Introduction

Purchasing a used crane requires meticulous planning and assessment. This guide provides insight into key factors, inspection guidelines, and evaluation of solutions from renowned brands like XCMG and SANY.

Essential Considerations

When buying a used crane, evaluate factors such as:

• Age and Usage: Assess the crane's age and total operational hours. An average crane lifespan can range from 20,000 to 50,000 hours.
• Load Capacity: Ensure the crane's capacity aligns with your project requirements, calculating for maximum loads and working radius.
• Service History: Review maintenance logs for regularity and comprehensiveness, including inspections per ASME B30 standards.
• Physical and Structural Condition: Check for signs of corrosion, fatigue in structural elements, and stress on critical components.

Inspection Guidelines

Conduct a thorough inspection including:

1. Engine and Hydraulics: Look for leakage and test functionality under load.
2. Electrical Systems: Confirm operational status of controls, sensors, and displays.
3. Brakes and Safety Systems: Test brake functionality and safety features such as limit switches and overload protection.
4. Structural Integrity: Inspect welds, booms, and counterweights for stability and integrity.
