For people who drive excavators, most of the time with the excavator, excavators have become part of life, that must be a little better for this partner,want to extend the life of the excavator, the most important thing is to maintain the excavator, the following for you to organize a maintenance list of excavators.
1. Daily maintenance
Every day of a period of time, you have to carry out maintenance on the excavator, excavator daily maintenance of many links, such as more familiar with the grease, the following is the list of daily check things.
For example: checking and adjust the track tension, checking the front window cleaning fluid level, checking and cleaning the air filter, checking and adjusting the excavator air conditioning, cleaning the cab floor, when cleaning or replacing the coolant, the excavator should be parked on a level surface, checking and tightening the track plate bolts, cleaning the inside of the cooling system, adjusting the excavator bucket clearance.
2. Inspection before starting the engine
Before the excavator is going to start construction, it is also necessary to check before starting the engine, such as checking the height of the height of the coolant level position(add), checking the level of hydraulic oil(add hydraulic oil), checking the level of the excavator fuel oil(add fuel), checking the water and sediments in the oil-water separator.
3. Maintenance required every 100 hours
Normal excavator every 100 hour also need to carry out maintenance, such as: moving arm, bucket rod connecting pin, moving arm cylinder head pin, bucket cylinder head pin, bucket cylinder rod end, bucket cylinder head pin, bucket cylinder rod end, check the oil level in the slewing mechanism box and so on.
4. Maintenance items every 250 hours
Maintenance items that can be carried out every 250 hours include: checking the oil level in the final drive box of the excavator(add gear oil), checking the tension of the fan belt, checking the tension of the air conditioning compressor belt, checking the battery electrolyte, replacing the oil in the engine oil pan, and replacing the engine filter.
5. Maintenance items every 500 hours
Maintenance items to be carried out at 500 hours include: replacement of the excavator fuel filter, checking and cleaning of the excavator radiator fins, checking the height of the slewing pinion grease(adding grease), oil cooler fins and condensation fins, replacement of the hydraulic oil filter, replacement of the oil in the final drive case(only for the first time at 500 hours, and once every 1000 hours thereafter), cleaning of the air-conditioning system of the excavator, replacement of the internal and external air filter, replacement of the oil in the engine oil pan, and replacement of the oil in the engine air-conditioning compressor belt internal and external air filters, replacement of hydraulic oil vent filter.
6. 1000-hour maintenance program
The 1000 hours is also a time point for maintenance of the excavator, and the maintenance items that should be carried out are: checking the oil level of the vibration damping casing(oil return), changing the oil in the excavator’s slewing mechanism box, checking all the fasteners of the turbocharger, checking and replacing the tension of the generator belt, replacing the corrosion-resistant filter element, and replacing the oil in the transmission box.
7. Excavator maintenance at 2000-hours
Maintenance of the excavator at 2000 hours includes: cleaning of the hydraulic tank screen, checking of the generator, starter motor, checking of the engine valve lash, checking and cleaning of the turbocharger, and checking of the shock absorbers.
8. 4000 hours and above need to carry out maintenance
Excavators should be maintained at every stage of the life cycle, every 4000 hours need to increase the maintenance of hydraulic oil replacement.
Summarize: maintenance for excavators play a role in self-evident, excavators in the use of the process will appear a variety of faults, frequent maintenance and inspection can effectively reduce the failure to occur, extend the life of the excavator. Of course, according to different models and excavation sister specific use, maintenance cycle and maintenance projects will be different.
