Rotatable crash barriers for dangerous road sections
Qingdao Taicheng Transportation Facilities Co., Ltd
Company Qualification
As a manufacturer specializing in the production of new road
anti-collision guardrails,we have obtained more than 20 national
production patents, and in July 2018 we passed the SB-class
rotating guardrail real vehicle collision and obtained relevant
reports.Qingdao Taicheng Transportation Facilities Co., Ltd As the
earliest and most professional manufacturer of rotating guardrails,
we have already cooperated with the State Council and the Ministry
of Communications of many countries to reach a national-level
project installation and construction plan.Our company is the first
Chinese export-oriented new road anti-collision guardrail currently
. Ourrotating guardrails had already exported to Jordan, Brazil,
the Philippines, Indonesia and other countries, and provide a
strong guarantee for local road safety
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.
Ethylene Vinyl Acetate Copolymer Metal Beam Crash Barrier Roller
Safety Barrier Box Beam Guardrail
As a new type of guardrail, the rotating tunnel entrance guardrail
has been used in recent years. The main component of the rotating
barrel is a flexible material made of polyethylene and EVA
(ethylene vinyl acetate copolymer), which can be used as a
longitudinal energy-absorbing structure. In the process of
collision between the vehicle and the guardrail, the rotating
barrel can drive the vehicle through its own rotation, reducing the
collision angle between the vehicle and the guardrail, thus
reducing the lateral force generated in the process of impact. The
rotating guardrail turns the sliding friction between the normal
guardrail and the vehicle into a smaller rolling friction. The
rotating tunnel entrance guardrail not only reduces the
acceleration of each component of the collision vehicle, reducing
the injury to personnel and reducing the degree of vehicle
deformation, but also reduces the collision time and increases the
vehicle exit speed. In addition, it reduces the vehicle's handling
resistance in a collision, helping the driver to operate the
vehicle quickly away from the guardrail to complete the guidance.
Rotating guardrail in the collision barrel colour setting can be
customized according to the needs of red, yellow or other colours,
to form a visual impact on the driver, with excellent guidance
function.
Minimum Setting Length of Rotary Collision Guardrail
| Highway grade | Set separately(m) | Lap setting(m) |
| Highway, First Class Highway | 70 | 15 |
| Grade two highway | 48 | 10 |
| Level 3 and 4 Highways | 28 | 5 |
The rotating guardrail is mainly composed of column, swing circle,
rotating barrel, cross beam, waveform beam, reflective strip and
corresponding connecting parts. The rotating barrel is made of a
composite material of ethylene vinyl acetate copolymer (EVA) and
polyurethane, which is elastic, impact resistant and wear resistant
and can effectively prevent the rotating barrel from being
shattered upon impact. The resilience of the barrel also ensures
that it can be quickly restored to its original state after a
severe impact. The barrel chosen by Suzhou Bypass Expressway Co.,
Ltd. is orange, which has a high brightness reflection effect and
eye catching function, which can effectively improve the driver's
attention and reduce the incidence of accidents, thus ensuring the
safety of vehicles.
Features
(1) Fast opening.
The pluggable and removable structure enables 12 m (2 sections) to
be opened and pushed in 3 minutes in case of emergency, far better
than the norm of 10 m in 10 minutes.
(2) Safety upgrade.
Through rotational friction, the instantaneous impact energy is
transformed into rotational energy and friction energy, effectively
reducing the damage to the vehicle and the degree of injury to
personnel.
(3) Material saving.
The simple shape of the product greatly saves material costs, using
about 78 kg of material per linear metre, which is 50% to 80% of
the material used in similar products in the current market.
(4) Beautiful shape.
The beautiful shape and beautiful rotating barrels have a good
sight line guidance function, which can improve the road appearance
and effectively ease the
The effect is more obvious especially at night and in rainy days.
(5) Easy to install.
The compact design of the product allows for easy installation on
site after the unit has been assembled, greatly reducing the time
spent on site and effectively reducing the risk of road-related
operations.
(6) Simple maintenance.
The rotating bucket is made of EVA composite material, which is
resistant to chemical corrosion, ageing and weathering, and is not
easily damaged by vehicle impact, and does not need to be replaced
during its service life (10 years).
