PVC Yellow Road Rolling Barrier
1. Product Introduction
Rolling system with "one upright four guardrails", can prevent the
car through the fence, out of the driving lane effectively by
strengthening the performance and installation of upright and
guardrails. Rolling system use a rotating structure, install the
roller barrier on the upright and make it rotate freely. This free
rotation can disassemble the force of percussion from the car. And
it will be adsorbed and reduced by the roller barrier effectively.
So it can decrease the influence caused by traffic accidents.
rolling system will create a new traffic protection way.

3. How safety roller barrier works?
1. The rotating barrel 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. |
