Buy 2 hands excavator problem, buy second hand excavator and what to do if you are cheated

The most important thing about the quality of the excavator is to look at the engine, walking, arm strength are determined by the engine, the quality of the engine should be quite troublesome to test through the instrument, but other inspection methods are still available, the excavator master with high seniority is still the first, of course, the maintenance master can also be, be careful of others to deceive is what should be noted.

The speed handle arm is all straightened, and the branch car is tested, and the hydraulic pressure of the large pump is not held back.

Walk with a grapple to hold down one side to walk Don't hold the car on both sides to try the throttle to the end to see the speed The engine to see if there is any exhaust do not listen to the sound of the machine Machine maintenance is not expensive The main hydraulic pressure must be good Look at the chain Look at the big pump leakage oil Rotate and mine.

Summary. 1. Collect evidence: the other party's real name, **, address, appearance, and the name, **, address, appearance, payment voucher, chat records, written materials, introducers, etc. used in the process of contacting youDealing with civil disputes means that you hire a lawyer or only ask a lawyer to write a complaint on your behalf, obtain the defendant's identity information, bring evidence, etc., and request the court to file the case.

Dear, I'm glad to answer your <>

If you have the real identity information of the other party, you should be sued and matched. If not, call the police in time. In the case of damage caused by the sale of civil property, it may first negotiate with the other party to settle the matter and demand that the other party compensate for the losses, and if the negotiation fails, a lawsuit may be filed with the people's court with relevant evidence.

The other party doesn't negotiate with me, it's just a fool.

If you are suspected of fraud, call the police directly, and if the local public security bureau does not care, you will directly tell them to skip them and report to the next level.

I have the other party's address** ID number of the receiving account.

As long as you have something in the contract and they don't do it, call the police directly.

Collect evidence and go directly to the police and go to court to prosecute.

This is purchased by other provinces, and our local police let those who are out of town find the local police.

The contract is not regular.

None of the contracts wrote about the car.

1. Collect evidence and evidence: the other party's real name, **, address, appearance, and the name, **, address, appearance, payment vouchers, chat records, written materials, introducers, etc. used in the process of contacting you. You can also deal with this matter as a civil dispute.4 Deal with a civil dispute, that is, you hire a lawyer or only ask a lawyer to write a complaint on your behalf, and obtain the defendant's identity information, bring evidence, etc., and ask the court to file the case.

The only way you can do now is to call the police and then find the industrial and commercial department to go to his store, there is no other way.

You can only sue for this.

There is also a way to report to the Market Supervision and Administration Bureau, and request the Market Supervision and Administration Bureau to intervene in the investigation and punishment according to the results of the investigation. But your cross-provincial will be troublesome.

1. Excavator arm, observe whether there are cracks in the big arm and small arm of the excavator, traces of welding, if there are cracks, it proves that the working conditions of the machine are relatively bad before, and the machine is seriously damaged. Even if such a machine is bought, it is not easy to take care of.

2. Observe whether there are traces of bumps in each oil cylinder, if there is a bump, it proves that the machine has been seriously damaged, the oil cylinder will continue to leak oil, even if the new oil seal is replaced, it will continue to leak oil in a short time, so when buying a second-hand machine, it is also very important to check the oil cylinder.

3. Check the four-wheel belt, first observe whether the driving wheels, idlers, rollers, carrier pulleys and tracks are seriously worn. Secondly, check whether the chain is original, there is a sign on the chain, if this sign corresponds to the information of the machine, it means that the chain is original, if it does not match, it proves that the chain has been replaced, and the machine may be seriously worn, so it is necessary to buy carefully.

4. The engine is commonly known as the "heart" of the excavator, so when buying a second-hand machine, you must carefully check the engine, listen to whether the engine is noisy, whether the power is strong, whether there is a slowdown phenomenon when working, and at the same time you can also enter the system.

5. When buying a second-hand machine, check the rotating motor, observe whether the rotation is powerful, whether it makes a lot of noise when rotating, if there is noise, you need to observe which part of the noise is made, and then carefully observe whether there is a gap in the rotating chassis, and then carefully observe the distributor of the excavator, because the function of the distributor is mainly to control the action of the work, so when buying a second-hand mobile phone to test the operation, we must see whether the work of the excavator is coherent and whether there is a pause.

6. The hydraulic pump is the power element of the hydraulic system, and its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, and the oil pump in the hydraulic system provides power to the entire hydraulic system. Therefore, the inspection of the hydraulic pump is also very important, when buying a second-hand phone, you should touch the hydraulic pump with your hands, observe whether there is a feeling of shaking your hands, and then check whether the hydraulic pump has cracks, whether there is serious oil leakage, test run, and observe whether the hydraulic pump is powerful and noiseless.

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

Buying a second-hand excavator should pay attention to the following points:

1. Is there any crack in the size arm of the excavator and whether there are traces of welding? If there is a crack in Bu Pei, it proves that the machine is seriously damaged, and such a machine is not easy to take care of when it is bought, so it needs to be cautious.

2. Observe whether there are traces of collision in each oil cylinder, if there is a bump, the oil cylinder may leak, even if it is replaced with a new oil cylinder, it will continue to leak after slag dismantling in a short time.

3. Check the four wheels and observe the driving wheels and idlers.

4. Check the motor to observe whether its rotation is strong, noise conditions, etc.
