Excavator maintenance and repair costs are not low; annual maintenance or repairs alone can amount to a significant sum. However, compared to purchasing a new excavator, the cost of maintenance and repair is negligible. Properly maintaining your excavator extends its lifespan and saves you money. Understanding some basic excavator maintenance and repair knowledge will ensure your excavator receives the best possible care.
I: Choosing the Right Oil
There are many types of oils available for excavators, including hydraulic oil, gear oil, diesel engine oil, lubricating oil, and brake fluid.
Different types of oil have different uses, and choosing the right oil for the intended purpose is generally understood.
However, even within the same type of oil, there are many different grades.
Different brands and models are used in different scenarios.
Sometimes, the oil grade needs to be selected based on the ambient temperature.
For example, when choosing engine oil.
At high temperatures… When the temperature is high, choose a high-viscosity oil.
When the temperature is low, choose a low-viscosity oil.
A better brand of oil does not necessarily mean it will be better for your equipment.
Using the wrong type of oil will significantly reduce its effectiveness.
Choosing the most suitable oil is the best oil.
II: Frequency and Content of Maintenance
Cars need regular maintenance to extend their lifespan.
The same applies to excavators; they also need regular maintenance.
However, more frequent maintenance for excavators is not necessarily better.
Frequent maintenance will result in higher costs.
According to… Excavators need regular maintenance to extend their lifespan and save costs.
Main maintenance is required at various stages, including 100H, 250H, 500H, 1000H, 2000H, and over 4000H.
Shorter time periods require fewer maintenance items, while longer time periods require more.
There is a lot of information about maintenance items at different time periods; you can search for relevant materials to learn more immediately.
Three: Aspects to Note During Daily Use
For newly acquired excavators, all parts need to be checked before operation. Fill with oil.
During the first week of operation, regularly check the equipment’s lubrication.
For excavators that have been used for some time:
After each operation, frequently clean and wipe the equipment.
This keeps the equipment clean and allows you to check its condition during cleaning.
After the equipment has finished operating, thoroughly check all anchor bolts, bearing seat bolts, etc., for any looseness.
During equipment operation, pay close attention to the running status of all motors.
Monitor the mechanical transmission, braking system, control system, cooling fan, lighting, and signals for any abnormalities.
