Traffic Protection EVA Safety Rolling Guardrail
Traffic Protection EVA Safety Rolling Guardrail Introduction
The rolling guardrail mainly adopts the "one column and four beams " method . By strengthening the performance and installation method of the column and the fence, it effectively prevents the car from crossing the fence and driving out of the driving lane.
On the other hand, the new anti-collision bucket guardrail has a built-in anti-impact energy-absorbing rotary anti-collision barrel, and the flexible barrel with anti-collision
and energy absorption is mounted on the column, so that the rotating barrel can rotate freely on the column. By the free rotation of the rotating bucket, the impact force of the car is decomposed, and the impact force perpendicular to the direction of the guardrail is decomposed into a direction parallel to the guardrail, so that the impact force is effectively absorbed and reduced by the rotating barrels , thereby effectively reducing the possibility of traffic accidents .
The highway protective rolling guardrail is made of EVA and polyurethane composite. This high-strength EVA and polyurethane material itself has elastic and anti-collision and wear-resistant advantage. It can prevent the rotating barrel from being crushed when it is impacted and effectively protecting the guardrail and the passengers. Besides the well anti-collision and wear resistance, it also has the advantages of chemical corrosion resistance, UV aging resistance, weather resistance, etc. It is not easy to break, and the appearance is exquisite and not easy to fade. Under outdoor natural conditions, the service life is at least ten years.

How safety roller barrier works?
1. The roller barrier converts great shock from vehicle collision to rotational energy to absorb shock.
2. Upper and lower frames adjust tires of large and small vehicles to prevent the steering system function loss.
3. The three-dimensional structure of D-shaped frame and buffering bracket distribute and absorb the 2nd shock.
4. Props at an interval of 0.7 m increase bearing power to prevent accident vehicles from going over the guardrail and turning over into a dangerous area.
5. The product has a rotating barrel made of EVA with excellent shock absorption power, three-dimensional buffering frames and dense props supporting the frames.
