Komatsu America Corp. Launches the New PC290LC-11 Hydraulic Excavator
Komatsu America Corp. has introduced the PC290LC-11 hydraulic excavator. With a net 196 HP (147 kW), the PC290LC-11 is powered by a Komatsu SAA6D107E-3 engine and 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. The resulting benefit today is a Tier 4 Final engine that is productive, dependable and efficient. This new excavator leverages Komatsu’s leadership in technology and innovation by delivering a more environmentally friendly engine that provides high levels of performance while reducing fuel consumption and operating costs.
With an operating weight range between 66,359lbs (30,100 kg) and 68,122 lbs. (30,900 kg), the PC290LC-11 features improved efficiency, lower fuel consumption, improved operator comfort, and enhanced serviceability to maximize productivity while lowering operating costs.
The PC290LC-11 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 DEF levels, ambient air temperatures and pressures. A new Operator Identification System reports key operating information for up to 100 operators. A new Auto Idle Shutdown function helps improve operating costs by reducing unnecessary idle time.
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 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, which 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.
Highly Efficient Hydraulic System
All major components on the new PC290LC-11 including the engine, hydraulic pumps, motors, and valves are exclusively designed and produced by Komatsu. This integrated design uses a closed center load sensing hydraulic system, which has taken hydraulic efficiency to the next level using Variable Speed Matching technology. Variable Speed Matching allows the engine speed to adjust based on the hydraulic pump output for both light and heavy-duty applications. Additional enhancements have been made within the hydraulic system to reduce hydraulic loss, resulting in better efficiency.
Operator Environment
The PC290LC-11 cab provides a comfortable and quiet work environment to help operators maximize productivity. The ROPS certified cab specifically designed for hydraulic excavators gains strength from a reinforced box structure framework. The cab is mounted on viscous isolation dampers that help limit low vibration levels. It features a standard air suspension high back seat with newly designed fully adjustable armrests and heat for improved comfort is also included. In addition to the standard radio, there is an auxiliary input for connecting external devices to play music through stereo cab speakers. Additionally there are two 12-volt power ports incorporated into the cab. Optional joysticks are available with proportional controls for operating attachments.
A high-resolution 7” LCD color monitor features enhanced capabilities and the operator can easily select up to six working modes to match machine performance to the application. The monitor panel provides information on DEF fluid level, ECO guidance, operational records, fuel consumption history, and utilization information. A standard rearview camera with wide landscape allows the operator to view directly behind the machine.
