The Tunnel Boring Machine (TBM) features crucial mechanical elements such as main bearings that support the rotating cutterhead, allowing it to excavate efficiently. Erector bearings play a pivotal role in the tunnel lining process, supporting the erector arms responsible for placing concrete segments to form the tunnel walls. Hydraulic pumps power essential functions like the movement of the cutterhead and the operation of erector arms, providing the necessary force for excavation and tunnel li
