the vertical stacking parking carousel system is back! New York based Parkmatic is making and installing them

Vertical parking devices, like the steel stacking shelves that hold several cars, are common around the city, but a new vertical parking system that can turn two street-level parking spaces into a dozen has come to Brooklyn.

Three 43-foot-tall steel structures from Parkmatic, specialists in mechanical and automated parking systems for more than 20 years, were recently installed to simplify vertical parking by stacking cars on an automated Ferris wheel of sorts and has increased the capacity of the Brooklyn lot almost 30 percent.

The difference between Parkmatic’s carousel and standard space-maximizing devices is that it doesn’t require moving vehicles out of the way to get to other cars. In a typical two-, three- or four-high stacker, the bottom vehicles must be moved out of the way so the top shelves can be lowered to the ground.
