Mechanically sound · cosmetic wear disclosed. Sourced from 保定市, China. 16 current photos available; walkaround video and extra angles can be recorded on inquiry.
We do not list specifications we have not personally cross-checked against the Doosan DH420LC7 OEM brochure for this exact variant. On your inquiry, we send the complete spec sheet (engine power / hydraulic flow / dimensions / dig reach / travel speed / fuel consumption) along with the 150-point inspection report.
We grade by measured fact, not by hope. The bars show our inspector's estimate of remaining service life per major system. Detailed wear photos and OEM-tool readouts are in the inspection report.
The timeline below traces this unit’s known service events. Where source-yard records are incomplete, we reconstruct typical service intervals based on hour count — and disclose this transparently.
First major service interval — engine oil, hydraulic filter, fuel filter replacement.
Mid-life service — coolant flush, final drive oil, swing gear lubrication.
Routine service — air filter, fuel filter, cabin filter, hydraulic oil sample analysis.
ExcaYard 150-point pre-export inspection — engine compression, hydraulic cycle test, undercarriage measurement, ECM data extraction.
The inspection note is shared on inquiry. Major findings, visible wear, current photo set, and any requested extra angles are reviewed before payment.
Some exporters quote low CIF then add discovery fees, doc fees, handling fees, lashing surcharges. Our CIF is the total — only port-side destination charges (controlled by your local broker, not us) are extra.
