Used Excavator & Bulldozer Inspection in China | Refurbished Equipment Quality Control
Buying a used excavator or bulldozer in China, especially from refurbishment markets like Shanghai, involves significant risk. Many machines are repainted and refurbished, making them look new while hiding serious mechanical or structural problems.
A professional heavy equipment inspection service helps buyers identify hidden defects, evaluate real condition, and avoid costly mistakes.
1. Key Risks of Refurbished Machinery
Cosmetic refurbishment: Fresh paint may hide cracks, leaks, or previous damage
Large price differences: Similar machines with very different real conditions
Hidden mechanical issues: Engine, hydraulic, or structural problems not visible externally
High repair costs: Undetected faults can lead to expensive downtime
2. Core Inspection Checklist
Structure & Appearance
Check frame, boom, and chassis for cracks, weld repairs, deformation
Identify repainting signs and hidden damage areas
Engine & Hydraulic System
Cold start test and abnormal noise check
Inspect oil leaks, exhaust smoke, and engine stability
Test hydraulic system for smooth operation and pressure performance
Undercarriage
Track wear, rollers, idlers condition
Alignment and overall wear level (high-cost components)
Functional Test
Bucket / blade operation performance
Control responsiveness and braking system
Cooling system and overheating check
3. Professional Inspection Focus
A qualified used machinery inspection should include:
On-site functional testing under real working conditions
Identification of refurbishment vs original condition
Evaluation of key components lifespan (engine, hydraulics, undercarriage)
Verification of serial number and basic machine data
4. Final Assessment
Machines are evaluated based on:
Structural condition (no major damage)
Mechanical performance (stable and functional)
Leakage and wear level
Overall refurbishment quality vs real condition
A detailed inspection report helps buyers clearly understand actual machine condition vs asking price.
