At its pre-ConExpo-Con/Agg media event, Caterpillar showcased the new MD5150C Track Drill, the first of its C Series drills, designed to deliver top-of-class power and high airflow for fast, efficient drilling of 4- to 6-inch holes.

“This machine is more productive and lower cost to operate than the 5120 that it replaces,” says Jim Peterson, product manager, noting that 95 percent of the anticipated use of the drill will be for blasthole drilling. To make exploratory drilling and bench development easier and safer, the two tracks have 11-percent independent movement to navigate rough terrain.

The unit offers a choice of three different rock drills, patented carousel rod changer, ergonomic cab, and other features that boost productivity and reduce operating costs. Compared to its predecessor, the 5120, the 5150 has 18 percent more power, a compressor that can deliver 33 percent more air volume and 40 percent more air pressure, 19 percent faster tram speed, and 40 percent greater ground clearance.

To streamline maintenance, in addition to available on-site service, the unit has only half as many moving parts as competitive drills, Cat says.

“We’ve had a lot of feedback from customers,” Peterson adds. “This unit is all Cat DNA.” To simplify maintenance and ensure the unit spends more time in production mode, all of the filters, pressures and flows can be accessed from a single point in the back of the drill.

An automated lube system eliminates the need to stop the machine for manual greasing every two hours. Setup time is quick due to an innovative carousel rod changer that holds six rods and accommodates two lengths and multiple diameters of drill steel. The rod changer and feed assembly have seven patents pending.
