由(you)于工作(zuo)(zuo)任務繁重(zhong)橋(qiao)式(shi)(shi)起(qi)重(zhong)機(ji)(ji)使(shi)用頻繁，易造成(cheng)橋(qiao)式(shi)(shi)起(qi)重(zhong)機(ji)(ji)各機(ji)(ji)械傳動系統磨損較為(wei)嚴重(zhong),這就需要(yao)對橋(qiao)式(shi)(shi)起(qi)重(zhong)機(ji)(ji)的各個部位(wei)經常進(jin)行維護保養,使(shi)其發揮(hui)最大工作(zuo)(zuo)效率。橋(qiao)式(shi)(shi)起(qi)重(zhong)機(ji)(ji)電氣控制系統在司機(ji)(ji)室內可同時控制主副鉤(gou)的升降,大小車(che)的運(yun)行機(ji)(ji)構(gou)。
    總控(kong)制(zhi)回(hui)路電(dian)(dian)(dian)源進線開(kai)關(guan)采(cai)用自動空氣開(kai)頭。總空氣開(kai)關(guan)是作為電(dian)(dian)(dian)源起(qi)到一(yi)定的保護作用,只(zhi)有在緊急情況下(xia)才使用緊急按鈕接(jie)通(tong)閘線圈位空氣開(kai)關(guan)跳閘，一(yi)般情況下(xia)，使用電(dian)(dian)(dian)源接(jie)觸(chu)器(qi)分合電(dian)(dian)(dian)源。電(dian)(dian)(dian)源和供(gong)電(dian)(dian)(dian)形式機構上所(suo)有動力回(hui)路和控(kong)制(zhi)回(hui)路均采(cai)用380V交流電(dian)(dian)(dian)電(dian)(dian)(dian)源由(you)角鋼滑線供(gong)電(dian)(dian)(dian)，滑線裝在橋式起(qi)重機駕(jia)駛室正對的一(yi)側。從供(gong)電(dian)(dian)(dian)點(dian)到電(dian)(dian)(dian)機最大壓降(jiang)不(bu)超過額定電(dian)(dian)(dian)壓的3%,否則影響橋機的正常運行。
    橋(qiao)式起重(zhong)機大(da)小車軌道必須按規程可靠接(jie)地(di)。橋(qiao)式起重(zhong)機工作(zuo)照(zhao)明采用500W防(fang)震行車燈(deng)，裝在主梁下面(mian)，由照(zhao)明變壓器(qi)供電，橋(qiao)架內和司機室照(zhao)明采用220V日光燈(deng)，所有照(zhao)明都由照(zhao)明控制(zhi)箱控制(zhi)。
    目前,我國已(yi)經從各(ge)方面進行橋式起重機節(jie)能技術(shu)研(yan)究。而且,“節(jie)能降耗，建設節(jie)約型社會”也是我國宏觀經濟運(yun)行中的一項緊(jin)迫任(ren)務，更(geng)是一項長(chang)期的戰略任(ren)務。
