Detachable Galvanized Truck Impact Attenuator

This truck-mounted attenuator provides movable traffic safety protection for road work operations. It effectively prevents rear-end collisions and eliminates the risk of small vehicles underriding work vehicles, significantly enhancing safety for mobile road operation personnel, equipment, and both vehicles involved.

Detachable truck impact attenuator mounted on vehicle

Constructed primarily from aluminum alloy, this product features our proprietary honeycomb aluminum alloy core designed to absorb impact forces and reduce collision energy between rear-end vehicles and protected vehicles, ensuring personnel safety.

Frequently Asked Questions

What is the full name and core function of this product?

Full Name: Mobile Rear Guard Crash Cushion
Core Function: Rear safety warning and high-efficiency impact energy absorption. In the event of a rear-end collision, its internal energy-absorbing structure absorbs the impact force, preventing the colliding vehicle from under-riding the protected vehicle, thereby safeguarding personnel and property in both vehicles.

Which vehicles is it primarily suitable for?

Suitable for various specialized work vehicles operating on municipal roads, such as road maintenance trucks, sweepers, water trucks, tunnel washers, and other scenarios involving mobile or temporary work operations.

What are the standard dimensions and weight of the product? Is customization supported?

Standard Dimensions: W660mm * L650mm * H1055mm
Weight: 37KG per unit (standard configuration is a set of 2 units)
Customization: Supported based on vehicle dimensions. Color customization is also available (standard color is engineering warning yellow)

What are the key features of the product's structure, materials, and installation?

Materials: Main body uses high-strength aluminum plate, special aluminum profiles, and reinforced steel beams. The buffer core consists of a high-performance aluminum alloy energy-absorbing structure (honeycomb design)
Structure: Features a mobile design with wheels at the bottom. The top has convenient hooks for suspension mounting, requiring no tools or vehicle modification
Surface Treatment: Electrostatic spraying process for corrosion resistance and wear durability
Accessories: Comes standard with high-brightness strobe warning lights (integrated on the suspension rods). The front is covered with a large area of high-performance reflective film

How does the product achieve all-weather safety warning coverage?

Daytime: High-visibility engineering warning yellow ensures excellent visual recognition
Nighttime/Adverse Weather: High-brightness LED strobe lights on the suspension rods offer strong light penetration. Combined with the large-area reflective film on the front, they provide both active and passive warning for enhanced safety

Has the product's safety been verified?

All products undergo stringent road safety testing in Japan, complying with international road safety usage standards. They offer proven卓越 performance and guaranteed quality.

What advantages does it have over traditional buffer devices?

Lightweight & Easy to Use: Relatively light weight and equipped with wheels for easy mobility
Quick Installation: Suspension design allows for immediate use upon hanging, with no complex installation or vehicle modification required
High-Efficiency Protection: Combines active warning (strobe lights) and passive energy absorption (honeycomb structure) for comprehensive protection

How does the product absorb collision energy?

The internal unique honeycomb aluminum alloy energy-absorbing structure is designed to deform in a scientifically controlled manner upon impact, efficiently absorbing and dispersing kinetic energy to minimize damage to both the protected and colliding vehicles.

What is the standard configuration?

Provided as "a set of two" units. They are typically mounted side-by-side at the rear of the vehicle to create a wider safety protection zone.

In what scenarios is this product most suitable?

Mobile operation scenarios on municipal roads such as maintenance, cleaning, and landscaping, as well as temporary lane closures or work zones requiring enhanced rear-end collision protection.
