1.Why do people choose rotating guardrails?
The rotating anti-collision guardrail can reduce the lateral and
longitudinal acceleration values of the occupants during the
collision and reduce personal injuries through the rotation of the
rotating barrel, and at the same time reduce the degree of vehicle
deformation and damage.
Since the longitudinal force during the collision is rolling
friction, which is much smaller than the sliding friction between
the traditional guardrail and the out-of-control vehicle, the
rotating anti-collision guardrail can shorten the collision time
and increase the vehicle's exit speed. Moreover, the reduced
resistance during the collision will reduce the driver's control
difficulty during the collision, allowing the driver to escape from
the collision with the guardrail as soon as possible, correctly
completing the guidance process and reducing the risk of secondary
accidents.
2.Our Company
Taicheng Transportation independently developed and designed the
impact-resistant and energy-absorbing rotating guardrail, breaking
the technological monopoly of South Korea and the United States.
It fills the gap in China's rotating guardrail market and is hailed
as a "milestone in China's guardrail technology" by the industry.
As a manufacturer specializing in the production of new highway
anti-collision guardrails, we have currently obtained more than 20
national-level production patents. In July 2018, we passed the
actual vehicle collision realization of the SB-level rotating
guardrail and obtained relevant reports.
The new series of rotating anti-collision guardrail products have
been widely used in China, South Korea, Japan, the United States,
the United Arab Emirates and other countries. The accident rate,
economic loss rate and accident mortality rate of the installed
road sections have been reduced by more than 95%, protecting the
safety of pedestrians.
3.Product components
The rotating anti-collision guardrail consists of columns, rotating
barrels, U-shaped beams and connectors. All steel components are
hot-dip galvanized and anti-rust. The columns are spaced 1 meter or
0.7 meters apart. Two rotating barrels are installed on each
column.
4.Working Principle Of Rotating Guardrail
When a car hits it, it converts the collision energy into
rotational energy through rotation, maintaining the car's normal
driving direction and speed, and minimizing the incidence of
traffic accidents. Protect people's personal lives and provide a
brand-new road safety guarantee. It is especially suitable for
installation and application in accident-prone areas such as tunnel
entrances, central isolation belts, sharp turning areas, and
complex intersections. It is worth mentioning that the rotating
barrel also has strong recovery power and can immediately return to
its original shape even if it is severely impacted. In addition,
the appearance of the rotating barrel is brightly colored,
including yellow, orange, green, etc., with a high degree of light
reflection and eye-catching function, which can attract the
driver's attention and reduce the incidence of accidents.
5.Installation Location
Rotating guardrails are usually installed on highway ramps,
continuous downhill slopes and curves. When a vehicle hits a
guardrail, the rotation function of the rotating barrel and the
good resilience of the barrel body can greatly reduce the degree of
injury to the vehicle and drivers and passengers, and play a good
protective role.
In addition, there are reflective strips on the rotating barrel.
When driving at night, the outline of the route can be better
reflected through the illumination of the light, which plays a
better role in inducing the sight of the vehicle and further
ensures the safety of driving.
