Hot-selling EVA material road rotating anti-collision barriers, can
be customized according to needs
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.
