2. Whether the wheel runout and rim wear exceed the limit; Whether the fastening bolts of the wheels are loose;
3. Deformation of the carriage and welding of the bottom beam;
4. Check whether there are cracks and wear on the contact head, and whether the hooks, rings, and pins of the connecting device are complete and complete.
5. Mining cars with serious defects found during daily maintenance inspections should be sent to a repair workshop for repair.
Regular inspection:
1. Identify the technical status of all mining vehicles operating;
2. Determine whether the carriage and its components of each mining car can continue to be used;
