Buying a Used Excavator: What to Inspect
Used excavators can save you a great deal of money, since you'll save up to 50% or more off the original purchase price. But it's not worth it if you end
up with a lemon and end up shelling many more pounds simply paying for maintenance and repairs. So what should you look for when you find used
excavators for sale?
Of course, you'll first look at the papers to answer a few basic, preliminary questions, such as, when was the excavator manufactured, and when was it
last serviced? But, after that, you'll want to look at the used excavator itself. First, perform a visual physical inspection. As you inspect the various parts
of the excavator, you'll want to ask yourself whether you see any warning signs that could indicate poor performance in the future.
Look at the engine. Do you see any soot or oil leakage? These signs could potentially indicate a lack of engine maintenance, which could lead to
horrifically expensive repairs in the future, requiring a complete overhaul of the engine. Also, take a look at the cooling systems; failure here could also
damage the engine. Are the fans tight, and is the system free of debris that could wreak havoc in the wrong places? And take a look at the battery,
noting any signs of corrosion.
Look at the cab, stick, boom, and bucket. Are there any signs of major damage? While scratches are to be expected in used excavators, you'll want to
watch out for welding patches or anything bent or twisted out of shape. This might indicate that the excavator was made to perform some pretty rough
work in the past. Also check out the pivot points, most notably, the one connecting the boom to the body. They should be tight, as slackness could
indicate the need for replacement in the near future.
Finally, look at the track and undercarriage. While a used excavator will certainly have seen some minor wear and tear, you'll want to see if any of the
metal plates are actually broken or cracked. Tracks can be replaced, but the amount of wear you see could give yo
