升降機(jī)在建筑行業(yè)的應(yīng)用越來(lái)越廣泛，升降機(jī)在使用過(guò)程中,電氣具有重要的影響，在使用之前升降機(jī)廠家需要對(duì)機(jī)器進(jìn)行一定的檢查。

1、需要用接地電阻測(cè)試儀測(cè)量升降機(jī)鋼結(jié)構(gòu)及電器設(shè)備金屬外殼的接地電阻，不得大于4Ω;
Lift manufacturers need to measure ground resistance tester ground resistance of steel and electrical equipment lifts the metal shell, no larger than 4Ω;
    
2、需要用500V兆歐表測(cè)電動(dòng)機(jī)及電器元件的對(duì)地電阻應(yīng)不小于1MΩ;
Lift manufacturers need to use 500V megger test motor and electrical components to ground resistance shall be not less than 1MΩ;
3、需要檢查升降機(jī)各安裝控制開(kāi)關(guān),分別打開(kāi)吊籠籠上各個(gè)門(mén),觸動(dòng)斷繩保護(hù)開(kāi)關(guān),上下限位開(kāi)關(guān)、極限開(kāi)關(guān)等均應(yīng)能夠起作用;
Lifts lift manufacturers need to check each installation control switch, respectively, on each cage open cage door, touched off the rope protection switch, upper and lower limit switches, limit switches, etc. should be able to work;
   
4、需要校核電動(dòng)機(jī)界限,吊籠上、下運(yùn)動(dòng)方向應(yīng)與操作盒所示方向一致。
Lift manufacturers need to check the motor boundaries, hanging on the cage, under the direction of movement should be consistent with the operation of the cartridge in the direction shown.
