The CPA 295 excavator-mounted rock drill attachment drills holes from 3 to 4 inches in diameter, up to 72 feet deep. The attachment can be mounted on any excavator weighing more than 25 tons. It has the company’s HC95 hydraulic drifter. Other features include a hydraulic dust control system, rod carrousel, a radio remote control, and the Intelsense controller system. This system automatically detects and analyzes various rock layouts to best optimize the drifter striking frequency and energy, the company says.
