The new parking system Slimparker 557 offers up to 23 above-ground parking spaces on narrow and long ground plans. A central vertical list located in the transfer area conveys the car to one of the 6 possible parking levels per system. Each parking level can store up to 4 cars. The slim construction contours allows incorporation into a soundproof wall. This safeguards the residents of housing areas against adjacent road and rail traffic noise pollution. Narrow gaps can be used for additional car parking spaces.
