電(dian)動(dong)葫(hu)蘆(lu)是一(yi)種特起重(zhong)(zhong)設備(bei)，安裝在天(tian)車、龍門吊之上(shang)，電(dian)動(dong)葫(hu)蘆(lu)具有體積小，自重(zhong)(zhong)輕，操作簡單，使用(yong)方(fang)便等特點，用(yong)于工礦(kuang)企業，倉儲，碼(ma)頭等場所。

電(dian)動(dong)(dong)葫蘆結構緊湊，電(dian)機軸線(xian)垂(chui)直(zhi)于卷筒軸線(xian)的電(dian)動(dong)(dong)葫蘆采用蝸輪(lun)傳(chuan)動(dong)(dong)裝置。其缺(que)點為：長度(du)尺寸(cun)(cun)大(da)，寬度(du)方面尺寸(cun)(cun)大(da)，結構粗笨，機械效率低(di)，加(jia)工較難等(deng)。液壓系(xi)(xi)統(tong)為雙重(zhong)控(kong)制，溢流調節閥(fa)、磁接點壓力表均可對壓力進(jin)行控(kong)制。電(dian)器控(kong)制部門(men)采用了(le)低(di)電(dian)壓控(kong)制，增加(jia)了(le)支配系(xi)(xi)統(tong)的安全性(xing)。

電(dian)動(dong)(dong)葫蘆(lu)(lu)主要分為：環鏈電(dian)動(dong)(dong)葫蘆(lu)(lu)、鋼絲繩電(dian)動(dong)(dong)葫蘆(lu)(lu)（防(fang)爆(bao)葫蘆(lu)(lu)）、防(fang)腐電(dian)動(dong)(dong)葫蘆(lu)(lu)、雙卷(juan)筒電(dian)動(dong)(dong)葫蘆(lu)(lu)、卷(juan)揚機、微(wei)型電(dian)動(dong)(dong)葫蘆(lu)(lu)、群(qun)吊電(dian)動(dong)(dong)葫蘆(lu)(lu)、多功能提(ti)升(sheng)機。
