The ROC D7 C, a computerized surface crawler, drills straight holes quickly and accurately. It features a system that adds rods into the drill string automatically, increasing production 10 to 15 percent, the company says. Operators can set the hole depth and automatic feed alignment and initiate drilling. The drill takes over and finishes the hole on its own. ROC Manager software monitors and optimizes the drilling operation.
