Abstract: A mechanical-storage multi-level carpark includes a gantry structure formed by a set of uprights and crossbeams, defining a space inside which a vertical carrousel structure is supported, which is provided with car housing support.

Abstract: A rotary storage structure (10) has a supporting frame (12) provided with circular tracks (29, 35) provided with rollers (31) which support independently rotatable sub-frames (15, 16). Each sub-frame (15, 16) is provided with pairs of co-axial rings (36) which support self-righting storage platforms (37) for items (e.g. motor vehicles) loaded into, or from, the structure (10) from loading platforms or ramps (44). A cable drive (42) is provided to rotate each sub-frame (15, 16) to enable the storage platforms (37) to be positioned adjacent the loading platforms or ramps (44).

Abstract: This invention relates to a beehive type mechanical three dimensional rotary parking structure for passenger cars comprising a circular casing, a plurality of parking compartments rockably deployed inside the circular casing, an axle fixed in the center of the circular casing, a driving means for rotating the casing, a set of rotary guide rails for the casing to rotate freely without resistance, and a support means with bearing type rollers and supporting rail. Considering the proportion of the area of land required to the capacity of the parking structure, this new type structure can accommodate more cars than ordinary ones. The larger is its capacity, the more land space can be saved and the easier is its administration. Therefore, this invention helps in solving the parking problem of a modern city.
