REV Drill, a drilling rig manufacturer and equipment supplier, recently provided five REV drills and operator training to the E.W. Brown Generating Station in Mercer County, Ky., for a large solar project.

The REV Drill client won a competitive bid from Louisville Gas and Electric Company and Kentucky Utilities Company to build Kentucky’s largest photovoltaic facility — 10 megawatts of electricity occupying more than 50 acres and at least 45,000 solar panels.

The REV Drills were used to install the solar foundations. The foundations were 24-inch diameter shafts drilled into solid rock. The drills were outfitted with hydraulically controlled tilting drill masts for leveling of the drill mast to produce plumb holes on any slope or terrain encountered.

The drills were equipped with specialty LP/Cluster rock drill tooling to ensure dependability, accurate hole alignment and accelerated production. The Cluster drills were powered by external, high pressure air compressors providing 1,600 cubic feet per minute of air at 150 pounds per square inch. The Cluster drills are comprised of multiple drilling heads faced with replaceable carbide studs arranged in a 24-inch-diameter drill head, which is rotated by the drill. The drill heads fire individually, much like a jack hammer, as they rotate slowly to pulverize the rock and produce a clean drilled shaft.
