DONGFENG Highway guardrail cleaning truck

Dongfeng Highway Guardrail Cleaning Truck with Anti-Collision Buffer – High-Efficiency, Safe, and Intelligent Road Maintenance Solution

This advanced Dongfeng highway guardrail cleaning vehicle is engineered for superior performance in road maintenance operations. Designed specifically for national highways and urban expressways, it integrates powerful cleaning capabilities with a robust anti-collision buffer system to ensure operator safety and equipment longevity. With a total mass of 16,000 kg and a spacious 12 m³ water tank, this specialized truck delivers consistent, high-quality results across diverse environments—from routine cleaning to emergency decontamination tasks.

Key features include a dual-brush cleaning mechanism that maintains optimal distance from guardrails using intelligent automatic control systems, ensuring thorough coverage without damaging protective coatings. The forward spray reaches up to 20 meters, while the rear-mounted anti-aircraft gun offers 360-degree rotation and can reach heights of 35 meters—ideal for clearing debris from elevated barriers. Powered by a reliable diesel engine (170 hp, Euro VI compliant), it operates efficiently at speeds between 3–20 km/h, making it suitable for both slow-paced precision work and faster route maintenance. Its carbon steel tank (WISCO-grade, 5mm thickness) resists corrosion and withstands heavy-duty use, while the vertical suction pump allows for deep-water intake up to 6 meters—enhancing versatility in remote or low-access areas.

The integrated anti-collision buffer device significantly improves operational safety. When unexpected impacts occur—such as rear-end collisions on busy highways—the system absorbs and dissipates kinetic energy through specialized foam materials and hydraulic dampeners, minimizing damage to both the vehicle and surrounding infrastructure. This not only protects critical components like brushes and high-pressure nozzles but also reduces downtime and repair costs. Additionally, some models feature an early warning sensor that alerts drivers when following vehicles approach too quickly, further enhancing situational awareness during night shifts or adverse weather conditions.

Designed for professional municipal departments, highway authorities, and private contractors, this multi-functional cleaning truck supports a wide range of applications: fence washing, dust suppression, fire protection interface integration, and even snow removal in colder climates. It excels in environments where road safety, efficiency, and environmental compliance are paramount—such as toll roads, intercity corridors, and construction zones. Whether used for daily upkeep or large-scale infrastructure projects, its combination of smart automation, durable engineering, and collision mitigation makes it a future-proof investment in sustainable road care.

Users consistently report improved productivity due to reduced stress from potential accidents, increased brush life thanks to impact absorption, and better cleaning outcomes thanks to precise distance control. Many operators appreciate how the unit’s modular design allows customization based on terrain type—whether straight sections, curves, or complex barrier geometries.

Common questions often revolve around maintenance intervals, water consumption rates, and compatibility with different types of guardrail surfaces. On average, each ton of water cleans 5–8 kilometers of road barrier, demonstrating exceptional resource efficiency. Routine servicing includes checking the hydraulic system, inspecting bristle wear, and verifying the integrity of the crash-absorbing structure—tasks easily performed by trained technicians familiar with commercial vehicle mechanics.
