The following picture shows a system placed in an underground parking garage. This kind of system can be only placed underground if there is sufficient height available.
Other 2 floor systems may be placed with one floor above ground and one floor below ground
(in a pit) where the cars will always be retrieved from the floor that is above ground. The driver parks his car in an open space above ground and the car may be moved without the driver in the car to a space below ground or to an alternative space on the ground.
