Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a transportation carriage which travels with the power, can travel even in a section where power supply cannot be received from a main power source device, and also can hold the power necessary for travel resumption even if the traveling is stopped in a section where the power supply cannot be received.SOLUTION: In a case where a drive device 22 cannot receive the power supply from a power reception device 24 being a main power source device, the drive device 22 is driven with the power stored in a power storage device 26. A voltage converter 30 performing voltage conversion among the drive device 22, the power reception device 24 and the power storage device 26 monitors the storage voltage Voutput from the power storage device 26. In a case where the storage voltage Vbecomes lower than the predetermined lower limit voltage while the voltage converter 30 is operating as a booster, the voltage converter 30 as the booster is disconnected from the power storage device 26.SELECTED DRAWING: Figure 2 【課題】電力で走行する搬送台車において、主電源装置からの電力供給が受けられない区間においても走行可能で、かつ電力供給が受けられない区間で走行停止しても走行再開のために必要な電力を保持しておくことが可能な搬送台車を提供する。【解決手段】駆動装置２２が主電源装置である受電装置２４からの電力供給を受けられない場合には、蓄電装置２６に蓄積された電力によって駆動装置２２が駆動される。駆動装置２２、受電装置２４、蓄電装置２６の間で電圧変換を行う電圧変換器３０が、蓄電装置２６から出力される蓄積電圧ＶＢを監視し、電圧変換器３０が昇圧器として動作している間に蓄積電圧ＶＢが予め定められた下限電圧より低くなった場合には、昇圧器としての電圧変換器３０と蓄電装置２６との接続が遮断される。【選択図】図２
