You Should Know Before Buying A Used Excavator
2016-02-18

Buying any kind of commercial equipment is not cheap, even when buying second hand. If you are looking to purchase a used excavator then there are certain things that you should look for before you make your purchase. After all, you need to know you are purchasing a reliable and well maintained piece of equipment. Repairs to a commercial excavator can be expensive so making sure you are investing your money wisely is important. We have put together some top tips on what inspections to do and what to look for when purchasing a used excavator.

Excavators manufactures make these machines with an approximate operating lifespan of 8,000 to 10,000 hours. So, consider buying used excavator of 2-3 years old model with only a few thousand hours on them. They are about 20-25% cheaper than a new excavator.

If your budget is lower, you might consider buying used excavator of more than 3 years old model with a concession of about 45-50% of the cost of new machine. However, they will only be useful when you have to work with them occasionally.

How to Inspect Used Excavator?

Check all moving parts - An excavator is controlled by hydraulics and uses many moving parts which can be expensive to replace or repair. It is not enough to simply look at the parts, you need to actually use the excavator and check that the following are working correctly;

Slew ring

Boom

Excavators Stick

Bucket

Leaks in the hydraulics can be a sign of misuse or degeneration as well. All cylinders, hoses and lines should be thoroughly examined. The hydraulic pump compartment should be examined for any type of leaks, as well as the swing bearing and slew ring. All leaks should be repaired before the machine is considered for purchase.

Inaccurate/inoperational hour meter

The hour meter should be checked and authenticated to ensure that the proper number of hours have been logged onto the machine. If it is not working correctly, or if there is any reason to question the validity of the reading, the control pedals can be checked. If there is a high amount of wear on the pedals, this may be a sign that the reading is not correct.

If a seller is reluctant to show you an excavator in action then you should be suspicious and reluctant to part with your money.

Check all connection points & welds - Excavators are quality pieces of equipment but it is easy to damage them if they are not properly maintained or are used incorrectly. You should ensure that you check all connection points, joins and welds for any loose fittings or cracks. Damage between the boom and the bucket can be incredibly expensive to repair especially if it requires a replacement so you need to be sure of the quality.

Check the undercarriage - If an excavator has been used incorrectly or abused by the previous owner then often the damage will be most apparent at the excavator's undercarriage. Check the undercarriage for any major dents and cracks as this could prove costly if missed. Should you find any cracks or dents then it will be a good indication of the excavator's quality and condition.

Check the hydraulics - If you don't know much about hydraulics then it is best to get a professional who does to check all the hydraulics. If you noticed any problems with the slew ring whilst testing the excavator then it is likely that the cause is related to the hydraulics of the excavator. Hydraulic hoses can often experience leaks and whilst they are relatively easy to replace, this should be reflected in the purchasing price or the current owner should have them replaced before the sale is finalised.
