1800×800×1200mm RAL1023 Anti-Ram Vehicle Barriers
Modular vehicle barriers designed for convenient mobility in urban areas and work zones. This large vehicle crash cushion is specifically engineered for high-risk work zones such as expressways and freeways. In the event of large vehicle intrusion due to driver error, it absorbs impact energy in a controlled and efficient manner, forcing the vehicle to decelerate and stop, thereby creating a crucial "lifesaving buffer zone" for personnel working up to 200 meters ahead.

Setup Instructions
The vehicle barriers are suitable for restriction and construction areas with high-speed vehicles. The number of units can be configured according to actual requirements. Placing the device in front of or outside the work area effectively prevents large vehicles from entering and ensures personnel safety.
The vehicle barriers can be used with our LED arrow board for enhanced driver visibility and warning capabilities.
Constructed from aluminum parts through welding and electrostatic spraying processes. Special rubber pads are installed at the bottom for stability and friction.
Structure and Technical Highlights
Patented Energy Absorption System
- Primary Absorption Zone: Constructed from patented aluminum alloy material featuring high deformability, flame resistance, and environmental recyclability
- Base Damper Matrix: Equipped with 8 specialized shock absorbers managing impact forces from head-on collisions at angles up to 25°
- Friction Braking: Rubber base plate creates high friction with road surface, assisting in kinetic energy dissipation and preventing vehicle underride
Structural Design & Craftsmanship
- Structural Design: 2 main bodies connected in series by high-strength stainless steel connecting tubes, forming wide interception surface with exceptional rigidity
- Mechanical Principles: Utilizes lever principles and momentum transfer mechanisms to lift front wheels and direct kinetic energy downward
- Surface Finish: High-visibility engineering yellow electrostatic spraying for rust prevention and weather resistance
Modularity & Portability
- Detachable Design: Modular concept allows quick disassembly into 8 individual components
- Rapid Deployment: Requires only 2 personnel for assembly/disassembly, saving labor costs
- Easy Mobility: Equipped with rubber wheels for movement and anti-skid rubber plates for stable positioning
Core Advantages
- Proven Interception Performance: Tested by professional institutions like Japan Automobile Research Institute (JARI) with demonstrated deceleration capabilities
- Secondary Accident Prevention: Aluminum alloy construction reduces spark generation, lowering post-collision fire risk
- All-Scenario Adaptability: Suitable for various complex conditions including expressways, bridges, and tunnels

Product Knowledge Q&A
Q1: What is the main purpose of this product? How is it different from ordinary roadblocks?
This is life-saving equipment. Ordinary roadblocks (like water barriers or cones) only serve as warnings; large vehicles can easily crash through them. This crash cushion is designed to forcibly intercept an out-of-control large truck (up to 10 tons) that intrudes into the work zone, using its energy-absorbing design to bring the vehicle to a safe stop, protecting construction workers ahead.
Q2: It weighs 132kg. Is it easy to move on-site?
Rest assured. Although the main body is heavy (necessary to stop large vehicles), it is equipped with rubber wheels at the base. Two people can easily push and move it on flat ground. Once in position, the anti-skid plates on the bottom automatically grip the surface to prevent sliding.
Q3: Can it be used again after one impact?
This depends on the severity of the impact. The core energy absorption zone (patented aluminum alloy) absorbs energy through deformation. For a low-speed, minor touch, it might be minimally affected. However, after a high-speed, severe impact, the energy absorption zone will likely show significant crushing deformation. Typically, the energy-absorbing components need to be replaced to ensure safety for the next use (specifics require inspection and assessment by professionals).
Q4: Why is aluminum alloy better than steel?
There are two main advantages:
1. Better Energy Absorption: Aluminum alloy can deform in a controlled, predictable manner, absorbing energy like a "crushing soda can"; steel is very hard and can transfer impact force directly to the vehicle and occupants.
2. Safer: Aluminum alloy is less likely to produce sparks upon impact. At accident scenes involving potential fuel leaks, this significantly reduces the risk of fire or explosion.
Q5: Do you have test reports for this product?
Yes. Our core energy-absorbing material holds a patent, and the product has undergone rigorous overseas safety testing. Test data shows it can reduce the stopping distance of a 10-ton truck (traveling at 80 km/h) by nearly 5 meters, demonstrating significant interception effectiveness.
