The chain ring bearing the traction force, the wear of the pin shaft must not exceed 15% of the original size, and the bending value of the chain ring pin must not exceed 10% of the diameter.
There shall be no cracks in the cast steel bumps, and the buffer springs shall not be broken or permanently deformed. The material vehicle should run smoothly. The diameter difference between the two wheels of the same wheel pair must not be greater than 2 mm. When one of the four main wheels of the same material vehicle does not contact the rail surface on the flat road, the gap must not be greater than 2 mm, otherwise it will stop immediately. Run, make repairs or adjustments. The Mine Car wheel must not have cracks, the rim wear thickness must be at least 13 mm, and the tread thickness must be at least 7 mm. The steering device is flexible and reliable, and should be flexible in both horizontal and vertical directions.
