Buying a Used Mini Excavator: Inspection Tips

Mini excavators have grown in popularity in recent years as a result of their exceptional combination of power, size, and mobility. In the sector, there is an increasing tendency toward purchasing second-hand mini excavators rather than new ones. There is no doubt that purchasing a well-maintained old computer might be a cost-effective option. However, just as with any used machine, purchasers should inspect the compact excavator thoroughly before purchasing it.

Once you’ve decided to get a used mini excavator, you must be totally informed of the tasks you intend to carry out with it. The machine’s weight and digging depth are two of the most crucial factors to consider. With an undersized computer, you might not be able to complete the tasks you set out to do. A big machine, on the other hand, is more expensive and may have challenges with maneuverability.

Some of the most crucial things to look for before making a purchase are listed below.

Machine life expectancy: A well-maintained compact excavator has a maximum life expectancy of ten thousand hours. However, if adequate maintenance is not performed, this lifespan can easily be reduced to fewer than 8,000 hours. When looking for a used machine, aim for one that was made within the last three years and hasn’t been used for more than 2,000 hours. This will provide you the benefit of current technology as well as a long machine lifespan, as well as significant cost savings over a new model.

Visual Inspection of the Excavator: The visual inspection of a used compact excavator is the first step in the evaluation process, and it can disclose symptoms of poor maintenance and potential issue areas. Start by inspecting the machine’s body and boom for cracks, bends, and significant dents. These signals indicate that the machine’s structural integrity has been damaged. Also, remember to inspect all essential stress locations for repair welds completely. Remember that a fresh coat of paint could be a warning that major structural problems are lurking beneath the surface.

Examine the connecting points around the boom, stick, and bucket as the next vital task for you. They should be sturdy, with no movement or give in the ideal situation. It’s also crucial to check that the accompanying bushings and pins are secure. Loose bushings and pins can cause a lack of accuracy between the bucket’s real placement and the stick’s position. Check for any fractures around any of the connection points, as these might be dangerous.

Scalping has a significant impact on the cutting force of an excavator bucket. You should look closely to see if there is any scalloping between the bucket’s teeth. Any bending under the bucket suggests that the equipment has been utilized for tasks that it was not designed for. It’s best to stay away from machines that have been abused or damaged in this way.

The machine’s tracks must also be thoroughly checked, as replacement tracks can be rather costly. Tracks that are more than 50% worn should be avoided. Also look for cracks and uneven wear in the treads, as these are symptoms of more serious mechanical problems that can be costly to repair.

Look for fluids under the sprocket or on the tracks to make sure the final drive seals aren’t leaking. When inspecting the sprockets, keep in mind that in good condition, the teeth are flattened rather than pointed at the ends.

Check for significant dents, excessive wear, rust, and repairs on the undercarriage. An excavator’s undercarriage is important to its operation, therefore it is safer to avoid the machine if its undercarriage is uneven or too worn.

Operational Check of the Excavator: After completing a comprehensive visual inspection, you must conduct an operational inspection of the machine. To begin, start by turning on the excavator and simulating a few digging cycles. Extend the stick, open and close the bucket, then swing the boom to check for inaccuracy and looseness.

The next step is to inspect the track by shifting the boom to one side and anchoring it with the bucket. Lift the excavator and drive the elevated track now. The track should be able to spin easily and devoid of dry rot, missing sections, or cuts. Reverse the technique for the other track, then examine the undercarriage closely once more.

The small excavator’s backup alarm and smooth control should also be examined, which can be done by pushing the machine forward and backward, and then rotating it left and right. Rotating the house by approximately 25% of a turn can also be used to assess the machine’s play.

While you’re in the driver’s seat, you may learn a lot about the little excavator. To begin, ensure that the seat is in good working order, that it adjusts entirely, and that the seat belt is in working order. Examine the horn, lights, and gauges to ensure they are in good working order. Check the window wipers, door latches, air conditioning, and other components of enclosed cab machinery.

Request an oil sample history and machine maintenance records after all of these inspections have been completed satisfactorily. Before making a final decision, you should conduct a quick market survey to get a sense of the current prices of products from various brands.
