B51
The B51 is the next iteration of classic Mobile Drill power and versatility – it has an available 9,876 ft-lbs torque, can be track or truck mounted, making it ideal for the 100-125 ft hollow-stem auger market. A small footprint mechanical drive unit, perfect for the geotechnical market. The heart of the B51 is the power shift transmission – this gives the operator options to shift gears and even direction without stopping rotation. This feature gives the operator a new level of control of the drill string when augering in stiff/sticky clays, making for faster and safer production in the toughest conditions.
