電動平板車在使用時會突然出現不能行駛的情況，那么此時該檢測什么呢？

　　檢查(cha)升(sheng)降接(jie)(jie)觸(chu)(chu)器(qi)總(zong)成是否(fou)燒壞，線圈是否(fou)短路或(huo)斷(duan)開(kai)，維(wei)(wei)修方(fang)法：維(wei)(wei)修接(jie)(jie)觸(chu)(chu)器(qi)鉑接(jie)(jie)觸(chu)(chu)點(dian)或(huo)直(zhi)接(jie)(jie)更換液壓接(jie)(jie)觸(chu)(chu)器(qi)總(zong)成。

　　檢查升(sheng)降(jiang)(jiang)開(kai)關和升(sheng)降(jiang)(jiang)附件(jian)電路是(shi)否(fou)松動或短(duan)路，微(wei)動開(kai)關是(shi)否(fou)損(sun)壞。維(wei)修(xiu)方法：維(wei)修(xiu)和清潔(jie)電路，更(geng)換(huan)或維(wei)修(xiu)微(wei)動開(kai)關。

　　檢查液壓(ya)電(dian)(dian)(dian)機是否有電(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)機是否短路或開路泄漏，碳刷(shua)是否磨損(sun)嚴(yan)重。維修(xiu)(xiu)方法：維修(xiu)(xiu)電(dian)(dian)(dian)路，更換電(dian)(dian)(dian)機碳刷(shua)，維修(xiu)(xiu)電(dian)(dian)(dian)機銅頭，維修(xiu)(xiu)液壓(ya)電(dian)(dian)(dian)機組件或更換新液壓(ya)電(dian)(dian)(dian)機。

　　檢查起重模(mo)塊是(shi)否燒壞、短路(lu)或斷開。修理方法(fa)：修理或更換模(mo)塊組件(jian)。

　　檢查(cha)主(zhu)動電(dian)(dian)(dian)(dian)池是否有電(dian)(dian)(dian)(dian)壓，如果(guo)有電(dian)(dian)(dian)(dian)壓，檢查(cha)電(dian)(dian)(dian)(dian)壓是否能(neng)正常(chang)使用，維修方法：如果(guo)電(dian)(dian)(dian)(dian)池沒有電(dian)(dian)(dian)(dian)壓或電(dian)(dian)(dian)(dian)壓太(tai)低，直(zhi)接(jie)給電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)。

　　電(dian)壓(ya)(ya)過(guo)低：電(dian)機(ji)端(duan)電(dian)壓(ya)(ya)比額定電(dian)壓(ya)(ya)低10%以上，電(dian)機(ji)啟動(dong)(dong)轉矩過(guo)小，使電(dian)動(dong)(dong)平(ping)車無法移(yi)動(dong)(dong)和工作。檢(jian)查時(shi)，用(yong)萬用(yong)表或電(dian)壓(ya)(ya)表測(ce)量電(dian)機(ji)輸入端(duan)電(dian)壓(ya)(ya)。

　　缺相：驅(qu)(qu)動電(dian)(dian)(dian)機(ji)主(zhu)、控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路電(dian)(dian)(dian)器(qi)損壞、線路斷(duan)開或(huo)接觸不(bu)良，也會使平(ping)車(che)驅(qu)(qu)動電(dian)(dian)(dian)機(ji)缺相不(bu)能正常工作。在這種情況(kuang)下，需要對主(zhu)、控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路進行(xing)維護。維修時(shi)，為(wei)防止主(zhu)、控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路給三(san)相電(dian)(dian)(dian)機(ji)的(de)電(dian)(dian)(dian)源缺相，燒毀電(dian)(dian)(dian)機(ji)，或(huo)驅(qu)(qu)動電(dian)(dian)(dian)機(ji)突然(ran)通電(dian)(dian)(dian)，造成危(wei)害。首先(xian)，將電(dian)(dian)(dian)機(ji)從(cong)電(dian)(dian)(dian)源線上斷(duan)開，只給主(zhu)、控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路送電(dian)(dian)(dian)，然(ran)后點擊啟動和停止開關(guan)，檢查分析控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)器(qi)和電(dian)(dian)(dian)路的(de)工作情況(kuang)，修理或(huo)更(geng)換有問題的(de)電(dian)(dian)(dian)器(qi)或(huo)電(dian)(dian)(dian)路。當確認主(zhu)、控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路無故障(zhang)時(shi)，可(ke)重新試運行(xing)。
