With the growing demand for highway tunnel maintenance in Italy and abroad, Laurini has developed and patented advanced solutions for the scarifying of tunnel vaults using milling machines.
These technologies enable fast and efficient removal of the superficial cement layer across the entire arch and full length of the vault before restoring the lining, significantly reducing time, costs, and disruptions to highway traffic.
Jocker: Patented Tunnel Milling Machine
At the heart of Laurini’s offering is Jocker, a patented milling machine specifically designed for the scarifying and superficial demolition of tunnel vaults. It performs a single automated pass with a central telescopic arm system, ensuring high productivity, reduced operation times, and greater safety for the operator. Thanks to its powerful motorization (approx. 440 HP, oil flow 400 l/min, operating radius between 4.2 and 6.6 m), hydraulically stabilized base, and remote control capability, Jocker offers precision, ease of use even for less experienced operators, and transportability without requiring special permits.
Telescopic Milling Head for Excavators
Laurini also offers a full-section milling head mounted on a telescopic arm installed on a 360° rotating turret, ideal for milling inclined or overhead surfaces of tunnel vaults. It enables operations even in confined spaces within tunnels. This equipment, developed by Laurini, is suitable for 25–30 t excavators and can be quickly disassembled to revert to digging configuration.
