Abstract
【解決手段】油圧アクチュエータ20により作動するクローラ型パワーショベル車1を、油圧アクチュエータ20に作動油を供給する油圧ポンプ32を駆動する電動モータ31と、直流電力を供給するバッテリー50と、バッテリー50の直流電力を交流電力に変換して供給することにより、電動モータ31を作動させるインバータ41と、インバータ41により電動モータ31の作動を制御する制御コントローラ40と、バッテリー50からインバータ41に流れ込む負荷電流の大きさを検出する電圧・電流センサ42とから構成し、制御コントローラ40が、電圧・電流センサ42から検出された負荷電流の大きさが、所定の時間継続して所定の閾値を超えたときに、電動モータ31を停止させるように構成する。
