Product Description
How to reduce the wear of top roller?
1. Avoid walking on the inclined ground repeatedly for a long time and suddenly turn.
If the mini excavator walk repeatedly on the inclined ground for a long time and turn suddenly, the side of the rail link will contact the side of the top roller and the guide wheel, thereby increasing the degree of wear. Therefore, walking and sudden turning in inclined areas should be avoided as far as possible. Straight line travel and large turns can effectively prevent wear and tear.
2. Avoid continuing to start the machine when top roller and track roller cannot be used normally.
If you continue to use it when top roller and track roller cannot run, it may cause the roller to wear off, and may also cause the wear of rail links. If an inoperable roller is found, it must be repaired immediately! In this way, other faults can be avoided.
3. Regularly check and tighten the bolts and nuts.
The mounting bolts of the track roller, carrier roller, sprocket, idler, track shoe, driving wheel and traveling pipe are easy to loosen due to vibration after long-term operation of the machine. For example, if the machine continues to operate when the bolts of the track shoe are loose, it will even lead to a gap between the track shoe and the bolts, which will lead to cracks in the track shoe. Moreover, the generation of clearance may also increase the bolt hole between the track and the rail link, resulting in the serious consequences that the track and the rail link must be replaced because they cannot be fastened. Therefore, track bolts and nuts should be checked and tightened regularly to reduce unnecessary maintenance costs.
