Abstract:
A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a hydraulic actuator that drives driven parts including the lower traveling body and the upper turning body, a main pump that supplies hydraulic oil to the hydraulic actuators, a pump motor that drives the main pump, and a power storage device that supplies electric power to the pump motor. When the charging cable is connected to the charging port during the operation of the shovel, the shovel causes the hydraulic actuators to shift to the inoperable state. When the charging cable is connected to the charging port, the shovel does not start the pump motor even if an input for starting the pump motor is received from a user.
