Our Hollow Stem Auger Rigs
Hollow Stem Auger - CME 75 HT
BC2 Environmental’s CME 75 HT auger rigs may be a little smaller than their bigger siblings, but they are just as capable in power and performance! These rigs have been outfitted with the High Torque package which boosts the rotational torque to 13,000 ft lbs to handle those deeper borings. Up to 20,000 lbs pulldown and 30,000 lbs retract force, BC2’s CME-75 HT rigs are also outfitted with angle packages to drill up to 45 degrees off vertical. These rigs can sample soil using either down-hole, 140 lb split-spoon samplers or SPT auto hammers.
Hollow Stem Auger - CME 85
BC2’s Central Mining Equipment (CME) 85 drill rigs are true workhorses. With rotary torque of up to 20,000 lbs., it can turn larger diameter augers in almost any soil condition and with a 465 rpm rotational speed, it can also handle both rotary and coring jobs with ease. With 28,000 lbs. of pull-down force, the CME-85 can drill and set wells in deeper zones that many hollow-stem auger rigs cannot reach. These rigs can sample soil using either 140 lb. down hole hammer or auto hammer with split spoon, continuous, or SPT samplers. These rigs are capable of converting from hollow stem auger to mud rotary drilling when subsurface conditions change."
Hollow Stem Auger - CME 95
The Central Mining Equipment (CME) 95 drill rig is the flagship rig of BC2 Environmental’s fleet. One of the most powerful truck-mounted drill rigs available today, the mechanical rotary drive with power shift transmission produces up to 31,000 ft. lbs. of torque and rotational speed up to 497 rpm. The BC2 CME-95 rigs have the speed and power to handle auger up to 14-inch diameter auger to set wells as large as 8-inches or can be outfitted for rotary and coring applications for deeper geotechnical and lithologic applications. These rigs can sample soil using either down-hole, 140 lb. split-spoon samplers or SPT auto hammers.
