ABSTRACT:
There are provided with an electric motor driven by a battery, a hydraulic pump driven by the electric motor, a proximal actuator for actuating a working member by working oil from the hydraulic pump, a hydraulic motor for moving a working machine body, and an operating lever which can be operated between a neutral position and an operating position. There are provided with a control valve capable of cutting off a supply of working oil to the proximal actuator in a state where operating lever is positioned at an operating position, and a battery capacity sensor for detecting the capacity of the battery. There is provided a controller for outputting a control signal for cutting off a supply of working oil to the proximal actuator to the switching control valve in a state where the battery capacity value detected by the battery capacity sensor is at a level lower than a preset battery capacity reference value. It is possible to positively prevent the machine from being immoved at the working site.
