Abstract
A transport vehicle equipped with a current collector, includes: a vessel to load a load; a current collector that extends to receive electric power from an overhead line and contracts and retracts so as to be disposed away from the overhead line; and a vehicle body that rotationally drives driving wheels by at least one of the electric power from the current collector and a self-propelled driving source and on which the vessel is placed; a pantograph position detector that detects a relative position of the current collector and the overhead line; and a control device that controls a driving direction of the vehicle body or gives an instruction of information with which a direction in which the vehicle body is to be operated can be recognized, so that the relative position is brought to a position where the current collector and the overhead line are connected.
