BATTERY-POWERED WORK MACHINE
To provide a battery-powered work machine capable of performing work while avoiding a state in which charging equipment cannot be reached.SOLUTION: A controller 10 controls an inverter 52 so that the rotation speed of an electric motor 1 is maintained at the target rotation speed when the remaining amount of a battery 51 falls below the preset first threshold value, operates a first notification device 61a and switches traveling motors 3f and 3g to the traveling first speed side having a large capacity regardless of the input from a traveling mode indicating device 71.SELECTED DRAWING: Figure 3
【課題】充電設備までたどり着けなくなる状態を回避しながら作業を行うことができるバッテリ式作業機械を提供する。【解決手段】コントローラ１０は、バッテリ５１の残量が予め設定された第１閾値を下回ったときに、電動機１の回転数が目標回転数に維持されるようにインバータ５２を制御すると共に、第１報知装置６１ａを作動させ、走行モード指示装置７１からの入力に関わらず、走行モータ３ｆ，３ｇを押しのけ容積が大容量となる走行１速側へ切り換える。【選択図】 図３
