Tunnel Boring Machines (TBMs) (click link for product specifications) are used to install 48 – 93-in. (1,219 – 2,362 mm) OD jacking pipe. The Series II TBM family consists of eight TBM models with common ease of operating controls. The Series II TBM has a sealed steering joint that allows for bidirectional, full articulation at the face of the bore. Its drive system uses two-speed drive motors which operate in either low-speed/high-torque or high-speed/low-torque modes. This functionality allows operators to precisely tailor cutting speeds and torque in varying geology. TBMs come standard with three bi-directional cutter heads: sand, single dirt carbide bar and quad dirt carbide bar.
