Abstract

A stack operating vehicle for storage and retrieval storage units. One embodiment of the stack operating vehicle comprises a first bearing device with a first bearing base and a first holding device for handling at least one storage unit; a second bearing device with a second bearing base and a second holding device for handling at least one storage unit. The second holding device is movably supported by a guiding device along a horizontal direction; a vertical guide arrangement at which the first bearing base and the second bearing base are respectively guided on an adjustment path along the vertical direction which are formed such that the first bearing base and the second bearing base overlap one another over their entire adjustment paths in the vertical direction. The disclosure also relates to a method for execution of storage orders with storage units with such a stack operating vehicle.

wherein the first guiding device (V 10 ), by which the first holding device ( 69 ) is movably guided at the first bearing base ( 60 B), comprises a guide track (V 11 ) which is formed at the first bearing base ( 60 B) and a guidance part (V 12 ) which is movably guided at the guide track (V 11 ) and which is connected to the first bearing base ( 60 B).

3. The stack operating vehicle (F) according to claim 1 , wherein the stack operating vehicle (F) comprises:
a support structure ( 40 ) to which the vertical guide arrangement ( 50 ) is mounted; and
a movement device ( 10 ) for movement of the stack operating vehicle (F) on a runway, wherein the movement device ( 10 ) is mounted at the support structure, wherein the support structure ( 40 ) extends in the vertical direction (ZA) when starting from the movement device ( 10 ).

4. The stack operating vehicle (F) according to claim 3 , wherein the first height adjustment device ( 70 ) and the second height adjustment device ( 90 ) are arranged at or integrated into the support structure ( 40 ).

5. The stack operating vehicle (F) according to claim 1 , wherein:
the support structure ( 40 ) comprises a first support part ( 41 ) and a second support part ( 42 ); and
the guide arrangement ( 50 ) comprises at least a first guide track ( 53 ) in which a first support part ( 55 ) which is mounted to the first bearing base ( 60 B) and a second guidance part ( 85 ) which is mounted to the second bearing base ( 80 B).

6. The stack operating vehicle (F) according to claim 5 ,
wherein the guide arrangement ( 50 ) additionally comprises a second guide track ( 54 ) positioned at a distance from the first guide track ( 53 ) in a width direction (XA) of the guide arrangement ( 50 ),
