What should I pay attention to when buying a second-hand excavator
In the field of engineering machinery, second-hand excavators have become the first choice for many buyers due to their high cost performance and fast return on investment. However, there are certain risks in purchasing second-hand equipment. How to avoid traps? This article combines popular topics and industry experience on the entire network for the past 10 days to sort out the core precautions for purchasing second-hand excavators.
1. Analysis of the current market status of second-hand excavators (popular data in the past 10 days)
| Popular Platforms | Average daily search volume | Mainstream price range | Top 3 Popular Brands |
|---|---|---|---|
| A second-hand trading platform | 5,200+ times | 150,000-350,000 yuan | Komatsu, Carter, Trinity |
| Construction Machinery Forum | 3,800+ times | 100,000-300,000 yuan | Hitachi, XCMG, Volvo |
| Short video platform | 120,000+ views | 200,000-500,000 yuan | Shengang, Doushan, Liugong |
2. Six core indicators for purchasing second-hand excavators
1. Check basic equipment information
| Check items | Qualification criteria | Risk warning |
|---|---|---|
| Factory year | Equipment recommended within 5 years | Be careful to choose for more than 8 years |
| Working hours | ≤8000 hours | The instrument may be tampered with |
| Nameplate integrity | Clear engine/frame number | Information blur may be assembler |
2. Key points for detecting key components
| Part Name | Detection method | Repair cost reference |
|---|---|---|
| engine | Cold start test, observation of exhaust color | Overhaul 30,000-80,000 yuan |
| Hydraulic system | Test the response speed of each operation | Pump and valve repair 10,000-50,000 yuan |
| Walking device | Check track wear and drive gear tooth shape | Replacement costs 20,000-60,000 yuan |
3. Guide to avoid pitfalls in the transaction process
1. Certificate Review List
| Required Documents | Check points | Risk of missing |
|---|---|---|
| Original invoice | Check the consistency of equipment information | Unable to prove the legal source |
| Certificate of conformity | Check the anti-counterfeiting mark | Impact subsequent resale |
| Environmental protection list | Confirm emission standards | Probably faced restriction |
2. Seven-step method of field test machine
① Static inspection: Appearance rust, weld cracks, etc.
② Start the test: observe the instrument alarm indicator
③ Hydraulic test: Whether each oil cylinder is leaking internally
④ Rotary test: rotary motor abnormal noise detection
⑤ Walking test: Assessment of degree of deviation
⑥ Bucket test: judgment of excavation force attenuation
⑦ Oil detection: Observe the content of metal debris
4. Warning of recent hot cases
According to the latest notice from the Construction Machinery Association:
- Five refurbished machines were seized in a certain province and assembled with scrapped parts
- A certain platform exposed the "hour modifier" to tamper with instrument data
- Many disputes involved "yin and yang contracts", with a price difference of more than 40%
5. Professional advice
1. Priority is given to certified second-hand mobile phones with warranty
2. It is recommended to entrust a third-party testing agency (the cost is about 2,000-5,000 yuan)
3. Keep a complete transaction communication record
4. Beware of "bad-picking" opportunities that are significantly lower than the market price
Through systematic inspection procedures and standardized trading procedures, the risk of purchasing second-hand excavators can be significantly reduced. It is recommended that buyers make rational decisions based on their own engineering needs, consider the equipment residual value, maintenance cost and use cycle.
