본 발명은 전력으로 주행함으로써 물품을 반송하는 반송대차에 관한 것이다. 주행을 위한 구동 장치(22)가 주전원 장치인 수전 장치(24)로부터의 전력 공급을 받지 않는 경우에는 축전 장치(26)에 축적된 전력에 의해 구동 장치(22)가 구동된다. 구동 장치(22), 수전 장치(24), 축전 장치(26) 사이에서 전압 변환을 행하는 전압 변환기(30)가 축전 장치(26)로부터 출력되는 축적 전압(VB)을 감시하고, 전압 변환기(30)가 승압기로서 동작하고 있는 사이에 축적 전압(VB)이 미리 정해진 하한 전압보다 낮아진 경우에는 승압기로서의 전압 변환기(30)와 축전 장치(26)의 접속이 차단된다.

    The invention relates to conveyance carrier, which is driven by electric power to deliver cargoes. Under the situation that a driving device (22) for travelling does not receive electric power from anelectricity receiving device (24) taken as a main power supply, the driving device (22) utilizes electric power stored in an electricity storage device (26) to carry out driving. A voltage converter(30), which carries out voltage conversion among the driving device (22), the electricity receiving device (24), and the electricity storage device (26), is used to monitor the accumulation voltage (VB) output by the electricity storage device (26). During the period when the voltage converter (30) is taken as a voltage booster to carry out operations, when the accumulation voltage (VB) is lower than a predetermined lower limit of voltage, the connection between the voltage converter (30) taken as a voltage booster and the electricity storage device (26) is cut off.
