軌道電動平車(che)(che)是電動有軌運(yun)(yun)輸車(che)(che)輛，又稱(cheng)過(guo)平車(che)(che)、臺車(che)(che)、電動平車(che)(che)，具有結(jie)構簡單、使(shi)用方便(bian)、維(wei)護方便(bian)、承載能力大、污(wu)染少等優點，有效解決廠內跨度(du)間的產(chan)品運(yun)(yun)輸問題，作(zuo)為(wei)車(che)(che)間內配(pei)合起重(zhong)機運(yun)(yun)輸重(zhong)物(wu)過(guo)跨，廣泛應用于機械(xie)制造(zao)和冶金廠。

　　1、卷筒供電平車

　　電(dian)(dian)(dian)(dian)纜卷(juan)筒(tong)交(jiao)流380V供(gong)電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)纜卷(juan)筒(tong)為磁滯耦(ou)合式，確(que)保電(dian)(dian)(dian)(dian)纜受(shou)力均勻，不易(yi)拉壞。380交(jiao)流V在平(ping)車(che)上(shang)YZ起重冶(ye)金(jin)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)長度(du)的影響，起重冶(ye)金(jin)用電(dian)(dian)(dian)(dian)機(ji)供(gong)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)機(ji)拖平(ping)車(che)運(yun)行，平(ping)車(che)運(yun)行時電(dian)(dian)(dian)(dian)纜卷(juan)筒(tong)自動(dong)卷(juan)起或(huo)放出，一般較大運(yun)行距(ju)離不足2萬(wan)m。

　　2、拖纜供電式平車

　　牽引(yin)(yin)鋼絲繩通過電(dian)(dian)纜(lan)滑車引(yin)(yin)入控(kong)制箱，然后將(jiang)電(dian)(dian)纜(lan)的一端連接到地面電(dian)(dian)源上，YZ電(dian)(dian)機提(ti)供電(dian)(dian)力，以拖動平車運行。但運行距離不能太長(chang)，一般(ban)不能超過50。m，太長(chang)容(rong)易纏繞電(dian)(dian)纜(lan)。

　　由于起動(dong)時(shi)流(liu)經軌道的起動(dong)電(dian)(dian)流(liu)非常大（達萬）A），此時(shi)，軌道末端有很大的電(dian)(dian)壓(ya)(ya)降，導致(zhi)單相(xiang)電(dian)(dian)容電(dian)(dian)機難以啟動(dong)，因此單相(xiang)電(dian)(dian)壓(ya)(ya)降KPD平車較大載重(zhong)噸位(wei)50噸以上V低壓(ya)(ya)軌道供(gong)電(dian)(dian)采用三相(xiang)36，YZ起重(zhong)冶金用電(dian)(dian)機。

　　3、蓄電池平車

　　用(yong)蓄電池供電。蓄電池供電直流牽引電機，直流電機拖平車運行(xing)。運行(xing)距(ju)離不受限制(zhi)。安全性能更大，機動(dong)靈活(huo)，運行(xing)距(ju)離不受限制(zhi)，對軌道無絕緣要求(qiu)，施工方便成(cheng)本低。

　　平(ping)車(che)可以加裝工業(ye)無線遙控裝置(zhi)。
