80KM Per Hour 4.0t Traffic Mounted Attenuator
The TMA Truck Mounted Attenuator provides superior safety performance with excellent life cycle costs and quick, simple refurbishment capabilities. These devices are primarily used for protecting static worksites in high-speed environments where traffic and workers interface - such as construction zones - and as shadow vehicles for high-risk mobile operations including line marking, maintenance, rubbish collection, and barrier repairs on highways.
This advanced passive safety device integrates a high-strength structure, patented energy-absorption technology, all-weather warning capabilities, and user-friendly operation. Designed to establish a robust protective barrier behind road operation vehicles, it significantly reduces the risks of personal injury and vehicle damage in rear-end collisions.

Core Advantages Comparison
| Advantage |
RMHs "Fixed Rear Guard" |
Ordinary Traffic Barrel / Basic Device |
| Safety |
Truly energy-absorbing: Patented structure absorbs impact and prevents underride. |
Rigid barrier: Prone to causing rebound or underride, higher risk. |
| Visibility |
All-weather high visibility: Reflective sheeting + strobe lights, clear day and night, even in rain and fog. |
Daytime only: Relies mainly on reflective strips, poor effectiveness at night and in bad weather. |
| Durability |
Repairable if damaged: Can be restored and reused after moderate impact. |
Disposable after impact: Usually requires full replacement if damaged. |
| Convenience |
Easy to move: Equipped with wheels and handles, one person can deploy it easily. |
Requires carrying: Heavy, needs multiple people to move, time-consuming and laborious. |
| Total Cost |
More economical long-term: One-time investment, years of use, repairable, lower overall cost. |
Repeated expenses: Requires frequent replacement, higher long-term cumulative cost. |
RMHs Fixed Rear Guard Q&A & Procurement Guide
Quick Q&A
Q1: What is the main purpose of this product?
A1: Installed on the rear of work vehicles (like water trucks, maintenance trucks). If rear-ended, it acts like a "safety cushion" to absorb the impact force, preventing the colliding vehicle from underriding the work vehicle, thereby protecting people and vehicles on both sides.
Q2: How is it different from ordinary traffic barrels?
A2: It's a fundamental difference.
- Ordinary Traffic Barrel: Just a "hard barrier." When hit, it may tip over or break, offering limited safety.
- This Product: Has a patented internal "honeycomb" structure. Upon impact, it deforms in a controlled way (like a crushable can), "absorbing" the crash energy. Much more effective.
Q3: What if it gets damaged in a crash? Does the whole unit need replacing?
A3: No! This is a key advantage. After a moderate collision, usually only the internal energy-absorbing module needs to be sent back for replacement or repair. The outer shell can often be reused, saving significant cost. Ordinary barrels are typically disposable.
Q4: Is it visible at night and in rain?
A4: Yes. It has triple protection: ① Bright yellow color ② Large-area reflective sheeting ③ Two flashing LED lights. The active lighting ensures high visibility in rain, fog, and at night.
Q5: How heavy is it? Is installation difficult?
A5: Weighs about 96 kg. It has wheels at the bottom, so one person can pull it. Professional installation is required: it must be bolted securely to the vehicle's chassis/frame using the provided mounting kit. Once installed, it's permanent.
Quick Procurement Guide
Ask yourself:
- Do my vehicles frequently work on highways or expressways?
- Is work often done at night or in foggy conditions?
- Does my company want to minimize the risk of serious rear-end accidents?
If the answer is "YES", then professional crash protection should be considered.
When choosing a product, check these four points:
- Check its "ID": Ask the supplier for an official crash test report. Products without verified reports make unproven claims.
- Check the "Core": The heart of it must be a metal energy-absorbing structure (like aluminum honeycomb). Avoid products filled with foam or plastic.
- Check the "Lights": Active flashing LED lights should be standard, not just reflective strips.
- Ask about "After-Sales": Clarify warranty length, repair process after a crash, turnaround time, and estimated repair costs.
Calculate the Total Cost:
Don't just look at the initial purchase price. Estimate the "cost of ownership over 5 years", including:
Initial Purchase Price + Potential Repair Costs
Because this product is repairable, it's often more cost-effective in the long run.
Final Checklist Before Ordering
Ensure your contract or order clearly states:
- Model, color, dimensions.
- Inclusion of all necessary mounting brackets and hardware.
- Warranty terms.
- If customized (e.g., with a logo), require an approval drawing.
