Silo
Silo Parking System
A silo system is cylindrical in nature, similar to a grain silo. Vehicles are parked at the outer edge of the core. The core is occupied by a lifting/rotating mechanism that accomplishes the vehicle positioning, typically allowing only one vehicle to be manipulated at a time. Silo mechanisms do however allow simultaneous up/down and axial positioning, which can move the vehicles rather quickly.
Though silo systems may be constructed above ground, these parking systems are normally constructed below, giving least issue to poor soil conditions.
Multiple systems may be constructed at the site, allowing an increase in throughput. However since the single center mechanism exists per system, redundancy can be a concern.
