Aluminum Fixed Trailer Mounted Attenuator
The RMHs Fixed Rear Guard is a heavy-duty rear underride protection device specifically engineered for road maintenance vehicles. Its primary function is to establish a robust passive safety barrier for work crews—including maintenance, cleaning, and emergency response teams—temporarily stationed adjacent to active traffic lanes.
Utilizing a patented aluminum honeycomb energy-absorption structure, it efficiently absorbs impact energy during rear-end collisions, effectively preventing smaller vehicles from underriding the truck bed to protect lives and equipment.

What is an Aluminum Fixed Trailer Mounted Attenuator?
As a mobile anti-collision protection device, it features high-quality aluminum alloy as its core material and is specifically designed for trailer mounting. Equipped with an advanced energy-absorbing structure, it can absorb collision kinetic energy in a stepped manner when accidental vehicle impacts occur. This effectively minimizes damages to construction personnel, road equipment, and the striking vehicle, making it an essential safety solution for temporary work scenarios such as road construction and maintenance.
Why Is Aluminum Alloy Selected as the Core Material?
Aluminum alloy stands out as the optimal material choice due to its three key advantages:
- Lightweight Property: Significantly reduces device self-weight compared to traditional steel structures, simplifying trailer towing and on-site relocation while optimizing fuel efficiency.
- Superior Corrosion Resistance: Excellent adaptability to harsh outdoor environments including high humidity and salt spray, prolonging service life and reducing maintenance costs.
- High Structural Strength: Fully meets mechanical performance requirements for collision buffering, ensuring stable deformation and reliable protection during impacts.
What Is the Core Protection Mechanism?
The device integrates a multi-stage energy-absorbing system that operates scientifically upon impact: First, the outer buffer beam dissipates initial impact force, then internal energy-absorbing boxes and honeycomb aluminum structures compress and deform progressively, converting kinetic energy into structural deformation energy. This critical design avoids massive impact forces from rigid collisions, providing comprehensive protection for all parties involved.
Key Points for Daily Maintenance
To ensure optimal performance throughout its service life, the following maintenance measures are recommended:
- Conduct regular inspections to ensure all connection point bolts remain securely fastened.
- Keep the device surface clean by promptly removing dust and oil stains to prevent coating damage.
- Immediately replace damaged energy-absorbing components after collisions—deformed structural parts must not be reused.
Applicable Scenarios
This product is widely applied in various safety-critical scenarios, including but not limited to:
- Safety protection for temporary construction and maintenance zones on expressways and national highways
- Safety isolation for municipal road emergency repairs and hazard clearance sites
- Anti-collision protection for temporary operation points, such as tunnel entrances and toll station reconstruction/expansion projects
