TOP HEAD DRIVE/"CFA" RIGS
For job sites with difficult subsurface drilling conditions; being hard rock, water, caving or good soils with a need for quick footage we turn to our hydraulic top head drive rigs.
With drilling torques up to 185,000 pounds of turning torque and up to 40’ high of rotary height no rock is too hard, and cased holes become more efficiently done. With a high rotary we are able to use longer augers to reach drill depths in excess of 130 feet fast and efficient in any soils. As they are hydraulically driven it minimizes breakdowns. Although these machines must drill on near level surface and do not mobilize as quick as our truck mounted drills, they make up for it in speed and efficiency in any soils type that is put in front of it. These drills are moved on our fleet of semi-tractor trucks with our 5, 7, 9 axle lowboy trailers. As we transport all of our own equipment we are able to get these machines onsite and keep you on schedule whenever and wherever needed.
