HYBRID WORK MACHINE
PROBLEM TO BE SOLVED: To reduce a speed of a hydraulic actuator for a particular operation by a work machine, and to achieve elongation of a life of a power storage device.SOLUTION: A hybrid work machine comprises a limit control part. When predetermined one or more work operations (hereinafter, referred to as specific operation) of plural work operations, which are performed by the hybrid work machine, are performed in the case that a degree of degradation of a power storage device becomes higher, the limit control part reduces a speed of a hydraulic actuator at a ratio to the degree of degradation of the power storage device, which has been previously determined for the specific operation.SELECTED DRAWING: Figure 8
【課題】作業機械による特定の動作に対して油圧アクチュエータの速度を低減し、蓄電装置の長寿命化を図る。【解決手段】ハイブリッド作業機械は、蓄電装置が劣化する傾向の度合いが高くなった場合、ハイブリッド作業機械が行う複数の作業動作のうち、予め定められた１以上の作業動作（以下、特定動作と記す）が行われたときに、特定動作に対して予め定められた、蓄電装置が劣化する傾向の度合いに対する比率で、油圧アクチュエータの速度を低減する制限制御部と、を備えている。【選択図】図８
