The equipment is designed with multi-levels and multi-rows and each level is designed with a space as an exchanging space. All spaces can be lifted automatically except the spaces in the first level and all the spaces can slide automatically except the spaces in the top level. When a car needs to park or release, all spaces under this car space will slide to the empty space and forms a lifting channel under this space. In this case, the space will go up and down freely. When it reaches the ground, the car will go out and in easily.
