Komatsu offers a preview of its latest mining class "intelligent' dozer
Komatsu America Corp recently previewed its new 636HP, D375Ai-8 intelligent machine control crawler dozer. Featuring more production and faster cycle times, including 20% more horsepower in reverse than the prior model, the first mining-class dozer equipped with intelligent machine control also comes with structural enhancements for increased durability of mainframe and track frame. The D375Ai-8 also features improved undercarriage, cab mounts and seat, for overall operator comfort. In 2017, a remote-control machine option will be available for difficult applications.
The dozer packs a powerful, Tier 4 Final, 636HP in forward and class-leading 775HP in reverse, SAA6D170E engine that offers faster cycle times and up to five percent more productivity than the prior model with no Selective Catalytic Reduction (SCR) system needed. Additional features include a variable geometry turbocharger (VGT), dual diesel particulate filters and large capacity & high efficiency EGR coolers.
Whether its reclamation, large construction or production mining applications, the D375Ai-8 is the right machine for the job, “said Joe Sollitt, product manager, Komatsu America. “Between the extra horsepower and the addition of intelligent machine control, this will be one of the most productive machines on the market,” Sollitt said.
“Operators are empowered with more data and more automated capabilities than ever before in a mining-class Komatsu dozer,” said Jason Anetsberger, senior product manager, Komatsu America. “Extending the benefits demonstrated with intelligent dozers in the smaller construction-size classes to mining applications will mean bigger machines can produce even bigger results for our customers,” Anetsberger said.
Eliminating the need to install and remove blade-mounted sensors each day not only saves on machine and operator wear and tear, it converts potential downtime into more time spent running the machine.
First-to-last pass, rough-to-finish automatic dozing extends production gains. Once engaged, the system automatically cuts and lowers the blade to grade in a typical dozing pass. If the load increases to a maximum, the blade automatically raises to minimize track slip to keep dozing productively.
