We design and manufacture custom tunnel boring machines (TBMs) for pipe-jacking and liner plate applications. Our tunnel boring machines (TBM's) provide several benefits:

  • Achieve high rates of tunnel excavation and spoil removal,
  • Provide hydraulic powered steering and grade control of the pipe insertion or liner plate tunnel,
  • Allow for tunnel excavation to progress in the front of the TBM while liner plate is assembled at the rear of the TBM (for liner plate installations),
  • Custom TBM's available with removable power units.

Here at Tenbusch, we design and build custom TBM's with removable power units. For more information about employing a removable HPU for you applications please see our recent article:
