The MD5150 incorporates a proven rock drill, patented carousel rod changer, new cab and other features designed to increase productivity and reduce costs.

The rig reduces set-up time thanks to the carousel rod changer.

The changer holds six rods while accommodating multiple lengths and diameters of drill steel.

Dual-rod grippers and a unique gate design let the rod and gate move simultaneously.

This reduces cycle time.

The rod changer is supported by a sturdy feed and heavy-duty 2.4m boom that extends to 3.3m for larger pattern coverage with fewer set ups.

Because the carousel rod changer weighs less and holds more rods than linear models, the boom extension can reach further 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 MD5150 also boasts half as many moving parts as competitive rock drills.

An automated lube system helps keep the drill drilling, removing the need to stop the machine for manual greasing every two hours.

Caterpillar said the MD5150 delivered exceptional power and airflow for faster, more efficient drilling in hard rock applications.

It has a Cat C11 engine rated at 287 kilowatts at 1800 revolutions per minute.

The engine also meets US Tier 3 and EU Stage IIIA emissions standards.

It comes with an oversized, high-efficiency cooling system to help boost performance and life.

A walk-in service station provides easy access to major service points.

The drill’s cab is rollover protection system and falling object protection system-certified.

Large windows, streamlined front structures and a skylight boost visibility, as do mirrors and high-resolution cameras. There is a camera mounted on the boom.

The front window provides a secondary emergency exit.

The cab also has automatic climate control, excellent ventilation, a fully adjustable seat, ergonomic controls and switches, and sound levels of less than 80 decibels.

No word from Caterpillar as to whether the cab has a dock for an MP3 player though. After all, Van Halen is often the perfect soundtrack for a bit of hard-rock drilling.
