What should I look for when buying a used excavator?

Introduction

Purchasing a used excavator can be a cost-effective solution for expanding your fleet or starting a new project. However, ensuring that the machine is in good condition and is capable of delivering reliable performance is crucial. This guide provides a comprehensive checklist for evaluating used excavators, with a focus on solutions from XCMG and SANY, two prominent manufacturers in the industry.

Key Considerations When Buying a Used Excavator

1. Physical Condition

• Inspect the undercarriage, tracks, and rollers for wear and damage.
• Check hydraulic cylinders and lines for leaks.
• Examine boom and stick for cracks or welds indicating repairs.

2. Operational Checks

• Start the engine and listen for unusual noises.
• Test all control functions for smoothness and responsiveness.
• Verify the functionality of attachments and quick couplers.

3. Maintenance Records

• Review logs for regular maintenance and any past repairs.
• Ensure oil and filter changes were conducted according to schedule.
• Cross-reference hours of operation with expected maintenance intervals.

4. Hours of Use

Assess the total hours of operation. An average of 1,500–2,000 hours per year is typical for excavators. Machines over 10,000 hours may require more frequent maintenance, driving up overall costs.

Evaluating Used XCMG and SANY Excavators

XCMG Excavators

• Review model-specific common issues based on reports.
• XCMG models are known for their durability; verify efficiency ratings.

SANY Excavators

• Inspect electronic components for SANY-specific software integration.
• SANY models are lauded for their hydraulic systems; test thoroughly.

Conclusion

When purchasing a used excavator, a thorough examination of its physical and operational status is important. Special attention should be given to the maintenance records and operational hours to predict future performance issues. Whether choosing XCMG or SANY, understanding model-specific traits and common wear points can ensure a sound investment.
