Used Excavator : The Complete Guide to Buying a Used Excavator
Excavators can be expensive, but purchasing a used excavator can help you save money. However, purchasing used earth-moving equipment without taking the necessary precautions and performing the necessary examinations can be costly. In the same way that you would not buy a used car without thoroughly inspecting it, you should not buy a used excavator without thoroughly researching all aspects of the machine to ensure that the value is in line with its current condition.
In this article, we will look at some of the features and functions of excavators in greater detail. In fact, we recommend that you thoroughly inspect them before purchasing a used excavator.
Check for Play/Movement in the Swing Radius
To ensure that the slew ring is operating normally, look for any play or movement that is not part of its normal operation. The hydraulic excavator housing must be tight and smooth after rotation to ensure that there is no play or abnormal movement. Examine all connections, especially those between the boom and the bucket. Check for looseness in the pins and bushings. If the connection points are loose, accuracy will be reduced. If damaged, the slew ring is one of the most expensive parts to replace.
Evaluating the Condition of Exterior Excavators
Check for dents, cracks, and bends on the machine's exterior. Parts (such as the boom and stick) that are frequently used may become warped and bent over time. This frequently generally requires the replacement of damaged parts, which can be expensive. If the stick or other machine components are dented, this may indicate that the machine was previously misused.
Checks the Excavator Hydraulics for Leaks
The presence of hydraulic leaks may also indicate abuse or degeneration. As a result, all hydraulic cylinders, hoses, and lines should be thoroughly inspected. To ensure that there is no leakage, the hydraulic pump compartment, as well as the swing bearing and slew ring, should be thoroughly inspected. If there is any leakage, it should be repaired before purchasing the machine.
A faulty or Inaccurate Hour Meter
The hour meter should be checked and authenticated to ensure that the machine has been logged with the correct number of hours. If the system is not working properly or there is reason to doubt the validity of the readout, it is always a good idea to check the control pedals. If there is a lot of wear on the pedals, it could be an indication that the reading isn't accurate.
Check for Signs of Wear and Tear on the Bucket and Attachments
When bucket teeth wear excessively, it may indicate a reduction in digging efficiency and the need for bucket replacement. Look for worn-down, half-moon-shaped teeth to see if the bucket teeth are scalloped. Despite these flaws, the bucket will most likely continue to function, albeit at a reduced efficiency, and replacement may be required in the near future.
Parts Replacement / Maintenance
Ensure that the excavator's model is researched so that parts are readily available should any of the machine's components fail and render it inoperable. It is wise to determine whether or not the manufacturer's support and maintenance will be required in the future before purchasing a model. Contact your local dealership to learn more about their parts inventory for the model you want to buy.
Check the Undercarriage
The undercarriage is one of the most important and costly components of earth-moving equipment. If possible, the current undercarriage should be examined to determine the amount and type of wear. It is critical to understand that the lifespan of an excavator undercarriage varies depending on the type installed and the application/terrain in which the excavator has been used. Wear patterns on various parts of your undercarriage can reveal a lot about how the previous owner ran and maintained the machine.
Comparing Prices
Excavators, in general, hold their value well. Although hours of use are important in determining the value of new and used excavators, other factors such as model year, attachments included, and overall condition may also be considered. Used equipment can be purchased privately or through dealerships and auction houses.
The most convenient and reliable way to find the best used excavators for sale is to search an online marketplace dedicated to buying used machinery from reputable sellers (across private, rental, dealer, and large fleets). Buying used construction equipment, on the other hand, can be a costeffective way to expand your fleet and grow your business.
