Purchasing used excavators can be a great way to save money while still acquiring a powerful and essential piece of construction equipment. However, buying used machinery comes with its own set of challenges and risks. To ensure you make a smart investment, it’s crucial to perform a thorough inspection. In this guide, we’ll cover four proven tips for inspecting a used excavator like a pro, so you can confidently make your purchase.
A thorough visual inspection is the first step in inspecting a used excavator. By following this procedure, you can find any obvious signs of wear or damage that might point to deeper issues.
Assessing the excavator's exterior in its entirety is the first step. Search for indications of rust, scratches, and harm to the body. Give specific consideration to regions inclined to mileage, for example, the underside, which frequently endures the worst part of unpleasant landscape.
An excavator's undercarriage and tracks are crucial components. Look for cracks, excessive wear, or missing bolts in the tracks. The alignment of properly maintained tracks should be correct. The rollers, idlers, and sprockets of the undercarriage, which should be free of significant wear and tear, should be examined for damage.
Check the bucket, stick, and boom for damage or excessive wear. Check for dents, cracks, and other signs of damage. Pay close attention to the bushings and pins to check for any play or movement that might indicate wear.
Check the cylinders and hydraulic lines for any damage or leaks. Hydraulic fluid leaks are a red flag because they can indicate damaged hoses or worn seals. Check to see that the hydraulic system appears to be well-maintained and that all connections are secure.
Used excavators’s engine and hydraulic system are their most critical components. Ensuring these systems are in good working order is essential for the machine's performance and longevity.
Start the engine and listen for any unusual noises, such as knocking or excessive smoke. These could indicate internal engine problems. Check the oil level and condition, ensuring it is clean and at the proper level. Inspect the air filter and radiator for signs of dirt or damage, which could affect engine performance.
Test the hydraulic system by operating the boom, stick, and bucket. The movements should be smooth and responsive, without any jerking or hesitation. Check the hydraulic fluid level and condition, and look for signs of contamination or leaks. Properly functioning hydraulics are crucial for the excavator's performance.
Operate all control systems, including the joystick, pedals, and switches, to ensure they are functioning correctly. Test the travel and swing functions, and make sure the machine responds appropriately to all commands. Malfunctioning controls can indicate underlying issues with the excavator’s systems.
Check the electrical system by testing all lights, indicators, and warning signals. Ensure the battery is in good condition and that all electrical connections are secure. A faulty electrical system can cause significant operational problems.
Reviewing the maintenance records and documentation of a used excavator for sale can provide valuable insights into its history and condition. Well-maintained machines are likely to be more reliable and have a longer lifespan.
Request the maintenance records from the seller. Look for evidence of regular servicing, oil changes, and part replacements. Consistent maintenance indicates that the machine has been well cared for, reducing the risk of future problems.
Review any repair records to understand what issues the machine has faced in the past. Significant repairs might indicate previous problems, but they can also mean that the machine has been kept in good working condition through proper repairs.
Check the number of operating hours the excavator has accumulated. Machines with high operating hours may have more wear and tear, so it's important to consider this when evaluating the machine's overall condition. Compare the hours to similar models to gauge whether the excavator has seen excessive use.
Inquire about the previous ownership and usage of the excavator. Knowing whether it was used for heavy-duty tasks or lighter jobs can help you assess its current condition and potential future performance. Machines used for lighter tasks may have less wear and tear compared to those used in more demanding environments.
Before making a final decision, it’s crucial to perform a functional test of the used excavator for sale. This step allows you to assess the machine’s performance and identify any potential issues that might not be visible during a visual inspection.
Operate the excavator in a controlled environment to test its performance. Move the machine forward and backward, and test its turning capabilities. Ensure that the tracks or wheels move smoothly and that there are no unusual noises or vibrations.
Operate the boom, stick, and bucket to test the hydraulic functions. The movements should be smooth and responsive, with no jerking or hesitation. Test the lifting and digging capabilities to ensure the machine performs well under load.
Test the stability and balance of the excavator by operating it on different terrains and inclines. Ensure that the machine remains stable and that there are no signs of tipping or imbalance. Proper stability is crucial for safe and efficient operation.
Sit in the operator’s cab and assess the comfort and visibility. Ensure that the seat is adjustable and comfortable, and that the controls are easily accessible. Good visibility from the cab is essential for safe operation, so check that there are no obstructions.
To ensure a sound investment, used excavators must be thoroughly inspected. By performing a comprehensive visual inspection, evaluating the engine and hydraulic system, reviewing maintenance records, and conducting a functional test, you can identify potential issues and make informed decisions. Whether you're adding to your fleet or purchasing your first piece of equipment, a used excavator that has been thoroughly inspected can provide dependable performance and excellent value.
