The speed of the car's blocking lever is directly related to its own weight. Generally, the heavier the falling speed of the car body, the slower the required energy consumption. The carbon fiber sluice gate has the advantages of high strength, light weight, and rapid landing. The average 2.5-meter long landing gear takes 6 seconds to rise and fall, and the same length and size of the carbon fiber landing gear has a maximum take-off time of only 2.3 seconds. Its application can effectively solve the shortcomings of slow rise and fall of high-speed ETC. This is especially suitable for high-efficiency electronic identification parking systems, especially during peak traffic hours, which can effectively reduce the waiting time for vehicles to enter and exit, and improve service.
