Productive, Dependable, Efficient Tier 4 Final Engine Powers New Komatsu Dump Truck

Komatsu, a leader in heavy equipment and cutting-edge technology, offers the HM300 articulated dump truck that boasts power and high levels of performance while reducing fuel consumption and operating costs. The HM300 is powered by a Komatsu SAA6D125E-7 engine that is EPA Tier 4 Final emissions certified. Komatsu’s Tier 4 Final engines are built on a solid foundation that started in 1996 with the introduction of Komatsu’s Tier 1 engines. “Productivity,” “efficiency,” and “dependability” are consistently used to describe this new piece of heavy equipment.komatsuhm300-2

Even with decreasing the fuel consumption and overall operating costs, the new HM300 offers the same capacity and vehicle weight as the previous model. Payload capacity for the truck is 30.9 U.S. tons (28 metric tons) and the gross vehicle weight is 117,881 lbs. (53,470 kg).

Improved technology and monitoring also helps to maximize overall performance and efficiency. Better and easier monitoring equals less down time and jobs are more easily completed on time and at–or under–budget. The HM300 is equipped with the latest KOMTRAX® remote monitoring technology with data access via the web or via KOMTRAX Mobile on your smart phone. In addition to providing data such as fuel levels, operating hours, location, cautions and maintenance alerts, KOMTRAX® has been further enhanced to monitor AdBlue®/DEF levels, ambient air temperatures and pressures. A new Operator Identification System reports key operating information for multiple operators. A new Auto Idle Shutdown function helps improve operating costs by reducing unnecessary idle time.

The Tier 4 Final engines continue to be honed and improved upon. The research and development team at Komatsu is world-renowned. Komatsu’s EPA Tier 4 Final engines are built on the strength of its proven Tier 4 Interim foundation. By integrating Selective Catalyst Reduction (SCR), the Tier 4 Final engine further reduces NOx emissions using AdBlue® / DEF. The Komatsu Tier 4 Final engine uses an advanced electronic control system to manage the airflow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability. The result is lower fuel consumption with no loss of performance. Komatsu continues to use a Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve for more precise temperature and air management control, as well as longer component life.

To ensure product reliability and durability in demanding conditions, Komatsu developed the entire system, including the control software that is critical to the effective operation of the after-treatment system. This control system is also integrated into the machine’s on-board diagnostics systems and KOMTRAX®, Komatsu’s standard telematics system.
