PROBLEM TO BE SOLVED: To provide a hybrid wheel loader capable of deriving power from power, which is required for excavation, from an engine, even when there is fear that the power during excavation work is insufficient because a revolving speed of the engine is low.SOLUTION: A hybrid wheel loader includes a control device 200 which estimates output power of an engine 1 and a power storage device 11 when estimating that it travels toward an excavation object so as to perform excavation work, on the basis of output values of detectors 62 and 63, and which accelerates the engine 1 to a target engine speed while increasing electric power for being supplied to a traveling motor 9 from the power storage device, when the output power falls short of target power required for the excavation work.

    【課題】エンジン回転数が低く掘削作業時のパワー不足が懸念される場合にも、掘削に必要なパワーをエンジンから引き出せるハイブリッド式ホイールローダを提供する。【解決手段】掘削作業のために掘削対象に向かって走行していると検出器62,63の出力値に基づいて推定した場合に、エンジン1および蓄電装置11の出力パワーを推定し、出力パワーが掘削作業に必要とされる目標パワーを下回っているとき、蓄電装置から走行電動機9に供給する電力を増加しつつ、エンジン1を目標回転数まで加速する制御装置200を備える。【選択図】図7
