Maintenance
When maintaining axles in construction machinery, the "prevention-first, enforced maintenance" principle must be followed. By carrying out regular cleaning, scheduled lubrication, tightening, and component inspections, latent problems can be identified and resolved promptly, stopping small defects from evolving into major damages—including severe incidents like bearing seizures leading to gear teeth wear or axle fractures. Recommendations include developing a tailored maintenance schedule according to how often the equipment is used and its working conditions, and prioritizing OEM components to ensure consistent axle performance and prolong the equipment’s lifespan.
