Komatsu D375A-6 dozer delivers improved performance

The new D375A-6, is powered by Komatsu’s Tier 3-compliant turbocharged and aftercooled SAA6D170E-5 engine rated at 455 kW (Net), a 64 kW or 16.37% increase in engine power compared with the previous Komatsu D375A-5 dozer making the -6 the most powerful machine in its class.
The fuel-efficient engine ensures superior performance in both ripping and dozing work, according to Michael Hall, Komatsu Australia’s national product manager mining.
“The increased power and reduced fuel consumption characteristics of this engine are unique to Komatsu; when coupled with our automatic gearshift transmission and lockup torque converter the results are groundbreaking,” he said.
“Komatsu’s automatic transmission selects the optimal gear range depending on the working conditions and load on the machine, ensuring the machine is always operating at maximum efficiency.
“These performance, productivity and efficiency benefits are achieved through Komatsu’s philosophy of integrated design, which ensures that all components, powertrain, frame, hydraulics, electronics are designed to work together,” said Hall.
“Ripping performance is further enhanced through Komatsu’s electronic powertrain control system, which results in a highly efficient drawbar pull, putting more power to the ground where it counts.”
Also new on the D375A-6 is a package of “standard mine” specification options, ensuring the dozer can be delivered directly from factory to minesite in a “mine-ready” configuration.
These include:
• Right- and left-hand access platforms with handrails, toerails, access lights and work lights, giving safe, secure access for operators and maintenance crews to the side and rear of the machine, including checking and refilling fuel and hydraulic tanks, cleaning of cab windows, and checking cab mounted lights
• High mounted HID (high-intensity discharge) headlights for safer working at night
• A battery and starter isolator box
• Centralised grease points
• Manual engine stop switches
• Engine bay maintenance light.
“This option saves considerable time and expense, and ensures that mine specification requirements are manufactured and installed to Komatsu’s exacting production standards prior to being shipped to Australia, and comply to ISO engineering standards,” said Hall.
Brief specifications of the D375A-6 are: Operating weight, 71.64 tonnes; powered by Komatsu SAA6D170E-5 engine rated at 455 kW (Net); blade capacity, 18.5 cu m (semi-U), 22 cu m (full-U).
