The earliestparking system was in the United States in the last century. With the development of The Times, the total number of vehicles in various countries has been increasing in the following decades. This technology has been widely used in Europe, America and Asia, including Japan and South Korea. These countries and companies from the early 1960 s to develop and use can maximize the use of space’s mechanical parking system hod also has a perfect system. There are many different types, such as lift and traverse, roadway stacking, vertical lift and so on. With the continuous increase of family cars, the problems of conflicts between public places and community cars and crowded green space will be more and more prominent. When people’s awareness of life quality and environment is continuously enhanced, “garage” is becoming a hot topic, and mechanical automated parking system will play a great role in the new development of real estate and commerce. With the development of the society, people pay more and more attention to the traffic condition of the city. In front of the car growing in all large and medium-sized cities, more and more blocking traffic, countries have made a lot of investigation and research, finally realized that to maximize the dynamic traffic renovation and management at the same time, also want to strengthen the management of static traffic, from the market demand, the price is feasible and policy guidance, market consumption has been to normal. At present, major cities in China, such as Beijing, Shanghai and guangzhou, have come out of the situation of low utilization rate of parking system. To fundamentally solve the parking problem in cities, the universal promotion of three-dimensional parking system is an inevitable trend.
