"Track-Jet" Hydrodemolition Machine

TRACK JET is a cutting-edge machine designed and built by Laurini Officine Meccaniche for hydrodemolition and surface removal inside tunnels. Engineered to perform with precision, reliability, and safety, TRACK JET represents a new benchmark in the field of automated tunnel restoration.

Specifically developed to remove the superficial concrete layers of tunnel linings, TRACK JET employs one or more high-pressure water jet nozzles mounted on a telescopic boom capable of covering a working arc of 220°. Its fully remote-controlled operation allows a single operator to manage all functions safely from the ground, ensuring maximum control and visibility while minimizing exposure to debris and noise.

Thanks to its electric drive system and hydraulic transmission, TRACK JET operates efficiently and silently within enclosed environments, maintaining excellent maneuverability even in confined tunnel sections. The hydraulically operated tracks provide exceptional traction and stability, allowing the machine to operate on variable surfaces and gradients.

Equipped with a robust structural frame and precision-engineered components, TRACK JET combines power with technological sophistication. It includes high-performance electric motors, a Danfoss hydraulic system, and a Scanreco remote-control unit, ensuring reliability and user-friendly operation. The system’s modular configuration allows for rapid setup, easy maintenance, and consistent performance in demanding underground conditions.
