The SP system is designed for locations that require a large number of parking spots and receive a high volume of traffic. Based on a modular concept, the SP can be adapted to meet the specific requirements of any given location. Through the combination of vertical car elevators passing through the entire system and shuttles that work on each individual parking level, the SP boasts a limitless array of possible configurations. The SP provides several hundred parking spots that can be built above or below grade. Transfer rooms can be placed on every level within or above the system. The SP allows for various car heights and its integrated quick change system allows drivers to retrieve cars rapidly, minimizing wait time. The transfer rooms and rotating turntable are arranged to position the vehicle toward the exit, allowing the driver to proceed immediately forward.
