橋式起重機修理的訣竅

 

    (1)在起重機的安全保護中，對艙口門、司si機ji室shi門men和he檢jian修xiu門men上shang均jun有you一yi個ge門men開kai關guan
，當dang起qi重zhong機ji司si機ji或huo維wei修xiu人ren員yuan到dao起qi重zhong機ji上shang進jin行xing檢jian修xiu時shi，必bi須xu打da開kai艙cang口kou門men到dao起qi重zhong機ji走zou台tai上shang，或huo打da開kai檢jian修xiu門men到dao起qi重zhong機ji軌gui道dao梁liang上shang
，這zhe時shi打da開kai的de門men上shang電dian器qi開kai關guan的de常chang閉bi觸chu點dian斷duan開kai
，電dian氣qi箱xiang的de主zhu接jie觸chu器qi釋shi放fang，進jin而er切qie斷duan起qi重zhong機ji電dian源yuan，使shi起qi重zhong機ji無wu法fa起qi動dong。吊diao車che修xiu理li同tong時shi這zhe種zhong保bao護hu使shi檢jian修xiu人ren員yuan免mian受shou橋qiao架jia上shang小xiao車che滑hua線xian帶dai電dian的de威wei脅xie，也ye可ke防fang止zhi他ta人ren起qi動dong開kai車che傷shang及ji檢jian修xiu人ren員yuan。可ke見jian安an全quan門men開kai關guan的de保bao護hu作zuo用yong非fei常chang必bi要yao。

 

    (2)將觸點更換為新的，不起動問題得到解決。從凸輪控製器的結構可知，隻有在各控製器手柄置於零位時，起升、小車和大車控製器的零位觸頭才閉合。而在其它任何工作位置(即非零位置)時
，都處於斷開位置。吊車修理因此
，當任何一控製器手柄不在零位(或零位觸點沒有閉合)shi
