EVA Advanced Foam Sheet Highway Rotating Anti-Collision Guardrail
Qingdao Taicheng Transportation Facilities Co., Ltd, subsidiary of Qingdao Henger Group, is a technology-innovative company, based in Jinkou Industry of Qingdao City. Taicheng is devoting to improve the world road safety cause by creative R&D team, advanced production technique, high class manufacturing machines, complete testing method, reliable product quality and enthusiastic service
It is especially suitable for installation in accident-prone areas such as tunnel openings, central isolation belts, sharp turning areas, and complex intersections. Because of its good anti-collision performance, it can also be used as defensive equipment various power facilities, parking lot columns, large shelf angles and other objects.
Features of Safety Roller Barrier
1. Reduce speed by stopper board
2. Guide reflective leads a driver to drive safely
3. Recyclable material (eco-friendly)
4. Help a vehicle turn back to the road by its spinning when the car crashed the rollers laterally
5. Minimize fatal damage of people and vehicles by absorbing collision shock
6. Reduce costs in repairing and maintenance due to Roller’s resilience.
7. Stopper boards help prevent larger accidents by slowing down Roller’s spin
8. Can be used for many years, less cost.
The new type of highway rotating guardrail mainly adopts the method of "one column and four beams". By enhancing the performance and installation methods of the columns and fences, it is possible to effectively prevent cars from crossing the fence and driving out of the driving lane. On the other hand, the new anti-collision bucket guardrail has a built-in anti-collision energy-absorbing rotating anti-collision bucket, and a flexible bucket with anti-collision function
Qingdao Taicheng Transportation Equipment Co., Ltd. installs the energy absorber on the column so that the rotating drum can rotate freely on the column. Through the free rotation of the rotating bucket, the impact force of the car is decomposed, and the impact force perpendicular to the direction of the guardrail is decomposed into a direction parallel to the guardrail, thereby effectively absorbing and reducing the impact force. The rotating bucket effectively reduces the possibility of traffic accidents.
Applications of the Safety Roller Barriers
Concrete barriers and conventional metal guardrail system are effective, but cause major damage to the impacting vehicle and the guardrail itself. Now a new type barrier system called energy-absorption roller barrier system, invented by Qingdao Taicheng Transportation Facilities Co., Ltd that specializes in highway safe guardrail systems for years in China, rises in reponse to bringing innovation technology to road safety, reducing death rate in traffic accident higher than 90% compared to traditional guardrails.
On the other hand, the new anti-collision bucket guardrail has a built-in anti-impact energy-absorbing rotary anti-collision barrel, and the flexible barrel with anti-collision and energy absorption is mounted on the column, so that the rotating barrel can rotate freely on the column. The free rotation of the sets of anti-collision rotating rollers effectively decomposes the impact force of the car when the accident occurs, so that the impact energy perpendicular to the direction of the guardrail is converted into rotational energy parallel to the direction . The rotation energy can be combined with the elastic energy of the rotating barriers itself to keep the accident vehicle to maintain the normal traveling direction and speed. And it effectively mitigate the serious consequences of traffic accidents and greatly protect the personal safety of the passengers.
Structure of Qingdao Taicheng Safety Roller
How safety roller barrier works?
1. The rotating barrel 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 rotating guardrail
|When the vertical direction is pressurized until the outer diameter deformation amount is 40% of the original outer diameter, the load is immediately released, and the sample is not broken or delaminated.
Drop hammer impact test
|At a temperature of 0 ° C and a height of 1 m, the hammer was impacted 10 times with a 1 kg weight, and no cracking occurred for more than 9 times.
For the new rotating bucket guardrail, our capacity is 12-15km per month , which can meet the requirements of all urgent orders
