Komatsu Launches Powerful New PC390LC-11 Hydraulic Excavator

Komatsu  Launches Powerful New PC390LC-11 Hydraulic Excavator

Komatsu America Corp. has introduced the PC390LC-11 hydraulic excavator. With a net horsepower of 257 hp. (192 kW), the PC390LC-11 is powered by a Komatsu SAA6D114E-6 engine, which is EPA Tier 4 Final emissions certified. Komatsu’s Tier 4 Final engines are built on the solid foundation that started in 1996 with the introduction of Komatsu’s first Tier 1 engine. The culmination is today’s Tier 4 Final engine that is productive, dependable and efficient. This new excavator leverages Komatsu’s leadership in technology and innovation by delivering an environmentally friendly engine that provides high levels of performance while reducing operating costs and improving fuel efficiency.

With an operating weight between 87,388 lbs. (39,638 kg) and 89,248 lbs. (40,579 kg), the PC390LC-11 has upgraded cab features and an enhanced power mode for greater productivity and lower cost per ton. In addition to improved productivity and upgraded cab features, the PC390LC-11 maintains the same powerful lifting performance and stability of the previous model. The PC390LC-11 continues to feature one size class larger PC450 class heavy duty undercarriage components to maintain the same high lift capacity and lateral stability as the former model. The larger undercarriage has a 6% wider track gauge and offers up to 18% greater over-the-side lift capacity than the PC360LC-11.

The excavator is equipped with the latest KOMTRAX technology, which relays data such as fuel levels, Diesel Exhaust Fluid (DEF) levels, operating hours, location, cautions and maintenance alerts. A new Operator Identification System reports key operating information for multiple operators, and the new Auto Idle Shutdown function helps reduce idle time as well as operating costs.

Komatsu’s proven Tier 4 Interim foundation integrates a Selective Catalyst Reduction (SCR) system using DEF to meet EPA Tier 4 Final emission regulations for NOx emissions. The engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability. Komatsu continues to use its Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve for precise temperature and air management control as well as longer component life.

For 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. Additionally, the control system is integrated into the machine’s on-board diagnostics systems and KOMTRAX, Komatsu’s standard telematics system.

All major components on the new PC390LC-11 including the engine, hydraulic pumps, motors, and valves are exclusively designed and produced by Komatsu. This integrated design uses an efficient closed center load sensing hydraulic system and features a new enhanced power mode for improved performance and reduced cycle times.
