Guide-able road guardrail crash mat

An anti-collision pad is another name for an anti-collision block, buffer pad, rubber block, etc.The cushion is mainly installed at the edge of the loading and unloading platform, which facilitates the parking of trucks and reduces the difficulty of parking for drivers. It plays a role in protecting the platform, loading and unloading equipment of the platform and trucks from damage.
Anti-collision adhesive is one of the necessary protective devices for unloading platform. Craps made of material and process rubber are usually applied to the entire front edge of the cargo platform, while craps made of natural rubber (the same material as automobile tires) are usually used to fix both sides of the loading and unloading position equipment.
Anti-collision cushion is a device that can stop the vehicle safely and change the driving direction of the vehicle to avoid serious injuries to passengers by absorbing the collision energy of the vehicle. Its main function is to reduce the severity of the accident. On the other hand, it also plays a warning and inducing role through its surface color and graphic symbols.

There are many kinds of anti-collision pads, which can be divided into kinetic energy principle and momentum conservation principle according to the anti-collision principle. Kinetic energy principle Collision cushion absorbs the kinetic energy of the vehicle by cushioning or absorbing energy through the destructible or plastic deformed material or structure set in front of the collision object. This structure needs rigid support or obstruction to make the energy absorbing material or structure deform to reduce the impact force on the vehicle.
According to the law of momentum conservation, the other is a structure that transfers the momentum of the runaway vehicle through some sand and water containers set in front of the anti-collision object and plays a buffering role.
This kind of structure has strong flexibility in construction and is more convenient in application.

The structure of the cushion Kinetic energy principle anti-collision pad is generally composed of the end, energy absorbing material, both sides of the beam, diaphragm and back support. After a vehicle collides with the anti-collision pad, it absorbs the energy of the colliding vehicle through the deformation of the end part and energy absorbing material, and the back support is used to resist the impact force of the vehicle.
Energy absorbing material is generally foam material or rubber material, the principle of the anti-collision pad for the front and side of the vehicle has a good effect of energy absorption and guidance, and the system after the collision, the main components can be reused, convenient and fast maintenance and low cost, the disadvantage is a little more complex and high cost of the initial installation.
The principle of momentum conservation is generally composed of sand filling or water filling anti-collision cylinders (piers) of different masses arranged in a certain order. After a vehicle colliding with the anti-collision cushion, the momentum of the vehicle is transferred to the anti-collision cylinder in turn, which reduces the speed of the vehicle and the anti-collision cylinder in turn, and finally makes the speed of the vehicle lower than 15km/h.

★ Collision cushion for guiding structure, the internal use of the latest energy absorption design, the energy absorption unit is box-like design, in the periphery of the four surfaces of the energy absorption unit are all cloth. With different number of deep folds, the energy absorption unit is guaranteed to contract along its axis under the action of folds when subjected to axial impact force.
★ The guide at the bottom of the anti-collision pad for large diameter thick wall seamless steel tube processing, its own high strength can effectively prevent the whole anti-collision pad compression deformation guide. Cracking and breaking affect the smooth contraction of the energy absorption unit to ensure the cushioning function of the cushion.
★ Cushion construction installation is simple, the overall use of front and rear flange planting bar way, the application of high strength planting bar bolts, to ensure the strength of the planting bar.
