Abstract

A parking system for automotive vehicles, comprises a building structure divided into a ground parking level and at least two upper parking levels, each having a floor and a ceiling defining between them one or more lines of parking spaces extending longitudinally of the respective level. The floor and ceiling of each level are spaced from each other a distance which is greater than twice the height of the vehicles to be parked in the respective level, to define a lower zone of parking spaces for supporting the vehicles, and an upper zone for conveying the vehicles to a selected parking space in the lower zone.
