A crash attenuator truck is a special vehicle designed to provide safety protection for road construction operations. During operation, it is positioned directly behind construction crews to warn oncoming traffic and proactively guide vehicles, minimizing disruptions to traffic flow. In the event of a rear-end collision, it creates a buffer zone between the striking vehicle and the construction work zone ahead. The mechanical structure deforms to absorb impact energy, reducing the risk of injuries to protected workers and damage to equipment, while also safeguarding occupants inside the crashing vehicle. Crash attenuator trucks are widely deployed for construction projects on expressways, tunnels, ordinary highways and other road works.

The vehicle body undergoes high-grade electrophoretic coating or composite electroplating treatment, delivering excellent anti-corrosion and rust-proof performance to withstand all kinds of outdoor operating environments. It is fitted with a single-stage energy-absorbing collision device mainly made of thin-film aluminum honeycomb material, complemented by bent aluminum pipe structures on both sides. Upon impact, the outer bent aluminum pipes absorb crash energy through deformation. Once the energy exceeds the deformation limit of the pipes, the aluminum honeycomb buffer blocks will continuously deform to dissipate the remaining impact force.

The truck is equipped with a large electronic arrow reflective signboard that displays left-turn, right-turn and road closure signs for traffic guidance. It offers active safety navigation for passing vehicles, delivers effective protection to construction staff and onsite equipment, and protects passengers within colliding vehicles at the same time.
