KOMATSU PC270-8: The 27-Ton “Sweet-Size” Excavator That Does the Work of a 30-Tonner
On this page
Every equipment dealer knows the truth: the 20-ton class is crowded, and the 30-ton class is expensive. The smart money in 2026 is sitting right in the middle — the Komatsu PC270-8 / PC270LC-8, a 27–29 ton crawler excavator that blends 20-ton transportability with 30-ton production. For contractors who trench highways, load trucks on earthwork projects, strip overburden, or run rental fleets across Africa, the Middle East, Southeast Asia, and Latin America, the PC270-8 is the machine that “just fits.”
It is not the biggest Komatsu. It is not the cheapest. But in the used market, it is one of the easiest machines in the 25–30 ton range to buy, ship, rent, run, and resell.

1. Why the 27-Ton Class Exists — and Why Buyers Love It

A PC200-8 is great until the soil gets hard, the trench gets deep, and the trucks get bigger. A PC300-8 is powerful, but heavier, thirstier, and harder to move between sites.
The PC270-8 sits in the gap:
  • Operating weight: 27,140–28,050 kg (PC270-8), 28,040–29,020 kg (PC270LC-8)
  • Bucket capacity: 1.14–1.26 m³ standard, 1.30–1.50 m³ common on China-market units, up to ~1.6 m³ options
  • Transport size: 9,860 × 3,190 × ~3,200 mm — still a normal lowbed/flat-rack load
  • Tail swing: 2,940 mm — standard tailswing, stable on slopes and trench edges
In plain language: you get close to PC300 output, but you pay PC270 money and move it like a big PC200.

2. Engine: Komatsu SAA6D107E-1 — The Same Heart as the PC200 Family

The PC270-8 runs the Komatsu SAA6D107E-1 — a 6-cylinder, 6.69 L, turbocharged, air-to-air aftercooled diesel.
  • Gross power: 149 kW / 200 HP @ 2,050 rpm
  • Net power: 140 kW / 187 HP @ 2,050 rpm
  • Emissions: EPA Tier 3 / EU Stage IIIA — no DPF, no SCR, no AdBlue
  • Fuel tank: 400 L — long shifts, fewer refuel stops
For importers, this is the magic sentence: Tier 3, not Tier 4. In markets where diesel quality is inconsistent and urea is unavailable, the SAA6D107E-1 starts, loads, and survives. The same engine family powers thousands of PC200-8 and PC220-8 machines worldwide, so filters, injectors, water pumps, and turbo parts are easy to source from Dubai to Lagos to Jakarta.
Komatsu quotes ~10% lower fuel consumption vs the PC270-7 thanks to integrated engine + hydraulic + electronic control.

3. Hydraulics: Komatsu HydrauMind — Smooth, Strong, Predictable

The PC270-8 uses Komatsu’s HydrauMind closed-center load-sensing hydraulic system:
  • Max pump flow: 450 L/min (2 × variable displacement piston pumps)
  • Main relief pressure: 37.3 MPa (equipment & travel), 28.9 MPa (swing)
  • Swing speed: 10.5–11.5 rpm
  • Travel speed: 5.5 km/h high / 3.1 km/h low
  • Gradeability: 70% (35°)
Digging forces are the headline:
  • Bucket digging force: 198–202 kN (ISO) — about 20,200 kgf
  • Arm crowding force: 138–141 kN (ISO) — about 14,100 kgf
That means the PC270-8 bites hard in compacted fill, clay, and weathered rock — and still feathers nicely when you are working around pipes and footings. Operators who come off a PC200 say the PC270 feels “planted.” Operators who come off a PC300 say it “costs less but does 90% of the job.”

4. Working Range: Deep Trenches, High Loading

With the standard boom and ~3,045 mm arm:
  • Max digging depth: 6,500 mm (PC270-8), 6,460 mm (PC270LC-8)
  • Max digging height: 10,000 mm
  • Max dumping height: 7,060 mm
  • Max reach at ground level: 10,000 mm
  • Max digging radius: 10,190 mm
Practical translation:
  • Loads a 15–20 ton dump truck in 3–4 passes with a 1.3 m³ bucket
  • Trenches for water/sewer/fiber at 2.0–3.0 m depth without constant repositioning
  • Handles foundation excavation, site cut/fill, canal cleaning, and light quarry edge work
  • PC270LC-8’s longer carbody = better flotation in soft ground and more stability when lifting over the side

5. PC270-8 vs PC270LC-8 — Which One to Import?

  • PC270-8: 600 mm shoes standard, 27.1–28.05 t, shorter track frame, better for hard ground and easier transport
  • PC270LC-8: longer undercarriage, 700 mm shoes standard, 28.04–29.02 t, better flotation in mud/sand, more stability for lifting and slope work
For general civils and rental: PC270-8 is the safer default.
For soft soil, swamp-edge, pipeline, and Middle East desert access roads: PC270LC-8 is worth the extra weight.

6. Cab, Controls & Operator Comfort

Komatsu built the -8 cab for all-day work:
  • 7-inch multi-function color LCD monitor, 12-language support
  • ROPS cab (ISO 12117-2), slip-resistant plates, large side/rear mirrors
  • Cab damper mounting = lower vibration and ~1 dB lower noise vs PC270-7
  • PPC hydraulic controls — light joysticks, low fatigue
  • Optional rear-view camera, A/C, suspension seat, cab front/roof guards
  • KOMTRAX-equipped on many units (remote location/fuel/health data)
For rental fleets, this matters: a comfortable cab = fewer operator complaints, fewer “I can’t see” incidents, and better resale because the machine comes back in one piece.

7. Maintenance: Made for Sites Far From a Dealer

The PC270-8 is a mechanic-friendly machine:
  • Remote-mounted engine oil filter and fuel drain valve
  • Standard fuel pre-filter with water separator — protects injectors in humid/dusty markets
  • Side-by-side cooling modules — radiator and oil cooler serviced individually
  • Longer intervals for engine oil, engine oil filter, and hydraulic filter vs older generations
  • 400 L fuel tank, 132 L hydraulic tank, 23.1 L engine oil, 20.6 L coolant
Komatsu’s global network is one of the strongest in the industry. But even without a dealer nearby, the SAA6D107E-1 and HydrauMind pumps are well-documented and widely supported in the aftermarket.

8. Why Buy a Used PC270-8 From China?

New 27–30 ton Japanese excavators are expensive and often Tier 4-complicated. A verified used PC270-8 from a transparent Chinese export yard gives you:
  • Japanese core components at a fraction of new price
  • Tier 3 simplicity for tough-fuel markets
  • 27-ton size = cheaper ocean freight than 30–35 ton machines
  • Strong rental demand: bigger than a mini, cheaper than a 30-tonner
  • Excellent resale in Africa, SEA, the Gulf, Central Asia, and Latin America
Typical China-export pricing for verified units runs roughly USD 28,000–46,000 depending on year, hours, UC life, AC, breaker piping, and whether it is PC270-8 or PC270LC-8. Against a new machine at 2–3× the price, the ROI is obvious.

  • Equipment importers — Komatsu badge + 27-ton versatility = easy flip
  • Quarry/aggregate support — feeder loading, overburden, stockpile work
If you are running a PC200 and constantly hitting its ceiling — or looking at a PC300 and choking on the price — the PC270-8 is the “grown-up 20-ton, baby 30-ton” answer.

Most fleets do not need a PC300 every day. They need a PC270-8 that can pretend to be one.

12. The Bottom Line

The Komatsu PC270-8 will not win likes for its dashboard. It wins for the only thing that matters: tons moved per dollar, per hour, per year. A Tier 3 Komatsu engine that starts in the heat. A HydrauMind hydraulic system operators trust. A 1.3 m³ bucket that fills trucks fast. A 27-ton footprint that ships cheap and rents easy. A Japanese name that buyers recognize before they ever see the paperwork.
For owner-operators counting fuel, for rental yards counting utilization, and for importers who need inventory that sells before it lands — the PC270-8 is the quiet money-maker of the mid-heavy class.
Big enough to produce. Small enough to profit. Japanese enough to trust.
