To provide an electrically driven work machine that can reduce power consumption regarding electrically driven work machines whose driving power supply is a battery.SOLUTION: The electrically driven work machine includes a battery 62, an electric motor 7 whose driving power supply is the battery 62, a hydraulic actuator whose hydraulic source is a hydraulic pump 113 driven by the electric motor 7, a cutoff lever that limits the operation of the hydraulic actuator by stopping pilot pressure for operating the hydraulic actuator, an electric cooling pump 651 that circulates a coolant in coolant passages for cooling electrical equipment including the battery 62 and electric motor 7, an electric cooling fan 652 blowing cooling air on a radiator provided on the coolant passages, and a system controller 67 that stops the electric motor 7, the cooling pump 651, and the cooling fan 652 when receiving a command for limiting the operation of the hydraulic actuator while the cutoff lever is rotated upwards.SELECTED DRAWING: Figure 4

    【課題】バッテリを駆動電源とする電動式作業機械において、電力の消費を抑制できる電動式作業機械を提供する。【解決手段】バッテリ62と、バッテリ62を駆動電源とする電動モータ7と、電動モータ7によって駆動される油圧ポンプ113を油圧源とする油圧アクチュエータと、油圧アクチュエータを操作するパイロット圧を遮断することにより油圧アクチュエータの操作を制限するカットオフレバーと、バッテリ62と電動モータ7を含む電装品を冷却するための冷却水路に冷却水を循環させる電動式の冷却ポンプ651と、冷却水路上に設けられたラジエータに冷却空気を送風する電動式の冷却ファン652と、カットオフレバーが上方に回動されて油圧アクチュエータの操作を制限する指令を受信した場合に、電動モータ7、冷却ポンプ651、及び冷却ファン652を停止させるシステムコントローラ67と、を備える。【選択図】図4
