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.
