Terex Reedrill's R20T is claimed to be the first track drill to provide 360-degree rotational capability, significantly improving its access and positioning capability when working in difficult areas. In addition, the ability to rotate completely on its undercarriage and safely tram down a steep embankment adds to the drill's safety and productivity. Nicknamed the ìTexas Twister,î the R20T is a self-contained, hydraulic unit mounted on a Caterpillar 312 excavator undercarriage. It is fitted with Reedrill's HPR45 hydraulic rock drill, which is capable of sinking blastholes from 2Ω to 3Ω inches in diameter. The HPR45 is mounted on a newly designed cylinder/cable feed system that reduces noise levels and provides for smoother operation. The R20T is equipped with the hydraulically operated SmartDrill drilling system, which features self-adjusting feed force logic designed to reduce operating costs and extend the life of consumables.
