Used excavator purchase suggestions

2025-06-13

Latest company news about Used excavator purchase suggestions

1. Select the excavator type

  • Confirm the work content and choose the appropriate excavator according to the working environment, such as a short-tail excavator for narrow space, an excavator with wide tracks for soft ground, and an amphibious excavator for the river.

 

 

2. Inspection of core components

  • Engine: Check the color of the engine oil. If it turns white, it may be mixed with water. If it turns black, it needs to be replaced.
  • Hydraulic system: Check whether the hydraulic oil is clean. If it is turbid or has metal chips, it indicates that the hydraulic pump valve is worn.
  • Observe whether there are signs of oil leakage in the hydraulic pipeline
  • Structural parts: Check the wear of the track plate, supporting roller, and supporting sprocket.

 

 

3. Dynamic test of the excavator

  • Through on-site measurement or video, test and observe whether the slewing bearing of the excavator is stable, whether there is excessive clearance or noise.

 

 

4. Professional support

  • If you cannot judge the quality of the excavator, you can also ask a professional testing agency to inspect the machine, which can avoid major hidden dangers.

 

 

5. Anti-fraud advice

  • Beware of low-price traps: prices far below the market may be scams, and the seller may not have the goods
  • Avoid assembling machines: equipment assembled from different parts has a short lifespan and may hide serious faults.
  • Verify the seller's information: individual sellers need to be interviewed, and corporate sellers need to check the business information
