Caterpillar looks to solve transportability issues with MD6200 rotary blasthole drill

The new Cat® MD6200 rotary blasthole drill has flexibility at its core; being designed as a production drill with the flexibility to do pre-split drilling. And, all of this is in a package that is Caterpillar’s most transportable rotary drill yet.

The MD6200 can perform rotary or DTH drilling in single-pass or multi-pass modes and can drill holes of 127 mm to 200 mm (5-7.87 in) in diameter.

It can drill at a negative angle up to 15°, which enables matching the slope of the highwall for pre-split drilling. This results in cleaner highwalls with less waste material going to downstream operations, according to Cat.

For traditional production drilling, the mast can tilt from vertical out to 30°, while the operator can adjust the mast angle in increments of 5° from the touch screen in the cab — with no special setup required.


The MD6200 can be transported over the road with the mast on, so can roll onto a truck when it’s time to move to another site. The new drill also has the smallest shipping envelope of any drill in its class, says Cat. In some configurations, parts outside the shipping envelope can be removed without the use of lifting tools, allowing two people to prepare it by hand for shipping.

“The drill also offers best-in-class manoeuvrability,” the company says. “Its compact working envelope and powerful undercarriage get it into position faster, reducing the time spent accessing drill patterns and moving between holes.”

A Cat 336 excavator-style undercarriage provides superior durability, tractive effort and drawbar pull, Cat adds.

The MD6200 also benefits from the integration of a Cat C18 engine, available in US EPA Tier 4 Final configuration and in US EPA Tier 2-equivalent configuration to suit regional needs.

Both high pressure and low-pressure compressor configurations offer variable volume air control, matching the compressor output to the drill tool and application needs. The system also lowers stand-by pressures while the machine is idle, further improving fuel efficiency, according to Cat.

The MD6200 also comes with Cat electronics, offering technicians the same architecture used on the company’s other machines. They also provide a platform for automated controls.

“Integrated machine protection features and interlocks help keep operators safe and the machine up and running by preventing potential failures and operating errors,” Cat says.

Product Link™ Elite allows drill health metrics and performance to be easily downloaded and tracked in real time.

The Cat cab

When it comes to the cab, the MD6200 is designed to promote operator comfort and productivity.

Ergonomic controls help the operator remain productive and efficient through the entire shift, while optional upgrades, such as a heated, ventilated seat with heavy-duty suspension and dual-pane glass, provide comfort on long shifts, according to Cat.

“Multifunction joystick controls and touchscreens are intuitive to use, and three standard cameras give the operator awareness of the work area,” Cat says.

The technology options that come with the MD6200 make it more productive and efficient. Drill Assist offers a number of automated functions, including auto level, auto retract jacks, auto raise and lower mast, and auto drill. Meanwhile, the drill depth monitoring system helps to reduce over- and under-drilling, boosting productivity and fragmentation.

The MD6200 is also ready for Cat Terrain for drilling, which uses guidance technologies to help operators drill holes in the exact location specified by the plan, resulting in smoother, safer and more efficient blasting.
