The Komatsu PC450-8 sits in the heavy 45-ton class that quarry, mining and large earthworks buyers shortlist when a 20–22 ton machine is no longer enough. If you are searching for a used Komatsu PC450-8 excavator for sale with China export and Shanghai loading, this guide explains which units to shortlist, what to film before deposit, and how shipping usually works.

Why overseas buyers shortlist the PC450-8

Across African mining sites, Middle East quarry yards and Latin American infrastructure jobs, the PC450-8 competes with CAT 349/352, Hitachi ZX450/ZX470 and Volvo EC480. Buyers like Komatsu when local mechanics already know the filters, pumps and undercarriage pattern, and when a Japanese-origin heavy unit is expected to hold resale better than an unknown local brand. Marketing titles sometimes mix PC450-7, PC450-8, PC490 and older PC400 machines — confirm the serial plate and monitor string in one continuous video.

Match the machine to the job

Quarry and truck loading: prioritise rail height, sprocket tips and a quiet main pump under a loaded dig cycle.
Mining or hard digging: confirm rock bucket or heavy-duty stick options, boom foot cracks and any active hydraulic codes.
Hammer or shear work: ask for breaker piping history and stick reinforcement photos.
Budget trap: a cheap PC450 with worn rails or a noisy pump can cost more after landing in Lagos, Mombasa, Tema or Callao than a slightly higher FOB unit with honest undercarriage remaining.

Remote inspection checklist for a 45-ton excavator

Serial plate + hour meter in one continuous shot — avoids mismatched stickers.
Cold start — smoke colour, idle hunting, blow-by on a large diesel.
Full dig cycle under load — boom, arm, bucket, swing; listen for pump whine and cavitation.
Travel straightness — skewed travel often means roller, idler or frame issues that are expensive at this tonnage.
Undercarriage close-ups — rail height, sprocket tips, pad bolts, leaks; price rails separately.
Boom and stick stress points — wipe paint at boom foot, stick nose and bucket linkage.
Cab and electrics — lights, A/C, monitor codes, backup camera if fitted.

PC450-8 vs CAT 349 and ZX450 class

Komatsu often wins where operators already trust the brand and filter stocks exist. CAT wins where dealer density is high. Hitachi wins when multi-function hydraulics and local rail stocks favour that badge. Landed cost is what matters: freight from Shanghai, undercarriage remaining life, and how fast your local shop can source a pump or final drive if something fails in month three.

Shipping a tired undercarriage on a 45-ton machine usually costs more than paying a slightly higher FOB Shanghai price for a cleaner unit.

Shanghai export: FOB, CIF and packing

YCHS Machinery loads used excavators from the Shanghai area on flat-rack or bulk. Typical choices are FOB Shanghai or CIF your port once stick/bucket removal and discharge rules are clear. Heavy machines often need careful lashing plans and sometimes stick removal for height. Request wash photos, a lashing plan and draft commercial documents before sailing. Age limits, emissions and import licences at destination remain the buyer’s responsibility.

Documents and payment discipline

Ask for a commercial invoice draft, packing list draft, and the exact serial before you pay more than a small holding deposit. Prefer bank transfer to the exporting company named on the invoice — not a personal account. YCHS can host a third-party surveyor at the Shanghai yard if your bank or partner requires an independent report.

How to ask for a useful quote

Send your discharge port, preferred year/hours range, bucket or hammer needs, and whether undercarriage remaining life is critical. A serious exporter replies with the exact unit, undercarriage estimate and same-day yard video — not only a price number.
