升降機在建筑行業的應用越來越廣泛，升降機在使用過程中,電氣具有重要的影響，在使用之前升降機廠家需要對機器進行一定的檢查。
1、需要用接地電阻測試儀測量升降機鋼結構及電器設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兆歐表測電動機及電器元件的對地電阻應不小于1MΩ;
Lift manufacturers need to use 500V megger test motor and electrical components to ground resistance shall be not less than 1MΩ;
3、需要檢查升降機各安裝控制開關,分別打開吊籠籠上各個門,觸動斷繩保護開關,上下限位開關、極限開關等均應能夠起作用;
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、需要校核電動機界限,吊籠上、下運動方向應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.
