電(dian)(dian)動(dong)扶(fu)梯(ti)(Escalator)，亦(yi)稱(cheng)自(zi)動(dong)扶(fu)梯(ti)，或自(zi)動(dong)行(xing)人電(dian)(dian)梯(ti)、扶(fu)手(shou)電(dian)(dian)梯(ti)、電(dian)(dian)扶(fu)梯(ti)，是(shi)帶有(you)循(xun)環運(yun)行(xing)階梯(ti)的(de)一類扶(fu)梯(ti)，是(shi)用(yong)于向上或向下傾斜運(yun)送(song)乘客的(de)固定電(dian)(dian)力驅動(dong)設備(bei)。

電(dian)(dian)動(dong)(dong)枎梯(ti)一般是斜(xie)置。行(xing)(xing)(xing)(xing)人在(zai)扶(fu)(fu)(fu)梯(ti)的(de)一端站上自動(dong)(dong)行(xing)(xing)(xing)(xing)走(zou)的(de)梯(ti)級，便會(hui)自動(dong)(dong)被帶到扶(fu)(fu)(fu)梯(ti)的(de)另(ling)一端，途中梯(ti)級會(hui)一路保持水平(ping)。枎梯(ti)在(zai)兩(liang)旁設有跟梯(ti)級同步移動(dong)(dong)的(de)扶(fu)(fu)(fu)手，供使(shi)用者扶(fu)(fu)(fu)握(wo)。電(dian)(dian)動(dong)(dong)扶(fu)(fu)(fu)梯(ti)可(ke)以是永遠向一個方向行(xing)(xing)(xing)(xing)走(zou)，但多(duo)數都可(ke)以根據(ju)時間、人流等需要(yao)，由管理人員控(kong)制行(xing)(xing)(xing)(xing)走(zou)方向。另(ling)一種和電(dian)(dian)動(dong)(dong)扶(fu)(fu)(fu)梯(ti)十分類似的(de)行(xing)(xing)(xing)(xing)人運\輸(shu)工(gong)具，是自動(dong)(dong)人行(xing)(xing)(xing)(xing)道(Automatic Sidewalk)。兩(liang)者的(de)分別(bie)主要(yao)是自動(dong)(dong)行(xing)(xing)(xing)(xing)人道是沒有梯(ti)級的(de)；多(duo)數只會(hui)在(zai)平(ping)地上行(xing)(xing)(xing)(xing)走(zou)，或是稍微傾(qing)斜(xie)。
