Warning And Absorbing Impact Force 2.0~4.0ton Truck Mounted Attenuator
A TMA truck is designed to save lives in the work zone. Since the wide use of the TMA, roadwork companies have significantly prevented crash severities, reduced the number of fatalities and injuries of roadworkers and motorists. our attenuators are tested to meet all work zone safety requirements, are intended to absorb the impact of a high (or low) speed crash, decrease damage made to the vehicle, and save workers’ lives.
The barrier is retractable. When in use, it can be expanded, with warning and anti-collision function. When not in use, it can be shrunk, does not occupy space, and also has good warning performance. The bumpers can be customized to the size of the vehicle and bolted to the rear of the vehicle.

The barrier is mainly use channel steel, stainless steel and other materials to achieve a strong and durable effect. Installing it on the rear bumper of the vehicle is equivalent to adding an airbag at the rear of the vehicle. The product is retractable. When the vehicle is overhauled, temporarily parked, when the construction is parked, any situation that requires a long time to park, just unfold the product. In the event of a rear-end collision with the car from the rear, the product uses its own unique design to reduce the impact generated during the collision, prevent the rear-end collision of the vehicle into the bottom of the vehicle in front, and reduce the burden on the passengers and passengers from the rear. The car's injury.
Advantages Compared to Traditional Designs
The core advantage of this telescopic crash barrier lies in its dual innovation in safety and functionality compared to traditional "rigid" steel bumpers. For a clear comparison, the key differences are summarized below:
| Comparison Aspect |
RMHs Telescopic Crash Barrier (New Type) |
Traditional Steel Bumper / No Protection (Traditional) |
| Core Principle |
"Intelligent Energy Absorption": Utilizes a patented honeycomb structure combined with a telescopic design to actively absorb and dissipate collision energy through deformation. |
"Rigid Resistance": Relies on material hardness to withstand impact, transferring energy directly to the vehicle body and easily causing secondary damage. |
| Safety Effect |
Dual Protection:
1. Underride Prevention: Rigid barrier prevents smaller vehicles from sliding underneath.
2. Cushioning & Energy Absorption: Reduces damage risk to both vehicles and injury risk to occupants. |
Single/Limited Protection:
• Only provides a rigid barrier.
• Direct transfer of impact force may exacerbate damage. |
| Functional Design |
Versatile & Practical:
• Telescopic: Retracts when not in use, reducing drag and parking space needed.
• With Step: Integrates a practical step for easy access to the cargo area. |
Single Function:
• Fixed installation, always protruding, increases drag and parking inconvenience.
• No additional practical features. |
| Proactive Warning |
Active Alert: Equipped with high-intensity 3M reflective sheeting that actively reflects light at night and in poor weather, warning following vehicles. |
Passive Visibility: Relies on standard vehicle reflectors, offering limited warning effect. |
