Qingdao Taicheng Transportation Facilities Co., Ltd
The first manufacturer of exporting new type roller barriers in China
Qingdao Taicheng Transportation Facilities Co., Ltd. is a technological innovation enterprise invested by Henger Group. Its headquarters is located in Jinkou Industrial Park, Qingdao. Taicheng Transportation has an innovative scientific research team, advanced manufacturing technology, first-class production facilities, and perfect testing methods. , reliable product quality, enthusiastic after-sales service, devoted to the great cause of improving China's road safety.
The impact-resistant and energy-absorbing rotating guardrail independently developed and designed by Taicheng Transportation has broken the technological monopoly of Korean and American countries and filled the market gap of China's rotating guardrail. The product has more than 20 national patents, and has successfully passed the collision test of small cars (family 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 series of rotating anti-collision barriers have been widely used in South Korea, Japan, the United States, the United Arab Emirates and other countries. The accident rate, economic loss rate and accident fatality rate of the installed road section have been reduced by more than 95%, which has greatly protected the lives of pedestrians. Property safety provides a reliable guarantee and strong shield for road safety. It is believed that in the near future, the new type of rotating anti-collision guardrail will be popularized on China's highways and accident-prone sections, introducing innovative protection design for China's road environment, bringing leap-forward protection effects for road safety, and becoming a life project for the benefit of future generations. .
The company will always adhere to the corporate tenet of "not forgetting the original intention, people-oriented, and technological innovation", to build a first-class transportation facility enterprise with international competitiveness, to provide the society with high-quality new rotating anti-collision guardrails, and to protect the road safety of the country and the world. convoy.
product description
Rotary guardrail adopts the mode of "one column and four hurdles". By strengthening the performance and installation of the pillars and guardrails, it can effectively prevent cars from crossing the guardrail and driving out of the driving lane.A revolving structure is used to support the elastic and anti-collision and wear-resistant rotating barrel on the column, so that the rotating barrel can rotate freely on the column. Through the free rotation of the revolving barrel, the impact force perpendicular to the guardrail direction is decomposed into the direction parallel to the guardrail, which is effectively absorbed and reduced by the revolving barrel, thus effectively reducing the intersection. The consequences of accidents.
Anti-impact rotary fence is a revolution on high-speed fence.At present, the product has won 22 patents for invention, and is widely used in Korea, Japan, the United States and other countries. The mortality rate of traffic accidents in the use area has been reduced by more than 90%.The product has passed the crash test of small cars and large trucks in the Ministry of Communications Highway Test Site and achieved success. The test results have reached the technical standards of SB and SBm grade guardrails.It can be believed that in the near future, "Rotary Barrel Guardrail" will become a unique scenic line on expressways and ordinary roads in China. It will also change the history of guardrail for 50 years, bring a new concept of traffic protection, create a new road environment, and become a life engineering for the benefit of future generations.
PRODUCT MAP
Name: New Rotary Collision Guardrail for Highway
Anti-collision barrel material: polyurethane EVA
Fence Material: Q235 Hot-dip Galvanizing
Product color: Bright and bright color, according to need can be made into various colors, such as yellow, orange, red and white.
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.

Production materials
The impact-resistant and energy-absorbing rotating anti-collision barrel is made of high-tech polymer composite material—polyurethane, which is integrally formed at one time. Polyurethane material has the high strength of polyethylene material and the high elasticity of rubber material, so the barrel itself has the characteristics of high elasticity and anti-collision and wear resistance, which can avoid being smashed when impacted, and at the same time effectively protect the guardrail and passengers. to protect.
The rotating anti-collision bucket also has a strong recovery ability, which can quickly restore the original shape and performance in the case of severe impact, which can save road maintenance costs. In addition to good anti-collision and wear-resistant performance, the rotating anti-collision bucket also has many advantages such as corrosion resistance, anti-aging, weather resistance, not easy to break, beautiful appearance, not easy to fade, and many other advantages. Under natural outdoor conditions, the service life can reach ten years or more.
Product application
The appearance color of the rotating anti-collision barrel can be customized into various warning colors, such as yellow, orange, orange, red, green, etc. The high brightness reflection effect makes the anti-collision barrel maintain high recognition and warning degree in bad weather conditions such as night and rainy days, catch the driver's eye, attract the driver's attention, and reduce the accident rate. It is especially suitable for installation in accident-prone areas such as tunnel entrances, central isolation belts, rapid turning areas, complex intersections, etc. Because of its good anti-collision performance, it can also be used as various power facilities, parking lot columns, large shelf corners and other objects. defensive equipment.
Installation examples on different road sections
PRODUCT COMPOSITION AND SETTINGS
Rotary anti-collision guardrail is composed of rotating barrel, beam, column, reflecting strip, casing, cyclone and connecting parts.
Minimum Setting Length of Rotary Collision Guardrail
