Roller Barrier Collision diagram:
Roller Barrier System combines the advantages of traditional
barrier and new type energy -absorption anti-collision roller. It
inserts the anti-collision roller into strengthened traditional
barrier. When traffic accident happening, it can efficiently
resolve the impact energy by converting the impact energy to
rotational energy and pull the accident car back to normal motion
trail.
