Storage system

A rack storage system, comprising

• a storage with at least two multi-level longitudinally extending storage racks that are laterally separated by an aisle;
• at least two load lifting devices each having a liftable and lowerable transport platform for lifting or lowering storage units;
• guide tracks running in at least some of the rack levels along the rack length of the aisle such that one or more storage and retrieval vehicles are displaceable along the guide tracks for transporting the storage units between the storage racks and the load lifting devices in the corresponding rack levels;
• said guide tracks being arranged in each such level in a way that the storage and retrieval vehicles may fully access the storage racks and each load lifting device by arranging the guide tracks to extend along the aisle and past the load lifting devices;
• and
• at least one conveyor for transporting storage units to and from said load lifting devices;
• wherein the at least two load lifting devices are arranged in a row in a longitudinal direction of a storage rack either within the storage rack itself or in an extension of the longitudinal extension of a storage rack at the same front end circumventing at least one of the load lifting devices by using a free space of an adjacent aisle so as to allow a conveyor connection from the side to an elevator to which a straight conveyor connection at that level is not plausible, and wherein the at least two load lifting devices are connected to the same conveyor;
• and
• wherein a further load lifting device having a liftable and lowerable transport platform for lifting or lowering storage units is arranged in extension of the longitudinal extension of the opposite side of the aisle of the storage rack either within the storage rack itself or at the same front end of the storage being connected to a separate conveyor.

• wherein a further load lifting device having a liftable and lowerable transport platform for lifting or lowering storage units is arranged in extension of the longitudinal extension of the opposite side of the aisle of the storage rack either within the storage rack itself or at the same front end of the storage being connected to a separate conveyor.
