After the introduction of the PC240LC-10 hydraulic excavator to the European market in November 2011, Komatsu Europe International today announces the launch of the PC290LC-10 the latest excavator in the new “Dash 10” range.
The key features of “Dash 10” machines centre on lower fuel consumption and better operator comfort, with improved efficiency and enhanced serviceability to maximize productivity and lower operating costs.
Weighing in at up to 30.900 kg, the PC290LC-10 is powered by a Komatsu SAA6D107E-2 engine with a flywheel horsepower of 213 hp (159 kW), and is EU Stage IIIB / EPA Tier 4 Interim emission certified. Built upon the proven Komatsu Stage 3 A / Tier 3 engine platform, the new excavator leverages Komatsu’s leadership in technology and innovation to deliver an environmentally friendly engine with 5% more power and up to 10% less fuel consumption. A fully automatic switchable auto-deceleration system can considerably reduce fuel usage during idle conditions.
The PC290LC-10 is equipped with the latest KOMTRAX™ technology, which sends machine operating information to a secure website utilizing wireless technology. Data such as operating hours, location, cautions and maintenance alerts are relayed to the web application for analysis. The KOMTRAX™ fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity.
Special features of the new PC290LC-10:
EU Stage IIIB / EPA Tier 4 Interim Emission Certified Engine
The Komatsu SAA6D107E-2 engine uses an advanced electronic control system to manage air flow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability.
As a leader in hydraulic technology, Komatsu developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision and air management as well as longer component life.
The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that doesn’t interfere with daily operation but keeps the operator aware of its status. Its regeneration system, with active or passive mode, has a manual override integrated into the monitor panel.
Highly Efficient Hydraulic System
All major components on the new PC290LC-10 including the engine, hydraulic pumps, motors, and valves are exclusively designed and produced by Komatsu. This integrated design uses a closed centre load sensing hydraulic system (CLSS) which takes hydraulic efficiency to the next level with variable speed matching. Variable matching technology allows the engine speed to adjust itself based on the machine load throughout each individual working cycle. Additional enhancements made within the hydraulic system reduce hydraulic loss and result in better efficiency and lower fuel consumption.
Enhanced Operator Comfort
A new, fully air suspended operator control station, incorporates the side consoles mounted together with a high back, fully adjustable seat, heated for improved comfort. The new cab, with ROPS compliance to ISO 12117:2008, is specifically designed for hydraulic excavators and provides a comfortable and quiet work environment where operators can maximize their productivity. The cab gains strength from a reinforced tubular skeleton framework. Viscous damper mounts provide low vibration levels, further enhancing fine control and reducing operator fatigue. An auxiliary input has been added to connect an MP3 player or other device that uses a standard auxiliary plug along with two 12 volt ports that are also included in the cab.
A new high resolution 7” LCD monitor features enhanced capabilities and displays information in 25 languages for global support. The operator can easily select up to six working modes to match machine performance to the application. These working modes include Power Mode, Economy Mode, Heavy Lift Mode, Breaker Mode, Attachment Power Mode and Attachment Economy Mode. The new Attachment Economy Mode, allows attachments to be used without compromising machine efficiency.
The new monitor panel also provides operational guidance, an Economy gauge adjustable to match desired fuel consumption level, operational records, detailed fuel consumption history, and utilization information while a standard rear view camera lets the operator see directly behind the machine.
Convenient Maintenance and Serviceability
The PC290LC-10 provides easy service access in order to reduce costly downtime. Routine service points are quickly accessible from ground level and handrails surround the upper structure for easier and safer accessibility. The radiator and hydraulic oil cooler are mounted side by side, making it simpler to maintain and service these two components when required, while the air conditioning condenser is hinged to allow even easier access. Access steps are provided in all naturally convenient positions to allow safe and quick access to the engine bay.
The machine is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which has enhanced diagnostic features that give operators and technicians greater monitoring and troubleshooting capabilities. EMMS also continuously monitors all critical systems, preventative maintenance, and provides trouble shooting assistance to minimize diagnosis and repair time.
