Description
Technical Field

[0002] In highway engineering, a large number of bridges are often built to cross rivers, valleys, etc. Due to the restrictions of the rules and functions of the bridges, some vehicles that do not meet the regulations are not allowed to drive on these bridges.

Therefore, it is necessary to set up height limit devices to prevent vehicles that do not meet the regulations from passing through, thereby ensuring road safety. However, the current height limit devices are all rigidly connected to the bridges. If a vehicle is too high, it will collide strongly with the height limit pole, resulting in the immediate damage or collapse of the height limit device after being hit, and it will also cause great harm to the people in the vehicle. Moreover, when adjusting the height of the existing height limit devices, workers need to climb to the upper part for adjustment, which will delay time in case of an emergency.
