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
Working principle:
The rotating anti-collision guardrail combines the advantages of traditional guardrails and new impact-resistant energy-absorbing drums, and realizes the protection method of "one column and four columns". The rotating anti-collision guardrail improves the installation method by strengthening the performance of traditional columns and guardrails. The rotating bucket can rotate freely on the column. When an accident occurs, the free rotation of multiple groups of anti-collision rotating buckets can effectively decompose the impact force of the car, so that the impact energy perpendicular to the direction of the guardrail can be converted into rotational energy parallel to the direction of the anti-collision rotating bucket. , The combination of this rotational energy and the elastic energy of the rotating barrel can pull the accident vehicle to maintain the normal driving direction and speed, while avoiding the "head-to-head" situation of the vehicle and the traditional guardrail in previous traffic accidents, it can prevent the car from passing through the guardrail and driving out. Drive lanes, thereby effectively reducing the serious consequences of traffic accidents, and protecting the personal safety of drivers and passengers to a great extent.
1. Adopt high-quality original material.
Roller EVA material with elastic characteristics is used as raw material, which can slow down the lateral impact process of the out-of-control vehicle. Moreover, the rotating barrel can rotate around the column under a certain impact, driving the out-of-control vehicle to return to the correct driving direction.
2. High quality steel support.
Using Q235 steel, multiple thick steel fixed, durable, strong protection ability.
3. Strong of lower solid frame.
The round post could buried deep, structural strengthening, can effectively block the front or side impact.
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 |
1. Column: It is driven into the roadbed and is the main force-bearing component.
2. Beam: It is used to connect the columns and fix the rotating barrel.
3. Rotary 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: It is installed on the inner wall of the rotating barrel and is a touch component with rotating function. 5) Gyratory 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: connecting the beam and the column to fix the beam.
8. Pad buckle: Lined with the beam and connected to the U-shaped frame.
9. Hoop: connecting beams and columns, used to fix beams, suitable for specific types.
10. Reflective strips.•It is a reflective film, which is pasted on the rotating barrel and plays an inductive role.

Working principle of rotating guardrail
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.

Wear resistance is higher than 200% Wear resistance is higher than 200% to other anti-collision barrel materials in the market . Due to its unique production process and process, Taicheng Rotary Anti-collision Barrel
has 3mm thick hard polyurethane protective layer in the outer layer of the barrel. Its tensile strength and bearing capacity are 2-3 times that of other anti-collision barrels in the market.
Acid and alkali resistance, high temperature resistance and low temperature resistance, radiation resistance, impact resistance, aging resistance, high flame retardancy. The outer protective layer makes the barrel
itself have a high flame retardant rate, preventing secondary fires in traffic accidents from burning the rotating barrels . Other similar materials anti-collision barrels are not flame retardant, they are burned in case of
fire and have a strong open flame. It can prevent the rotating cylinder from being crushed when it is hit, and effectively protect the guardrail and passengers. It is not easy to break, and has a beautiful appearance
and does not fade easily. Under natural outdoor conditions, the service life is at least ten years.
The new rotary anti-collision guardrail series adopts modular design, the whole installation is simple and quick, no need for professional guidance, the installation is safe and pollution-free, and the installation cost is low.
The energy-absorbing anti-collision barrel has strong wear resistance and impact resistance. The rotary anti-collision guardrail is designed firmly. It is not necessary to replace the guardrail for ordinary traffic accidents,
can save a lot of after-sales.
