Highway Traffic Safety With Traffic Fence Barrier With Rotating Guardrail Safer Guardrail
As a longitudinal energy-absorbing structure, the rotating anti-collision wave guardrail absorbs collision energy through self-deformation or vehicle climbing, thereby changing the driving direction of the vehicle, preventing the vehicle from going out of the road or entering the opposite lane, and minimizing the impact on the occupants. hurt. It is particularly prominent when preventing vehicles from going out of the road or crossing the central partition to enter the opposite lane, preventing vehicles from drilling under the guardrail; in the event of a collision, the damage to passengers will be greatly reduced.
Anti Shock Highway Safety Roller Barrier Product Components And Specifications :
The rotary anti-collision guardrail is composed of rotating barrel, beam, column, reflective strip, casing, rotating coil and connecting piece. The exploded view is as follows:
Parts and installation:
1) Column: It is driven into the roadbed and is the main force-bearing component.
2) Crossbeam: used for the connection between the columns and fix the rotating barrel.
3) Rotating 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, rotating contact part.
5) Swivel ring: installed between the rotating barrel and the beam to balance and promote rotation.
6) Connection frame: used for connection between beams.
7) U-shaped frame: connect the beam and the column to fix the beam.
8) Cushion buckle: lined with beam and connected to U-shaped frame.
9) Hoop: connect the beam and column, used to fix the beam, suitable for specific models.
10) Reflective strip. It is a reflective film that is pasted on the rotating barrel for inducing.

New Rotary Anti-Collision Guardrail Production Qualification And Test Report
New Rotary Anti-Collision Guardrail Introduction:
The new road rotating guardrail is also called the "anti-collision bucket guardrail" or " new type highway roller barriers " . It mainly adopts the "one column and four beams " method . By strengthening the performance and installation method of the column and the fence, it effectively prevents the car 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-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
Qingdao Taicheng Transportation Facilities Co., Ltd. ( Taicheng ) is a technology based innovation enterprise invested by Henger Group . It is headquartered in Jinkou Industrial Park, Qingdao. Taicheng Transportation has an innovative research team,advanced manufacturing technology, first-class production facilities and perfect testing methods. Reliable product quality, enthusiastic after-sales service, dedicated to the great cause of improving road safety in China.
Taicheng Transportation Independents research and development, the self-designed anti-shock energy-absorbing highway roller barriers ( new rotary anti-collision guardrail )broke the technical monopoly of Korean American countries, filled the market gap of China's rotary guardrail, and was praised by the industry as “China's guardrail technology milestone ”.
The product has more than 20 national patents, successfully passed the collision test of small cars (house cars), buses and large trucks in the highway test site of the Ministry of Communications, and the test results and collision data are at the international leading level.
In addition, the rotating anti-collision barrel also has a strong recovery ability, it can quickly restore the original shape and performance under severe impact, which can save road maintenance costs . In addition to good anti-collision and anti-collision performance, the rotating anti-collision barrel also has anti-corrosion, anti-aging, weather resistance, not easy to break, beautiful appearance, not easy to fade, and many other advantages. Under outdoor natural conditions, the service life can reach more than ten years . Secondly, the appearance of the rotating barrel is bright , yellow , orange, red, green, which has a high degree of bright reflection effect, and has the function of capturing the eyeball, which can cause the driver's attention and ensure safty driving , reduce the incidence of accidents . This can make more safety when driver the night and rainy days .New anti-collision bucket guardrail is a technological innovation revolution in high-speed guardrails.
