When purchasing a used excavator, you can learn about factors such as the equipment’s age, working environment, and maintenance status in order to choose a suitable used excavator.
Clear requirements
Type of work: Choose the right excavator according to the work requirements. For example, for earthwork, choose an excavator with a larger working range and efficient operation; for fine work, choose a second-hand excavator equipment with precise operation.
Working time: Confirm whether the equipment is suitable for long-term continuous work. If it is a high-load work, the durability of the equipment needs to be considered.
Check the machine’s usage
Age and working hours: The machine’s working hours are the key factors in determining its degree of wear and tear.
Working environment: Understand the machine’s previous working environment.
Maintenance records: Ask the seller if there are detailed repair and maintenance records. Equipment that is regularly maintained is more reliable and reduces the risk of failure.
Check the engine and power system
Engine performance: The engine is the heart of the excavator, and the engine’s operation needs to be checked.
Cooling system: Check whether the radiator, coolant, fan, etc. are working properly. Overheating can cause engine damage.
Transmission system: Confirm the operation of the transmission system and check whether there is wear or abnormal noise on components such as gears and bearings.
Check the appearance and structure of the equipment
Body inspection: Check the appearance of the second-hand excavator machine for significant damage, rust or welding marks. Appearance damage may mean that the equipment has experienced a collision or improper use.
Hydraulic system: Check whether the hydraulic pipeline and hydraulic cylinder have oil leakage. The hydraulic system is the core component of the excavator. Oil leakage or damage will affect the performance of the machine.
Tracks and chassis: Check whether the crawler is severely worn. Excessive wear of the crawler will cause unstable operation of the machine and increase maintenance costs.
Check the electrical system
Battery and circuit: Check whether the battery is aged or damaged, whether the circuit system is normal, and ensure the equipment starts and operates stably.
Dashboard and operating system: Ensure that all control systems and instruments work properly, and the operation is simple and intuitive to avoid failures.
Test operation
Start-up test: Start the equipment and operate it for a period of time under no-load conditions to check the stability of the engine, the response of the hydraulic system, and whether the movements of each component are smooth.
Load test: Perform a load test under actual working conditions to check the performance of the equipment under load to see if there are problems such as jamming or abnormal noise.
Understand the brand and model of the equipment
Brand influence: Choosing equipment from well-known brands is often more secure, with more complete after-sales service, easier to find accessories, and higher value retention rate.
Model adaptability: Choose the right model according to your needs. Different models of excavators have different operating characteristics. Make sure the selected machine meets your work needs.
Consider purchasing channels
Formal channels: Choose reliable second-hand excavator equipment dealers or certified second-hand equipment dealers to purchase and reduce transaction risks.
Market evaluation: Check the market evaluation of second-hand excavators to understand the seller’s reputation and product quality.
Price comparison
Market price: Understand the market price of the same second-hand excavator.
Negotiation space: According to the actual condition of the equipment and the market price, negotiate a reasonable price with the seller.
Professional testing and certification
Third-party testing: If conditions permit, you can ask professionals or third-party testing agencies to conduct a comprehensive inspection of the equipment to ensure that all systems and components of the equipment are in good condition.
When purchasing a second-hand excavator, in addition to paying attention to the brand, model, usage, and maintenance records of the equipment, you can also ensure the performance and safety of the equipment through on-site inspections, test runs, and other links.
