It is conceivable, that a plurality of storage columns 105 and, preferably, all storage columns 105 are equipped with one such spacer device 601 in order to space the storage columns 105 apart from the floor 602 in a vertical direction, allowing a user to clean beneath the respective storage column 105.
  • Fig.6 shows a spacer device 601 in a perspective view without further storage containers 106 arranged on its top 604.
  • the top 604 comprises a plurality of holes 605, which are distributed over substantially the whole surface of the top 604.
  • a cleaning device 617 having a wiper 618 and a pole 619 attached to it is introduced into one of the openings 613 and can be pushed further inward to clean the floor 602 beneath the spacer device 601.
  • a plurality of spacer devices 601 can be provided as a complete bottom layer of a plurality of storage columns 105.
  • the cleaning device 617 can be introduced into all of the spacer devices 601 to clean a floor section reachable through the respective spacer device 601. One floor section after the other can be cleaned by introducing the cleaning device 617 into one row or column of the spacer devices 601.
  • a cleaning device 617 is shown introduced under one spacer device 601.
  • the cleaning device 617 can be pushed beneath a series of adjacent spacer devices 601 by pushing the pole 619 to further advance the wiper.
  • a limited lateral motion of the wiper 618 is also possible.
  • a further cleaning device 617 is shown, which is pushed beneath a series of spacer devices 601 perpendicularly thereto.
  • Fig.8 shows the spacer device 601 having a plurality of engagement elements, which allow a storage container handling vehicle 30, 200 or 300 to handle the spacer device 601 in order to introduce it as a bottom layer.
  • the size of the spacer device 601 should thus correspond to the size of storage cell, and thus to the size of a common storage container 106, such that it can be introduced between the upright members.
  • the size of a storage cell corresponds to the rectangular opening between the rails of the rail system.
  • the storage columns 105 exemplarily comprise removable covers in the form of swivably supported lids 621, which can be opened to access the floor 602 with a cleaning device 617, when required.
  • the lids 621 can remain closed, to prevent large volume flows of air entering the grid from the bottom side. This may be advantageous in relation to a fire risk. It can also prevent rodents from entering the bottom layer.
  • the lids 621 may simply be provided in the form of plates that can be latched between the upright members 102 and be removed again.
