When he took the telephone call, Jim Lee was busy preparing to leave town.

He was at home in the Jackson, MS, suburb of Brandon and would leave the next day for an extended trip that would take him to auger boring job sites in New York, Wisconsin and Canada. Such a schedule is routine for Lee, a field service technician for American Augers.

InnoTek has developed special tools for tunneling boring machine (TBM) excavation that feature carbide inserts necessary for advancing the mechanical cutter.

After 35 working days of excavation, Ohio contractor Turn Key Tunneling Inc. had reason to celebrate. Their trenchless crossing beneath Interstate Highway 265 in Louisville, KY, had just been completed at an unprecedented bore length of 352 feet.

Vermeer is introducing a new laser-guided, grade-control pipe installation system that the company says has several design features not available on other on grade equipment currently available in North America.

The McLaughlin 54/60 auger delivers 950,000 pounds of forward thrust and 170,000 foot-pounds of peak torque in all soil types.

The Guided Boring method installs small diameter pipes with grade and alignment precision.

The 72-1200 NG is the next generation of horizontal auger boring machine that now offers a patented rack-and-pinion drive.
