電(dian)(dian)動扶梯(ti)(ti)(ti)(ti)(Escalator)，亦稱自(zi)動扶梯(ti)(ti)(ti)(ti)，或自(zi)動行人電(dian)(dian)梯(ti)(ti)(ti)(ti)、扶手電(dian)(dian)梯(ti)(ti)(ti)(ti)、電(dian)(dian)扶梯(ti)(ti)(ti)(ti)，是(shi)帶(dai)有(you)循(xun)環運行階梯(ti)(ti)(ti)(ti)的(de)一類扶梯(ti)(ti)(ti)(ti)，是(shi)用于(yu)向上(shang)或向下傾斜運送(song)乘客的(de)固定電(dian)(dian)力驅(qu)動設備。

電(dian)動(dong)(dong)(dong)枎梯(ti)一(yi)(yi)般是(shi)(shi)斜(xie)置(zhi)。行(xing)(xing)人在扶(fu)(fu)(fu)梯(ti)的(de)一(yi)(yi)端站上(shang)自(zi)動(dong)(dong)(dong)行(xing)(xing)走(zou)(zou)的(de)梯(ti)級(ji)，便會(hui)自(zi)動(dong)(dong)(dong)被帶(dai)到(dao)扶(fu)(fu)(fu)梯(ti)的(de)另一(yi)(yi)端，途中梯(ti)級(ji)會(hui)一(yi)(yi)路保持水平。枎梯(ti)在兩(liang)(liang)旁設有跟梯(ti)級(ji)同步(bu)移動(dong)(dong)(dong)的(de)扶(fu)(fu)(fu)手(shou)，供(gong)使用者(zhe)扶(fu)(fu)(fu)握。電(dian)動(dong)(dong)(dong)扶(fu)(fu)(fu)梯(ti)可以是(shi)(shi)永(yong)遠向(xiang)(xiang)一(yi)(yi)個方向(xiang)(xiang)行(xing)(xing)走(zou)(zou)，但多數都可以根據時間(jian)、人流等需要，由管理人員控(kong)制行(xing)(xing)走(zou)(zou)方向(xiang)(xiang)。另一(yi)(yi)種和電(dian)動(dong)(dong)(dong)扶(fu)(fu)(fu)梯(ti)十分類似的(de)行(xing)(xing)人運\輸(shu)工具，是(shi)(shi)自(zi)動(dong)(dong)(dong)人行(xing)(xing)道(dao)(Automatic Sidewalk)。兩(liang)(liang)者(zhe)的(de)分別主要是(shi)(shi)自(zi)動(dong)(dong)(dong)行(xing)(xing)人道(dao)是(shi)(shi)沒有梯(ti)級(ji)的(de)；多數只會(hui)在平地上(shang)行(xing)(xing)走(zou)(zou)，或是(shi)(shi)稍微傾斜(xie)。
