Abstract

【課題】還元剤の残量が少なくなったときでも必要な動作を支障なく実施することができる建設機械の提供。 【解決手段】エンジンと、油圧シリンダ１８、油圧モータ２０を含む複数のアクチュエータと、エンジンの排ガス中の窒素酸化物を浄化処理する排ガス処理装置とを有する油圧ショベルにあって、還元剤残量検出装置３３によって還元剤貯蔵タンク３０内の還元剤の残量が所定残量以下となったとき、油圧シリンダ１８によって駆動するフロント作業機の機能の発揮が難しくなるように油圧シリンダ１８の作動を規制する規制制御と、このとき油圧モータ２０によって駆動する走行体１、旋回体３の機能が発揮されるように、この油圧モータ２０の作動を可能に保持する保持制御とを実施するアクチュエータ作動制御手段を備えた構成にしてある。
