Yellow Aluminum Highway Impact Attenuator Retractable
Portable retractable vehicle security barriers designed for highway safety applications. This large portable highway crash attenuator provides comprehensive protection for road maintenance operations.
Installed at the rear of road maintenance vehicles, this product features an electrostatically sprayed yellow exterior with red and white warning strips and bright LED arrows for optimal driver visibility. When impacted, the internal specialized aluminum structure absorbs significant collision energy through its unique shock absorption design, minimizing accident damage and protecting both personnel and vehicles. Minor deformations can be easily repaired by replacing the internal absorbent material.
Despite its robust construction, the device features a practical design with bottom-mounted wheels for easy mobility. When fixed to the rear of construction vehicles, it can be conveniently transported. The integrated LED directional arrows can be switched in any direction and provide crucial visibility warnings to following drivers during low visibility conditions. The arrow board section can be raised and lowered, allowing for compact storage when not in use.

Frequently Asked Questions
What is this product?
This is a portable safety cushioning device installed at the rear of construction vehicles (such as road maintenance trucks). It is primarily used to warn following vehicles, absorb collision energy, and protect the forward work zone.
What are its core functions?
Warning & Guidance: LED arrow board, flashing light, reflective strips.
Impact Absorption: Patented aluminum structure absorbs impact force, reducing accident damage.
Easy Mobility: Wheeled design allows for high-speed towing behind vehicles (up to 70 km/h).
Is the arrow board adjustable?
Yes. The LED arrow board can be manually raised and lowered, and the arrow direction can be switched. It can be retracted to save space when not in use.
What if it gets damaged in a collision?
If the deformation is not severe, simply replacing the internal energy-absorbing material is sufficient for repair. The entire unit does not need to be replaced, saving significant costs.
Is installation complicated?
No. It is secured to the vehicle's rear using screws, requiring no specialized tools or complex installation procedures.
Procurement Key Points
- Confirm Dimensions and Interface
Product dimensions are customizable. Before purchasing, measure the installation space at the vehicle's rear and provide drawings or specific dimension requirements.
- Focus on the Patented Absorption Material
The core safety component is the patented energy-absorbing aluminum structure (Patent No.: ZL 2006 1 0057817.8). Confirm the use of genuine OEM materials during procurement.
- Check Warning Function Completeness
During inspection, test: LED arrow board raising/lowering and direction switching, flashing light, buzzer for proper operation, and ensure reflective sheeting is intact.
- Inquire About Maintenance and Parts
Clarify the replacement process, part pricing, and supply lead time for the energy-absorbing material in advance to facilitate future maintenance.
- Note the Speed Limit for Use
Towing speed must not exceed 70 km/h. Operators must be informed to adhere to this safety limit.
- Confirm Packaging and Transportation
The product is heavy (129 kg). Confirm adequate anti-impact packaging and arrange for proper equipment (such as forklifts) for unloading and handling.
