電(dian)梯(ti)門(men)(men)是電(dian)梯(ti)中非常(chang)重要的一部(bu)分，有兩(liang)個門(men)(men)，從(cong)電(dian)梯(ti)外能看到的、固定(ding)(ding)(ding)在每(mei)層的叫做(zuo)廳門(men)(men)，里面看到的、固定(ding)(ding)(ding)在轎廂隨著轎廂運動的叫做(zuo)轎門(men)(men)。電(dian)梯(ti)門(men)(men)開(kai)(kai)關(guan)一般是由轎門(men)(men)帶(dai)動廳門(men)(men)開(kai)(kai)關(guan)。它的穩定(ding)(ding)(ding)性(xing)、合理(li)性(xing)、安全性(xing)是決定(ding)(ding)(ding)電(dian)梯(ti)等級關(guan)鍵因素(su)。
