A special load handling device moves vertically between two directly opposite storage columns, moving trays or containers between the storage compartments and a transfer point using a pulling technique. In addition to systems with fixed compartment heights within the storage column, systems with flexibly definable compartment heights are also designed. Instead of fixed storage compartments, a grid is created for the trays with a grid dimension into which the trays are inserted. This makes it possible to adapt the storage compartment heights to different goods and thus optimize volumes, especially with varying load unit heights.
