Factory Nice Road Safety Highway Guardrailhighway Guardrail
1. Features of the Rotating Crash Barrier:
Function 1) and function 2) are the anti-collision function of the
guardrail. The anti-collision function of the guardrail is the
function that should be possessed to prevent the vehicle from
rushing out or turning over the road or under the bridge when a
large vehicle collides with the guardrail, causing a serious and
vicious accident. .
Function 3 is the guiding function of the guardrail. The guiding
function of the guardrail means that the vehicle can be correctly
guided after the collision. The collision vehicle should not drive
into the adjacent lane as much as possible within a certain
distance, and it should be able to effectively block the vehicle
and guide the vehicle. If the vehicle crosses, climbs, rides, or
goes under the guardrail in any form, the vehicle should maintain a
normal running posture after the collision, and no sideways,
U-turns, etc. will occur.
Function 4) is the buffering function of the guardrail. The
buffering function of the guardrail means that the guardrail can
absorb the impact energy through its own deformation, or promote
the energy conversion of the vehicle through the guardrail
guidance, increase the release time of the impact energy, and
decompose the buffering collision process to reduce vehicle damage.
occupant injury.

Product Structure
Parts and Installation:
1) Column: It is driven into the roadbed and is the main
force-bearing component.
2) Beam: It is used for the connection between the columns and to
fix the rotating barrel.
3) Rotary barrel: It is fixed between the upper and lower beams and
can be rotated around the column. The main materials are EVA
(ethylene-ester acid copolymer) and polyurethane.
4) Sleeve: installed on the inner wall of the rotating barrel, the
contact part of the rotating function.
5) Gyratory ring: Installed between the rotating barrel and the
beam to balance and promote rotation.
6) Connecting frame: used for connection between beams.
7) U-shaped frame: connect the beam and the column to fix the beam.
8) Pad buckle: Lined with the beam and connected to the U-shaped
frame.
9) Hoop: connecting beam and column, used to fix the beam, suitable
for specific models.
10) Reflective strips.•It is a reflective film, which is pasted on
the rotating barrel and plays an inductive role.
