Excavators are valuable and expensive equipment, which needs attention and maintenance. It can help to avoid downtime and save money in future. There are some maintenance routines, which are simple, but can be costly and time consuming to resolve.
General Daily Maintenance
- Clean the exteriors regularly using high pressure water
- Clean cabin frequently
- Safety messages need to be visible, every time and not hidden by dust
- Handholds and steps need to be checked (loose or broken)
- Regularly clean the AC filter or dust buildup can decrease performance and shorten its life
Recommendation checklist of excavator maintenance
Hydraulic & engine oil levels
These need to be regularly checked and added, whenever needed. Every excavator differs a little, so check your manual to find out how often to change. In addition, look at the oil quality to be used to replace because wrong quality can cause hydraulic failures.
Service manuals are a must and must be stored in a handy place. Certainly, you can buy manuals from http://www.repairloader.com/ for every kind of industrial vehicles.
Use right kind of oil
Using low quality oil causes an array of issues. Hi-grade oils are formulated specially to prevent oxidative and thermal breakdown. It enhances soot related wear and viscosity features.
Hydraulic systems are capable to deal with certain tolerance levels, so improper oil change or contamination can lead to hydraulic collapse. Cheap oil often includes additives, which will stop working, when exposed to high duty cycles.
It is recommended to have an oil sample program conducted regularly to identify contaminants.
Water & fuel separator
Modern excavators are equipped with fuel filter, which has water separator to eliminate water. Daily inspection for proper draining process is needed.
Just like oil, fuel needs to be of correct type and high quality. Make sure to have a fuel technician check for proper additives in the fuel to avert the development of algae and organisms. Check the fuel tank vent because it gets clogged easily, while operating in dusty conditions. This can lead to over-exertion on fuel pump, while delivering the fuel.
Inspection of cooling system
Heat shields and radiator insulation in the engines need to be in their correct place and in case of wear be replaced. Oil or coolant leakages can build dust and debris on the surface of heat exchanger, which can reduce its performance.
Well greased pivot points
Make sure to lubricate every attachment frequently using premium quality grease. It includes dipper, boom, buckets, busting, and pins. Sufficient greasing is good but over-greasing causes environmental hazards. It can be messy and not to forget increase fire risk.
Bucket & attachments
Check buckets and other attachments daily for wear and cracks. Teeth of the bucket will wear off quickly, if it is applied for heavy cutting work daily.
If track is too tight then it triggers premature wear or breakage and if it is too loose causes poor maneuvering and finally de-tracking. Properly adjusted track increases service lifespan and alleviates the wear on tracks and its parts.
Regular oil changes and cleaning is needed for gearboxes, which are most probably overlooked.
Check for leakages
Monitor the fluid levels daily to keep track of leakages. Inspect cooling system, swing drive, and hydraulic system. If leaks get identified then take care of it instantly.
Spending some time on regular inspection and maintenance will allow you save significantly in due course.
