Warehouse System (CLICK TO SEE MOVIE)

This is a more modern version of the pigeonhole system that uses transporters at each level to move the vehicles from the pickup area to the parking area along straight access routes. Modern versions of the warehouse system can operate much faster than the circulation systems but are more complicated. There are two major classifications for this type of system; Platform Operation (CLICK TO SEE MOVIE), sometimes called a sliding platform system and; Conveyor Operation (CLICK TO SEE MOVIE), which uses no platform. Some versions of warehouse systems are capable of parking cars two or more deep on each side. This increases the concentration of vehicles but decreases the retrieval speed when the outside vehicles must be relocated to gain access to the inside vehicles. Intelligent computer programs and good control systems can greatly reduce this sorting time.
