4WD Rig for Efficient Drilling in Tough Terrain


Atlas Copco’s ROC T15 is a small, selfpropelled four-wheel drive drill rig weighing only 2,800 kg and capable of sinking holes of 22- to 45-mm (7/8- to 1.75-in.) diameter. It is equipped with a radioremote control for tramming, drilling and boom functions, and can also be fitted with a hydraulic winch that has a variable line pull for working in extreme conditions, where it is necessary to anchor the rig or secure safe tramming. Specially designed front support legs help tramming in rough terrain. The ROC T15 has the same type of stiff folding boom and durable aluminum feed as its larger siblings in the ROC family. It has more than 18 m2 horizontal coverage area. A Deutz engine meets Tier III exhaust emission standards, and rpm can be adjusted via the radio-remote control to minimize fuel consumption. A dust collector is built-in to reduce hose damage. Three different rock drills are available on ROC T15 for various applications. Atlas Copco’s COP1019HF rock drill can handle hex 19-mm (0.75-in) integrals and the COP 1022HF can handle hex 22-mm (7/8-in.) integrals and tapered equipment. With the COP 1022HF it is also possible to do extension drilling with the help of a short hex 22-mm shank end rod which has R25 threads. COP1028 can be equipped with a Magnum SR28 shank and with the help of 3,050-mm SR28 Speedrods it is possible to drill up to 9 m when extension drilling. Magnum SR28 is a special conical thread design from Atlas Copco Secoroc with a hole range of 33- to 45- mm (1-15/16- to 1¾-in.). The use of 28- mm rods prevents deviation in the hole and gives stable drilling. The ROC T15 with COP1028 rock drill combination can be equipped with a hydraulic drill steel support as an option to allow retracting and uncoupling of the rods using the remote control.
