Fixed Type Buffer Device Back Guard HS-80W-LT Highway Crash Attenuator TMA
The fixed buffer device is installed at the rear of large vehicles to prevent rear-end collisions where vehicles could underride the truck bed, protecting both personnel and vehicle safety. This product is primarily designed for temporary and mobile road safety maintenance operations. When mounted on a vehicle parked behind construction zones, it absorbs impact energy from rear-end collisions, safeguarding workers in the operational area and minimizing vehicle damage.
The anti-collision cushion guard features a highly visible yellow color scheme with extensive red and white reflective film coverage for maximum warning effectiveness. The device includes a mounting bracket for easy installation, secured to the vehicle's rear using high-strength stainless steel bolts.
The buffer package is engineered to withstand impacts from multiple angles. During a rear-end collision, the internal honeycomb absorption material deforms to effectively dissipate impact forces.
All our products undergo rigorous Japanese road safety testing and comply with international road safety specifications.

Core Question |
Action & Purpose |
| Step 1: Define Requirements |
• Where will it be mounted? (Specific vehicle model, rear structure)
• Where will it be used? (Highway/municipal roads? Duration of operation?)
|
Purpose: Determine the required protection level, custom interface, and suitable dimensions.
|
| Step 2: Verify Credentials |
• Are there authoritative certifications? (e.g., Japanese test reports, MASH or ECE certifications)
• What brand is the reflective sheeting? (Is it engineering-grade, e.g., 3M?)
|
Purpose: Ensure the product's safety performance is reliable and durable—the foundation of a safe investment.
|
| Step 3: Focus on the Core |
• Is it a "disposable" product?
• Can it be repaired after a collision? How? Who covers the cost?
|
Purpose: Prioritize recoverable designs, as this is the decisive factor for long-term ownership costs.
|
| Step 4: Confirm Details |
• Is the mounting bracket compatible with my vehicle?
• Do the LED lights and electrical interface match?
• What is the warranty period? What does it cover?
|
Purpose: Ensure the product is ready to use upon arrival, avoid secondary modifications, and clarify after-sales rights.
|
| Step 5: Compare Value |
• Don't just look at unit price.
• Calculate the total cost of ownership: "unit price + repair costs + service life."
|
Purpose: Choose the solution with the lowest long-term total cost and the highest safety return.

Q & A
1. What is this product?
This is a TMA rear underride protection and energy-absorbing device for specialized vehicles, named the "Fixed Rear Guard," manufactured under the brand RMHs.
2. What is its main purpose?
Its core functions are "underride prevention" and "energy-absorbing cushioning." When a work vehicle equipped with it is temporarily parked behind a work zone, it effectively prevents a following car from underriding the truck bed in a rear-end collision. Its internal structure absorbs the impact energy, protecting workers in the forward work area.
3. What material is it made of? Is it heavy?
It is constructed entirely from high-quality aluminum alloy, making it both robust and lightweight, with a net product weight of 96 kg.
4. Are its dimensions fixed?
The standard dimensions are 1850mm (W) * 635mm (D) * 450mm (H), but it supports customization based on customer requirements.
5. How is it installed on a vehicle?
It uses a suspended mounting system, secured directly and firmly to the vehicle's rear chassis beams via dedicated brackets and high-strength bolts (such as stainless steel bolts).
6. Can it be seen clearly at night or in bad weather?
Yes, its warning effectiveness is excellent. In addition to the standard engineering yellow color and large-area high-intensity reflective sheeting, the top is equipped with two high-intensity LED strobe lights. Together, they form an all-weather warning system that is particularly conspicuous at night or in rainy/foggy conditions.
7. If it gets hit in a collision, is it completely scrapped?
No. This is one of its key advantages: its energy-absorbing module features shape-recovery characteristics. After a moderate-intensity collision, its protective performance can be restored through professional refurbishment, significantly reducing long-term ownership costs and breaking the "disposable" limitation of traditional products.
8. What types of vehicles is it suitable for?
It is primarily suitable for various specialized vehicles that need to park temporarily beside roadways for work, such as: road maintenance trucks, sweepers, water trucks, tunnel cleaning vehicles, and emergency rescue vehicles.
9. Is the product quality guaranteed?
Yes. All products undergo stringent road safety testing in Japan, and their performance indicators comply with international safety standards.
10. What unique designs make it user-friendly?
The product features wear-resistant rubber wheels at the base and ergonomic hand grips on both sides, enabling quick movement and positioning by a single operator, making deployment and relocation highly efficient.
