電(dian)動(dong)扶梯(ti)(Escalator),亦稱(cheng)自動(dong)扶梯(ti),或自動(dong)行(xing)人電(dian)梯(ti)、扶手電(dian)梯(ti)、電(dian)扶梯(ti),是帶(dai)有循(xun)環運(yun)(yun)行(xing)階(jie)梯(ti)的一類扶梯(ti),是用于向上或向下傾(qing)斜運(yun)(yun)送乘客的固定(ding)電(dian)力(li)驅動(dong)設備。
電(dian)(dian)動(dong)(dong)(dong)枎(fu)梯(ti)(ti)一(yi)般是(shi)斜(xie)置。行(xing)(xing)人(ren)(ren)在(zai)扶(fu)(fu)梯(ti)(ti)的(de)(de)(de)一(yi)端站上(shang)(shang)自(zi)動(dong)(dong)(dong)行(xing)(xing)走的(de)(de)(de)梯(ti)(ti)級(ji),便會(hui)自(zi)動(dong)(dong)(dong)被帶到扶(fu)(fu)梯(ti)(ti)的(de)(de)(de)另一(yi)端,途(tu)中梯(ti)(ti)級(ji)會(hui)一(yi)路保(bao)持水(shui)平。枎(fu)梯(ti)(ti)在(zai)兩旁設有跟(gen)梯(ti)(ti)級(ji)同步(bu)移動(dong)(dong)(dong)的(de)(de)(de)扶(fu)(fu)手,供(gong)使用者扶(fu)(fu)握。電(dian)(dian)動(dong)(dong)(dong)扶(fu)(fu)梯(ti)(ti)可(ke)以是(shi)永遠(yuan)向(xiang)(xiang)(xiang)一(yi)個方(fang)向(xiang)(xiang)(xiang)行(xing)(xing)走,但多數都可(ke)以根(gen)據(ju)時間、人(ren)(ren)流(liu)等(deng)需要,由管理人(ren)(ren)員控制行(xing)(xing)走方(fang)向(xiang)(xiang)(xiang)。另一(yi)種和電(dian)(dian)動(dong)(dong)(dong)扶(fu)(fu)梯(ti)(ti)十分類似的(de)(de)(de)行(xing)(xing)人(ren)(ren)運(yun)\輸(shu)工具,是(shi)自(zi)動(dong)(dong)(dong)人(ren)(ren)行(xing)(xing)道(dao)(Automatic Sidewalk)。兩者的(de)(de)(de)分別主要是(shi)自(zi)動(dong)(dong)(dong)行(xing)(xing)人(ren)(ren)道(dao)是(shi)沒有梯(ti)(ti)級(ji)的(de)(de)(de);多數只(zhi)會(hui)在(zai)平地上(shang)(shang)行(xing)(xing)走,或是(shi)稍微傾斜(xie)。
