Komatsu delivers 9% greater performance

Its Tier 3-compliant turbocharged and aftercooled SAA6D170E-5 engine, is 64kW or 16.37% more powerful than the previous 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 mining product manager.
“Komatsu’s automatic transmission selects the optimal gear range, depending on the working conditions and load on the machine, ensuring it is always operating at maximum efficiency.
 “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.”
In dozing operations, Komatsu’s new 22m³ Fully Universal (Full-U), and 18.5m³ Semi Universal (Semi-U) blades, allow for increased production without increasing blade width or reducing digging force. The newly designed sectional shape increases load-hauling capacity during dozing operations.
“Overall dozing capability has significantly increased compared with the previous model, without compromising machine balance or operating cost,” Hall said. “The increased engine output, higher operating weight and Komatsu’s new optimised blade means productivity is up 9% compared with the previous model, while fuel consumption – despite having a more powerful engine, has reduced by more than 3%. That translates into more cubic metres of material moved or ripped per litre of fuel, a significant saving for mine operators, contractors and quarries alike,” he said.
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; and
•    An 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, and comply to ISO engineering standards,” Hall said.
