Komatsu PC — what the number and dash figure actually tell you
Anyone typing “Komatsu PC120” or “PC100” is usually trying to decode the label: PC is Komatsu's crawler-excavator designation, the following number places the model roughly in a size class, and a dash number at the end marks the generation.

Recent generations run under labels such as -8, -10 or -11; each update brings a revised engine, hydraulics and cab plus tighter emissions rules, while the base number stays the same. The added letter LC marks a widened, lengthened undercarriage that spreads more contact area on soft soil.
Alongside the PC line, Komatsu also sells models such as H135S, H455S or H655S, a separate family for very large open-pit excavators tracing back to the earlier partnership with German manufacturer Demag. Its letter-and-number logic follows its own rules and does not map onto the PC models.
The “Komatsu Hydraulic Excavator” collective entry holds both families side by side, from compact excavators starting around 53 kW up to the large H-series machines. When buying used, check the hour meter along with track rollers, chain tension and cylinder seals.
In short: the number after PC signals the size class, the dash number the generation, and models like PC100, PC120 or H655S show how wide a range sits under one register entry.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
