Komatsu PC290: 29–30 t excavator, generations and inspection
Komatsu PC290 — a heavy-duty crawler excavator with an operating weight of around 29–30 t. We review the -8, -10, and -11 series, key components, and what to check when buying a used PC290.
PC290 in brief
PC290 is heavier than the PC210 and lighter than the PC360, used in quarries, road construction, infrastructure, and heavy earthmoving. Its power is sufficient for intensive work, and its dimensions allow it to be transported with standard heavy-duty trailers.
This machine has been in production for a long time, so the used market offers both older and newer versions. It's used for digging, loading, and grading.
Series — what's the difference
Older versions are simpler, with less electronics. The -8 series improved comfort and efficiency; the -10 and -11 versions have stricter Stage-compliant engines, more advanced electronics, and hydraulics.
Versions with a longer undercarriage (LC) are often offered, providing more stability. Before purchasing, it's essential to determine the exact series and year of manufacture.
Engine and key components
The PC290 is powered by a six-cylinder Komatsu diesel engine. Newer versions feature SCR (AdBlue) and particulate filter systems, whose condition is crucial for the buyer.
Key components: hydraulic pumps and valve blocks, swing reducer and track roller frame, undercarriage with tracks, rollers, and idlers, boom and arm with buckets and quick couplers.
What to check when buying a used PC290
Check the engine hours and service history for any smoke, oil leaks, or if the hydraulic pressure is stable. If there's KOMTRAX, compare the data with the instrument cluster readings.
Pay particular attention to the ride and handling, steering feel, and the responsiveness of the steering wheel and gearshift. Check if the vehicle has been heavily used with a plough or digging attachments.
