What are puzzle parking systems? Puzzle parking systems are semi-automated or fully automatic car parking solutions that work on the basis of stacking and moving the cars together. It works like a sliding puzzle and features pallets that move vertically and horizontally to move vehicles in and out of the system. These are independent parking systems which means that there is no dependency for the retrieval of any car on other cars parked in the system. These systems can be easily designed and customized according to any space requirements. These smart car parking systems are typically powered by electric motors or hydraulic pumps that move vehicles in and out of the parking space.
