操作起(qi)重機制動(dong)器(qi)要注意哪些

　　起重機制動器啟(qi)(qi)動(dong)前(qian)，操作人員須按(an)下啟(qi)(qi)動(dong)按(an)鈕，以(yi)保證安全制(zhi)動(dong)器與起重機同時啟(qi)(qi)動(dong)。

　　起重(zhong)機啟動(dong)(dong)(dong)后，安(an)全制(zhi)(zhi)動(dong)(dong)(dong)器(qi)處于常開(kai)狀態，同時工(gong)作制(zhi)(zhi)動(dong)(dong)(dong)器(qi)開(kai)啟負(fu)責起重(zhong)機升降的制(zhi)(zhi)動(dong)(dong)(dong)工(gong)作。起重(zhong)工(gong)作完(wan)成后，及時關(guan)閉工(gong)作制(zhi)(zhi)動(dong)(dong)(dong)器(qi)，相關(guan)操作人員檢查(cha)各事項，無異(yi)常情(qing)況(kuang)則斷開(kai)起重(zhong)機電(dian)源，離開(kai)操作平臺，安(an)全制(zhi)(zhi)動(dong)(dong)(dong)器(qi)同時被(bei)鎖(suo)定，整個起重(zhong)工(gong)作結束。

　　若(ruo)起(qi)(qi)重(zhong)(zhong)機制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)工(gong)作(zuo)(zuo)(zuo)過程中(zhong)發(fa)生(sheng)(sheng)故(gu)(gu)障，操(cao)作(zuo)(zuo)(zuo)人員必(bi)須(xu)(xu)馬(ma)上按(an)(an)下(xia)應急(ji)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)按(an)(an)扭，此時(shi)，工(gong)作(zuo)(zuo)(zuo)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)及安(an)(an)(an)全(quan)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)會相(xiang)繼合閘(zha)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)，安(an)(an)(an)全(quan)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)延遲(chi)約2 ～ 5s，防止安(an)(an)(an)全(quan)事(shi)故(gu)(gu)發(fa)生(sheng)(sheng)。起(qi)(qi)重(zhong)(zhong)機工(gong)作(zuo)(zuo)(zuo)過程中(zhong)發(fa)生(sheng)(sheng)事(shi)故(gu)(gu)時(shi)，操(cao)作(zuo)(zuo)(zuo)人員須(xu)(xu)立刻(ke)按(an)(an)下(xia)緊急(ji)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)按(an)(an)鈕，此時(shi)起(qi)(qi)重(zhong)(zhong)機控(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)電(dian)源立刻(ke)斷開，工(gong)作(zuo)(zuo)(zuo)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)及安(an)(an)(an)全(quan)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)會馬(ma)上合閘(zha)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)，防止事(shi)故(gu)(gu)嚴重(zhong)(zhong)程度的(de)進一步擴(kuo)大。在系統(tong)失電(dian)等特殊情(qing)況下(xia)，需同(tong)安(an)(an)(an)全(quan)事(shi)故(gu)(gu)發(fa)生(sheng)(sheng)時(shi)進行同(tong)樣處理，即按(an)(an)下(xia)緊急(ji)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)按(an)(an)鈕，保證工(gong)作(zuo)(zuo)(zuo)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)及安(an)(an)(an)全(quan)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)的(de)同(tong)時(shi)瞬間合閘(zha)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)。

　　另(ling)一種保證起(qi)(qi)重(zhong)(zhong)(zhong)機制動(dong)(dong)器(qi)(qi)安(an)(an)全性能(neng)的方法是將安(an)(an)全制動(dong)(dong)器(qi)(qi)設置(zhi)為(wei)常開狀(zhuang)態(tai)，起(qi)(qi)重(zhong)(zhong)(zhong)機實施(shi)作(zuo)(zuo)(zuo)(zuo)業過程(cheng)中主要是工作(zuo)(zuo)(zuo)(zuo)制動(dong)(dong)器(qi)(qi)在發揮作(zuo)(zuo)(zuo)(zuo)用(yong)，安(an)(an)全制動(dong)(dong)器(qi)(qi)作(zuo)(zuo)(zuo)(zuo)為(wei)備用(yong)保護(hu)措施(shi)，雙重(zhong)(zhong)(zhong)保證下防止安(an)(an)全事(shi)故的發生。另(ling)外，在起(qi)(qi)重(zhong)(zhong)(zhong)機實施(shi)作(zuo)(zuo)(zuo)(zuo)業過程(cheng)中發生故障或事(shi)故時，工作(zuo)(zuo)(zuo)(zuo)制動(dong)(dong)器(qi)(qi)需(xu)要檢修時，高速檔與低速檔進(jin)行切換時，工作(zuo)(zuo)(zuo)(zuo)制動(dong)(dong)器(qi)(qi)合閘(zha)制動(dong)(dong)，停止工作(zuo)(zuo)(zuo)(zuo)，安(an)(an)全制動(dong)(dong)器(qi)(qi)才會進(jin)入(ru)工作(zuo)(zuo)(zuo)(zuo)狀(zhuang)態(tai)。
