The hydraulic system, undercarriage, frame and all major components have Komatsu’s quality and guarantee, delivering to the customer a machine with parts designed to work together and obtain the highest productivity, reliability and versatility.
The D375A-6R bulldozer has a turbocharged aftercooled SAA6D170E-5 diesel engine with a 455 [kW] 610 [hp], delivering excellent productivity and efficiency in terms of fuel consumption. This, together with the machine’s weight, make the D375A-6R a superior equipment in terms of ripping and dozing production.
The new Palm Command Control System (PCCS) allows a fully operator-controlled operational environment. Its travel control joystick provides a comfortable posture and great control for the operator, reducing the fatigue. Gearshifting is performed easily through switches. The second joystick, for blade controlling, uses a PPC (proportional pressure control) valve, which combined with its highly reliable hydraulic system, results in a smooth and precise control.
When activated, disconnects the torque converter, reducing fuel consumption and enhancing the efficiency of the power train.
The ECMV (electronically-controlled modulating valve) allows to connect the clutch smoothly. This reduces shocks while gearshifting and ensures more comfortable rides.
Komatsu, following its Ecology and Economy policy, continues to develop engines with high performance low-emission technologies, complying with the most rigorous environmental standards, such as the new EU Stage 3A and EPA Tier III emission regulations.
With this technology, Komatsu introduces its new ECOT-3 engines with total electronic control system; fuel injection (Heavy-duty and high-pressure common rail); exhaust gas recirculation (EGR); air to air aftercooler and a new combustion chamber design; and NOx, PM and fuel consumption reducing systems.
