Frequently Asked Questions about Komatsu excavator Excavator
The Komatsu PC220 (especially the PC220-8 and PC220-8M0 series) stands out due to its “Total Vehicle Control” system. Unlike many competitors that assemble third-party components, Komatsu manufactures its own engine, hydraulic pumps, and control valves. This integration allows for a highly synchronized hydraulic flow, resulting in faster cycle times and a 5-10% improvement in fuel efficiency compared to non-integrated systems. For buyers of a used Komatsu excavator, this means the machine maintains its “surgical” precision even after 10,000+ hours of operation.
The PC220 is typically equipped with the Komatsu SAA6D107E-1 engine, which utilizes a high-pressure common rail (HPCR) fuel injection system. This technology ensures complete combustion and reduces particulate matter. The machine features six working modes (P, E, L, B, ATT/P, and ATT/E), allowing operators to shift into “Economy Mode” for light lifting or “Power Mode” for heavy-duty trenching. When purchasing a used Komatsu, it is vital to check the KOMTRAX logs to ensure the engine has been operated within optimized RPM ranges to guarantee longevity.
When vetting a used excavator, the PC220’s hydraulic “closed-center load sensing” (CLSS) system must be the priority. Check the main pump for abnormal noise and inspect the “Arm-in” and “Boom-up” speeds for any signs of hesitation. A professional inspection by Taihong Machinery includes a hydraulic pressure test to ensure the pump output meets the factory standard of 33.3 MPa. Additionally, verify the integrity of the hydraulic oil cooler, as Komatsu machines are known for their excellent heat dissipation, but only if the cooling fins remain unobstructed.
Yes, the PC220 is a robust choice for rock-breaking tasks, provided it is fitted with the correct hydraulic breaker piping. Its X-track frame is specifically reinforced with a large-section structure that resists torsional stress better than standard flat frames. However, for continuous mining, we recommend checking if the unit has the “Heavy Duty” (HD) boom and arm configuration. These versions feature thicker steel plates and internal baffles, making them the preferred choice for high-abrasion environments.
The Komatsu PC220 is legendary for its “second life.” It is common to see these machines reaching 20,000 to 25,000 operating hours with original major components if maintenance schedules are strictly followed. Due to the global availability of Komatsu parts and the simplicity of its mechanical architecture, it retains one of the highest resale values in the 22-ton class. At Taihong Machinery, we ensure every used Komatsu in our inventory has a clean chassis and a verified undercarriage, ensuring your investment holds its value for years to come.
