Revolutionizing the underground construction industry, the Barbco Tribor is a hybrid of three types of machinery: an auger boring machine, a guided boring machine and a horizontal directional drill. Tribor is available in three models — Tribor30, Tribor36 and the Tribor48. Each capable of delivering torque equivalent to their respective conventional auger boring machine’s in third gear. Tribor accommodates just about any down hole steering system no matter if it’s a conventional HDD transmitter housing, mud motor, air hammer or camera assist target housing. Combined with a robust mud circuit, we’ve developed the most versatile system in the industry.
