For excavators, the “four wheels and one belt” of supporting wheel, chain wheel, guide wheel, driving wheel and track are the core components to ensure their efficient and stable operation. So, how much do you know about the maintenance points of these key components? Maintenance points of supporting wheel: It is important to regularly check the status of the fixing bolts of the supporting wheel. Once you find signs of loosening or breaking, you should take immediate measures to tighten or replace them to ensure that the balance and stability of the excavator will not be affected. Guidelines for maintenance of the pallet sprocket: Excessive wear or looseness of the pallet sprocket will directly affect the normal operation of the track. Therefore, during routine maintenance, special attention needs to be paid to the wear of the pallet sprocket, and timely adjustment or replacement should be carried out in order to avoid the occurrence of potential failures. Guide wheel maintenance recommendations: The wear of guide wheel should not be neglected, which is directly related to the strength of track guidance control ability. Regularly checking the wear state of the guide wheel and replacing it when necessary is the key to guaranteeing the precise operation of the excavator. Drive wheel maintenance precautions: The degree of wear of the drive teeth is an important factor affecting the driving efficiency of the excavator. Therefore, the wear condition of gears and racks need to be checked regularly and replaced as soon as excessive wear is found to ensure strong driving power of the excavator.
A full guide to track maintenance: Wear check: Regularly check the wear of the tracks to ensure that the track spacers, sprockets and drive teeth are all in good condition. Tightness adjustment: Maintaining proper chain track tightness is the basis for ensuring the normal operation of the tracks, and over-tightening or over-loosening may cause failure. Cleaning of debris: Remove mud, stones and other debris on the tracks in time to prevent them from damaging the tracks or jamming the tracks and affecting the normal operation of the excavator. Replacement and maintenance: When the tracks are worn out or malfunction, they should be replaced or repaired in time to ensure the continuous and efficient operation of the excavator. To summarize, mastering the maintenance points of “four wheels and one belt” is crucial to ensure the stable operation of the excavator. Only by doing a good job of daily maintenance can we ensure that the excavator always maintains the best condition in the complex and changing operating environment.
