關鍵件(jian)配(pei)置(zhi)(zhi)。主(zhu)要(yao)部件(jian)的(de)(de)好(hao)壞關系到(dao)整車(che)的(de)(de)性能，它是汽車(che)起(qi)重機(ji)(ji)良好(hao)運(yun)行(xing)的(de)(de)基礎。在(zai)(zai)選(xuan)購(gou)汽車(che)起(qi)重機(ji)(ji)時要(yao)對同(tong)(tong)(tong)類(lei)(lei)型(xing)汽車(che)起(qi)重機(ji)(ji)進行(xing)比較quan面的(de)(de)調查(cha)、多方(fang)比較，同(tong)(tong)(tong)一噸位也(ye)存在(zai)(zai)不(bu)(bu)同(tong)(tong)(tong)類(lei)(lei)型(xing)的(de)(de)產品(pin)，要(yao)比較各(ge)型(xing)號(hao)產品(pin)的(de)(de)優勢和劣(lie)勢，做到(dao)胸有成竹。另(ling)外同(tong)(tong)(tong)類(lei)(lei)型(xing)汽車(che)起(qi)重機(ji)(ji)有不(bu)(bu)同(tong)(tong)(tong)的(de)(de)配(pei)置(zhi)(zhi)，用(yong)(yong)戶可(ke)根(gen)據需(xu)要(yao)選(xuan)用(yong)(yong)不(bu)(bu)同(tong)(tong)(tong)的(de)(de)配(pei)置(zhi)(zhi)，當然在(zai)(zai)選(xuan)用(yong)(yong)不(bu)(bu)同(tong)(tong)(tong)配(pei)置(zhi)(zhi)時，液壓支柱制造(zao)商，價格(ge)也(ye)不(bu)(bu)盡相同(tong)(tong)(tong)，用(yong)(yong)戶應根(gen)據自(zi)己的(de)(de)需(xu)要(yao)進行(xing)配(pei)置(zhi)(zhi)，追求zui好(hao)的(de)(de)價格(ge)性能比。

在所有機構運行過(guo)程中，液(ye)壓系(xi)統起著至(zhi)關(guan)重要(yao)的(de)(de)作用，液(ye)壓系(xi)統的(de)(de)關(guan)鍵件包括主(zhu)(zhu)液(ye)壓泵、主(zhu)(zhu)控(kong)(kong)制(zhi)(zhi)閥(fa)、支腿操(cao)(cao)縱(zong)閥(fa)、主(zhu)(zhu)副卷(juan)揚和回轉減速機等，主(zhu)(zhu)液(ye)壓泵由底(di)盤(pan)發動(dong)機驅動(dong)，菏澤液(ye)壓支柱，主(zhu)(zhu)控(kong)(kong)制(zhi)(zhi)閥(fa)分別控(kong)(kong)制(zhi)(zhi)回轉、伸縮(suo)、變(bian)幅及卷(juan)揚作業(ye)動(dong)作，支腿操(cao)(cao)縱(zong)閥(fa)通過(guo)底(di)盤(pan)單側或兩側操(cao)(cao)縱(zong)桿控(kong)(kong)制(zhi)(zhi)支腿同(tong)時或單獨(du)工(gong)作。上車操(cao)(cao)縱(zong)方式(shi)有手(shou)柄操(cao)(cao)作和電液(ye)先(xian)導控(kong)(kong)制(zhi)(zhi)，電液(ye)先(xian)導控(kong)(kong)制(zhi)(zhi)是目前國內(nei)為的(de)(de)操(cao)(cao)縱(zong)方式(shi)。

、司機在收(shou)到(dao)指揮人員(yuan)發出的起(qi)吊信號(hao)后，液壓(ya)支柱報價，必須先鳴信號(hao)后動(dong)作。起(qi)吊重(zhong)物時應先離地面試吊，當確(que)認重(zhong)物掛牢、制動(dong)性能良好和起(qi)重(zhong)機穩定后在繼續起(qi)吊。

七、起吊重(zhong)物時，吊鉤鋼絲繩應保持垂直，禁止吊鉤鋼絲繩在(zai)(zai)傾斜狀態(tai)下去拖動(dong)被吊的(de)重(zhong)物。在(zai)(zai)吊鉤已掛上但(dan)被吊重(zhong)物尚未提起時，禁止起重(zhong)機移動(dong)位置(zhi)或作旋轉(zhuan)運(yun)動(dong)。

八、重物起吊、旋轉時(shi)(shi)，速(su)度(du)要(yao)均(jun)勻(yun)平(ping)穩，以(yi)免重物在(zai)空(kong)中(zhong)擺(bai)動(dong)發生(sheng)危險。在(zai)放下(xia)重物時(shi)(shi)，速(su)度(du)不要(yao)太快，液壓(ya)支柱多少錢，以(yi)防(fang)重物突然下(xia)落(luo)而損壞。吊長、大型重物時(shi)(shi)應有專人拉溜繩，防(fang)止因重物擺(bai)動(dong)，造成事故(gu)。

九、起重機工作(zuo)(zuo)時，與起重作(zuo)(zuo)業無關人員嚴禁(jin)在(zai)起重機上逗留(liu)。
