When buying a used wheel excavator, it is very important to contact a professional dealer. Check the brands offered by the dealer and their reputation. You can ask for advice among your business contacts.
You have to go to the dealer and check the machine personally. Also, ask about any support they might offer. If you are looking for a used machine, you need quality maintenance for the machine to operate safely.
As an operator, you need a long term relationship with your dealer. You have to be sure about everything and then choose the current top sellers.
1. Check the rotating ring
You need to check the killed rings for signs of damage. Swivel rings are quite expensive to repair and replace. So you don't want to make such an investment. So check the driven ring for signs of damage.
2. Look for cracks and bends
Booms and Bars: You will need to check for cracks in the weld points at the junctions that hold the boom and rod together. You should also check the weld between the stem and the spoon. If there are cracks, you need to replace the boom and rod.
Chassis: It's hard to pinpoint the importance of the chassis. You will need to inspect the case for any visible signs of damage. Talk to the dealer to review options.
3. Check for leaks
You need to check the hydraulic system of the machine before making a purchase. If the pipes are leaking or the hydraulic pump makes a strange noise, it could be a sign that something is wrong.
