For those who operate excavators, they spend most of their time with excavators. Excavators have become a part of life. You must be good to this partner. After all, they earn money for you. If you want to extend the service life of the excavator, the most important thing is to maintain the excavator well. Only after maintenance can you have the strength to work. Here is a list of eight major maintenance of excavators. What kind of maintenance have you done for your beloved machine?
Maintenance 1: Daily maintenance is essential
You should maintain the excavator every day. There are many aspects of daily maintenance of excavators, such as butter. Then make a list of daily inspection items for everyone!
For example, check and adjust the reverse tension of the track; Check the front window washer fluid level; Check and clean the air filter element; Check and adjust the excavator air conditioner; Clean the floor in the cab; When cleaning or replacing the coolant, park the excavator on the level ground; Check and tighten the track shoe bolts; Clean the inside of the cooling system, adjust the bucket clearance of the excavator, etc. So many things need maintenance and inspection!
Maintenance 2: Inspection before engine start
Before the excavator starts construction, it is also necessary to check before starting the engine, for example, check the level of the coolant level (adding water), check whether the air filter element is blocked, check the oil level of the excavator engine, check the hydraulic oil level (adding hydraulic oil), check the fuel level of the excavator (adding fuel), check whether the horn is normal, check the lubrication of the bucket, check the water and sediment in the oil-water separator, and so on.
Maintenance 3: maintenance required every 100 hours
Normally, the excavator also needs to be maintained every 100 hours, such as: boom, stick connecting pin, boom cylinder head pin, stick cylinder head pin, stick cylinder rod end, bucket cylinder head pin, bucket cylinder rod end, bucket cylinder rod end, check the oil level in the swing mechanism box, etc.
Maintenance 4: maintenance items every 250 hours
The maintenance items that the excavator can carry out every 250 hours include: check the oil level in the final drive box of the excavator (add gear oil), check the tension of the fan belt, check the tension of the air conditioning compressor belt, check the battery electrolyte, change the oil in the engine oil pan and change the engine filter element.
Maintenance 5: maintenance items every 500 hours
The maintenance items to be carried out within 500 hours include: replacement of the fuel filter element of the excavator, inspection and cleaning of the radiator fins of the excavator, inspection of the height of the lubricating grease of the rotary pinion (with lubricating grease), replacement of the radiator fins of the oil cooler and the cooler, replacement of the hydraulic oil filter element, and replacement of the oil in the final drive box (only at 500 hours for the first time, and once every 1000 hours after) Clean the air filter elements inside and outside the excavator air conditioner system, and replace the hydraulic oil vent filter element. I don't know if you have done all the above maintenance?
Maintenance 6: maintenance items for 1000 hours
1000 hours is also a time node for excavator maintenance. The inspection and maintenance matters that should be carried out include: inspection of the oil level (return oil) of the shock absorber housing, replacement of the oil in the excavator slewing mechanism box, inspection of all fasteners of the turbocharger, inspection and replacement of the tension of the generator belt, replacement of the anti-corrosion filter element and replacement of the oil in the final drive box, etc.
Maintenance 7: 2000 hours of excavator maintenance
The maintenance of the excavator in 2000 hours includes: cleaning the filter screen of the hydraulic oil tank, checking the generator, starting motor, checking the valve clearance of the engine, checking and cleaning the turbocharger, and checking the shock absorber, etc.
Maintenance 8: Maintenance required for more than 4000 hours
The excavator shall be maintained at every stage of its life cycle, and the inspection of water pump shall be increased every 4000 hours; The maintenance of replacing hydraulic oil should be increased every 5000 hours.
Summary: Maintenance plays an important role for excavators. Excavators may have various faults during use. Regular maintenance and inspection can effectively reduce the occurrence of faults and extend the service life of excavators. Of course, the maintenance period and items will vary according to different models and the specific use of excavators.
