Reflective film strong performance anti impact Truck Mounted Attenuator
The blade-truck mounted attenuator is installed in the rear of the truck, known as the "lifeline" of the truck in the industry. The red and white reflective warning strip of the anti-collision beam plays a warning role. When the vehicle collides with the anti-collision beam, it can greatly reduce the impact force and protect the safety of personnel.
The height of the front end of a car is 70-80 cm, while the height of the tail of truck is more than 100 cm from the ground. This height is exactly the height of the head and chest of the car driver. Blade-Truck Mounted AttenuatorIf the truck in front is not equipped with blade truck attenuator, the driver's head is likely to be stuck on the top of the car and the seat, and the steering wheel will be pushed to the driver's chest, which is likely to cause injury and death to the driver.

If the blade-truck mounted attenuator is installed, the extension of the product will prevent the car from hitting the bottom of the truck and protect the driver.
It can serve as a good warning and protection. Therefore, in order to protect the safety of personnel and vehicles, it is necessary to install the blade-truck mounted attenuator behind the truck in the road.

Advantage Comparison
| Comparison Dimension | RMHs Retractable Anti-Collision Barrier | Vehicle Without Protective Device | Traditional Fixed/Simple Protective Bar |
|---|---|---|---|
| Core Safety Performance | Dual Protection, Comprehensive Safety 1. Active Warning: Conspicuous red and white coloring. 2. Passive Protection: High-strength structure + aluminum alloy energy absorption, effectively preventing underride, protecting occupants in the following vehicle. |
Extremely High Risk In rear-end collisions, small cars are highly likely to slide under the truck, causing A-pillar intrusion and roof crushing, resulting in fatal injuries to occupants. |
Limited Protection with Potential Secondary Damage Mostly rigid connections. While they can prevent underride, they absorb almost no energy. Impact force is directly transferred to both vehicles, potentially increasing damage and injuries. |
| Design & Convenience | Intelligent & Retractable, Flexible & Convenient • Retracted when driving: Does not increase vehicle length, complies with regulations, and does not affect maneuverability or clearance. • Deployed with one touch when parked: Quickly establishes a safety zone, easy to operate. |
No Design Features — |
Fixed, Permanently Protruding • Permanently increases vehicle length: May violate vehicle length regulations in some areas. • Affects daily operations: Inconvenient for reversing, turning, and navigating narrow spaces; prone to scraping. • Inflexible: Protective state cannot be adjusted. |
| Structure, Materials & Durability | Scientific Material Combination, Long-lasting & Durable • Main body (Channel steel + Stainless steel): Combines strength and corrosion resistance. • Aluminum alloy buffer: Scientifically absorbs energy. • Electrostatic spray coating: Corrosion-resistant, maintains appearance over time. |
Relies on Original Vehicle Bumper The original rear bumper is completely incapable of withstanding high-speed rear-end impacts. |
Single Material & Simple Process Often made of ordinary welded steel, prone to rusting; rough craftsmanship, average durability; lacks professional energy-absorption design. |
| Economy & Added Value | One-time Investment, Multiple Returns • Reduces Accident Costs: Avoids exorbitant compensation and repair expenses. • Enhances Corporate Image: Demonstrates commitment to safety. • Potential Insurance Benefits: May qualify for premium discounts. • Customizable: Can match corporate VI (Visual Identity). |
Extremely High Accident Costs A single severe underride accident can lead to huge compensation for casualties, total vehicle loss, and operational shutdown. |
Single Value, Potential for Drawbacks Offers only basic blocking function. May cause additional fines or operational inefficiencies due to illegal modifications or hindrance to operations. |

Q1: What is this product used for?
A1: Two main purposes:
Prevent Underride: Prevents cars from sliding under large trucks in rear-end collisions, protecting the car's driver.
Reduce Damage: Acts like an "airbag" to absorb impact force, minimizing damage to both vehicles.
Q2: How does it prevent underride?
A2: Its installation height (about 1 meter) is designed to block the front end of a car (about 70-80 cm tall). In a collision, it impacts the car's sturdy engine compartment instead of the fragile passenger cabin.
Q3: Does it need to be deployed all the time while driving?
A3: No. It must be fully retracted during normal driving to avoid obstructing the road and comply with regulations. Only deploy it when parked for extended periods (e.g., for roadside maintenance, loading/unloading).
Q4: Is installation complicated? Can I install it myself?
A4: It is recommended to have it installed by a professional repair shop. It needs to be securely mounted to the vehicle's rear chassis frame. Self-installation may pose safety risks.
Q5: Can my vehicle be equipped with this?
A5: It is suitable for various trucks (e.g., pickups, vans, trailers) with a total weight of 2-4 tons. Before purchasing, provide your vehicle model and rear photos so we can confirm compatibility.
Q6: Can it be customized to my requirements?
A6: Yes. Dimensions and colors can be customized, for example, to match your fleet's uniform colors.
Q7: Is it durable? Will it break easily?
A7: It is very sturdy. The main frame is made of channel steel, key parts use stainless steel to prevent rust, and it incorporates an aluminum alloy for energy absorption. The surface is finished with corrosion-resistant electrostatic coating, ensuring long-lasting durability.
Q8: Besides safety, what other benefits does it offer?
A8: Three main benefits:
Cost Savings: Prevents the most severe rear-end accidents, saving huge amounts in compensation and repair costs.
Peace of Mind: Complies with regulations and does not affect daily vehicle use.
Enhanced Image: Projects a professional and responsible safety image for your fleet.
