低凈空版的運行式環鏈電動葫蘆自出(chu)廠前就已經安裝好(hao)了運(yun)行(xing)小車系統，無需再為之單獨搭配安裝電動(dong)(dong)小車，而其他(ta)款式(shi)的環(huan)鏈電動(dong)(dong)葫(hu)蘆基本都是上吊(diao)鉤懸掛形式(shi)，需要同(tong)時搭配上電動(dong)(dong)單軌小車才能沿著工字鋼軌道線(xian)路做出(chu)直線(xian)或者(zhe)曲線(xian)、環(huan)繞線(xian)路的重物運(yun)輸操作。

運行(xing)(xing)式環鏈電(dian)(dian)動(dong)葫蘆和電(dian)(dian)動(dong)單(dan)(dan)軌小車(che)(che)安裝完成并懸(xuan)掛在工字鋼(gang)軌道、龍門吊等支撐設備上后，操(cao)作人員可以依靠電(dian)(dian)動(dong)單(dan)(dan)軌小車(che)(che)的遙(yao)控(kong)(kong)器操(cao)控(kong)(kong)電(dian)(dian)動(dong)葫蘆的運行(xing)(xing)線路和運行(xing)(xing)時間(jian)，在整(zheng)個運行(xing)(xing)過程中(zhong)，不僅僅只(zhi)有電(dian)(dian)動(dong)葫蘆承擔著重(zhong)物吊重(zhong)重(zhong)任，電(dian)(dian)動(dong)單(dan)(dan)軌小車(che)(che)同(tong)樣也在承受重(zhong)物的重(zhong)量。

雖然在電源供應充足，電動葫蘆和電動單軌小車承載能力強，均沒有超載使用的前提下，運行式環鏈電動葫蘆可以連續工作20分鐘(zhong)，但是一(yi)旦超過20分鐘(zhong)，就要(yao)暫(zan)停吊重和運行作業，讓電機休息和散(san)熱。
