PROBLEM TO BE SOLVED: To provide a tank-equipped wheeled vehicle having a liquid level notifying device that can reliably notify its operator present in the vicinity of the vehicle that the liquid tank is empty or full even if he or she is not looking at the liquid surface level.SOLUTION: A liquid level notifying device of a high-pressure washing vehicle is equipped with a level gauge capable of detecting the maximum liquid level and the minimum liquid level of the liquid surface in a liquid tank, a notifying buzzer 9 and a notifying circuit unit 20 that actuates the notifying buzzer 9 when the liquid surface reaches or surpasses the maximum liquid level and when the surface reaches or falls below the minimum liquid level. The notifying circuit has a buzzer stop switch 11 capable of stopping the notifying buzzer 9 at work. If the notifying buzzer 9 is stopped by operation of the buzzer stop switch after the detection of the liquid level of the liquid tank at or above the maximum, the operation of a maximum liquid level detecting circuit is invalidated, and the operation of a minimum liquid level detecting circuit is switched over to a valid state.SELECTED DRAWING: Figure 5
【課題】例え作業者が液面位置を目視していなかったとしても、車両近傍にいれば、液体タンクが空又は満量になった際に確実に作業者に報知することができる液位報知装置を備えたタンク付車両を得る。【解決手段】高圧洗浄車の液位報知装置は、液体タンクの液面位置の上限液位と下限液位とを検知可能なレベル計と、報知ブザー9と、液面位置が上限液位の高さ以上又は下限液位の高さ以下になった場合、報知ブザー9を作動させる報知回路部20と、を備える。報知回路は、作動中の報知ブザー9を停止可能なブザー停止スイッチ11を有する。液体タンクの液面位置が上限液位以上であることを検出した後に、ブザー停止スイッチが操作されることにより報知ブザー9が停止された場合には、上限液位検出回路の作動が無効にされるとともに、下限液位検出回路の作動が有効な状態に切り換えられる。【選択図】図5
