Claim Text:
1. An electrically driven dump truck which elevates a slider ( 4 Ra, 4 La) of a power collector ( 4 R, 4 L) provided on a vehicle ( 1 ) to be movable up and down, places the slider in contact with a trolley wire installed along a lane, and travels by use of electric power received from the trolley wire, comprising: right and left electric motors ( a steering device ( a trolley wire detecting device ( a control device ( the control device calculates at least one representative point of the vehicle and at least one target point situated on the trolley wire based on the relative position information on the electrically driven dump truck and the trolley wire detected by the trolley wire detecting device, sets a fluctuating point which fluctuates with reference to the target point, and executes control to give a yaw moment to the vehicle in such a manner that the representative point approaches the fluctuating point, the control device includes a vehicle control device ( the vehicle control device calculates a yaw moment correction value for giving the yaw moment to the vehicle in such a manner that the representative point approaches the fluctuating point, and the controller controls at least either the right and left electric motors or the steering device by use of the inverter control device and the steering control device based on the yaw moment correction value for giving the yaw moment to the vehicle so as to make the vehicle travel while meandering around the trolley wire.
