KOMATSU EXCAVATOR PC650LC-8

The Komatsu excavator PC650LC-8 exceeds the Komatsu excavator PC600LC-8 in terms of performance. To give additional comfort and control for the operator on the 143,000-pound, 429-horsepower unit, the operator’s environment has been upgraded. An air-suspension seat with a heated backrest and a 7-inch LCD screen is standard in the new, exceptionally sturdy cab. A rearview camera, which is included as a standard, gives the operator the visibility and control he or she needs to optimize efficiency. Because of the rapid return circuit on the Komatsu excavator PC650LC-8 arm, just a fraction of the oil flow is returned to the hydraulic tank when the arm is in the dumping position. This decreases hydraulic pressure loss and lets the arm dump with less effort. Because of the inclusion of a new Arm Regeneration Valve, the pace of the work equipment has increased, allowing for faster loading of the trucks.

Performance and Fuel Economy

The Komatsu PC650LC-8 is powered by a Komatsu SAA6D140E-5 engine with a flywheel capacity of 429 horsepower, which drives the machine (320 kW). The electronically controlled HPCR (high-pressure common rail) fuel injection system complies with EPA Tier III emissions criteria, runs silently, is fuel-efficient, and provides power and productivity while maintaining low emissions. As stated by the manufacturer, the operating weight is 143,000 lbs, which provides ideal stability and comfort while allowing employees to maintain rapid cycle rates and high productivity levels.

Design, Comfort, and Quality

The 7-inch LCD screen is straightforward and displays data in 25 languages, providing global support. On the display panel, you have the option of selecting one of three different modes of operation: power mode, economy mode, and lifting mode. Apart from that, an image from the standard counterweight-mounted rearview camera system is shown on the monitor screen, as is information on the automatic air conditioner and machine maintenance monitoring.

The PC650LC-8 is designed to be easy to repair and maintain, resulting in less costly downtime. An equipment management monitoring system (EMMS) exclusive to Komatsu is installed on the machine, performing three basic functions and displaying them on a large LCD color monitor with a resolution of 800×600 pixels. It continually monitors all critical excavator systems, alerting the operator of any malfunctions and providing detailed instructions in the case of a failure. Because EMMS often prevents a small service problem from becoming a major service issue, operational expenditures are reduced as a consequence. Monitoring the preventive maintenance plan, providing onboard tracking, and notifying the user of any current maintenance needs are all system features. EMMS also provides technicians with error codes and troubleshooting assistance to save diagnostic and repair time.

Komatsu designed and built all of the critical components for the Komatsu PC650LC-8, including the engine, hydraulic pumps, and control valves, among other things. This is partly due to the vast cross-sectional designs, thick high tensile strength steel, inner partition walls, and large one-piece castings that provide the boom and arms with exceptional long-term endurance and resistance to twisting and bending. According to the business, Komatsu frames are produced using the most up-to-date three-dimensional CAD and FEM analysis methods.

Controllers, connections, sensors, and cabling, among other electronic components, have all undergone comprehensive testing to assure that they operate reliably even when subjected to extreme temperatures. The electrical connections are of the DT kind, which means they are resistant to dirt and water. Because metal guard rings are used to protect all hydraulic cylinders, they are more reliable than before. Hydraulic hoses use O-ring seals rather than standard taper seals to ensure they remain leak-free for a longer time during service. An extra layer of protection is provided by the typical high-pressure in-line filters situated near the pump output port. The equipment can function for longer periods if the hydraulic oil, engine oil, and filters are replaced at longer intervals.
