AI Technical Summary
The existing height-limiting gantries are prone to causing traffic accidents when oversized vehicles collide with them, and the maintenance costs are high, making it difficult to effectively protect traffic facilities and driver safety.
Design a height restriction frame that uses a crossbeam structure connected by a rotating rod and low-strength bolts. The low-strength bolts break or deform first under the impact of over-height vehicles, causing the crossbeam structure to flip over, thus preventing the rotating rod and mounting rod from deforming or breaking. Local maintenance can be achieved by replacing the low-strength bolts, reducing maintenance costs.
It effectively prevents severe deformation and parts scattering of the height restriction frame after being impacted by oversized vehicles, reduces maintenance costs, extends the service life and safety of the height restriction frame, and avoids traffic accidents.
