Second-hand excavators are suitable for excavator workers who are not so well-funded and want to start their own businesses. With your own excavator, you can make money for yourself. You have to effectively choose your own project. How to choose a good second-hand excavator is the demand of many people who buy second-hand excavators. The following will introduce the skills of buying second-hand excavators from several aspects.
1. Excavator Nameplate
When buying a second-hand excavator, the first thing to do is to check the nameplate of the equipment. See if the nameplate is in the wrong format and the steel seal is knocked out by the polishing machine. It is likely that such equipment will be changed to the year or place of production. If this happens, you need to buy carefully. If you buy a device with debt disputes, you have to bear legal duty.
2. Excavator Appearance
The appearance of excavators is important. It is worth noting that it is best not to buy equipment that has been repainted. Such equipment may be rotten equipment that has had an accident or has been damaged.
3. Excavator Pump
You should pay attention to the edge of the large pump. There is a sponge-like object on it to see if there is any damage. If it is damaged, it is necessary to ask the reason clearly. Be careful when buying.
4. Excavator Chassis
Rotate the chassis of the platform, the machine does not leak oil is worth noting. For machines under normal construction, if everything is normal, there will be no oil leakage below. If there is an oil spill, it is necessary to carefully check the cause of the oil spill. If it is an oil stain on the engine, it is possible that the engine block will crack. In serious cases, the engine may be scrapped.
When checking the chassis, one must pay attention to the angle of the motor and whether the screws outside are damaged. This will affect your later maintenance. Track shoe is a point of view when observing the site. Check whether it is original and the wear condition at this stage. If it is replaced or badly worn, you have to properly consider whether the purchase at this price is worth it. After all, such a big machine does not move often. Track shoe wear should be small.
5. Excavator Hydraulic System
Hydraulic system is a point that cannot be ignored by excavators. The state of the hydraulic pipe and distribution valve in the hydraulic system reflects whether the equipment is qualified for maintenance. The machine is not under overload construction, and the pipelines around the distribution valve will not be replaced. If the replacement frequency is fast, the hydraulic system of this equipment is problematic.
6. Excavator Engine
The engine year of the excavator is similar to the factory year. In this way, it can be distinguished whether the engine has been replaced. When checking the engine, you can turn on the machine and listen to the sound of engine speed and high speed. If there is abnormal noise, you need to think carefully when purchasing.
These are the places to pay attention to when buying second-hand excavators. I hope you can buy a good second-hand excavator.
