PC270LC-8 Driven by Improvements in Efficiency, Operator Comfort and Fuel Economy

Vernon Hills, IL, May 23, 2006”Komatsu America Corp. today introduced its new PC270LC-8 hydraulic excavator.  Distinguished by enhancements in efficiency and information technology upgrades, the hydraulic excavator offers improved operator comfort and a new low emission engine that improves fuel consumption. Primarily used for general contracting and underground utilities installation, this powerful excavator has a flywheel horsepower of 187 HP and an operating weight of 63,934 to 66,028 pounds. The PC270LC-8 exemplifies the Komatsu design concept of matching highly efficient engines and advanced hydraulic systems to provide leading edge productivity and low-cost operation. 


The new PC270LC-8 is standard-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 wireless equipment 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 PC270LC-8 include:


  • Low emissions and reduced fuel consumption,

The excavator is equipped with the newly-developed, powerful, low emission Komatsu SAA6D107E-1 engine that significantly reduces NOx emissions with an accurate multi-staged fuel injection system.  The engine meets EPA Tier 3 and EU stage 3A emission regulations without sacrificing power or machine productivity. The economy mode further improves fuel consumption with an eco-gauge for energy-saving operations and an operator caution for extended idling.


  • Hydraulic system complements efficiency

Significant improvements to the hydraulic system greatly enhance the productivity and efficiency of the PC270LC-8 excavator.  These include an improved pump flow merge divide valve, and high-efficiency hydraulic components which reduce pressure loss. In addition, the new arm quick return circuit reduces overall cycle times, thereby improving productivity even more.

  • Operator comfort a top priority

Komatsu™s dedication to continually improve operator comfort ensures the highest levels of operator productivity and efficiency. The new innovative hydraulic excavator cab design continues to offer high visibility and is reinforced with a seamless tube structured cab framework to protect the operator in the event of a tip or rollover. Noise is significantly reduced to that of a premium automobile and the cab damper mounting system combines with a high rigidity deck for decreased cab vibration. The highly pressurized cab also has an automatic air conditioner with a bi-level control function for ultimate operator comfort. In addition, the seat and console are designed with console mounted armrests that enable the operator to adjust for maximum comfort.

  • Large multi-color monitor for the best view

The easy-to-view 7-inch color monitor supports accurate and smooth work and displays data in 10 languages.  For increased operator awareness, views from the optional counter-weight mounted camera also display in color on the monitor. The multi-function monitor has a Power mode, Economy mode, Lifting mode, Breaker operation and Attachment mode. 


  • Simple and precise breaker and attachment control

The PC270LC-8 offers fingertip command of two different breaker and attachment flow selections, providing a total of four flow settings. Each flow setting can be easily adjusted to match the demand of the attachment on hand, and the password protection system can be enabled to prevent unauthorized adjustment.


  • Easy maintenance and lower operating costs

The PC270LC-8 is equipped with the EMMS (Equipment Management Monitoring System), which includes a maintenance function and trouble data memory function. The machine controllers continually monitor machine condition before start-up and during operation.  Any abnormalities are immediately displayed.  This smart monitor also notifies replacement time of oil and filters, and stores abnormalities for effective troubleshooting.  All of Komatsu™s conventional excavators come standard with the company™s unique high-pressure in-line filters installed at each pump discharge port to provide additional hydraulic system protection with the already installed high efficiency return filters.


  • Aggressive productivity features

The PC270LC-8 utilizes the next size class up (PC300) track frames and drive components such as the final drives and travel motors. The standard overall width of 11™2 provides exceptional lateral stability while the high 56,000 pounds of drawbar pull allows the machine to easily overcome poor underfoot conditions.
