Combilift 551: The Combilift 551 is a puzzle parking system that has been designed to have two parking levels without a pit and offers independent parking. All the parking spaces within this system are directly accessible from the entrance level by the lifting and sliding motion of the parking platforms. There is always one unoccupied parking space at the entrance level. This system has been astutely designed where the entrance-level platforms move laterally and the upper-level platforms move vertically. When one of the upper platforms is needed for parking in or out, the entrance level platforms are first shifted to one side in order to provide an empty space into which the required upper platform is then lowered.
