Abstract: A multilevel modular storage system composed of a plurality of modules arranged side by side and stacked on a plurality of levels which can slide horizontally and transversely in both directions. Each module has a substantially rectangular elongated supporting base. A first end of each one of the modules can slide on sliders which are rigidly coupled to a wall, while the other end is supported by vertical uprights which are substantially shaped like an inverted L and rest on a floor rail. The entire storage system has a motor drive which allows the translatory motion of the modules of each level so as to provide top and/or front access to the item of interested, both for loading and unloading the products to be stored or removed.
