Tunnel Buffer Bifurcation Highway Crash Attenuator Anti Collision
The highway bifurcation anti-collision buffer is an impact absorption device primarily installed in accident-prone areas such as highway bifurcations and tunnel entrances. It effectively absorbs impact forces to protect drivers and vehicles, reduce accident risks, and provide comprehensive safety protection.
The split belt anti-collision package consists of an impact absorption section and installation components. The absorption section is constructed from aluminum alloy, offering excellent shock absorption performance. It absorbs collision energy through controlled deformation. After impact, only the internal energy-absorbing material requires replacement, enabling rapid repair and significant construction cost savings. Three installation types are available: fixed guardrail, fixed high guardrail, and embedded installation to accommodate various road conditions.

|
| Maintenance Feature |
Modular design. After impact, the internal energy-absorbing core can be replaced quickly without replacing the entire unit. |
| Protection Certification |
Internal energy-absorbing components are patent-certified and have passed crash tests at corresponding speed levels. |
| Customization Options |
Dimensions, color, reflective film grade, connector adaptation, etc. (Customizable based on requirements) |
Key Notes:
• Model Selection: HSK-100 is suitable for expressways (100 km/h protection). HSK-80/60 are suitable for arterial roads and main thoroughfares.
• Foundation is Critical: For embedded installation, construction must strictly follow the drawings to ensure concrete strength and dimensional accuracy.
• Core Advantage: The specifications reflect the design philosophy of "Repairable, Highly Visible, Strong Adaptability", resulting in significantly lower lifecycle costs compared to traditional concrete barriers.
Detailed drawings or test data for specific models can be provided upon request.
Comparison vs. Ordinary Plastic Crash Barrels
| Aspect |
This Product (HSK Series) |
Ordinary Plastic Crash Barrels |
| Material Strength |
✅ Aluminum alloy structure - high strength, impact-resistant, and fire-resistant. |
❌ Plastic material is prone to cracking, aging, and has low heat resistance. |
| Protection Effectiveness |
✅ Systematic energy absorption design - effectively reduces vehicle speed and guides vehicles. |
❌ Primarily serves as a visual warning with almost no energy absorption capability. |
| Service Life |
✅ Long-lasting and durable - metal resists UV rays and weathering. |
❌ Plastic becomes brittle and fades easily, requiring frequent replacement. |
| Wind Resistance & Stability |
✅ Embedded/fixed installation - stable and wind-resistant. |
❌ Lightweight and easily displaced or knocked over by wind or impact, potentially causing secondary accidents. |
| Professional Certification |
✅ Patented + internationally tested and certified - complies with traffic safety standards. |
❌ Usually lacks professional crash certification; safety is not guaranteed. |
Frequently Asked Questions
What is this?
A road crash cushion device installed at dangerous intersections. It absorbs impact energy during collisions to reduce damage.
How to choose the model?
Based on the speed limit:
• Speed limit 60 → HSK-60
• Speed limit 80 → HSK-80
• Speed limit 100 → HSK-100
How to repair if damaged?
Just replace the internal energy-absorbing core. The outer shell usually remains intact. Repairs are quick and cost-effective.
How is it installed?
Three methods: embedded in the ground, mounted on guardrails, or fixed to high barriers.
Why is it yellow?
Most visible color, easily seen day and night, alerting drivers effectively.
Is the quality guaranteed?
Yes, with patent certificates and crash test reports, verified for safety.
What are the advantages over concrete barriers?
Cheaper maintenance, faster installation, and no flying debris upon impact, making it safer.
What should be noted when purchasing?
First, request the test report; second, verify the patent certificate; third, inquire about repair costs and lead time.
