Whether you’re a contractor, construction business owner, or heavy equipment operator, investing in an excavator can be a significant decision. Excavators are the backbone of many industries, from construction and demolition to landscaping and mining. However, with the rising costs of new machinery, many companies opt for a used excavator to maximize their budget without compromising on quality.
Buying a used excavator can be a smart financial decision, but it comes with its own set of challenges and risks. This guide will take you through the most important factors to consider when purchasing a used excavator. By the end, you’ll be well-equipped to make an informed decision that suits your operational needs and avoids potential pitfalls.
1. Define Your Needs
Before diving into the marketplace, take the time to define exactly what you need the excavator for. Different jobs require different types of excavators, and buying one that doesn’t suit your specific requirements could result in unnecessary costs or operational inefficiencies. Here are a few questions to consider:
What’s the size of the job site? Are you working in tight urban spaces or open fields? Small to mid-sized excavators are typically more maneuverable and suited for confined spaces, whereas larger excavators provide more power for larger, more open projects.
What materials will you be digging or moving? Depending on whether you're working with soil, rocks, gravel, or heavy debris, the strength and digging depth of the excavator will vary in importance.
Do you need additional attachments? Excavators are highly versatile machines, often used with attachments like buckets, hammers, and augers. If you anticipate switching between attachments regularly, ensure that the excavator has the appropriate hydraulic systems and connectors to support this.
By defining your exact needs upfront, you’ll be in a better position to focus on machines that align with your specific job requirements.
2. Check the Machine’s History
Once you’ve identified a potential excavator, the first thing you should do is check its history. The machine's service and repair history will give you valuable insight into how well it’s been maintained and how much life it has left. Ask the seller for:
Maintenance records: Consistent maintenance indicates that the excavator was cared for properly. Lack of service records or gaps in maintenance should be a red flag.
Previous usage: Try to determine what kind of work the machine was previously used for. Was it used in harsh environments, such as mining or demolition, or in less demanding applications like landscaping? Machines exposed to extreme conditions typically wear out faster.
Hours of operation: While excavator hours are similar to miles on a car, they don’t always tell the whole story. A machine that’s worked for thousands of hours in light conditions may be in better shape than one with fewer hours in a harsh environment.
The machine's history will give you a strong sense of whether it's a good investment or likely to cause problems down the line.
3. Conduct a Visual Inspection
A thorough visual inspection is essential when purchasing a used excavator. Although surface-level checks can’t tell you everything, they can help identify signs of wear, abuse, or damage. Here's what to look for:
Exterior condition: Walk around the machine and inspect for any dents, cracks, or signs of welding repairs on the boom, stick, and body. If you see any of these, ask the seller about previous accidents or repairs.
Tracks or tires: Inspect the tracks or tires for excessive wear or damage. Steel tracks should be checked for uneven wear patterns, missing pins, or signs of excessive rust. Rubber tracks should be free of deep cracks or missing tread, and the undercarriage should show no major signs of damage.
Hydraulic cylinders and hoses: Look for leaks around hydraulic cylinders, hoses, and fittings. Small leaks might indicate minor issues, but major leaks can suggest significant wear on the hydraulic system. Don’t forget to check the boom and dipper arm cylinders, as these take the brunt of the work.
Bucket: Inspect the bucket for wear and tear. Pay attention to the teeth, side panels, and overall condition. A worn bucket might need immediate replacement or repair, adding to the overall cost.
Cab condition: The state of the cab can also tell you a lot about how the excavator has been treated. Check for signs of excessive wear, such as ripped seats, non-functioning gauges, or damaged controls. A neglected cab may suggest overall poor maintenance.
4. Inspect the Engine
The heart of any excavator is its engine, and a well-maintained engine is key to its longevity and performance. When inspecting the engine, consider the following:
Start the engine: Listen for any unusual noises, such as knocking or rattling, that could indicate engine problems. If the machine struggles to start, it could be a sign of a larger issue, such as poor maintenance or mechanical problems.
Look for leaks: Inspect the engine for oil, fuel, or coolant leaks. Significant leaks could lead to costly repairs down the line.
Exhaust color: Pay attention to the color of the exhaust smoke when the engine is running. Blue smoke could indicate burning oil, while white smoke could suggest a coolant leak. Black smoke typically indicates the engine is running too rich and may have issues with the fuel injection system.
Check the oil: Examine the oil level and color. Dark, dirty oil could suggest the machine has not been properly maintained, whereas clean oil indicates regular servicing.
If you’re not confident in your ability to assess the engine, consider hiring a professional mechanic to inspect it for you. It may cost extra upfront, but it could save you from buying a machine with significant engine problems.
5. Hydraulic System Performance
Excavators rely heavily on their hydraulic systems to perform most of their tasks, so it’s important to ensure that the system is in good working order. Here’s how to check the hydraulics:
Operate the machine: Engage the boom, stick, bucket, and any attachments the machine might have. Watch for smooth movement and response time. Slow or jerky movements could indicate problems with the hydraulic system or worn-out components.
Hydraulic fluid levels: Low hydraulic fluid levels may point to leaks or neglect in maintenance. Make sure the fluid is topped up and the system is free from air bubbles.
Inspect the hydraulic pump: Check for any unusual noises coming from the hydraulic pump while it’s operating. Strange sounds can indicate wear or impending failure.
Check for leaks: Hydraulic systems operate under high pressure, so even small leaks can lead to bigger issues. Look for any signs of fluid leaking around hoses, cylinders, or fittings.
6. Assess the Undercarriage
The undercarriage of an excavator is one of the most expensive parts to repair or replace, so it’s important to pay special attention to it during your inspection. Here’s what to look for:
Tracks and rollers: Examine the tracks, rollers, and idlers for excessive wear. Tracks should have sufficient tread and no missing links or pins. Rollers should be free of dents or cracks and should rotate smoothly.
Sprockets and chains: Look for wear on the sprockets and chains. Worn sprockets or chains can lead to uneven track movement and can affect the overall performance of the excavator.
Undercarriage frame: Inspect the undercarriage frame for any signs of damage, such as cracks or welds. Damage to the frame can be a sign of improper operation or poor maintenance.
A well-maintained undercarriage is essential for the long-term performance of the machine, so don’t skip this step.
7. Test the Controls and Electronics
The controls and electronics of an excavator are vital to its operation. Make sure to test the following:
Control responsiveness: Check the controls for smooth, precise operation. They should respond instantly to input and not feel loose or sluggish. Unresponsive controls could indicate problems with the hydraulic system, electronics, or even operator abuse.
Electronics and gauges: Make sure that all gauges, lights, and electrical systems are functioning properly. Faulty gauges or warning lights that don’t turn off can be signs of bigger electrical issues that could be expensive to fix.
AC and heating systems: Depending on the climate where the machine will be operated, the air conditioning and heating systems should be tested to ensure they work properly.
8. Assess the Overall Wear and Tear
Keep in mind that used excavators will have some wear and tear, but it’s essential to differentiate between normal wear and signs of neglect or abuse. Assess whether the wear is consistent with the machine's hours of operation and age.
Signs of abuse: Excessive dents, deep scratches, or significant rust can suggest that the machine wasn’t handled properly. Pay attention to any signs of rough usage that could have resulted in major mechanical issues.
Normal wear: Look for signs of normal wear on the bucket, boom, and hydraulic lines. These areas naturally take a beating in any construction environment and are expected to show some signs of use.
9. Get a Professional Inspection
While it’s important to conduct your own inspections, bringing in a professional is always a smart move when purchasing a used excavator. A certified mechanic or technician can provide you with a detailed report on the condition of the machine and point out any potential problems you might have missed.
Many dealerships offer inspections as part of the sale, but you should also consider hiring an independent inspector for an unbiased evaluation. It may cost a bit more upfront, but it can save you from making a costly mistake.
