PU EVA Rotating Guardrail Anticollision With Galvanized Highway Crash Barrier
PU EVA Rotating Guardrail Anticollision With Galvanized Highway Crash Barrier
The "one column and four columns" method is adopted, and the performance and installation method of the column and the guardrail are strengthened to effectively prevent the car from passing through the guardrail and driving out of the driving lane. And a rotating structure is adopted to support the elastic and anti-collision and wear-resistant rotating barrel on the column, so that the rotating barrel can rotate freely on the column. The impact force of the direction is decomposed into the direction parallel to the guardrail, which is effectively absorbed and reduced by the rotating barrel, thereby effectively reducing the consequences of traffic accidents.

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.
