Safety roller barrier is a fixture that prevents drivers and passengers from fatal accidents by not only absorbing shock energy but also converting shock energy into rotational energy. It is also known as a roller barrier, rolling barrier, roller type barrier, drum barrier or highway roller, and widely used on sharp carve road or bend road zone. It is designed to effectively absorb shock and lead vehicle to the road direction to prevent large accidents. The safety roller will effectively function for drivers to properly control vehicles with its notice able color and self-luminescence. The safety roller barrier is a new product. It is assembled with PU/EVA rollers and galvanized steel post and beams. The roller barrier differs from the w beam guardrail in the way it functions because It can absorb shock and lead vehicle to the road direction by roller, to prevent large accidents, whilst the W beam does not. The roller barrier is as well lighter and easier to install than w beam guardrail and it would be easier for recovery after attachment and easier to repair.

* Absorbing shock energy

* Protect the safety of drivers and passengers

* Prevent vehicles from running off the road

What is rotor guardrail?

Rotor guardrail is a protective device used around the factory or outdoor facilities to effectively prevent infrastructure or equipment from being hit by vehicles or pedestrians, causing damage to facilities and injuries to vehicles or pedestrians.Rotor guardrail is a semi-rigid guardrail with rotating cylinder as the main contact medium. The rotating cylinder can rotate under the impact force, and then drive the vehicle to complete the steering recovery, protect the safety of the driver and passengers, and prevent the vehicle from hitting the relevant equipment.The invention relates to a semi-rigid guardrail using the rotating barrel as the main contact medium. The rotating barrel can rotate under the impact force, and then drive the vehicle to complete the steering recovery, protect the safety of drivers and passengers, and prevent the vehicle from running off the road.Rolling Barrier redirects errant vehicle to the right direction by effectively absorbing the impact energy with rollers, upper and lower rails (the impact-energy is converted into rotational energy).

Key Features-1:

1.Easy installation and maintenance on curved road

2.The high-elastic synthetic resin roller is hardly damaged by impact. (Cover: PE, Core: Urethane)

3.Powder coating on rails with various colors is available upon request.

4.Minimizes damage on motorists and vehicles with rollers and dual guardrails

Roller Barrier is a new type guardrail with an anti-collision capability of 80km/h,100km/h,120km/h. It is commonly used in sharp carve road, bend road zone, tunnel entrance and highways with a better safety protection effect.

Key Features-2:

1.Rolling Barrier is best utilized in sites where vehicles are frequently exposed to accidents.

2.It will safely lead a vehicle back onto the road or completely stop it by absorbing the shock energy through spinning rollers during an accident.

3.Noticeable to drivers due to noticeable coloration and self-luminescence

4.It will minimize casualties on people and vehicles by absorbing collision shock.

What is roller anti-collision guardrail?

The roller anti-collision guardrail is composed of rotating drum, steel column, steel beam, fastener, etc. With a push of the hand, the rotating bucket in the middle can turn. The rotary drum has the characteristics of high elasticity and wear resistance, which is strong enough to avoid being broken and absorb a large amount of impact force.When the vehicle collides with the rolling guardrail, the driving direction of the vehicle is first corrected through the rotating barrel set on the guardrail to restore it to the normal running track to avoid impact rebound and cause secondary accidents; Secondly, the use of high and high-strength anti-collision protection beams set on the drum guardrail effectively prevents the vehicle from turning over the side of the road.

While avoiding the "hard" situation between the previous vehicle and the traditional guardrail, it can prevent the car from crossing the guardrail and driving out of the driving lane, thus effectively reducing the consequences of the accident and protecting the personal safety of the passengers to a great extent.Rolling barriers are barriers with rollers installed on it. The concept of rolling barrier is a structure equipped with pipes covered with roller rings. Rolling barrier activates the rolling friction when vehicle collides with it, and with rolling friction activated it reduces the severity of the accident. The roller on the barriers start to roll when it is hit by a vehicle and prevents vehicle from being suddenly stopped or overthrown, and thus reduce the severity of accident. Rolling barriers can be used as roadside barriers, median barriers, barriers on curves, etc. But it’s use can be proved more effective on horizontal curves, where there is high chance of accidents.

Components Of Rolling Barrier System: 

1.Top rail: There are two rails in rolling barrier system, which connects and supports the rollers horizontally. The upper rail is known as Top rail. It is like a guard rail, made of steel. Top rail splice is used to connect pipe with rails.

2.Bottom rail: From the two rails, the lower rail is called Bottom rail. It also connects and supports the rollers horizontally. It is like a guard rail, made of steel. Bottom rail splice is used to connect pipe with rails.

3.PVC Pipe: The rollers are installed on PVC pipes, which allows the rollers to rotate or roll freely. It is a vertical member connecting both the rails and rollers. It is made up of PVC or steel.

4.Stopper boards: It is a disc like board, which is installed between rollers and rails, at both upper and lower sides. It is used to guide objects back to road.

5.Shock absorbing roller: It is the main part of rolling barrier system. The rollers are usually made up of Urethane or recycled hard rubber. It absorbs the shock of vehicles, and convert impact energy into rotational energy.

6.LED guide lamp: A small LED guide lamp is installed on PVC pipe. It is installed on top of PVC pipe.

7.Reflective band: A reflective band is attached to the rollers to give better visibility at night. Yellow coloured reflective band/tape is used to increase visibility at night.

Roller Barrel Material:

Urethane has become the material of choice in so many of today’s performance driven applications because it exhibits extraordinary physical and mechanical properties that other materials simply can’t match. It is a type of an artificial rubber. Urethane is flexible and malleable. It possesses non-brittle property along with elasticity.Polyurethane is also used for rolling barriers. Polyurethanes are linear polymers that have a molecular backbone containing  They are unique in combining the strength of rigid plastics with the flexibility and elasticity of rubber. It also possesses non-brittle property along with elasticity.Use of recycled artificial rubber is also possible.Safety roller barrier can also called roller barrier, rolling barrier, roller type barrier, drum barrier or highway roller, and widely used on sharp carve road or bend road zone.Safety roller is a fixture that prevent drivers and passengers from fatal accidents by not only absorbing shock energy but also converting shock energy into rotational energy. It is designed to effectively absorb shock and lead vehicle running back to the road direction to prevent large accidents at bend or carve road sites.Safety roller will effectively function for drivers to properly control vehicles with its noticeable color and self-luminescence.

Key Features:

1. Roller guardrail can be used as side guardrail of subgrade section, median guardrail, and bridge guardrail of small bridge, passage and open culvert.

2. Roller guardrail can be used as the end guardrail upstream of the driving direction. The roller guardrail should be set up at the end of the interworking shunt triangle. When the number of lanes in the road section is reduced, the roller guardrail is set in the transition section. Tunnel entrance should be set up roller guardrail to strengthen section transition.

3. The compactness of subgrade soil in the side and median shall meet relevant standards and requirements, and concrete and other measures shall be taken to strengthen it if necessary.

4. Transition treatment should be carried out between drum guardrail and other types of guardrail.

5. The rotating drum should be yellow, indicating warning.

6. When the roller guardrail is set on the inside of the carriageway or the median, the color of the reflective strip should be yellow; when it is set on the outside of the carriageway, the color of the reflective strip should be white.

7. The roller guardrail should not set the reflective delineators.
