各種起重(zhong)(zhong)設(she)(she)備(bei)的(de)用途不同，構造上有很大差異，但都具(ju)有實現升(sheng)(sheng)降這一基本(ben)動(dong)作的(de)起升(sheng)(sheng)機構。起重(zhong)(zhong)設(she)(she)備(bei)通(tong)常結構龐(pang)大，機構復(fu)雜，能(neng)完(wan)成起升(sheng)(sheng)運(yun)(yun)動(dong)、水(shui)平運(yun)(yun)動(dong)。例如，橋式(shi)(shi)起重(zhong)(zhong)機能(neng)完(wan)成起升(sheng)(sheng)、大車(che)運(yun)(yun)行和小車(che)運(yun)(yun)行3個運(yun)(yun)動(dong)。起重(zhong)(zhong)機械(xie)亦可稱為起重(zhong)(zhong)設(she)(she)備(bei)，是工(gong)業、交(jiao)通(tong)、建筑企業中實現生產(chan)過程機械(xie)化(hua)(hua)、自(zi)動(dong)化(hua)(hua)，起重(zhong)(zhong)設(she)(she)備(bei)租賃資質(zhi)，減輕(qing)繁重(zhong)(zhong)體力勞動(dong)，提高勞動(dong)生產(chan)率(lv)的(de)重(zhong)(zhong)要工(gong)具(ju)和設(she)(she)備(bei)，在我國已(yi)擁有大量的(de)各式(shi)(shi)各樣的(de)起重(zhong)(zhong)設(she)(she)備(bei)。

有些輕小型起(qi)重(zhong)設備的(de)(de)起(qi)重(zhong)能力(li)很大，如(ru)液壓千斤(jin)頂的(de)(de)起(qi)重(zhong)量已達(da) 750噸。升(sheng)降(jiang)(jiang)機(ji)主要作(zuo)垂直或近于垂直的(de)(de)升(sheng)降(jiang)(jiang)運動，具(ju)有固定(ding)的(de)(de)升(sheng)降(jiang)(jiang)路(lu)線，蘇州起(qi)重(zhong)設備，包括電梯、升(sheng)降(jiang)(jiang)臺(tai)、礦井(jing)提升(sheng)機(ji)和(he)料斗升(sheng)降(jiang)(jiang)機(ji)等。起(qi)重(zhong)設備趨向是(shi)增進自動化(hua)程度，提高工作(zuo)效率和(he)使用性能，起(qi)重(zhong)設備維護資質，使操作(zuo)更(geng)簡化(hua)、省力(li)和(he)更(geng)。起(qi)重(zhong)業(ye)中常常需要多(duo)人配(pei)合，共同進行。一個操作(zuo)，要求指揮、捆扎(zha)、駕駛等作(zuo)業(ye)人員配(pei)合熟(shu)練、動作(zuo)協調、互相照應。作(zuo)業(ye)人員應有處(chu)理(li)現場緊急情(qing)況的(de)(de)能力(li)。

起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)械亦可稱為起(qi)重(zhong)(zhong)(zhong)設備，是工(gong)(gong)業、交通、建筑企業中實現(xian)生(sheng)產(chan)過(guo)程機(ji)(ji)械化、自(zi)動化，減輕繁重(zhong)(zhong)(zhong)體力勞(lao)動，起(qi)重(zhong)(zhong)(zhong)設備安裝公司資質，提高(gao)勞(lao)動生(sheng)產(chan)率的重(zhong)(zhong)(zhong)要工(gong)(gong)具(ju)和設備，在我國已擁有大量的各(ge)式各(ge)樣的起(qi)重(zhong)(zhong)(zhong)設備。在高(gao)校實驗室使用(yong)起(qi)重(zhong)(zhong)(zhong)設備雖數量不(bu)多、起(qi)重(zhong)(zhong)(zhong)噸位不(bu)大，但由于起(qi)重(zhong)(zhong)(zhong)設備使用(yong)頻率不(bu)高(gao)，對其維護保養及(ji)安全運行顯(xian)得(de)更為重(zhong)(zhong)(zhong)要。臂架式類型起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)包括汽車(che)起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)、輪(lun)胎(tai)式起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)、履帶式起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)、塔(ta)式起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)、門(men)座式起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)、浮式起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)和鐵(tie)路起(qi)重(zhong)(zhong)(zhong)機(ji)(ji)。
