The Komatsu PC200 in South Africa — a serious 20-ton contender
For years the Komatsu PC200 has traded punches with the CAT 320 in the 20-ton excavator market. Both machines cover the same ground; they just get there slightly differently. The PC200 tends to appeal to operators who value hydraulic feel and fuel economy; the 320 appeals to fleets that value parts ubiquity above all else.
PC200-8, -10 and -11 — what changed
The PC200-8 brought KOMTRAX telematics, a genuinely modern cab and much cleaner hydraulics. It's the generation that convinced the SA market Komatsu was a real alternative to CAT. The PC200-10 added Tier 4 Interim compliance and an even more efficient hydraulic system. The PC200-11 is the current model — LED lighting, upgraded cab, ISO/SAE selectable controls and better cooling. All three are excellent machines; the -8 is the value pick, the -10 is the balanced pick, the -11 is the long-hold pick.
Common wear points to check
- Swing bearing: listen for a grinding note during a slow slew — replacement is a R 60k – R 120k job.
- Final drives: oil leaks around the sprocket hub are a warning sign.
- Boom and stick welds: look for repair welds or cracks near the pivot points — indicative of hard mining/quarry life.
- Undercarriage: as with any 20-ton excavator, the single biggest ownership cost.
Ownership economics vs the 320
Over a five-year hold, a well-maintained PC200 will usually deliver 3–7% lower total fuel spend than a comparable 320, and residual values are within a couple of percentage points either way. The right answer is often whichever machine your workshop and operators already know.
