Excavator crawler is the key part of excavator, and its service life directly affects the work efficiency and safety of excavator. Here are some suggestions for extending the life of excavator tracks:
1.Adjust track tightness
With the increase of the working life of the excavator, the track link pins and bushings of the walking part will have a certain degree of wear, resulting in a decrease in the tightness of the track. Therefore, it is necessary to periodically adjust the tightness of the track to extend its service life. Before adjusting the track tightness, first measure the track tightness (sag) to see if it is in the appropriate range.
2.Pay attention to construction environment and soil quality
According to the difference of soil quality in different construction sites, the track tension is adjusted. For example, when the construction site is full of pebbles, the track should be adjusted slightly loose to avoid bending the track plate; When the soil is soft, the track should also be adjusted slightly loose to prevent abnormal pressure on the rail link due to the adhesion of the soil; When the ground is solid and flat, it is best to adjust the track slightly tighter to prevent the loose track from sagging too much and contact the frame and damage the frame.
3.Regular inspection and maintenance
Inspect the excavator regularly and reinforce loose bolts and nuts, such as Volvo excavator in the picture above, because the support wheel, track plate bolts, drive wheel mounting bolts, walking pipe bolts, etc. are loose due to the equipment's long working time or overload vibration.Check the lubrication points regularly to ensure adequate lubricating oil and grease, and replace according to manufacturer's recommendations.
4.Reasonable operation
In construction machinery operations should strictly abide by scientific operating norms, especially in long-term load operations to avoid repeated travel on the inclined ground or sudden steering, in order to reduce the side of the rail link and the driving wheel and the side of the guide wheel contact wear.
5.Handle exceptions in a timely manner
If it is found that the sprocket or the support wheel of the track part cannot continue to operate normally, it should be handled in time, so that not only can the abnormal damage of the track be effectively avoided, but also the accidents caused by the track problem can be avoided.
6.Establish maintenance records
It is very important to establish a maintenance record of the excavator, recording the content of each repair, the time and the details of the parts replacement in order to systematically track the maintenance history and provide references.
In short, through the implementation of the above measures, the service life of the excavator crawler can be effectively extended, and the work efficiency and safety of the excavator can be improved. At the same time, it is also necessary to pay attention to flexibly adjust the strategy and method according to the specific situation in the actual operation.
