PROBLEM TO BE SOLVED: To provide a liquid conveying vehicle that can suppress power consumption.SOLUTION: When a switch SW2 of a liquid quantity display instrument is turned ON, a regularly opened contact point SW2a is closed so that currents are flown to a relay RY2. When currents are flown to the relay RY2, the regularly opened contact point RY2a2 is closed so that currents are flown to relays RY4 and RY5 and the like. When currents are flown to the relay RY4, the regularly opened contact point RY4b is opened so that supply of power from a battery DC1 to a PLC71 is shut off. While, by the flowing of the currents to the relay RY5, regularly opened contact points RY5a1 and RY5a2 are closed so that currents are flown to a relay RY6. When currents are flown to the relay RY6, a regularly opened contact point RY6a is closed so that power is supplied to the liquid quantity display instrument 4. This allows the liquid quantity display instrument 4 to be turned on by operation for switching ON the switch SW2 of the liquid quantity display instrument without turning on the PLC71.SELECTED DRAWING: Figure 3
【課題】電力消費を抑制し得る液体運搬車両を提供すること。【解決手段】液量表示器スイッチSW2を「入」とすると常開接点SW2aが閉じられ、リレーRY2に電流が流れる。リレーRY2に電流が流れると常開接点RY2a2が閉じられ、リレーRY4、RY5等に電流が流れる。リレーRY4に電流が流れると常閉接点RY4bが開かれ、バッテリDC1からPLC71への電力供給が遮断される。一方、リレーRY5に電流が流れることによって常開接点RY5a1,RY5a2が閉じられ、リレーRY6に電流が流れる。リレーRY6に電流が流れると常開接点RY6aが閉じられ、液量表示器4に電力が供給される。よって、液量表示器スイッチSW2を「入」に切り換える操作により、PLC71をオンにすることなく、液量表示器4をオンにすることができる。【選択図】図3
