An electric drive dump truck travels by contacting, with trolley lines, power collection units configured to be moved up and down by lifting devices and receiving electrical power from the trolley lines. A position detection device is configured to detect a position of the electric drive dump truck; a vehicle speed detection device is configured to detect a vehicle speed of the electric drive dump truck; and a storage section is configured to store a position of the trolley lines and a time (hereinafter referred to as a moving-up time) until the power collection units contact with the trolley lines since the power collection units start moving up. A control device is configured to output a signal indicating that the power collection units can be moved up based on the position and vehicle speed of the electric drive dump truck, the position of the trolley lines, and the moving-up time.
