The SNT-PSH puzzle parking system is designed with multi-levels and multi-rows. Each level is designed with an empty space for exchanging. All spaces can be lifted automatically except the spaces of ground level and all the spaces can be slide automatically except the spaces of top level.
When a car needs parking or retrieving from one parking space, all parking spaces under this car space will slide to the empty space and form a lifting passage under this space. Then, this parking space can be lifted and down freely. When it reaches the ground level, the car can be parked or retrieved directly.
