Excavators have a corresponding life cycle and need necessary care in each period. As a kind of heavy machinery, if the excavator does not pay attention to maintenance in each important stage, there will be more parts that need to be repaired in case of failure than the excavator that pays attention to maintenance, and the maintenance cost will increase. If you want to extend the service life of the excavator, it is very necessary to understand the maintenance matters of the excavator in each period. This article will describe how to maintain the excavator just delivered, for reference only.
When an excavator just leaves the production plant, it should be noted that the running in of the new machine is called the running in period. For the excavator just bought back, the first thought is to put it into use as soon as possible. As a result, the excavator was overloaded, early failures occurred frequently, and the service life of the excavator was greatly reduced. However, as the parts and components of the new excavator have just been put into use, the surface is rough, the concave convex parts rub against each other during operation, and the rubbed metal debris participates in the continuous friction, so the parts and components in this period are easy to wear. If the overload operation at this time, it is easy to cause damage to parts and early failure.
Therefore, for newly purchased excavators, we should first ensure the appropriate amount of operation and do not overload operation. The working load during the running in period shall not exceed 60% of the rated working load to prevent overheating caused by continuous operation of the machine for a long time. In addition, do not start working after entering the cab of the excavator. Check the instrument panel, oil and tightness, and add grease to the lubrication points every rotation.
