Highway Safety Roller Anti Collision Barrier Low Friction

Highway safety roller anti-collision barrier

The safety roller barrier is a new product. It is assembled with PU / EVA rollers and galvanized steel post and beams. The roller barrier differs from the w beam guardrail in the way it functions because It can absorb shock and lead vehicle to the road direction by roller, to prevent large accidents, whilst the W beam does not. The roller barrier is as well lighter and easier to install than w beam guardrail and it would be easier for recovery after attachment and easier to repair.
The guardrail is composed of columns, rotating cylinder, u-beam and connecting parts. All steel components are treated with hot-dip galvanized anti-rust treatment.The vertical column is separated by 1m or 0.7m, and two rotating cylinders are installed on each vertical column. This rotating cylinder takes EVA as the main material, and 17 auxiliary materials such as PE and related chemical additives are added.Continuous working temperature is between 60 ° and 70 °.These kinds of guardrails are usually installed on the ramp, continuous downhill and curved road of the expressway. When a vehicle hits a guardrail, the rotation function of the rotating cylinder itself and the good resilience of the cylinder body can greatly reduce the injury degree of the vehicle and the driver, and play a good protective role.There is a reflective strip on the rotating cylinder, and the evening star stone can reflect the outline of the route better through the light irradiation, which can play a good line of sight induction effect on the vehicle and further guarantee the safety of the vehicle.

How safety roller barrier works?

1. The roller barrier converts great shock from vehicle collision to rotational energy to absorb shock.

2. Upper and lower frames adjust tires of large and small vehicles to prevent the steering system function loss.

3. The three-dimensional structure of D-shaped frame and buffering bracket distribute and absorb the 2nd shock.

4. Props at an interval of 0.7 m increase bearing power to prevent accident vehicles from going over the guardrail and turning over into a dangerous area.

5. The product has a rotating barrel made of EVA with excellent shock absorption power, three-dimensional buffering frames and dense props supporting the frames.

Working principle of safety anti-collision bucket roller barrier

The rolling guardrail for expressway protection mainly adopts the method of "one column and four beams". By strengthening the performance and installation of the columns and fences, the impact energy of the car's impact is converted into the kinetic energy of the car moving forward, thereby effectively preventing the car from crossing the fence and leaving the lane.

On the other hand, the new anti-collision barrel guardrail has built-in anti-shock energy-absorbing rotating anti-collision barrel, flexible anti-collision barrel

The energy absorbing device is installed on the column so that the drum can rotate freely on the column. Through the free rotation of the rotating bucket, the impact force of the trolley is decomposed, and the impact force perpendicular to the direction of the guardrail is decomposed into a direction parallel to the guardrail, so that the impact force can be effectively absorbed and the rotating bucket can be reduced, thereby effectively reducing the occurrence of traffic possibility of accident.

Highway protective rolling guardrail is made of EVA and polyurethane composite material. This high-strength EVA and polyurethane material itself has the advantages of elasticity, impact resistance and wear resistance. It can prevent the rotating barrel from being crushed when it is impacted, effectively protecting the guardrail and passengers. In addition to good anti-collision and wear resistance, it also has the advantages of chemical corrosion resistance, UV aging resistance, weather resistance, etc. It is not easy to break, has a beautiful appearance, and is not easy to fade. Under outdoor natural conditions, the service life is at least ten years.
