Investing in a used rock crusher can save money, but it comes with risks. Follow these 5 essential inspection tips from Liming Heavy Industry to ensure you get a reliable machine and a great deal. 
1. Inspect the Crushing Chamber
Check the jaw plates or cone liners for wear. Uneven wear indicates poor crusher maintenance. Measure the thickness against Liming's original specs; excessive wear means immediate replacement costs.
2. Check the Bearing Temperature
Request a test run. Bearings on a rock crusher for sale should run smoothly without overheating. High temperatures can signal lubrication issues or imminent bearing failure.
3. Review the Engine and Hydraulics
Check for oil leaks, smoke, and engine hours. A full service history is ideal. For mobile crushers, test the hydraulic system for responsiveness and leaks in the drive and conveyor belts.
4. Examine the Structural Frame
Look for cracks, welds, or rust on the main chassis. A compromised frame affects stability and safety. This is a critical part of any stone crusher inspection.
5. Verify Documentation and Parts Availability
Ensure you have the manual and serial number. Check if parts for this model are still available. Choosing a reputable brand like Liming makes sourcing genuine parts easier, protecting your investment long-term.
When in doubt, consider a new Liming crusher for guaranteed performance and support.
