To solve a problem that when a vehicle is driven by driving of one of a first engine and a second engine, a component of a transmission which is connected to the engine in the stop state is worn by corotation of a travel device.SOLUTION: A transportation vehicle of the invention includes: a vehicle body including a load-carrying platform, a first travel device, and a second travel device; a first engine for driving the first travel device; a second engine for driving the second travel device; a first power transmission device which transmits power of the first engine to the first travel device; and a second power transmission device which transmits power of the second engine to the second travel device. In a first engine driving state where the first engine is driven and the second engine is not driven, the first power transmission device and the second power transmission device are controlled in a manner that the first power transmission device can transmit the power and the second power transmission device is inhibited from transmitting the power. In a second engine driving state where the second engine is driven and the first engine is not driven, the first power transmission device and the second power transmission device are controlled in a manner that the second power transmission device can transmit the power and the first power transmission device is inhibited from transmitting the power.SELECTED DRAWING: Figure 1

    【課題】第1エンジン及び第2エンジンの一方だけの駆動により走行したとき、停止側のエンジンに接続されたトランスミッションの部品が走行装置の連れ回りにより摩耗等する。【解決手段】本発明の搬送車は、荷台と、第1走行装置及び第2走行装置とを含む車体と、第1走行装置を駆動するための第1エンジンと、第2走行装置を駆動するための第2エンジンと、第1エンジンの動力を第1走行装置に伝達する第1動力伝達装置と、第2エンジンの動力を第2走行装置に伝達する第2動力伝達装置とを備え、第1エンジンが駆動され且つ第2エンジンが駆動されない第1エンジン駆動状態において、第1動力伝達装置が動力を伝達可能であって且つ第2伝達装置が動力を伝達しないように制御され、第2エンジンが駆動され且つ第1エンジンが駆動されない第2エンジン駆動状態において、第2動力伝達装置が動力を伝達可能であって且つ第1伝達装置が動力を伝達しないように制御される。【選択図】図1
