One Unit Only: Japan-Origin Komatsu PC850SE Just Cleared Customs — The Only One of Its Kind in China Right Now
On this page
There are machines you rent for a season. There are machines you spec into a fleet and forget about. And then there is the kind of machine that makes a quarry manager stop mid-sentence, pull out a phone, and ask: “Where is it, and can I see the hour meter?”
This is that machine.
We are not talking about a 20-ton utility digger. We are talking about the Komatsu PC850SE — an 80-ton-class (≈78,300 kg operating weight), Japanese-domestic-spec super earthmover that rolled off a vessel yesterday, cleared customs, and is now sitting in our yard as the only original-Japan PC850SE physically available in China at this moment. No sister units. No “more coming next month.” One chassis. One boom. One chance.
If you run hard rock, iron ore overburden, large-scale civil earthworks, or port reclamation, read this twice.

Why “SE” Matters — And Why Japan-Origin Is Not a Marketing Word

The PC850SE is not a longer-boom version of the standard PC850-8. It is a purpose-built Super Earthmover configuration: shorter heavy-duty 7.1 m boom + 2.945 m arm, a 4.3 m³ standard bucket (up to 5.1 m³ on later SE-8E0 spec), and a breakout logic tuned for loading rigid dump trucks, not delicate trench work.
The “SE” suffix means:
  • Bucket capacity lifted from 3.4 m³ to 4.3–5.1 m³ depending on sub-variant
  • Bucket digging force raised to 48,000 kgf (≈471 kN) vs 40,500 kgf on base PC850-8
  • Arm crowding force 38,100 kgf (≈374 kN)
  • Shorter front end → faster cycle times in face loading, better stability when rocking out of a blast pile
Now stack “Japan original” on top of that. Japanese domestic-market Komatsu iron is historically run on tighter maintenance intervals, cleaner diesel, and lower single-shift abuse than many export-region rental fleets. When a PC850SE comes back from a Japanese quarry or civil contractor, the undercarriage wear pattern, the paint history, and the hydraulic cleanliness usually tell a very different story from a machine that spent six years in a tropical open-pit with three operators per shift.
This unit is Japan-sourced, not a domestic-assembly, not a mixed-spec rebuild. That is the line item that protects resale value in Lagos, Dammam, Jakarta, or Callao.KOMATSU PC850SE machinery photoThe Numbers That Make Owners Listen
For the buyers who skip prose and go straight to the spec block:
  • Model: Komatsu PC850SE-8 / PC850SE-8E0
  • Origin: Japan, original domestic spec, imported as used unit
  • Operating weight: 78,300 kg (PC850SE-8) / 79,900 kg (PC850SE-8E0)
  • Engine: Komatsu SAA6D140E-5, 6-cyl, 15.24 L, turbo + cooled EGR
  • Rated power: 363 kW (487 hp) net @ 1,800 rpm
  • Bucket: 4.3 m³ standard SE / 4.5–5.1 m³ option
  • Max bucket digging force: 48,000 kgf
  • Max arm digging force: 38,100 kgf
  • Travel speed: 4.2 km/h high / 2.8 km/h low
  • Swing speed: 6.8 rpm
  • Fuel tank: 980 L
  • Hydraulic tank: 440 L
  • Transport size: 13,130 × 4,110 × 4,615 mm
  • Max digging depth: 7,130 mm
  • Max dumping height: 7,525 mm
  • Max ground reach: 11,945 mm
Those numbers translate into one thing on site: a 4-pass load of a 40-ton rigid truck, not a 7-pass load. Over a 10-hour shift in a granite quarry, that delta is the difference between 9,000 tonnes moved and 14,000 tonnes moved.

“Yesterday It Cleared the Gangway” — What That Actually Means for You

We do not float phrases like “just arrived” for romance. The vessel discharged yesterday. The machine is now:
  • Physically in yard, not “on the water, ETA pending”
  • Available for face-to-face inspection, cold start, full-function cycle test, undercarriage measurement, and third-party survey
  • Not yet committed to any forward contract — first confirmed deposit secures it
In the 80-ton used segment, “available today” is a scarce condition. Most serious PC850SE stock in Asia is either already spoken for by African dealers before it lands, or tied inside a rental-company refleet program. A clean Japan-origin SE that hits a Chinese inspection yard with no prior local buyer is the gap most overseas purchasers never get access to — because it is gone before the photos hit the public feed.
This one is still here. That window is measured in days, not weeks.

Why the 80-Ton Class Is the Quiet Profit Center

Everybody photographs the 200-ton miners. But the 80-ton crawler is where mid-cap contractors print margin:
  • It fits on a standard low-bed without police escort in most provinces
  • It runs a single SAA6D140 instead of a V12, so fuel burn per tonne moved stays sane
  • It can feed 30–45 t dump trucks all day without over-cycling its hydraulics
  • It survives a 70% grade, wades its own track frames through mud, and still swings 6.8 rpm loaded
  • Five years out, a clean Komatsu 80-tonner still clears 45–55% of comparable new price in USD terms across emerging markets
The PC850SE sits at the top of that band: bigger bucket than a PC490, lower operating cost than a PC1250, and a front-end geometry that quarry foremen trust more than any “upgraded” aftermarket boom.

Condition Notes Buyers Always Ask Us (Answered Up Front)

Because this is a single unit, we are not hiding behind “fleet average.” The conversation goes like this:
  • Hour meter: verified, photo-documented, not reset — available on request
  • Undercarriage: link pitch measured, roller/seal status documented, shoe width 610/710 mm depending on config
  • Hydraulics: pump pressure tested, no cross-talk, no overheating under 3-cycle load
  • Engine: cold start video, no blowby, no coolant loss, EGR cooler intact
  • Cab: EMMS monitor live, rear camera present, AC compressor engaged
  • Structure: boom/arm weld zones dye-check ready, no field repair on stress nodes
  • Papers: Japan export deregistration, bill of lading, customs clearance, FOB/CIF/CFR options
If your inspector is in Shanghai, Guangzhou, or Zhangjiagang this week, he can stand next to the track frame tomorrow. That is the advantage of “one unit, already landed.”

Who Should Not Buy This

Be straight with yourself. The PC850SE is not for:
  • Urban utility contractors digging footings and pipes
  • Anyone who needs a machine under 35 t for residential subdivisions
  • Buyers who want a 2,000-hour “like new” unit at a 12,000-hour price
  • Operators who have never run twin-pump load-sensing hydraulics and will fight the boom for a month
It is for:
  • Quarry owners loading 30 t+ trucks
  • Mine-service contractors doing overburden and ROM handling
  • Government earthwork packages with volume penalties
  • Equipment resellers in West Africa / GCC / Indonesia who know the Komatsu 80-ton resale curve cold

The Scarcity Is Not a Sales Trick — It Is Logistics

China is the largest used-excavator trading hub on earth. But “large inventory” almost never means “Japan-original PC850SE, just landed, uncommitted.” The 80-ton Japan-domestic SE units that surface here usually go three ways before public listing:
  1. Pre-sold to a Lagos or Accra dealer on the Japan yard photos
  2. Absorbed into a local mining lease as operating capital
  3. Held by a trading house for a specific Q3 shipment consolidation
That this unit cleared customs yesterday and is not on any of those paths yet is the entire story. One chassis. One buyer. Then it is someone else’s memory on a WhatsApp group.

How to Move Without Losing It

We do not run fake countdown timers. But we do run a deposit ledger. The first party to sign inspection acceptance + wire the hold deposit owns the serial number. Everyone else gets a “unit sold” stamp on the same photo set.
For overseas buyers the path is boring on purpose:
  1. Request the full walkaround video + hour-meter close-up + undercarriage gauge readings
  2. Name your destination port (Apapa, Tema, Jakarta, Jebel Ali, Callao, Manzanillo)
  3. We quote FOB Shanghai / CFR your port / CIF with marine cover
  4. You appoint a surveyor or use our partner inspector — yard visit or live video both fine
  5. Deposit secures; balance against bill of lading
  6. Load-out within 7 working days of balance
No lottery. No “maybe next shipment.” Either the serial is yours or it isn’t.

Closing — The Line From the Chinese Post, In Plain English

Scarce. One unit only. Komatsu PC850SE, Japan original import. Off the ship yesterday. The only one of its kind in China right now. Machines this size do not wait for buyers. Buyers wait for machines like this — and miss them.
That is not copywriting. That is the timeline of every clean 80-ton Komatsu that has landed in this yard for the last four years.
If your quarry is starving for cycle time, your port project is bleeding idle truck hours, or your resale yard in Durban has a hole where an 80-ton Komatsu should be — the conversation starts with a message and ends with a chassis number. After that, it is somebody else’s excavator.
Unit: Komatsu PC850SE-8 / 8E0, Japan origin, landed, uninspected-by-you-yet.
Status: Available. Singular. Not replenishable.
Next move: yours.
