New excavator from Komatsu

Japanese construction equipment manufacturer announces launch of PC240LC-10 excavator

THE introduction of the PC240LC-10 hydraulic excavator to the European market marks the launch of Komatsu’s new-generation Dash-10 range, which has been designed to offer improved performance and fuel economy, better operator comfort and enhanced serviceability to optimize productivity and reduce operating costs.

Powered by a Komatsu SAA6D107E-2 engine that delivers 177hp (132kW) and is EU Stage IIIB/EPA Tier 4 Interim Emission certified, the new PC240LC-10 model delivers 5% more power and up to 10% less fuel consumption. The machine is also equipped with a fully automatic switchable auto-deceleration system that can further reduce fuel usage during idle conditions by up to 30%.

The SAA6D107E-2 engine utilizes an advanced electronic-control system that manages airflow rate, fuel injection, combustion parameters and after-treatment functions to maximize performance, reduce emissions and provide an advanced diagnostic capability.

The company has also developed its own hydraulically actuated variable geometry turbocharger and an exhaust gas recirculation valve for the new excavator model, resulting in better precision and air management, as well as longer component life.

All major components on the PC240LC-10, including the hydraulic pumps, motors and valves, have been designed and produced by Komatsu. This integrated design uses a closed-centre load-sensing hydraulic system with variable speed matching.

According to Komatsu, variable matching technology allows the engine speed to adjust itself based on the machine load throughout each individual working cycle. The additional improvements on the hydraulic system reduce hydraulic loss, providing increased efficiency and reduced fuel consumption.

The new, fully air-suspended operator cab incorporates side consoles together with a high back, fully adjustable heated seat for enhanced operator comfort. The ROPS-compliant cab is specifically designed for hydraulic excavators, featuring a reinforced tubular skeleton framework and viscous damper mounts that deliver low vibration levels to reduce operator fatigue.

The PC240LC-10 is equipped with a new 7in LCD monitor that displays information in 25 languages for global support. The operator can select six different working modes on the monitor panel – Power, Economy, Heavy Lift, Breaker, Attachment Power and Attachment Economy. The new Dash-10 model also includes Komatsu’s sophisticated Equipment Management and Monitoring System and Komtrax monitoring technology.
