Cat to bring new D11 XE dozer, R1700 XE battery-electric LHD to MINExpo

Caterpillar is set to unveil the world’s largest, most powerful and efficient electric drive dozer with high drive at the upcoming MINExpo 2021 event in Las Vegas, USA, in September, in an exhibit themed around the concept, “together, we’re mining better”.

Caterpillar’s MINExpo 2021 experience, the company says, celebrates its partnership with mines and the ways it assists customers to mine more efficiently, effectively, safely and sustainably. The 5,124 sq.m exhibit will feature a broad range of product displays, new equipment introductions, previews of what the future holds and remote operating stations.

The exhibit will be grouped under three specific core areas: environmental, social, and corporate governance (ESG) and sustainability; technology and automation; and equipment lifecycle management solutions.

The headline exhibits come September 13-15 at the Las Vegas Convention Center will, no doubt, be the brand new Cat D11 XE dozer, the new Cat® R1700 XE battery-electric LHD (pictured, top), and new R2900 XE LHD diesel-electric drivetrain. The company also intends to display the recently released Cat 992K wheel loader, new Cat 777G water truck, Cat 794 AC electric drive truck and Cat MD6310 rotary blasthole drill.

“After waiting an extra year, the mining industry is ready to reconnect at MINExpo,” Caterpillar Resource Industries Group President, Denise Johnson, said. “We are excited to show our customers and the industry the advancements Caterpillar has made not only in equipment, technology and services but also in how we are helping customers mine more sustainably.

“While we are eager to exhibit in Las Vegas, we recognise that many of our dealers and customers will not be able to travel to the show. Therefore, we are also creating a digital Caterpillar experience at cat.com/mining, where we will place MINExpo specific content.”

Mining sustainably

Central to Caterpillar’s commitment to mining better together is helping customers meet their ESG goals and build sustainable mine sites of the future. Recognising one size does not fit all, Caterpillar has followed a strategic approach with a long-term vision of discovering, developing and delivering a broad portfolio of products, technologies, services and solutions, it said.

“This portfolio allows Caterpillar to provide a full site approach, which combines offerings with integration expertise to identify and provide the best possible solution for each specific mine,” Cat explained.

Vital to the vision of the all-electric underground mine of the future, the new Cat R1700 XE LHD will feature 100% battery-electric propulsion that generates significantly less heat and noise. It offers a 15t payload, 24,190 kg lift and tilt breakout force, and 18 km/h top speed. To optimise runtime and improve safety, batteries stay on the machine for charging, with the new portable Cat MEC500 Mobile Equipment Charger able to charge the unit in as little as 20 minutes.

The new R2900 XE LHD diesel-electric drivetrain to be displayed features a significant reduction in maintenance and repair costs, while minimising emissions. Its redesigned lift arm and components delivers up to a 39% improved lift breakout force over the R2900G, making this model up to 31 tonnes per litre more fuel efficient, Cat claims.

Cat is set to unveil what it says is the world’s largest, most powerful and efficient electric drive dozer with high drive. The new Cat D11 XE dozer will be the most advanced, lowest emission-per-tonne dozer in the industry, built to deliver the lowest cost of bank cubic meters ever.

Exhibited alongside the D11 XE, the new Cat D10 dozer (below) offers up to 4% less fuel consumption than the previous model, up to 3% more productivity with high-horsepower reverse and up to 6% more efficiency with combined load-sensing hydraulics and stator clutch torque divider, according to Cat.

The recently introduced Cat 992 wheel loader to go on show delivers up to a 32% increase in productivity. It reduces maintenance costs by up to 10% and has demonstrated in field testing up to 48% greater payload-per-fuel efficiency in applications where a four-pass match to 90.7 t trucks was achieved versus five passes with the 992K.

Caterpillar says it is committed to helping customers with their energy transitions, and the MINExpo exhibit will include a range of renewable and storable power displays, including the Cat Microgrid system. The Cat 3516 engine, meanwhile, will feature dynamic gas blending (DGB), which allows mines to save fuel and reduce emissions without sacrificing diesel performance.

Driving technology and automation

“Technology and automation are critical components for substantially improving machine uptime availability and productivity,” Marc Cameron, Vice President, Caterpillar Resource Industries, said. “Through Cat MineStar™ Solutions, Caterpillar offers customers scalable technologies to fit the mine’s specific needs. The exhibit’s technology and automation stage will focus on the real value that Caterpillar technology options provide customers.”

MINExpo will be the first opportunity for many attendees to learn more about the recently introduced Cat MineStar Edge. This solution brings visibility to the entire mining operation to show how activities early in the process impact those further down the value chain, according to the company. MineStar Edge makes it possible to measure, manage, analyse and improve the entire mining operation.

Equipped with MineStar Command for hauling, the new Cat 777G water truck provides a glimpse into the future for autonomously lowering dust levels at the mine site while maintaining haul road safety. Featuring the market’s first autonomous water delivery system, the machine integrates truck, tank and sprayer, and knows where and when to water haul roads.

Representing the Caterpillar fleet of autonomous trucks, the displayed Cat 794 AC electric drive (pictured below) will be factory-installed with Cat MineStar Command for hauling. Recently, autonomous trucks using Command for hauling surpassed 3 billion tonnes of material hauled, safely traveling more than 110 million km.

Accurate to the centimetre, the exhibited Cat MD6310 rotary blasthole drill offers technology, efficiency, safety and productivity improvements. Fully integrating Caterpillar’s components and systems, including technology and automation, the drill is capable of up to 42,149 kg of bit load and targets 203-to-311-mm hole diameters.

Exhibiting how technology can improve safety at the mine site, the Cat MineStar Detect Driver Safety System (DSS) display details how the system monitors eye closure and head pose to alert the driver via seat vibration and/or audio alarm the moment fatigue or distraction is identified. DSS has been shown to reduce 97% of the most significant fatigue events, 80% of average fatigue events and 91% of distraction events, Cat says.

Several Cat Command stations and trailers will be on display for attendees to experience effective remote control and semi-autonomous drilling, dozing and underground operations from many kilometres away.

Lifecycle solutions

Highlighting Caterpillar’s rebuild services capability, the rebuilt Cat C175-16 engine, which produces up to 2,550 kW, on display reduces overall owning and operating costs.

Team members will also be available to explain to attendees how MineStar Health maximises equipment availability and reliability by connecting the machine to the office. The service assists with proactive maintenance services and predictive equipment analysis by collecting equipment data, monitoring critical machine parameters, obtaining real-time alerts, analysing operational trends and patterns, predicting failures and receiving repair recommendations, Cat says.

Partnership and expertise

In addition to teams of workers with machine and technology expertise, representatives of Cat Financial and Cat Solutions will be on hand to share information on safety, fleet management and productivity offerings that can be combined into full site solutions.

A ThoroughTec® Simulation training will provide an opportunity to experience the 7495 electric rope shovel. In addition, attendees will be able to experience two next generation machine cabs – one for mining trucks and another for the 6060 hydraulic mining shovel – via actual cabs on display.

Cat improves efficiency and cost per tonne with 7495 mining shovel upgrades

Caterpillar has updated its 7495 and 7495 HF electric rope shovels with the result being an up to 10% increase in operating efficiency.

Drawing from more than a century of rope shovel innovation, the 2021 Cat® 7495 and 7495 HF Electric Rope Shovels (ERS) combine multiple standard feature upgrades to improve machine productivity, while component enhancements, increased frame durability and improved serviceability help reduce cost per tonne of material moved by as much as 15%.

Dan Wyatt, ERS Product Value Stream Manager, said: “Consistently, our customers tell us machine availability and productivity are primary contributors to their operation’s success. From the full adaptive control system for HydraCrowd™ to more innovative technology and data security, the advances made to the 2021 electric rope shovels reflect our commitment to meeting their needs.

“Many of these improvements are compatible with shovels in the field, so customers can realise these gains through upgrades to their existing fleets as well as new machine purchases.”

A new propel gear case for the 7495 and 7495 HF models nearly doubles the life of propel gear cases in some extreme operating conditions, Cat claims. Precise adjustments to gearing geometry and advancements in tooth hardening enhance gear case durability and productivity. The result is lower total cost of ownership of as much as $8/h when the drive system is replaced at one scheduled time.

Additionally, an ecology drain simplifies oil draining and enables kidney-loop flushing, which reduces abrasion-causing contaminants and oil change frequency.

Updates to the 7495 AC electric drive system deliver greater reliability, improved maintenance access, enhanced safety, and expanded high altitude and temperature capabilities, the company says. A liquid-cooled motion regulator cabinet efficiently dissipates heat generated by electrical components and enables operation at -40°C to +50°C and altitudes as high as 5,250 m without derating.

A faster propel transfer switch cuts lag time by 75% to improve productivity, while common motors in multiple applications means fewer parts to stock, improved parts availability and simplified maintenance, Cat says.

A reconfiguration of the crawler carriage allows drive shaft and tumbler replacement from the outboard side without removing the propel transmission. This slashes maintenance time by days while enhancing safety, Cat says. With this design, thrust loads are evenly distributed on large, tapered roller bearings rather than bronze thrust plates, increasing durability to align with 25,000-hour planned rebuilds, even in harsh environments.

Stress from every load passes through the shovel’s swing rack. This is where an enhanced design includes a single-piece rail casting that eliminates vertical segment cracks to increase durability. The rail provides a uniform path for roller movement, preventing rollers from coming loose and creating irregular wear patterns. The upgraded third rail improves access for inspection and retightening, in addition to providing added support to the thrust rail during operation. New swing girder bushings and girder-to-chassis shim designs offer improved access, reducing service time.

“All major rope shovel structures are built with high-strength steel and rugged castings, joined and thermally stress relieved to deliver reliable operation in harsh mining conditions,” Cat says. “Full penetration, profiled and ground welds are made at critical junctures, and MT, UT and X-ray inspections ensure weld quality. Structures are stress-relieved to prevent cracking, and white painted interiors facilitate inspection.”

Both the 7495 and 7495 HF ERS models now offer a full Cat bill of materials, streamlining the parts ordering process and improving parts availability, the company says.

Technology increases efficiency

Both the 7495 and 7495 HF come standard with Product Link Elite™, which transmits critical machine operating data such as utilisation, location and condition via cellular or site internet connection. Added router functionality helps to protect data security. Advanced productivity tools within Product Link Elite enable a cycle segmentation algorithm, and the combined data allows for advanced analysis of productivity, Cat says.

When linked with the available Cat MineStar™ Fleet, real-time machine tracking produces a comprehensive overview of all equipment assets to assist with fleet management and productivity.

Providing real-time feedback to improve loading efficiency, available MineStar Terrain uses guidance technology and an in-cab display to deliver precise dipper position guidance. Optional MineStar Health delivers critical event-based machine condition and operating data, while its advanced diagnostic and analytic tools improve service efficiency, the company says.

The standard Operator Assist – Enhanced Motion Control simplifies machine operation to promote high production while protecting the machine. This system is designed to yield more reliable crowd rope replacement schedules, full design life for hoist ropes, reduced wear on crowd brakes and longer life for hoist gear case components, according to Cat

HydraCrowd

A new adaptive control system (ACS) – a final piece of a multiphase enhancement initiative for HydraCrowd – delivers up to 25% cost savings on the ACS valve, resulting in up to 5% total cost of ownership saving for the entire system, Cat says. Lower initial costs, rebuildable elements and improved accessibility combine to reduce the time required for replacements. The new design also increases reliability without significantly changing the HydraCrowd maintenance schedule, according to Cat.

The new circulation filter employs two smaller, easily accessed filters that do not require roof panel removal for replacement. More affordable than the previous single-filter design, the new configuration also reduces replacement time, Cat says.

A new filter placed at the pump drive transmission improves filtration of the lubrication fluid, helping to extend the life and reliability of the system by reducing contaminants and decreasing wear. The new pump drive transmission filter assists in reducing unplanned maintenance events to decrease downtime.
