Silo systems are cylindrical systems typically with a single, centrally positioned mechanism used to park and retrieve vehicles. The central mechanism moves vertically and rotates simultaneously allowing the vehicle platform to move to and from one parking spot to another very quickly. Typically silo systems are installed underground, and are most suitable where soil conditions are particularly unfavorable, but can also be installed above ground.
Single or multiple parking modules are possible with silo systems but typically only one vehicle can be parked or retrieved at one time. As there is only one mechanism for parking and retrieving vehicles, and little possibility of adding another, system redundancy can be an issue.
