懸臂吊屬于工業部件，是屬于輕型工作強度起重機，由立柱，回轉臂回轉驅動裝置及電動葫蘆組成，具有自重輕，跨度大，起重量大，經濟耐用。

懸(xuan)臂(bei)吊起(qi)(qi)重(zhong)(zhong)機(ji)工(gong)作強度為輕型，起(qi)(qi)重(zhong)(zhong)機(ji)由(you)立柱(zhu)(zhu)，回(hui)轉(zhuan)臂(bei)回(hui)轉(zhuan)驅(qu)動(dong)(dong)裝(zhuang)置(zhi)及(ji)電動(dong)(dong)葫蘆組成(cheng)，立柱(zhu)(zhu)下端(duan)通過(guo)地(di)腳螺栓固定在(zai)混凝土基礎上，由(you)擺線針輪(lun)(lun)減速裝(zhuang)置(zhi)來驅(qu)動(dong)(dong)懸(xuan)臂(bei)回(hui)轉(zhuan)，電動(dong)(dong)葫蘆在(zai)懸(xuan)臂(bei)工(gong)字鋼上作左(zuo)右直線運(yun)行(xing)，并起(qi)(qi)吊重(zhong)(zhong)物。起(qi)(qi)重(zhong)(zhong)機(ji)旋(xuan)臂(bei)為空心型鋼結構，自重(zhong)(zhong)輕，跨度大，起(qi)(qi)重(zhong)(zhong)量大，經濟耐用。內置(zhi)式(shi)行(xing)走機(ji)構，采用帶滾動(dong)(dong)軸(zhou)承的特種工(gong)程(cheng)塑(su)料走輪(lun)(lun)，摩(mo)擦力小，行(xing)走輕快(kuai);結構尺寸小，特別有利(li)于提高吊鉤(gou)行(xing)程(cheng)。
