The TrendVario 4000 can be used to park two cars on top of each other; the parking spaces can be shifted vertically or horizontally. No pit is required. The system is a drive-through system and can be combined with the TrendVario 4100, 4200 and 4300 to create an additional parking row. As in combined systems a second driveway is not necessary, the TrendVario 4000 is the ideal solution to increase the number of parking spaces within a given floor space. By selecting a central control element, the parking space selected is moved to the desired position by means of an automatic control system. An empty space allows independent parking. The access level in front of the complete system is secured by doors which can only be opened once the shifting process is completed. Therefore, cars are protected against theft and vandalism. The system offers space from 3 to 29 cars.
