What You Should Know About Used Excavators
Let’s face it – excavators are pricey. This is why buying a used one can be a great way to save some money. It can, however, be just as pricey if you haven’t taken the proper precautions and or performed the proper examinations (as you’ll have to spend money on getting problems rectified). If you’re interested in buying a used excavator, here is an in-depth look at what you should know:
▪ Check for play or movement in the swing radius
It is essential to check the slew ring for any play or movement that isn’t a normal part of its operations. When the hydraulic housing is rotated, it should be tight and smooth (with no play or abnormal movement). You should also check all connection points (particularly between the stick, boom and bucket), bushings and pins for loose play.
▪ Review the condition of the exterior
You should look over the exterior of the used excavator for dents, cracks and bends. Over time, some of the parts that have been used heavily (such as the boom and stick) may experience warping and bending. Dents can be a sign that the machine has been misused by previous owners. And cracks are a sign of degeneration or misuse.
▪ Inspect the hydraulics for signs of leaks
If there are any leaks present in the hydraulic system, this can be a sign of misuse or degeneration. All cylinders, hoses and lines should be thoroughly examined to ensure that they’re in good condition. The hydraulic pump compartment, swing bearing and slew ring should also be examined for leaks. All leaks will need to be repaired.
▪ Inaccurate or in-operational hour metre
You should check and authenticate the hour metre to ensure that the proper number of hours have been logged onto the used excavator. If the metre isn’t working correctly or if there is any reason to question the validity of the reading, ensure that you check the control pedals – if there is a high amount of wear on the pedals, the reading could be incorrect.
▪ Review the bucket and attachments for wear and tear
Keep in mind that excessive wear on the teeth of the bucket could be indicative of a reduction in digging efficiency, and is often a sign that a replacement bucket is needed. The teeth should be examined to determine whether they’re scalloped, which occurs when they’ve been worn down into a half-moon shape.
▪ Review the condition of the tires
The tires are an important and an expensive component of excavators or mini excavators, so their current condition should be examined and (if possible) the number of hours they’ve done should be determined. Most standard tires have a life expectancy of at least 5000 hours. Premium tires (with a longer life expectancy) are also available for a higher price tag.
If you’ve decided that a used excavator is the best way for you to obtain one of these useful machines, we hope that the information provided above has given you a better understanding of everything you should know about them. At the end of the day, ensuring that you have taken the proper precautions and thoroughly examined the excavator will go a long way to success.
