The D375A-8 features an EPA Tier 4 Final certified engine that produces over 20 percent more horsepower while the dozer is traveling in the reverse direction. The additional horsepower yields faster cycle times and a productivity increase of up to 18 percent.
Komatsu America Corp., a leading global heavy equipment manufacturer, introduced the D375A-8 crawler dozer Sept. 26. The D375A-8 features an EPA Tier 4 Final certified engine that produces over 20 percent more horsepower while the dozer is traveling in the reverse direction. The additional horsepower yields faster cycle times and a productivity increase of up to 18 percent.
This mining-class dozer also comes with structural enhancements for increased durability of the mainframe and track frame. The D375A-8 also features an improved suspended undercarriage, larger viscous cab mounts, and a new air-suspension heated and ventilated seat for overall operator comfort.
“Whether its 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. The improvements to the undercarriage, cab suspension, and operator interface will make D375A-8 operators more comfortable and productive throughout their shift."
