Vertical parking lots were installed in several cities during the 1920s
During the first half of the 20th century, cars became more and more accessible. This led to a severe parking crisis in bigger industrial cities. Therefore, in the 1920s, car elevators were installed to fit more vehicles in smaller spaces. This picture was taken in 1932, in Chicago.
It operated in a similar way to a Ferris wheel. The cars were parked in cages that were attached to a belt, and they rotated. A car would park and be lifted upwards, and the next space would slot in at the bottom. They were powered by electric motors or hydraulic pumps.
