More Information
Summary:An upper revolving structure (3) of an electric hydraulic excavator (1) includes an electric motor (13) that serves as a power source, a battery (15) for storing electric power to be supplied to the electric motor (13), a power feeding port (16) to which a power feeding cable (17) for feeding electric power to the electric motor (13) or the battery (15) is connected via a relay cable (18), and a camera (23) that monitors the surroundings of a lower traveling structure (2) and the upper revolving structure (3). The camera (23) is attached to the upper revolving structure (3) in a position higher than the power feeding port (16) to capture an image of the power feeding port (16). With this configuration, it is possible to confirm through a monitor (10) the power feeding port (16), the connecting state of the relay cable (18) with respect to the power feeding port (16), and the treading, the catching-in, or the like of the power feeding cable (17) at the working of the electric hydraulic excavator (1).
