1800×850×350mm Aluminum Crash Cushion Attenuator
The RMHs telescopic anti-collision TMA is professionally designed by HANAI CO., LTD from Japan. Its core functions are to warn rear vehicles and absorb collision impact force. It is specially adapted for the rear of various trucks such as pickups, box trucks, semi-trailers, and trailers, and is known as the "lifeline" for the rear of trucks in the industry.
From the perspective of safety scenarios, the height of the front of a small car is generally between 70-80cm, while the distance from the rear of a truck to the ground is more than 100cm. This height difference exactly corresponds to the key protective area from the head to the chest of the driver of the rear vehicle, and a rear-end collision is likely to cause fatal injuries once it occurs.

The actual vehicle collision data: when the vehicle impacts the blade type attenuator at the speed of 60km/h, the vehicle is forced to stop after taxiing for 10 meters due to the tail lifting after the collision and losing the forward power. When the rear vehicle impacts the buffer, the impact energy is absorbed and the driving speed is slowed down.

Product Questions & Answers
1. What is this? What does it do?
A "crash-proof bumper" installed at the rear of trucks and vans. Its main purpose is to prevent smaller vehicles from under-riding in a rear-end collision. It absorbs impact force to protect the lives of drivers in the following vehicle.
2. Which vehicles is it suitable for?
Primarily suitable for trucks such as pickups, box trucks, and trailers. The standard applicable vehicle weight is 2-4 tons, with customization available.
3. How does it protect the driver of a smaller car?
Truck rears are high, while car fronts are low. In a rear-end collision, the driver's head and chest area are at risk of impacting the truck's undercarriage. The beam acts as a barrier in between, absorbing the crash forces and preserving the crucial survival space.
4. Is the material durable?
The main structure is made of channel steel/stainless steel for strength. The key energy-absorbing parts use aluminum alloy. The surface features electrostatic spray coating for rust prevention and durability.
5. What are the benefits of the telescopic function?
- While driving: Retracted, out of the way.
- When parked (e.g., for maintenance, construction): Extended, forming an active protective barrier for enhanced safety.
6. How much does it weigh?
Approximately 98.3 kg (adjustable based on the vehicle), which has minimal impact on the truck's load capacity.
7. What types are available?
- With step plate: Can also be used as a step for accessing the cargo area.
- Without step plate: Pure anti-collision function.
8. Can the color be customized?
Yes. The standard color is high-visibility red/white, but custom colors are also supported.
9. Where does its core design come from?
The core design originates from Japan's HANAI CO., LTD., renowned in the industry as the "lifeline for the rear of trucks."
