Ingersoll-Rand ECM-680 crawler drill

摘要

The ECM-680 crawler drill, Ingersoll-Rand Co.'s Drilling Solutions, is designed for drilling in various blast hole applications. The ECM-680, which can drill holes from 4 in. to 5 in. in diameter, incorporates the state-of-the-art HC-150 hydraulic drifter, in which a trapezoidal piston delivers maximum impact energy to the rock. A rebound energy recovery valve captures rebound energy and uses it to change the drifter's blow energy to match rock hardness. Higher oil flow and elevated drifter efficiency has increased the drifter horsepower by 20 percent versus the previous model.The ECM-680 is powered by an after-cooled, turbo-charged Cummins 6CTA8.3 engine. The 260 hp engine provides plenty of power to the pumps and the compressor. The engine also maintains fuel economy with an automatic throttle control that lowers engine rpm during non-drilling operations. This saves as much as 15 percent in fuel costs, according to the company.
