Electrically driven dump truck

According to the present invention, a vehicle control unit (50), a controller (100), an inverter control unit (30), and a steering control unit (32) constitute a control unit (200) that controls elevation of sliders (4La, 4Ra) of current collectors (4L, 4R) based on data detected by a trolley line sensing device (camera) (15). The control unit (200) calculates a positional relation between the sliders and trolley lines (3L, 3R) based on the data detected by the trolley line sensing device. If the sliders are out of a predetermined range of contact with the trolley line, operation to elevate the sliders is prohibited. If the sliders have been already elevated, the sliders are controlled so as to be lowered. In this way, an electrically driven dump truck is provided, which can reduce the operational burden of a driver during trolley driving.
