How to identify a used excavator

How to identify a used excavator, analyse a few points:

1, observe the second-hand excavator size arm there is no crack, if there is a crack, it means that the machine was previously used more frequently and strongly, the machine is seriously damaged. Such a machine, even if you buy back, the life is not long.

2, observe the second-hand excavator cylinder there are no traces of bumping, if there is a bump, indicating that the machine is seriously damaged, and the cylinder will keep leaking oil, even if the new oil seal will continue to leak oil in a short period of time, so in the purchase of a second-hand machine, we must pay attention to the problem of the oil cylinder.

3, check the drive wheel, guide wheel, supporting wheel, carrier wheel and track is seriously worn, but also check the chain is not the original, the chain above will generally have a sign, if this sign and the machine information corresponds to the chain is the original, and vice versa, the machine should not be purchased.

5, check the second-hand excavator rotary motor, distributor, to see whether the rotation is strong, whether the rotation of the noise, whether it can better the action of the work. These are very critical in the purchase of a used excavator, be sure to check.

6, buy a used excavator to touch the hydraulic pump, observe whether there is no shock feeling, and then check the hydraulic pump has no cracks, whether there is a serious situation of oil leakage, test drive, observe whether the hydraulic pump is powerful, no noise.

7, check the electrical system, whether the circuits can work normally, and then enter the computer system to check the motherboard, if you enter the system can see the work of the situation, such as the number of revolutions, pressure, maintenance mode, etc., it proves that the computer board is normal.
