ISO9001 Aluminum Alloy Crash Attenuator Truck
Truck Mounted Attenuator (Stationary Type) Crash Pad For Highway Maintenance Vehicle
The Truck Mounted Attenuator (Stationary Type) is specifically designed for temporary road maintenance construction operations. Positioned behind construction areas, this TMA is engineered to protect and save lives in work zones. Our TMA meets all work zone safety requirements and is designed to absorb kinetic energy from vehicle collisions, reduce vehicle damage, and protect personnel.

Professional Protection vs Basic Isolation
This represents the fundamental difference between "Professional Protection" and "Basic Isolation."
| Feature |
RMHs "Fixed Rear Guard" |
Ordinary Traffic Barrel/Steel Barrier |
| Protection Principle |
Active Energy Absorption: Utilizes patented structure for controlled collapse to absorb impact energy. |
Passive Blocking: Primarily relies on rigid obstruction; energy cannot dissipate, easily causing rebound or penetration. |
| Testing & Certification |
Internationally Standardized Testing (e.g., Japan), with quantifiable and verifiable performance data. |
Mostly lacks standardized crash testing; protective performance is unverified. |
| Post-Collision Handling |
Repairable: Energy-absorbing module can be replaced or repaired after low to medium-speed impacts. |
Mostly Disposable: Requires complete replacement. |
| Warning Effectiveness |
Active + Passive: Reflective sheeting + active flashing lights, providing 360° warning. |
Passive Reflection Only: Relies on ambient light; poor effectiveness in rain, fog, or low visibility. |
Five Core Advantages of RMHs "Fixed Rear Guard" Crash Attenuator
1. Genuine Safety: Professional Energy Absorption, Certified and Reliable
- Utilizes a patented aluminum alloy honeycomb energy-absorbing structure that effectively absorbs and dissipates massive impact forces through controlled, scientific deformation during collisions
- The product has passed international standard safety tests (e.g., in Japan), with its protective performance rigorously verified, providing dependable safety assurance
2. High Visibility: Active Warning, All-Weather Alert
- Integrates active LED strobe lights, high-intensity reflective sheeting, and engineering yellow coating, creating a dual "active + passive" warning system
- Ensures clear visibility even in low-light conditions such as night, rain, and fog, providing advanced warning to approaching vehicles and effectively helping to prevent accidents
3. More Cost-Effective: Repairable Design, Long-Term Durability
- The core energy-absorbing module can be professionally repaired or replaced after low- to medium-speed collisions, overcoming the traditional limitation of being "disposable after a single impact"
- Made from high-quality, corrosion-resistant aluminum alloy with an anti-aging coating, it offers a long service life, significantly reducing the user's total long-term ownership and maintenance costs
4. Easy Operation: Lightweight & Flexible, Quick Deployment
- Features a lightweight design (approx. 96 kg) combined with bottom-mounted wheels and ergonomic handgrips, allowing a single operator to easily move, position, and relocate it
- Greatly improves on-site deployment efficiency, saving manpower and time
5. Strong Compatibility: Customizable, Professional Installation
- Offers flexible customization services. Dimensions, markings, and mounting solutions can be tailored based on different vehicle interfaces and operational requirements
- Comes with dedicated mounting brackets to ensure a secure and safe connection to the vehicle's rear
Frequently Asked Questions
What is this?
This is a professional crash cushion mounted on the rear of road maintenance vehicles. It absorbs collision energy during a rear-end impact through its patented honeycomb structure, preventing following vehicles from underriding.
What is the core protection principle?
It uses a patented aluminum honeycomb structure that absorbs energy through controlled scientific deformation upon impact, rather than relying on rigid resistance.
What are the main advantages?
- Safer: Internal aluminum honeycomb structure + external flame-retardant material for energy absorption and fire prevention
- More Visible: Yellow coating + reflective sheeting + LED strobe lights for all-weather warning
- More Convenient: Wheel-equipped design, movable by a single person
- More Durable: Repairable after low to medium-speed impacts, avoiding full replacement
- Customizable: Supports personalized needs like dimensions and interfaces
Do I need to buy it?
Yes, if your vehicles:
- Operate on highways or expressways
- Frequently work at night or in foggy conditions
- Require enhanced safety protection for field personnel
How to choose and purchase?
- Request the crash test report (mandatory)
- Confirm it uses a metal honeycomb structure
- Clarify the warranty and repair policy
- Verify it includes LED lights and mounting brackets
Is installation and use convenient?
- Professionally installed once onto the vehicle rear
- 96kg with wheels, easily pushed by one person
- Only requires routine cleaning for maintenance
Is it expensive? Is it worth it?
- Higher initial investment, but the repairable design leads to lower long-term ownership costs
- Provides professional-grade safety protection, safeguarding invaluable lives
In a nutshell: Professional safety protection that is more economical and reliable in the long run.
