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.

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.

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.
