電(dian)動(dong)扶梯(Escalator),亦稱自(zi)動(dong)扶梯,或自(zi)動(dong)行(xing)人電(dian)梯、扶手電(dian)梯、電(dian)扶梯,是(shi)帶(dai)有循環運行(xing)階梯的(de)一(yi)類(lei)扶梯,是(shi)用(yong)于向(xiang)上(shang)或向(xiang)下傾(qing)斜運送乘客(ke)的(de)固定電(dian)力驅動(dong)設備。
電(dian)動(dong)(dong)(dong)枎(fu)(fu)梯一般是(shi)(shi)斜置。行(xing)人(ren)(ren)在(zai)扶(fu)梯的一端站上(shang)自動(dong)(dong)(dong)行(xing)走(zou)(zou)的梯級,便(bian)會自動(dong)(dong)(dong)被(bei)帶到扶(fu)梯的另一端,途(tu)中梯級會一路(lu)保持水平(ping)。枎(fu)(fu)梯在(zai)兩(liang)旁設有跟梯級同步移動(dong)(dong)(dong)的扶(fu)手,供使用者扶(fu)握。電(dian)動(dong)(dong)(dong)扶(fu)梯可(ke)以是(shi)(shi)永遠向(xiang)(xiang)一個方向(xiang)(xiang)行(xing)走(zou)(zou),但多數都(dou)可(ke)以根據時間、人(ren)(ren)流等(deng)需(xu)要,由管理人(ren)(ren)員控制行(xing)走(zou)(zou)方向(xiang)(xiang)。另一種和電(dian)動(dong)(dong)(dong)扶(fu)梯十分類似的行(xing)人(ren)(ren)運(yun)\輸工具,是(shi)(shi)自動(dong)(dong)(dong)人(ren)(ren)行(xing)道(Automatic Sidewalk)。兩(liang)者的分別主要是(shi)(shi)自動(dong)(dong)(dong)行(xing)人(ren)(ren)道是(shi)(shi)沒(mei)有梯級的;多數只會在(zai)平(ping)地(di)上(shang)行(xing)走(zou)(zou),或是(shi)(shi)稍微(wei)傾(qing)斜。
