1、檢查(cha)電(dian)(dian)動平車液壓(ya)電(dian)(dian)機(ji)(ji)(ji)是否(fou)有(you)電(dian)(dian)壓(ya)，電(dian)(dian)機(ji)(ji)(ji)是否(fou)短路(lu)或(huo)開路(lu)泄漏，碳(tan)(tan)刷是否(fou)嚴(yan)重磨損(sun)。修(xiu)(xiu)理方(fang)法:修(xiu)(xiu)理電(dian)(dian)路(lu)，更換電(dian)(dian)機(ji)(ji)(ji)碳(tan)(tan)刷，修(xiu)(xiu)理電(dian)(dian)機(ji)(ji)(ji)銅頭，修(xiu)(xiu)理液壓(ya)電(dian)(dian)機(ji)(ji)(ji)總(zong)成或(huo)更換新的液壓(ya)電(dian)(dian)機(ji)(ji)(ji)。

　　2、檢查電動平(ping)車(che)提(ti)升接觸(chu)器總成是(shi)否(fou)燒壞，線圈是(shi)否(fou)短路或(huo)斷開。修(xiu)理方法:修(xiu)理接觸(chu)器的鉑觸(chu)點或(huo)直接更換液壓(ya)接觸(chu)器總成。

　　3、檢查電(dian)動平車升降開關(guan)和(he)(he)升降附件電(dian)路是(shi)否松動或(huo)短路，微動開關(guan)是(shi)否損壞。修理(li)方法:修理(li)和(he)(he)清潔電(dian)路，更換或(huo)修理(li)微動開關(guan)。

　　4、首(shou)先，檢查(cha)電(dian)(dian)動平車的(de)主動電(dian)(dian)池(chi)是否有電(dian)(dian)壓(ya)。如果(guo)有電(dian)(dian)壓(ya)，檢查(cha)電(dian)(dian)壓(ya)是否能正常(chang)使用(yong)。修理方(fang)法:如果(guo)電(dian)(dian)池(chi)沒(mei)有電(dian)(dian)壓(ya)或(huo)電(dian)(dian)壓(ya)過低(di)，直接給電(dian)(dian)池(chi)充電(dian)(dian)。

　　5、檢(jian)查電動平(ping)車起重模(mo)塊是否燒(shao)壞，短路或斷(duan)開。修理方法：修理或更(geng)換模(mo)塊組件(jian)。
