How to reduce the crawler wear of excavators when they walk?
The walking part of excavator is composed of supporting sprocket, supporting wheel, driving wheel and rail chain. When it runs for a certain time, these parts will be worn to a certain extent. However, if the idea of daily maintenance, as long as a little time spent on proper maintenance, can avoid the future "excavator leg modification". Save considerable maintenance funds for you, and can also avoid delays caused by maintenance.
One: If we repeatedly walk on the inclined ground for a long time and turn suddenly, the side of the rail chain will contact with the side of the driving wheel and the guide wheel, thus increasing the wear degree. Therefore, walking and sudden turning should be avoided as far as possible in inclined zones. Linear travel and large turning can prevent wear and tear well.
2. If some supporting sprockets and supporting wheels continue to be used when they are unable to operate, it may lead to wheel grinding deviation, and may also cause the wear of rail chains. If you find a roller that can't work, it needs to be repaired immediately! In this way, other faults can be avoided.
Thirdly, supporting wheel, supporting sprocket wheel installation bolt, caterpillar plate bolt, driving wheel installation bolt, walking piping bolt, etc. are easy to loosen due to vibration after long working time. For example, if the crawler plate bolt is loosened and the machine continues to operate, it will even lead to the gap between the crawler plate and the bolt, which will lead to the crack of the crawler plate. Moreover, the gap may also increase the bolt holes between the track and the rail chain, resulting in the serious consequences of the failure to tighten and the need to replace the track and rail chain joints. Therefore, bolts and nuts should be regularly inspected and tightened to reduce unnecessary maintenance costs.
