Compared to the MD5125, which the MD5150C will replace, the new drill has 18% more power, a compressor that can deliver 33% more air volume and 40% more air pressure, 19% faster tram speed and 40% greater ground clearance.
High reliability, long life and low ownership costs are said to characterise the MD5150C rock drill. Caterpillar says it is the only manufacturer offering rock drills designed to be serviced on site—to reduce downtime and control costs. Service doesn't require a clean room, and there's no need to incur freight costs to ship the rock drill to the OEM for maintenance or to keep a spare rock drill in stock to accommodate maintenance downtime.
The rock drill also features an automated lube system, which eliminates the need to stop the machine for manual greasing every two hours. Three different rock drill choices enable matching the selection to the application to achieve the highest production rate. The standard rock drill on the MD5150C is the HPR5128, which uses 51mm drill steel. Also available are the HPR6832 Rock Drill, which can use a 68mm speed rod, and the HPR6030 designed for 60mm drill steel.
The MD5150C is said to dramatically reduce setup time, thanks to its innovative carousel rod changer. The rod changer and feed assembly have seven patents pending. The system holds six rods and accommodates two lengths and multiple diameters of drill steel. Powerful dual-rod grippers and a unique gate design let the rod and gate move simultaneously, reducing cycle time. The rod changer is supported by a sturdy feed and heavy-duty 2.7m boom that extends to 3.3M 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 610mm of the highwall, which is 50% closer than with a linear rod changer.
The MD5150C delivers exceptional power and airflow for faster, more efficient drilling in hard rock applications. The heart of the power group is the CAT C11 Engine rated at 287kW at 1,800rpm. Designed for high performance and excellent fuel efficiency, the engine meets US Tier 3 and EU Stage IIIA emissions standards.
Service technicians are said to benefit from the simple component layout and convenient service access offered by the MD5150C.
