Rolling Meadows, IL, September 24, 2007”Komatsu America Corp. announces the PC300LC-8 hydraulic excavator. A leader in excavator technology and design, Komatsu™s latest series delivers maximum digging force with excellent fuel economy in the toughest of digging conditions. This new excavator series maintains the solid reliability of the previous model but now offers reduced noise levels inside the cab.
The PC300LC-8, with a flywheel horsepower of 246 HP, has an operating weight of 77,093 to 79,152 pounds, is powered by a Komatsu SAA6D114E-5 engine. The electronically controlled HPCR (High Pressure Common Rail) fuel injection system is EPA Tier 3 emissions certified, provides low noise operation, and remains extremely fuel efficient while delivering superior power and productivity.
The PC300LC-8 is equipped with the latest Komtrax technology (Level 3), 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 PC300LC-8 include:
- New Large Multi-Color Monitor
The easy-to-view 7 LCD monitor enables accurate smooth work and displays data in 10 languages for global support. There are five modes of operation that may be selected through the monitor panel: Power Mode, Economy Mode, Lifting Mode, Breaker Mode and Attachment Mode. The monitor panel also displays the automatic air conditioner, machine maintenance tracking, and the image from the standard, counterweight-mounted rearview camera system.
- Enhanced Operating Efficiency through Easy Maintenance and Serviceability
The PC300LC-8 provides easy service and maintenance access in order to reduce costly downtime. The radiator and hydraulic oil cooler are mounted side by side, making it simpler to maintain and service these two components when required. The machine is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), which performs three main functions that are displayed on the large LCD color monitor. EMMS continually monitors all critical excavator systems, alerting and guiding the operator should an abnormality occur. EMMS often prevents a small problem from becoming a major service issue, contributing to reduced cost of operation. Second, the system tracks the preventative maintenance schedule, provides on-board tracking, and advises current required maintenance. Third, EMMS provides error codes and troubleshooting assistance to mechanics in order to minimize diagnosis and repair time.
- Built For Durability And Reliability
All major components on the new PC300LC-8 including the engine, hydraulic pumps, motors, and control valves are exclusively designed and produced by Komatsu. The boom and arms exhibit long-term durability and are highly resistant to bending and torsional stress due to large cross-sectional structures, thick high tensile strength steel, interior partition walls, and large one piece castings. Komatsu frames are designed using the most advanced three-dimensional CAD and FEM analysis technology.
Highly reliable and exclusively designed electronic components such as controllers, connectors, sensors, and wiring have undergone extensive testing to ensure reliability in the harshest conditions. The electronic connectors are DT-type and seal against dirt and moisture. All hydraulic cylinders are protected by metal guard rings for additional reliability. Hydraulic hoses are equipped with O-ring seals versus conventional taper seals to provide extended leak-free life. The standard high pressure in-line filters at the pump outlet port provide an extra level of protection to the hydraulic system. Long replacement intervals for hydraulic oil, engine oil, and filters keep the machine up and running for increased hours on the job.
- Versatility To Match Different Job Applications
The PC300LC-8 comes equipped with two boom mode settings, five working modes, and Power Max control. These modes are designed to match engine speed, pump flow, and system pressure to specific application requirements, providing the operator with the flexibility to match equipment performance to the job at hand. With many excavators operating a wide variety of working attachments, the PC300LC-8 is equipped with Breaker Mode (single action circuit) and Attachment Mode (double action circuit) which allow the operator to adjust hydraulic flow directly from the cab through the large monitor panel. The attachment flow control has been improved and is more flexible for effortless attachment adjustments. In hard digging applications, a one-touch Power Max Function increases digging force by 7% for 8 seconds, creating a noticeable difference in digging performance.
- Cab Enhancements Provide Comfortable Working Environment
A wide spacious cab with a high back operator seat provides excellent support and comfort for reduced fatigue and higher productivity. The multi-position, PPC (pressure proportional control) levers and armrest integrated with the console levers allow the operator to work in comfort while maintaining precise control. The highly pressurized cab keeps dust from entering the operator™s compartment, while its rigid frame offers wide visibility and has excellent sound absorption. The multi-layer viscous cab mounting system incorporates longer stroke and the addition of a spring. Combined with a high rigidity deck, the new cab damper mounting reduces noise and vibration levels at the operator seat. A high capacity automatic heater/defroster/air conditioning system is incorporated into the new monitor panel and is provided as standard equipment.
