1、上、下限位器：為防止吊籠上、下時超過需停位置，或因司機誤操作以及電氣故障等原因繼續上行，或下降引發事故而設置的裝置。鋁合金軌道廠家介紹安裝(zhuang)在(zai)(zai)吊(diao)籠和導軌架(jia)上，限(xian)位(wei)裝(zhuang)置(zhi)由限(xian)位(wei)碰塊和限(xian)位(wei)開關(guan)構成，設在(zai)(zai)吊(diao)籠頂(ding)部的(de)限(xian)位(wei)裝(zhuang)置(zhi)，可防止冒頂(ding)；設在(zai)(zai)吊(diao)籠底部的(de)限(xian)位(wei)裝(zhuang)置(zhi)，可準確停層，屬于自動復位(wei)型。

2、安(an)全鉤：為防(fang)止(zhi)吊籠(long)達到(dao)預(yu)先設(she)定位(wei)置(zhi)，上限位(wei)器和上極(ji)限限位(wei)器因各種原(yuan)因不(bu)能及時動作，吊籠(long)繼續向上運行(xing)，將導(dao)致吊籠(long)沖擊導(dao)軌架頂(ding)部面發生傾翻墜落事(shi)(shi)故(gu)而設(she)置(zhi)的鉤塊狀(zhuang)，也是***一道(dao)安(an)全裝置(zhi)。它能使吊籠(long)上行(xing)到(dao)軌架安(an)全防(fang)護設(she)施頂(ding)部時，安(an)全地(di)溝在(zai)導(dao)軌架上，防(fang)止(zhi)吊籠(long)出(chu)軌，保證(zheng)吊籠(long)不(bu)發生傾覆墜落事(shi)(shi)故(gu)。

3、上(shang)(shang)、下極限(xian)(xian)(xian)(xian)(xian)限(xian)(xian)(xian)(xian)(xian)位(wei)(wei)器：是在(zai)上(shang)(shang)、下限(xian)(xian)(xian)(xian)(xian)位(wei)(wei)器不起作用時，當吊(diao)籠運行超(chao)過限(xian)(xian)(xian)(xian)(xian)位(wei)(wei)開(kai)關和越程后，能及時切斷電(dian)源使吊(diao)籠停車。極限(xian)(xian)(xian)(xian)(xian)限(xian)(xian)(xian)(xian)(xian)位(wei)(wei)是非(fei)自動復位(wei)(wei)型。動作后只能手(shou)動復位(wei)(wei)才能使吊(diao)籠重新啟動。極限(xian)(xian)(xian)(xian)(xian)限(xian)(xian)(xian)(xian)(xian)位(wei)(wei)器安裝(zhuang)在(zai)吊(diao)籠和導軌架上(shang)(shang)。越程是指限(xian)(xian)(xian)(xian)(xian)位(wei)(wei)開(kai)光(guang)與極限(xian)(xian)(xian)(xian)(xian)位(wei)(wei)開(kai)關之間所規(gui)定的(de)安全距離。

4、緩(huan)(huan)沖彈簧(huang)(huang)(huang)：裝在(zai)與基礎(chu)架(jia)(jia)連接的彈簧(huang)(huang)(huang)座上(shang)，以便(bian)當吊(diao)籠發生墜(zhui)落事故時，減輕吊(diao)籠的沖擊，同時保證(zheng)吊(diao)籠和(he)(he)配重下(xia)降著地時成柔性(xing)接觸(chu)，減緩(huan)(huan)吊(diao)籠和(he)(he)配重著地時的沖擊。緩(huan)(huan)沖彈簧(huang)(huang)(huang)有圓(yuan)(yuan)錐卷彈簧(huang)(huang)(huang)和(he)(he)圓(yuan)(yuan)柱(zhu)螺旋(xuan)彈簧(huang)(huang)(huang)兩種(zhong)。通(tong)常每個吊(diao)籠對應的底架(jia)(jia)上(shang)有兩個或(huo)三(san)個圓(yuan)(yuan)錐卷彈簧(huang)(huang)(huang)或(huo)四個圓(yuan)(yuan)柱(zhu)螺旋(xuan)彈簧(huang)(huang)(huang)。
