The present invention relates to a conveyance carrier for conveying goods while traveling by electric power. A driving device (22) is operated by electric power accumulated in an electric condenser (26) if the driving device (22) does not receive electric power from a power receiving device (24), which is a main power supply. A voltage converter (30) for converting voltage among the driving device (22), the power receiving device (24) and the electric condenser (26) monitors accumulated voltage (VB) outputted from the electric condenser (26), and connection between the voltage converter (30) as a booster and the electric condenser (26) is blocked if the accumulated voltage (VB) gets lower than a predetermined lowest voltage while the voltage converter (30) acts as the booster.

    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(V)을 감시하고, 전압 변환기(30)가 승압기로서 동작하고 있는 사이에 축적 전압(V)이 미리 정해진 하한 전압보다 낮아진 경우에는 승압기로서의 전압 변환기(30)와 축전 장치(26)의 접속이 차단된다.
