If the excavator is compared to a person, then the excavator's walking part is equivalent to the human leg. Therefore, the moving parts of the excavator is a very important part. We need careful maintenance to ensure its good work.
Many excavators have a misunderstanding of the misunderstanding "hydraulic excavator is mainly used for mining operations, seldom walking in long distance, no maintenance of the body of the lower part of the excavator". But when the lower moving body fails, it will cost a lot of repair costs. What's more, it will cause quite a lot of downtime. In order to reduce the operation loss and repair cost caused by the downtime, attention should be paid to the maintenance and inspection of the lower walking body.
1 after the operation, we should not only clean the cab, but also clean up the dirt on the moving parts.
Are 2 leaking sprockets, support wheels and driving wheels leaking?
Are 3 heavy wheels and sprockets unable to rotate?
Whether there are signs of loosening of 4 bolts
If one or more of the above cases are not taken in time, it will eventually lead to serious accidents, causing huge losses to your economy and construction period.
For example, a small bolt failure can not be found in time, it will damage the relevant parts or even the sprocket wheel or the grinding wheel of the supporting wheel, which will greatly increase the maintenance cost.
