Bi-Directional Parking System  2 Levels


BDP-2 is a semi-automatic parking system, developed by  Mutrade. The parking space selected is moved to the  desired position by means of an automatic control system,  and the parking spaces can be shifted vertically or  horizontally. Entrance level platforms move horizontally  and upper level platforms move vertically, with always one  platform less at the entrance level. By swiping the card or  input the code, the system automatically moves the  platforms in the desired position. To collect a car parked on  the upper level, the platforms at the entrance level will first  move to one side to provide an empty space into which the  required platform is lowered.

BDP-2 mobilizes the existing space by using it the best  possible way. It can be used to park two cars on top of  each other, and offers space from 5 to 29 cars. A driving  lane in front of the full width of the system is required to  access all parking spaces, and one vacant space on the  entry level allows for horizontal or vertical shifting of all  platforms.  

The access level can be secured by doors which can only  be opened once the shifting process is completed.  Therefore, cars are protected against theft and  vandalism.

Powder coating is applied as a free-flowing, dry powder. It is  typically applied electrostatically and is then cured under heat  to allow it to flow and form a "skin". It is usually used to create a  hard finish that is tougher than conventional paint.

According to the operation principle of our parking system, the periodical maintenance should be fulfilled as per the  following four types: 

A.Monthly inspection and maintenance It should be done every two weeks after project starts to operate within the fifirst three months. The equipment and safety devices should be clean, lubricated adjusted inspected. Especially, please pay more  attention on the working status of main safety devices, careful inspection is necessary and please fifix any problem  found out in the earliest time. Do inspection on every lubrication parts, and lubricate it if needed. 

B.Quarterly inspection and maintenance It should be done every three months after fifirst moths end. All the transmission parts (steel cables, limit switches, motor in power pack, pulleys, guiding rails, etc.), safety devices  and electrical control system should be inspected completely, and do necessary adjusting or fifixing work if needed. 

C.Yearly inspection and maintenance A technical inspection of whole equipment (including earth connection and withstand voltage of electrical parts, etc.)  should be done every year, and customer need make estimation on working status of equipment and annual  maintenance plan, fifix and replace the worn parts. 

D.Adjusting test The adjusting test with loading should be done every two years. The equipment could start to operate only after  careful inspection on whole system if there is long time stop or any earthquake, fifire happening.
