An automatic controlled multi-level storage system comprising a storage structure formed of structural steel elements and having an access level and at least one storage level and an elevator space, said access level and each of said at least one storage level having each a plurality of contiguous substantially rectangular spaces, wherein:
- said access level is for moving cargo elements to be stored into a specific individual space on either storage level and retrieving them from the storage structure, having a center space formed into part of said elevator space, two opposite conveying spaces transversely aligned at two opposite sides adjacent to said elevator space, which comprises each a plurality of four-way wheel assemblies arranged in longitudinal direction and controlled to move individual storage platforms and cargo elements thereon into or out of the storage system, three conveying spaces respectively and longitudinally aligned with the aforesaid two opposite conveying spaces and said elevator space at one side, said three conveying spaces each comprise a plurality of four-way wheel assemblies arranged in longitudinal and transverse directions, and three platform storage spaces at an opposite side relative to said elevator space and the conveying space, said three platform storage spaces each comprise a plurality of two-way wheel assemblies arranged in longitudinal direction and controlled to move individual storage platforms into platform storage devices therein:
- said at least one storage level is for storing cargo elements, said at least one storage level having a center space formed into part of said elevator space, two opposite cargo storage spaces transversely aligned at two opposite sides adjacent to said elevator space, which comprise each a plurality of four-way wheel assemblies arranged in longitudinal direction controlled to move individual storage platforms in longitudinal direction from one cargo storage space to another, three contiguous cargo storage spaces respectively and longitudinally aligned with the aforesaid two cargo storage spaces and said elevator space at one side, said three contiguous cargo storage spaces each comprise a plurality of two-way wheel assemblies controlled to move individual storage platforms in longitudinal direction;
- said elevator space is disposed through said access level and said at least one storage level vertically and having elevator means for raising and lowering individual storage platforms and cargo thereon to a desired level, said elevator means comprising two register spaces vertically spaced corresponding to the spacing of the levels of said storage structure, each register space comprising a plurality of four-way wheel assemblies arranged in longitudinal direction, and two opposite mechanical arms at two opposite ends thereof respectively supported on a respective hydraulic lift, said mechanical arms being respectively lowered by said respective hydraulic lift for permitting individual storage platforms and cargo thereon, if any, to be moved longitudinally from either register space to an adjacent space on either level of the storage structure;
- said access level and said at least one storage level each comprises pairs of parallel rails longitudinally and transversely interconnected with one another in directions corresponding to said four-way and two-way wheel assemblies for guiding horizontal rollers on individual storage platforms.
