Anti-shock energy-absorbing highway roller barriers (new rotary anti-collision guardrail)
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.
The new rotary anti-collision guardrail series products have been
widely used in Korea ,Japan ,the United States ,the United Arab
Emirates and other countries . The accident rate , economic loss
rate and accident mortality rate of the installation sections have
been reduced by more than 95% ,which greatly protects the lives of
pedestrians . And the new rotary anti-collision guardrai provides a
reliable guarantee and a strong shield for road safety. I believe
that in the near future, the new rotary anti-collision guardrail
will surely popularize the highways and
accidents in China, introduce innovative protection design for the
Chinese road environment, bring leaps and bounds to road safety,
and become a life project for the benefit of future generations .
Our company always adhere to the corporate tenet of “not forgetting
the initial heart ,people-oriented , technological innovation ”, to
create a first class transportation facilities enterprise with
international competitiveness , we would like to provide
high-quality new rotary anti-collision guardrail to protect road
safety for the whole country and the world.
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
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.
