The MD5150 track drill, a customer-inspired design that drills holes up to 6 in. in diameter, incorporates a proven rock drill, a carousel rod changer, a new cab and other features that are designed to boost productivity and reduce operating costs. Caterpillar says the MD5150 reduces setup time thanks to the rod changer that holds six rods and accommodates multiple lengths and diameters of drill steel. Powerful dual-rod grippers and a unique gate design let the rod and gate move simultaneously. The rod changer is supported by a sturdy feed and 8-ft. boom that extends to 11 ft. for larger pattern coverage with fewer setups. Because the carousel rod changer weighs less and holds more rods than linear models, the boom extension can reach farther and drill deeper while maintaining stability. Holes can be drilled within 24 in. of the high wall, which, according to Cat, is 50 percent closer than with a linear rod changer.
