Why is the height limit for mechanical parking spaces 1.55 meters?
2 Answers
Because the relevant regulations stipulate that the height limit for mechanical parking spaces is 1.55 meters. Mechanical parking space: A mechanical parking space is a movable, non-independent space that relies on the overall operation of the machinery and the exchange of spaces to achieve individual parking space usage. In terms of ownership, a parking space is a fixed, independent space with specific boundary requirements, including building area and height specifications, which significantly differ from mechanical parking spaces. Automobile: According to the latest national standard in China, "Terms and Definitions of Types of Motor Vehicles and Trailers," an automobile is defined as a non-track vehicle powered by an engine, with four or more wheels, primarily used for: transporting people and/or goods; towing vehicles that transport people and/or goods; and for special purposes.
I've always been curious about the height limit of mechanical parking spaces, as I drive regularly and have studied the engineering principles behind similar equipment. The 1.55-meter height restriction for mechanical parking spaces is primarily determined by system structure and cost-effectiveness. Firstly, mechanical devices such as lifts and turntable arms require certain clearances to operate; vehicles that are too tall risk scraping against the frame or gears, causing damage. Secondly, the design accounts for the fact that most family sedans range between 1.4 to 1.5 meters in height, with the 1.55-meter limit providing a 10-centimeter buffer for roof racks or antennas to prevent accidental collisions. Additionally, from a maintenance perspective, oversized vehicles increase system load, shorten chain lifespan, and lead to higher repair frequency. Therefore, the height limit is a measure to balance safety and efficiency, ensuring the equipment operates smoothly for years while preventing extra costs for car owners.
