Komatsu introduce PC290LC-10 excavator
Japanese manufacturer expands the new Dash 10 range with latest hydraulic excavator
FOLLOWING the introduction of the PC240LC-10 hydraulic excavator to the European market, Komatsu have announced the launch of the PC290LC-10, the latest excavator in the new Dash 10 range.
Key benefits of the machine include: lower fuel consumption; greater operator comfort; improved efficiency; and enhanced serviceability to optimize productivity and lower operating costs.
The PC290LC-10 is powered by a 213hp (159kW), EU Stage IIIB/EPA Tier 4 Interim emission-certified Komatsu SAA6D107E-2 engine, which is said to deliver 5% more power and up to 10% less fuel consumption. A fully automatic switchable auto-deceleration system also helps to reduce fuel usage during idle conditions.
The engine uses an advanced electronic control system to manage airflow 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 have developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve for the machine, resulting in better precision and air management as well as longer component life.
All major components on the PC290LC-10 including the engine, hydraulic pumps, motors, and valves have been specially 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.
A new, fully air suspended operator control station, incorporates the side consoles mounted together with a high back, fully adjustable seat which is 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 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 easier to service these two components when required, while the air conditioning condenser is hinged to allow better access.
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 troubleshooting assistance to minimize diagnosis and repair time.
