Komatsu launches new crawler dozer


Komatsu is launching a new crawler dozer with greater horsepower for increased operator productivity.

The D375A-8 features an EPA Tier 4 Final-certified engine with a high-pressure, common rail, fuel injection system that produces 20% more power when traveling in the reverse gear that the company believes will lead to faster cycle times.

In total, the mining-class dozer has a net horsepower of 609hp traveling forward and 748hp in reverse, and does this without the need for selective catalytic reduction or diesel exhaust fluid. In addition, it boasts dual diesel particulate filters and large exhaust gas recirculation coolers, while a variable geometry turbocharger improves low speed response.

The new machine comes with structural enhancements for increased durability of the mainframe and track frame, and includes 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 at 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,” Sollitt said.
