Warning Film Anti-Collision Device Crash Barrier Highway Crash Attenuator
The rear collision absorption device of the vehicle is used to prevent the heavy casualties and losses caused by the rear collision of the vehicle. The vehicle equipped with the anti-collision device can greatly reduce the accident injury after being hit by the rear vehicle, and the effect is obvious.

Principle: the device can absorb the impact force through its internal material deformation, which can effectively absorb the impact force and reduce the damage. At the same time, it can also prevent the rear car from crashing into the bottom of the car and protect the safety of the rear car personnel.

Product Knowledge Q&A
What is this product used for?
Answer: It is a "safety airbag" installed on the rear of engineering vehicles (such as sweeper trucks, water trucks, etc.). It serves two main purposes:
Warning and alerting: The yellow body, reflective strips, and flashing lights make it highly visible to vehicles approaching from a distance.
Crash absorption and energy dissipation: In the event of a rear-end collision, it acts like a "sponge" to absorb impact force, preventing the following vehicle from sliding under the host vehicle and protecting the safety of occupants in both vehicles.
What materials is it made of? Is it durable?
Answer: The outer shell is made of aluminum plate, and the interior consists of specially designed aluminum honeycomb energy-absorbing material (protected by an invention patent). Instead of rigidly resisting impact, it dissipates collision force through scientifically engineered deformation. It has been tested and proven reliable.
How is it installed?
Answer: It’s very simple. It can be directly fixed to the rear of the vehicle using the provided bolts. There are mobile versions with wheels (for easy relocation) and directly fixed versions.
Can the size and color be customized?
Answer: Yes. The standard width is 1.85 meters, but customization of size and color is supported to accommodate different vehicles.
