AUTOMATICALLY OPERATED EXCAVATOR
A technique by which energy consumption of the excavator is further reduced, is provided. An excavator according to an embodiment of the present disclosure includes a hydraulic actuator; a main pump 14 configured to supply hydraulic oil to the hydraulic actuator; a pump motor 12 configured to drive the main pump 14; an operation device 26 of an electric type configured to operate the hydraulic actuator; and an inverter 18A configured to control the pump motor 12, wherein in response to determining that the operation device 26 is not operated, the inverter 18A causes the main pump 14 to automatically stop, and subsequently, in response to determining that an operation with respect to the operation device 26 is started, the inverter 18A causes the main pump 14 to be automatically activated.
