1.卷揚組織有必(bi)要裝有過卷揚限(xian)制器，當吊(diao)鉤(gou)滑車起(qi)升距起(qi)重(zhong)組織架300mm時，能夠(gou)主動(dong)堵截電(dian)機(ji)(ji)的電(dian)源，電(dian)動(dong)機(ji)(ji)中止作業(ye)。是避免起(qi)重(zhong)機(ji)(ji)駛(shi)近軌(gui)跡結尾(wei)而發作碰擊事端(duan)(duan)，或兩臺起(qi)重(zhong)機(ji)(ji)在同一條軌(gui)跡上發作磕碰事端(duan)(duan)，所采納的安(an)全設備。

2.主(zhu)動聯鎖(suo)設(she)備是橋(qiao)式起(qi)(qi)重(zhong)(zhong)機(ji)上多有(you)裸線經(jing)過，為了(le)避(bi)免維修人員觸電，需求在駕駛室通往車駕的倉門口處裝(zhuang)設(she)主(zhu)動連鎖(suo)設(she)備。緩沖器是一種吸收起(qi)(qi)重(zhong)(zhong)機(ji)與物體(ti)相碰時的能量(liang)的安(an)全設(she)備，在起(qi)(qi)重(zhong)(zhong)機(ji)的制動器和結尾開關失靈后起(qi)(qi)效果。當起(qi)(qi)重(zhong)(zhong)機(ji)與軌跡端(duan)頭(tou)立柱相接(jie)時，（廣東(dong)起(qi)(qi)重(zhong)(zhong)設(she)備）確保(bao)起(qi)(qi)重(zhong)(zhong)機(ji)較(jiao)平穩(wen)地(di)泊車。

3.制動(dong)器(qi)，能(neng)使(shi)起(qi)重(zhong)設備在(zai)升降、平移(yi)和旋轉過程中隨時中止(zhi)作業和使(shi)重(zhong)物停(ting)留在(zai)任何高度(du)上的(de)一種設備，它即能(neng)避免意外事端，又(you)能(neng)滿意作業需求。因為(wei)制動(dong)器(qi)的(de)效果關于起(qi)重(zhong)機來說十分(fen)重(zhong)要，許多事端的(de)發作往(wang)往(wang)是因為(wei)制動(dong)器(qi)的(de)失靈或發作拍(pai)手而(er)形成(cheng)的(de)。
