, which includes both dynamic and static. As the city highrise buildings built by the level of housing reform, like parking shift from threedimensional surface parking, parking in a static traffic in the already occupied an increasingly important position. Underground parking garage, pared with the traditional, in many ways is the first section shows the superiority of the advantages of the past, underground garage vehicular access due Leave generous, the average car would occupy 40 square meters of area, If using doubleparking garage, the ground can increase the utilization rate of 80% 90%, if the use of multifloor (21 floor) Threedimensional garage, then the land area of 50 square meters will be placed on the 40 vehicles that can to save land resources and reduce the cost of civil engineering development. For example, the Indonesian Embassy in Beijing did not build multistorey parking before the plane can only put five cars are now built threedimensional lifting and after class garage can park 13 cars, the basic requirements to meet the Embassy . It is generally considered good prospects for parking equipment industry and has been hailed as the 21st century, one of the most popular industry.Lifting and transferring the concept garageParking equipment has provided a total of 9 categories: lifting and class (PSH), simple lifting class (PJS), vertical lifting type (PCS), the vertical circulation category (PCX), flat mobile class (PPY), tunnel reactor stack class (PXD), multicycle class (PDX), the level of circulating type (PSX), vehicle lift (PQS), there are dozens of specifications, can be applied to a different space, site conditions, is a high security , high reliability, high efficiency of automation equipment. Especially in these types of lifting and 9 classes (PSH) parking most widely used. Used to set the rising and falling or sliding vehicle access to vehicles, parking garage equipment category called lifting and garage. Lifting and transferring garage modular design, each unit can be designed as two, three, four, five, halfunderground, and other means, the number of parking spaces from a few to hundreds. As the lifting and transferring the pattern classes more parking, vary in size, strong adaptability to the site, therefore, use of such equipment is mon parking garage. Its working principle is: Each car parking spaces are presented board, set the required access to the vehicle by vehicle plate upward and downward, sliding movement to reach the ground floor, the driver entered the garage, access to vehicles, plete the access process. The upper or lower parking spaces need to traverse the space through the middle layer, will contain the vehicle plate up or down to ground level, the pilot before entering the garage or out a car into the garage.
