ELECTRIC EXCAVATOR
A high voltage portion (HVP) includes an electric motor and a battery that supplies electric power to the electric motor, the high voltage portion (HVP) being a portion to be subjected to maintenance. An operator's cab is arranged on a revolving frame at a location closer to a front end of the revolving frame than the high voltage portion (HVP). A frontmost end position of the high voltage portion (HVP) is located closer to a rear end of the revolving frame than a rearmost end position of the operator's cab. A switching valve is located between the frontmost end position of the high voltage portion (HVP) and the rearmost end position of the operator's cab in a fore/aft direction.
