Daily inspection of track shoes is the basis of maintenance. Before and after each operation, it is necessary to check whether the anti-slip patterns on the surface of the track shoes are excessively worn. If the patterns become shallow, the anti-slip effect will be reduced, and the track shoes need to be replaced in time. At the same time, check whether the connecting pins between the track shoes are loose. If pin displacement is found, re-tighten them to prevent the track shoes from falling off during operation.
The maintenance of the crawler tensioning device cannot be ignored. It is necessary to regularly check the hydraulic oil level of the tensioning cylinder. If the oil level is insufficient, the crawler tension will decrease, which affects the stability of the rig's movement, and hydraulic oil needs to be added in time. In addition, check whether the tension spring is deformed or broken. If the spring fails, the crawler cannot maintain proper tension, and new springs need to be replaced to ensure the normal operation of the device.
The maintenance of crawler drive wheels and guide wheels is also crucial. After the operation, clean the soil and gravel in the tooth grooves of the drive wheels and guide wheels. Long-term accumulation of these impurities will accelerate the wear of the wheel teeth. At the same time, check the lubrication of the wheel axles. If lubrication is insufficient, the wheel axles will rotate unsmoothly. It is necessary to apply special lubricating oil regularly to ensure the smooth operation of the drive wheels and guide wheels, and extend the overall service life of the crawler components.
