The rotating guardrail combines the advantages of traditional
barrier and new type energy -absorption anti-collision roller
barrel. It inserts the anti-collision roller barrel into
strengthened traditional barrier. When traffic accident happening,
the roller barrel can rotate freely on the columns, and through
this free rotation of the roller, they break down the impact force
of the car. 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.
