Worldwide Leader in Forging, Tunneling & Drilling


Main excavation method used in the most varied applications of civil engineering, with different techniques and not classified in series.

Tunnel Boring Machines (TBMs), just like the tunnels they create, develop in length and are characterized by their boring heads, onto which specific cutting tools for the various soils and environmental conditions are mounted.

The history of the Palmieri Group begins with the production of cutters and grows, thanks to the experience gained in the most diverse operating sites all over the world, by eventually getting to the design and manufacturing of the entire boring head, along with segment erection systems and rolling stock complete with wheels and axles.
