Caterpillar and its southern Africa dealer, Barloworld Equipment, are set to present a broad range of machines, technology and support services at next week’s Mining Indaba, in Cape Town, South Africa.

The Caterpillar exhibit at Indaba, running from February 3-6, will feature digital displays of electric power generation systems, surface and underground mining equipment, and Cat MineStar™ technology capabilities – ranging from vehicle safety systems, such as operator fatigue monitoring, to production systems using teleremote, semi-autonomous and autonomous machine operation.

Caterpillar has recently introduced several new underground hard-rock mining vehicles in Africa. The new R1700 underground LHD brings the latest technology for semi-autonomous and fully autonomous operation to the region. The loader also delivers more than 30% greater fuel efficiency, 65% more lift and tilt force, and 15 t capacity – 20% more than its predecessor, yet in the same dimensional envelope, according to Cat.

Using MineStar Command for underground, the new R1700 (pictured) can be operated from a remote location to keep miners away from potential hazards, Cat says. “The system also boosts utilisation by allowing immediate entry after blasting and by reducing shift change time to nearly zero.”

In addition to the R1700, Caterpillar has introduced several LHDs and underground trucks equipped with EU Stage V engines and emission controls. “Reducing emissions helps miners improve the underground working environment,” it said. On top of this, and with the goal of zero underground emissions in mind, Caterpillar is continuing to develop the battery-powered R1700 XE.

Erik Elsmark, Region Manager for the Caterpillar Underground Mining Division, said: “Caterpillar and Cat dealers are supporting the whole African continent and all types of underground mining applications – big and small mines and all minerals.

“In the past several months we have delivered machines covering our full product range, demonstrating that we are well positioned to meet our customers’ needs.

“Starting with our AD22 underground articulated truck to our R2900 LHD, our equipment delivers exactly the size class and power needed for the application. With distribution centres in Southern Africa and Middle East and our dealer network in all countries of the African continent, we are able to achieve world-class service.”

The extensive line of Cat surface mining machines and technologies will also be a talking point at the event.

Caterpillar has recently expanded its line of electric drive mining trucks in the past year to include the 794 AC, 796 AC and 798 AC. Recently, a South Africa mining operation took delivery of several 794 AC trucks (pictured above), which have 291 t capacity, the company said. “This model has already proven its high productivity and superior speed on grade in a wide variety of applications,” Cat remarked.

In the Cat drill line, the latest model is the MD6200 rotary blasthole drill, designed as a production drill with the flexibility to do pre-split drilling – all in a package that Caterpillar says is its most transportable rotary drill yet. The MD6200 is designed to perform rotary or DTH drilling in single-pass or multi-pass modes and can drill holes of 127 to 200 mm in diameter, according to Cat.

Cat MineStar Command now includes systems for autonomous operation of mining trucks, semi-autonomous operation of dozers, and semi-autonomous as well as autonomous rotary drills. These systems enhance safety, boost production and lower cost per tonne, Cat says.

Mine power experts will also be on call at the show, with the representatives keen to talk about the ability for Cat generators to deliver reliable, continuous power, temporary power, or a combined heat and power solution. “The Cat team customises and installs systems for every phase of mining,” it said.

Caterpillar says it offers the industry’s widest range of diesel, gas and dual fuel generator sets; automatic transfer switches, and switchgear for seamless integration. Additionally, it offers microgrids, fully-integrated power systems that utilise solar panels, energy storage and monitoring and control systems in conjunction with any configuration of Cat gen sets.

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.

Transport

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.
