Lifeline Air Bag Retractable Truck Mounted Attenuator Anti-Collision
Advanced Rear-End Collision Protection System
The Lifeline Air Bag Anti-Collision Truck Mounted Attenuator serves as a critical safety barrier for commercial vehicles, functioning as an "air bag" for truck rears. Designed for pickup trucks, vans, semi-trailers, and various commercial vehicles, this system provides essential protection during maintenance operations, temporary parking, and construction site activities.
When vehicles require extended stationary periods, this attenuator absorbs collision impact forces, prevents rear-end collisions from escalating, and significantly reduces accident severity and potential injuries.

Core Safety Functions
- Impact Absorption: Effectively absorbs rear-end collision energy to reduce damage
- Underride Prevention: Physically prevents smaller vehicles from underriding the truck
- Passive Safety: Designed considering sedan front-end height to protect following driver's head and chest
- Mobile Warning: Conspicuous color and structure enhance rear-end visibility
- Convenient & Flexible: Retractable during travel, deployable when parked
This safety device acts as crucial retrofitted passive safety equipment, minimizing occupant injury and property damage in rear-end collisions through robust structure and scientific buffer design.
Product Advantages
Proven Design, Safe and Reliable
Based on the classic design from Japan's HANAI CO.,LTD, this market-tested system is renowned as the "Lifeline" for truck rears.
Dual Protection Mechanism
Active Protection (Warning): Conspicuous red-and-white coloring and prominent structure effectively alert following vehicles, reducing accident probability.
Passive Protection (Energy Absorption & Underride Prevention): Sturdy structure combined with aluminum alloy buffer material forcefully absorbs impact energy during collisions and physically prevents trailing vehicles from underriding.
User-friendly Retractable Design
Equipped with wheels for easy one-touch deployment/retraction. Retracts during travel without affecting ground clearance or compliance, while providing instant protection when deployed.
Robust and Durable Construction
Main structure uses high-strength channel steel and stainless steel with electrostatic spray coating for corrosion resistance and long service life.
Wide Compatibility and Customization
Compatible with various trucks weighing 2.0-4.0 tons, with customization options for dimensions and colors to meet personalized fleet requirements.
Cost-Effective Safety Investment
As crucial retrofitted safety equipment, it effectively prevents major casualty accidents and property damage, representing high-value preventive safety investment.
This Truck Mounted Attenuator integrates six major advantages: authoritative design, active warning, passive protection, ease of use, rugged durability, and flexible customization, making it a professional solution for enhancing road safety for large vehicles.
Frequently Asked Questions
Can this anti-collision barrier really prevent cars from "underriding"? What is the principle?
Yes, this is its core function. The principle is based on physical height matching and rigid blocking. Its installation height (typically matching the truck's rear ground clearance of about 100 cm) precisely covers the front end of a sedan (approximately 70-80 cm) and the driver's head position. In the event of a rear-end collision, the sturdy anti-collision barrier first makes contact with the rear vehicle's bumper or engine hood, transferring the impact force to the vehicle's frame instead of allowing the car to slide directly under the truck.
What are the practical benefits of the "retractable" and "wheeled" design?
These features greatly enhance practicality: It can be fully retracted while driving, adding no extra length to the vehicle and complying with road regulations. When extended parking is required, it can be easily pulled out and deployed without tools, quickly establishing a safety zone.
What are the advantages of using a combination of channel steel, stainless steel, and aluminum alloy?
This material combination achieves a balance of strength, corrosion resistance, and energy absorption. Channel steel provides ultra-high structural strength, stainless steel offers excellent rust resistance, and aluminum alloy effectively absorbs and disperses impact energy through controlled deformation.
Can my vehicle be equipped with this? Is the installation process complicated?
The product is suitable for various trucks and trailers with a total weight between 2.0 and 4.0 tons. Installation involves suspension-type fixing, requiring professional personnel to drill holes and secure bolts on the rear chassis frame.
Can dimensions and colors be customized?
Yes. In addition to standard specifications, we offer customization services for dimensions (tailored to vehicle width or ground clearance) and colors (corporate branding options).
Does it need to be operated frequently during daily driving?
No. It should only be deployed when the vehicle is parked in environments with potential rear-end collision risk. During normal driving, ensure it is fully retracted and locked in place.
