碼頭吊(diao)起(qi)重機(ji)(ji)(ji)組(zu)成動(dong)(dong)(dong)力裝置由(you)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)、減(jian)速器(qi)(qi)、離合(he)器(qi)(qi)、制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)、繩(sheng)筒及鋼絲繩(sheng)等組(zu)成。電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)為(wei)傍磁(ci)式單相電(dian)(dian)容(rong)電(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)，規劃(hua)有斷電(dian)(dian)即(ji)制(zhi)(zhi)動(dong)(dong)(dong)的機(ji)(ji)(ji)構；電(dian)(dian)機(ji)(ji)(ji)還(huan)裝有熱敏開關，可(ke)防(fang)止電(dian)(dian)機(ji)(ji)(ji)過熱而燒(shao)毀；減(jian)速機(ji)(ji)(ji)為(wei)兩(liang)級齒輪減(jian)速，固連于電(dian)(dian)機(ji)(ji)(ji)；離合(he)器(qi)(qi)、制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)與蠅筒裝為(wei)一體，但離合(he)器(qi)(qi)處于脫離狀態時，可(ke)實(shi)現快速下(xia)降，操作制(zhi)(zhi)動(dong)(dong)(dong)器(qi)(qi)可(ke)操控下(xia)降速度以避免發生沖(chong)擊。
碼(ma)頭(tou)吊起重機(ji)動力裝置外殼正面所開的圓孔可用來安裝吹風機，用戶可根據需求裝備吹風機進行強制冷卻。 支架部分由螺桿，千斤螺母及立桿構成的主桿和滾動臂組成。滾動臂可在主桿上滾動360度，在臂端設有行程開關以防操作失誤或按鈕失靈而形成的起吊過位事故。操作按鈕起動器實現電機正反轉可將鋼絲繩卷繞、放開，并經過支架部分滑輪起吊，下放物件來完結吊運作業。
