A guide to excavator maintenance
Did you get there?
preface
It is well known that as a diggers, we spend part of our time with the excavators, and we have good excavator maintenance skills in our hands, so that we can "conquer" the construction machinery industry, extend the service life of the excavator, and achieve the maximum benefits of the excavating machine.
The excavator maintenance guide has been put together below. How many maintenance routines have you done for your loved machine?
one
Check the gold for 10 minutes
Indicators of inspection: hydraulic oil level, tightness of the shaft, gap between the bores.
Hydraulic oil level
Stop the liquid pressure level for 30 minutes to observe the level gauge, it will be lower than the L line will lead to cavitation of the pump body;
Track tightness
Tread tension , guide wheel to drag chain wheel ≤ 40mm , too tight to accelerate the weight wheel scrapped ；
The gap between the teeth
Bucket teeth gap, insert 0.5mm feeler into, loose will tear bucket ear plate;

two
Seasonal Defense
Antifreeze for Fall
The concentration of ethylene glycol should be ≥ 40% (freezing point -25C), and the pH value should be 7.5-11;
Battery maintenance
The negative electrode needs to be disconnected for more than 3 days when the power is less than 12.4V-24.7V (for models).
Air conditioning system
Replacement of drying bottle + refrigerant recovery , to prevent winter pipeline freezing ；

three
Always check it out.
Every day, check whether the solder bolt is loose, loose, or missing, and fasten it in time. Check whether the structure is cracked or deformed. When parking the excavator, pay attention to the surrounding environment, park on solid, smooth and hard ground, and don't park beside rivers, cliffs, or under hills to prevent accidents.
epilogue
The role of maintenance for excavators is self-evident, and regular maintenance and inspection can effectively reduce the occurrence of faults and extend the service life of excavators.
Of course, depending on the different aircraft models and the specific use of the excavator, the maintenance cycle and maintenance project will also vary.
