Ever wonder how tunnels get cleaned?

Nicknamed the "Octopus Truck," this innovative tunnel-cleaning vehicle is equipped with 8 robotic arms. Each arm is fitted with a brush and high-pressure water jets for a thorough scrub. Created by Colas, the truck is inspired by car wash systems adapted to handle tunnel maintenance. What sets this eco-friendly solution apart is its ability to clean without the use of detergents. Reducing environmental impact while maintaining effectiveness. The truck requires two people: one to drive and the other to control the arms and cleaning equipment. It efficiently removes dirt, soot, and grime from walls and ceilings, ensuring tunnels remain clean for traffic. Learn more at Colas.co.uk
