Drillers looking for more versatility from a drill rig will appreciate the features that earn the compact, radio remote-controlled Atlas Copco FlexiROC T20 its ranking as best in class, the company said. The rig’s upgrades come in response to input from drillers.
Not everything has changed. Commonality of parts with Atlas Copco well proven drill rigs such as the FlexiROC T15 R and FlexiROC T30 R ensure rig reliability with maximized uptime.
However, the FlexiROC T20 upgrade employs an upgraded rig control system with next-generation electrical and hydraulic components, and comes standard with preinstalled Radio Remote Control (RRC).
The FlexiROC T20 R is equipped with the COP 1435 rock drill, which has nearly 30 percent higher impact energy and 30 percent higher rotation torque than the earlier rig model. Overall drilling performance has increased as much as 40 percent due to a combination of 18.7-hp impact power and the rig’s smooth cylinder feed action.
Additional rig enhancements include a reinforced drill steel support, redesigned hose routing with three bulkheads, a new front-facing feed holder and improved access for servicing. The rig’s BMH 2000 cylinder feed is available in three different lengths.
Atlas Copco is also launching the SmartROC D60, a Down-The-Hole (DTH) surface drill rig for most types of surface drilling applications and tough conditions.
The drill rig is robust enough and smart enough to tackle aggregate and limestone quarrying, as well as surface mining and construction drilling, the company said.
The SmartROC D60 is designed for drilling 4 5/16 to 7 in. holes and can be used in a wide variety of applications and challenging drilling conditions.
Besides muscle, it is clear that this rig has been equipped with plenty of brains enabling a high level of automation designed to result in optimum efficiency and consistent productivity, according to the company.
For example, the rig’s hole navigation (HNS) and auto positioning systems ensure that the rig will locate the exact position of each hole and then accurately collar and drill them to precisely the required depth and inclination. This gives a better fragmentation and improves both the loadability and crushability.
In addition, the robust, standard feed, carrying approximately 16-ft. tubes, features built-in sensors in the rod-handling cylinders and carousel motor, enabling more reliable rod handling and eliminating the need for inductive sensors. The rig also has Auto Rod Handling as a standard feature to automatically add and then extract the rods when the desired depth is reached.
Another major advantage is the low fuel consumption. This is achieved through intelligent control of the compressor load and engine RPM, resulting in an estimated fuel saving of up to 15 percent compared to the FlexiROC D60.
Mike Wentworth, product manager for Atlas Copco in the United States, said: “What we have in the SmartROC D60 is robustness and intelligence working together to achieve optimum performance and cost efficiency. The result is that the owner gets more holes per shift and consistently high productivity.”
The SmartROC D60 can also be used for toe-hole, dewatering hole and horizontal drilling, and, as the feed can be positioned horizontally, feed maintenance is also easier.
At worksites where bench stability may be in doubt, the SmartROC D60 can be used together with Atlas Copco’s BenchREMOTE operator station that enables it to be operated at a distance of about 120 yd.
