ELECTRIC CONSTRUCTION MACHINE
To provide an electric construction machine in which a driver in a cab can check the amount of power storage in a power storage device without removing his or her line of sight from a work device, and can check the amount of power storage in a power storage device even outside the cab.SOLUTION: An electric hydraulic excavator comprises a vehicle body, a work device 3 provided on a front side of the vehicle body, a power storage device, an electric motor driven by the electric power of the power storage device, a hydraulic pump driven by the electric motor, a plurality of work hydraulic actuators driven by the pressure oil discharged from the hydraulic pump to drive the work device 3, and a power storage amount indicator 15 for displaying the power storage amount of the power storage device. The power storage amount indicator 15 is arranged in the work device 3.SELECTED DRAWING: Figure 1
【課題】運転室内の運転者が作業装置から視線を外さなくとも蓄電装置の蓄電量を確認することができ、かつ、運転室外でも蓄電装置の蓄電量を確認することができる電動式建設機械を提供する。【解決手段】電動式油圧ショベルは、車体と、車体の前側に設けられた作業装置３と、蓄電装置と、蓄電装置の電力によって駆動される電動機と、電動機によって駆動される油圧ポンプと、油圧ポンプから吐出された圧油によって駆動され、作業装置３を駆動する複数の作業用油圧アクチュエータと、蓄電装置の蓄電量を表示する蓄電量表示器１５とを備える。蓄電量表示器１５は、作業装置３に配置される。【選択図】図１
