Roadway Use EVA Roller Cushion Crash Barrier For Highway Traffic
Safety
Roller guardrail/rolling guardrail
Safety roller, also known as roller guardrail, rolling guardrail,
roller guardrail, roller guardrail or road roller, is widely used
in sharp turns or curved roads.
A safety roller is a fixture that prevents fatal accidents for
drivers and passengers by absorbing impact energy and converting it
into rotational energy. Its design purpose is to effectively absorb
impact force, guide the vehicle back to the road direction, and
prevent major accidents on curves or sharp turns.
The safety roller, with its eye-catching color and
self-illuminating properties, effectively helps the driver to
control the vehicle correctly.
Precautions :
1. The roller guardrail can be used as the side guardrail, middle
guardrail, bridge guardrail of small bridges, channels and clear
culverts in the roadbed section.
2. The roller guardrail can be used as the upstream end guardrail
in the driving direction. Roller guardrails should be installed at
the end of the interconnecting diversion triangle. When the number
of lanes on a road section decreases, roller guardrails are
installed on the transition section. Roller guardrails should be
installed at the tunnel entrance to enhance the section transition.
3. The density of the side and middle subgrade soil should comply
with relevant standards and requirements, and concrete and other
measures should be taken to reinforce it when necessary.
4. Transition processing should be carried out between roller
guardrails and other types of guardrails.
5. The rotating drum should be yellow to indicate a warning.
6. When the roller guardrail is installed on the inside or in the
middle of the lane, the color of the reflective strips should be
yellow; when it is installed on the outside of the lane, the color
of the reflective strips should be white.
7. The roller guardrail should not be equipped with reflective
outlines.
1. Use high-quality raw materials.
The roller EVA material with elastic properties is used as the raw
material, which can slow down the lateral impact process of the
out-of-control vehicle. Moreover, the rotating drum can rotate
around the column under a certain impact force, driving the
out-of-control vehicle back to the correct driving direction.
2. High-quality steel support.
Made of Q235 steel and fixed with multiple thickened steels, it is
sturdy, durable and has strong protective capabilities.
3. The lower frame is strong.
The cylinder is buried deep and the structure is strengthened,
which can effectively block frontal or side impacts.
Advantages:
Low cost
High flexibility to install and repair
Cable tension and post space can be adjusted.
Prevent vehicles from running off the road effectively
Absorb most sudden impact energy during collision
Good looking for the usage in open scenic spots
Anti-rust, anti-corrosion and anti-aging
Qingdao Taicheng focuses on the export business of transportation
facilities and has rich experience in container packing and
crating. The guardrail panels are packed with steel wire ropes, the
columns are transported on pallets, and guardrail accessories such
as gaskets are transported in ton bags. This assembly method
ensures that the products arrive at the destination port and is
convenient for loading and unloading.
1. The guardrail packaging adopts bundling method, which is
convenient for loading and unloading. It also keeps the container
balanced and facilitates transportation.
2. The guardrail columns are packaged in a tic-tac-toe bundling
method, which is strong and easy for forklift loading and
unloading.
3. Guardrail accessories are packed in large bags or simple wooden
boxes for easy loading and unloading, and can be installed after
arrival.
