Find out how to get it off to a good start with these options. The Atlas Copco SmartROC T35 and SmartROC T40 are the first surface drill rigs from the manufacturer to offer the option of radio remote control opera- tions by upgrading either rig with a SmartROC radio remote control kit. The T35, for hole diameters of 2 1/2 to 4 1/2 inches, and the T40, for hole diam- eters of 3 to 4 1/2 inches, drill to a maximum depth of 92 feet. The rigs are designed with a low center of gravity and a high ground clearance so they can operate safely on rough terrain. The T35 is fitted with the 27-horsepow- er COP 1840 rock drill, while the T40 comes with a 33.5-horsepower Cop 2560 rock drill. A boom reach of 25 feet in height for horizontal drilling and 18 feet forward for vertical drilling offers flexible operations. Atlas Copco | www.atlascopco.us Flanders describes its Ardvarc 4.0 as the world's first fully automated multi-pass drill rig that also features the first autonomous angle drill implementation. The machine features multi-pass and semi-pass automation, drill-hole and hole-angle accuracy, automatic drill string adding and racking, enhanced human/machine interface and data collection, and more modular hardware. It can align itself to within +/-1 degree of the design heading of the hole and automatically sets the proper mast angle, the manufacturer says. Flanders | www.flandersinc.com Caterpillar's MD5150C Track Drill, the first of the C Series drills, is designed to de- liver top-of-class power and high airflow for fast, efficient drilling of 4- to 6-inch holes. The unit offers a choice of three different rock drills, patented carousel rod changer, ergonomic cab, and other features that boost productivity and reduce operating costs. Compared to its predecessor, the drill has 18 percent more power, a compressor that can deliver 33 percent more air volume and 40 percent more air pressure, 19 percent faster tram speed, and 40 percent greater ground clearance. To streamline maintenance (in addition to available on-site service), the unit has only half as many moving parts as competitive drills. An automated lube system eliminates the need to stop the machine for manual greasing every two hours. Setup time is quick due to the carousel rod changer, which holds six rods and ac- commodates two lengths and multiple diameters of drill steel. The rod changer and feed assembly have seven patents pending. Caterpillar | www.cat.com Drilling Options Fully automated drill rig Quick setup drill
