    It's a Robbins.
    City of Dallas unveils the largest hard rock TBM ever to bore in the United States.

    The 11.6 m (38.1 ft) diameter #Robbins Main Beam TBM will excavate the 8 km (5 mile) Mill Creek Drainage Relief tunnel, and its size is not its only distinction. The adaptable machine will change size partway through the bore, to a more compact 9.9 m (32.5 ft).

      In this country, we have The Robbins Company which has virtually invented the TBM tunneling. I don't know why we have to import TBM from Germany and Japan for our projects? What was the last time Germans and Japanese imported a Robbins?
