Minnich A-3SCW/A-4SCW/A-5SCW on-slab self-propelled wireless units increase drilling efficiency, accuracy and safety. Wireless remote control technology enables operators to drill up to five holes at once and drive down the slab to drill the next set of holes — all while standing in the grade away from the equipment. From this clear vantage point, operators can drill faster and more accurately while avoiding dust, debris and obstacles. Power crab steering further boosts efficiency by letting operators drive down the slab without raising and lowering the drill bed.
