To address the issues of elevated failure rates and reduced equipment availability for underground Load-Haul-Dump (LHD) machines, stemming from the inherent limitations of manual lubrication in harsh mining environments, this study focuses on the ACY514 LHD lubrication system. An automatic centralized lubrication system was designed based on the grease consumption-supply balance equation. Practical application has demonstrated that the designed system is viable and effective, ensuring adequate lubrication, significantly reducing operator labor intensity during maintenance, and effectively mitigating equipment failures caused by poor lubrication. Furthermore, an optimization plan for this system was proposed to enhance lubrication effectiveness and simplify maintenance procedures. The results from the optimized system’s implementation show that it not only extends the service life of key components and improves overall operational efficiency and reliability but also provides a valuable reference for the lubrication technology upgrade of similar equipment.
