)(zhi)線(xian)(xian)(xian)(xian)，停止(zhi)(zhi)輸(shu)(shu)出(chu)線(xian)(xian)(xian)(xian)接(jie)(jie)(jie)啟(qi)動輸(shu)(shu)入線(xian)(xian)(xian)(xian)。

    接著(zhu)需要安裝起重機再安裝拉線鋼絲(si)繩，等到電(dian)源線固定好(hao)后，三根(gen)(gen)線分別接下邊一(yi)排接線端(duan)左邊的三個螺絲(si)上，接好(hao)后要進(jin)行試機，若發現接線方(fang)向相反要任(ren)意對調其中(zhong)的兩(liang)根(gen)(gen)線再進(jin)行試機。

    駕駛室、控制(zhi)箱內的(de)配(pei)線(xian)連接時(shi)需要對控制(zhi)回路選用塑料絕緣導(dao)線(xian)進(jin)行配(pei)線(xian)，根據需要的(de)數量(liang)和長度(du)加一定(ding)的(de)備(bei)用線(xian)，然后一起穿入(ru)電線(xian)管(guan)(guan)，根據電路圖(tu)和接線(xian)圖(tu)對穿管(guan)(guan)后的(de)導(dao)線(xian)進(jin)行校(xiao)線(xian)、套(tao)(tao)線(xian)號、接線(xian)，在電線(xian)管(guan)(guan)進(jin)、出口處(chu)應套(tao)(tao)絕緣塑料管(guan)(guan)進(jin)行保護(hu)。
