1. Select the excavator type
- Choose the appropriate tonnage according to the engineering requirements of earthwork, mining, municipal engineering, etc., such as small excavators below 20 tons, medium excavators of 20-30 tons, large excavators above 30 tons, etc.
2. Inspection of core components
- Check whether the engine starts smoothly, whether there is any abnormal sound or blue smoke, blue smoke may burn the engine oil.
- Check the hydraulic system and test all movements, such as bucket, arm, and rotation. Whether there is delay or shaking.
- Check the structural parts, such as the big arm, small arm, and chassis for cracks or welding repair marks.
3. Check the operating status of the excavator
- Test the operating status of the excavator on site, or observe the speed and stability of each movement of the excavator through the excavator operation video.
4. Professional agency inspection
- If you cannot judge the quality of the excavator, you can also ask a professional inspection agency to inspect the machine, which can avoid major hidden dangers.
5. Machine purchase suggestions
- Beware of low price traps: prices far below the market may hide serious faults.
- Avoid assembled machines: Equipment assembled from different parts has a short lifespan and a high failure rate.
- Verify seller information: Individual sellers need to be interviewed, and corporate sellers need to check business information
