Electrically driven work machine

An electrically driven work machine comprising:

• an electric motor that is a prime mover;
• an inverter that controls the electric motor;
• a power feed system that supplies power to the inverter;
• a driving battery device that stores the power supplied from the power feed system, and supplies the power to the inverter;
• a control battery that supplies power for control for the inverter, the power feed system, and the driving battery device;
• and
• an opening-closing cover that covers the power feed system, wherein
• the electrically driven work machine includes a control power interruption device that interrupts supply of the power for control with respect to the inverter, the power feed system, and the driving battery device in conjunction with opening of the opening-closing cover;
• a sensor that detects opening of the opening-closing cover,
• a base frame,
• a cab that includes an operation seat and is mounted on the base frame,
• a rotating shaft that joins the cab to the base frame and is disposed at a front part of the cab so as to allow a rear part of the cab to rise and lower, and
• a machinery room that is interposed between the base frame and the cab, and houses the power feed system and the inverter,
• the cab is the opening-closing cover and is formed to tilt up and down with use of the rotating shaft as a fulcrum to open and close the machinery room,
• the sensor is disposed at a position closer to the rotating shaft with respect to the inverter and detects a tilted-up state of the cab,
• the control power interruption device interrupts supply of the power for control with respect to the inverter, the power feed system, and the driving battery device when tilt-up of the cab is detected by the sensor, and
• the inverter is disposed at a rear part of the machinery room.
