LTBM Equipment Machining

The Tunnel boring machine, otherwise known as TBM, is a machine for completely automated excavation and lining of tunnels. These machines are used for the construction of railroad, highway, subway, hydroelectric, and forced conduit tunnel excavation.

Galbiati Group works with major tunnel boring machine manufacturers not only in terms of the machining, but also to manufacture the helical drives that control the rotating excavation head of the TBM.

Galbiati realized main bearings (cutterhead supports) for a tunnel boring machine.
