1. A driverless automatically guided transport vehicle for transporting a load comprising:
a lifting apparatus which is configured to lift the load such that said load can be transported in the lifted state;
a lifting shaft of the lifting apparatus, which extends in a transverse direction and having at least one rotatably mounted eccentric element at each opposing end;
at least one load carrier element of the lifting apparatus which is height-adjustable relative to a chassis of the vehicle, and which serves for carrying the payload, wherein the at least one load carrier element defines at least one aperture through which the lifting shaft extends;
an eccentric drive to implement a lifting operation of the lifting apparatus; wherein the at least one rotatably mounted eccentric element introduces a lifting force into the load carrier element during the lifting operation; and
at least one straight peripheral portion of the aperture extending in a lifting direction configured for guidance of the load carrier element in the lifting direction and for support transversely with respect to the lifting direction on the lifting shaft.
