As a key component of the excavator walking system, the performance of the excavator chain rail directly affects the stability and work efficiency of the excavator. In order to ensure the normal operation of excavators and extend the service life of chain rails, the following are some maintenance techniques for excavator chain rails:

1、 Daily inspection and cleaning

Daily check:

After the end of each day's work, a comprehensive inspection of the excavator chain rail should be conducted, including the wear of components such as chain rail joints, support wheels, idler wheels, guide wheels, and drive wheels.

Check for cracks, deformations, or severe wear on the chain rail joints, as well as loose or missing bolts.

Observe whether the rotation of the supporting wheel, sprocket wheel, and guide wheel is flexible, and whether there is any abnormal noise or jamming phenomenon.

Cleaning foreign objects:

During the operation of excavators, foreign objects such as soil and gravel are prone to adhere to the chain track. These foreign objects not only increase the wear of the chain rail, but may also affect the normal operation of the walking system.

Therefore, foreign objects on the chain track should be regularly cleaned to maintain its cleanliness. Vibration method or auxiliary tools can be used for cleaning, and if necessary, cleaning equipment can be used for comprehensive cleaning.

2、 Lubrication and adjustment

Lubrication and maintenance:

The excavator walking motor, reducer, supporting wheel, and sprocket wheel all require gear oil lubrication inside. The oil level and quality of lubricating oil should be checked regularly, and lubricating oil should be replenished or replaced in a timely manner.

Note that different components may have different requirements for lubricating oil, and the appropriate lubricating oil should be strictly selected according to the manufacturer's recommendations.

Adjust the tension of the track:

The tension of the tracks has a significant impact on the walking performance of excavators and the wear of the chain rails. Excessive tension can lead to early wear of chain rail joints, gear rings, and guide wheels; If the tension is too loose, it may cause the track to loosen, affecting the stability of walking.

Therefore, the tension of the track should be adjusted in a timely manner according to the different construction road conditions to maintain it in good condition.

3、 Wear monitoring and replacement

Wear monitoring:

Regularly inspect the wear of components such as chain rail joints, supporting wheels, and sprocket wheels. Measurement tools can be used to quantitatively evaluate the wear amount, in order to promptly identify problems and take measures.

Pay attention to whether there are signs of cracks, deformation, or severe wear on the chain rail joint, as well as whether the bearings of the supporting wheel, supporting wheel, and guide wheel are worn or damaged.

Timely replacement:

For components such as severely worn chain rail links, supporting wheels, and sprocket wheels, they should be replaced in a timely manner. When replacing, new parts with the same specifications and materials as the original components should be selected to ensure their performance and quality.

At the same time, attention should be paid to the installation and adjustment work during the replacement process to ensure that the new components can be installed correctly and perform well.

4、 Precautions for operation and maintenance

Correct operation:

During operation, the excavator should avoid walking on sloping ground for a long time or sudden turning to reduce lateral wear of the chain rail.

Keep the excavator running smoothly and avoid violent operations such as sudden acceleration and braking to reduce the impact wear of the chain rail.

Regular maintenance:

Develop a reasonable maintenance plan and regularly maintain the excavator chain rail. This includes tasks such as cleaning, lubrication, adjusting tension, and checking for wear and tear.
