Patent attributes
A pallet transport apparatus within a rack installation oriented orthogonally with a longitudinal x direction, a transverse z direction and a vertical y direction has a travel route in the x direction and in the z direction. In the apparatus, an x traveling mechanism/x wheel units and a z traveling mechanism/z wheel units are designed so as to be vertically moveable in the y direction mechanically independently of one another. The apparatus has an x lifting device for lifting the x traveling mechanism or of the x wheel units in the y direction, a z lifting device for lifting the z traveling mechanism or of the z wheel units, and a y lifting device for moving the pallet pickup unit. The x/z lifting devices can be activated in the y direction independently of one another and independently of the y lifting device.
