Komatsu D375A-8 Crawler Dozer: LEANER, MEANER, MORE PRODUCTIVE
Mar 5, 2020, 13:56 PM by Jeff Richards
The new, Komatsu D375A-8 mining-class dozer offers higher productivity, better durability and improved operator comfort.
The dozer is equipped with a Tier 4 Final engine that produces 20% more horsepower in reverse, resulting in faster cycle times and up to 18% higher productivity.
Durability on the dozer has also been improved, thanks to structural enhancements on the track frame and mainframe that will increase the life of major components.
“Whether it is used for reclamation, large construction or production mining applications, the D375A-8 is the right machine for the job,” said Joe Sollitt, product manager, Komatsu America. “The durability improvements to this new model drive down the total cost of ownership while the more powerful Tier 4 Final engine significantly increases performance and production.”
Along with enhancements to the frame, the dozer has a new single-link blade support and larger trunnion bearings that reduce maintenance, increase blade stiffness, and minimize blade shake.
Komatsu also took several steps to improve operator comfort, which can result in higher productivity. “Improvements to the undercarriage, cab suspension and operator interface will make D375A-8 operators more comfortable and productive throughout their shift,” Sollitt said. Those improvements include larger cab mounts to better absorb shocks, a new heated and ventilated operator’s seat, and a new, more ergonomic cab layout.
The dozer gives operators better visibility to the cutting edge and ripper point, and standard features like ripper auto-return and shoe slip control decrease operator fatigue.
The new Tier 4 Final engine doesn’t require Diesel Exhaust Fluid or a Selective Catalytic Reduction system, so maintenance is easier. Other ease-of-maintenance improvements include a full wrap-around rear platform, ground-level fluid service center, ground-level fast fuel coupler, and centralized fluid sampling and PM service connecters.
