Application
1. Small radius curve section
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.
2.Tunnel entrance transition
The different widths of roadbed (bridge) and tunnel cross-sections are important reasons for the high number of accidents at tunnel entrances, which require the transition of guardrails to complete the cross-section change. The rolling barrier is used in the tunnel entrance, which can provide a strong enough guidance function to assist the driver to complete the road environment change under the premise of ensuring the collision prevention demand.
3.Interchange exit triangle end
The interchange exit is sensitive to the direction of travel, requiring the driver to choose the correct route based on the judgment of the guiding information, and the poor combination of interchange exit lines will easily cause the driver to hesitate in making decisions before the exit triangle end, which is an unfavorable factor affecting operational safety. Statistics show that interchange exit sections are often accident-prone, so it is advisable to use rotating movable guardrails to strengthen the guidance and protection of the exit area.
4. Where are the safety roller barrier used for?
1. Curved Median Strip
2. Curved Ramp
3. Diverging Point
4. Curved Tunnel
5. Curved Downhill
6. Passge Intersection
7. School Zone
8. Danzer Zone etc.
