BEFORE YOU BUY
Check the machine, not just the paint
YUANJIAN MACHINERY INTERNATIONAL TRADING LIMITED is a used excavator and construction machinery supplier in China. Discuss the actual condition of this used Caterpillar (CAT) 312D2 crawler excavator, your application and the agreed preparation scope before payment. These are requests for evidence, not completed inspection results.
Engine & working systems
Request cold start, smoke and dashboard footage, followed by hot hydraulic operation: boom, arm, bucket, travel and swing.
Fuel use & working test →Undercarriage & structure
Review the fitted travel system, pins, welds and hydraulic leakage. For tracked machines, check track shoes, rollers, sprockets and chain wear.
Swing-bearing checks →Original paint or refurbishment
Confirm the offered condition and any cosmetic or mechanical work. New paint alone does not prove a rebuild or accident-free history.
Compare purchase options →Typical work: projects that require stable crawler undercarriage performance; earthmoving, trenching, and foundation excavation; road construction, drainage, and site preparation; truck loading, quarry support, and contractor fleet work. Match the fitted configuration and actual condition to your job.
Model-specific inspection points

- engine start, idle sound, smoke condition, and dashboard display
