The FrontRunner has now hauled more than all other com- mercial mining AHSs combined, according to the company. Since its first commercial deployment in 2008 at CODELCO's Gabriela Mistral copper mine in Chile, the FrontRun- ner AHS has experienced exponential growth in cumulative production, break- ing the one billion tons mark in 2016 and the 1.5 billion tons mark in late 2017. This has been accomplished with more than 130 trucks in operation to date. An additional 150 trucks will deploy to the Canadian oil sands over the next seven years. Working closely with customers, the system's 10-year zero-harm and pro- ductivity record, and unmatched ability to accommodate an array of mining environments has enabled Komatsu to accelerate the pace of AHS deployment. "AHS continues to play an increasingly crucial role in effective mine manage- ment as more and more operations transition from manned to unmanned fleets," said Dan Funcannon, vice presi- dent and general manager, Large Mining Truck Division, Komatsu America. "As the demand for autonomous systems grows, Komatsu will continue raising the bar in an effort to help mines provide safer working environments, maximize production, and reduce operating costs." Just prior to achieving the autonomous haulage milestone, Komatsu hosted a well-received, Autonomous Haulage Demonstration Day in Tucson, Ariz., showcasing the company's autono- mous haulage and assisted operations solutions. Close to 100 mining pro- fessionals, industry journalists, and students from the University of Arizo- na's mining engineering program met at Komatsu's Arizona Proving Grounds for a series of presentations, tours, and demonstrations, all supporting the event theme: Automating Progress. To underscore the company's com- mitment to progress, Komatsu plans to enhance the AHS' mixed-operation functions, enabling manned trucks of any make to interoperate with Komatsu AHS trucks in a blended operation. Komatsu is also working with industry stakeholders toward standardization of interoperability between Komatsu and non-Komatsu autonomous vehicles, to improve safety and efficiency at cus- tomer operations. Komtasu America, Komatsu Touts Frontrunner Autonomous Haulage System The all-new Cat D6 dozer delivers new levels of efficiency and performance with a choice of electric drive or fully automatic power train. A redesigned purpose-built VPAT dozer offers best-in-class grading, while updated technology features help operators to be more productive. Customer profitability is enhanced with up to 35 percent better fuel efficiency and reduced service and mainte- nance costs. An all-new cab resets the standard in comfort, while a range of configuration choices helps custom- ers optimize machine performance for business needs. At 215 hp and an oper- ating weight range of 47,949 to 53,126 lb., the new D6 replaces the versatile D6T bulldozer. This next-generation dozer offers a choice of advanced power train: the D6 XE with electric drive or the D6 with a fully automatic four-speed power shift transmission. The D6 XE is the world's first high drive electric drive dozer, offering up to 35 percent better fuel efficiency and increased agility compared to the pre- vious three-speed model D6T. Constant power to the ground, continuous push and greater maneuverability mean faster cycle times, making electric drive a top choice to achieve the highest level of productivity and fuel efficiency. Added D6 XE productivity and reduced fuel cost mean customers looking for these benefits can expect to see pay- back of the added investment over a D6 in less than two years. The D6 XE features a next-generation Electric Drive system that offers high performance along with added dura- bility. Simplified diagnostics and the serviceability advantages of a high drive dozer help reduce service and mainte- nance costs. Caterpillar, Cat Debuts High Drive Electric Dozer
