Abstract

The article transport device includes a transport vehicle configured to move back and forth between a receiving location and a delivery location, and a load receiving base that is provided at at least the receiving location. The transport vehicle includes a transport placing base on which an article is to be placed, and a lift device configured to raise and lower the transport placing base to a first height and to a second height that is lower than the first height. The load receiving base is a base on which an article is to be placed, and is fixed at a third height that is between the first height and the second height. When the transport vehicle performs restoration movement to move from the delivery location to the receiving location, the lift device performs a restoration operation that differs in accordance with whether or not an article is present on the load receiving base at the receiving location.
