Remote Control Removes Operator

September 28, 2010

ROC D7 CElectronic controls in Atlas Copco's ROC D7 C offer radio-remote control that allows the operator to stand safely aside while putting the machine to work on unstable ground. An automatic system adds rods to the drill string, so the operator can set hole depth and automatic feed alignment, initiate drilling, and the ROC D7 C will finish the hole on its own. The company says its machine can improve rig utilization 10 to 15 percent by continuing drilling during breaks and between shifts. The Rig Control System senses variations in the rock and adjusts drilling functions for smooth, accurate drilling. It is intended to drill 2½- to 4½-inch blast holes. Estimated list price: $375,000.
