The treatment seen has become an important approach that is used for the optimization of machinery in very demanding companies such as mining. In the specific case of Komatsu hydraulic shovels, preventive maintenance is presented as an important response to the different challenges that operate in some aggressive environments. This work focuses on the principles of continuous auscultation and data analysis to predict failures and improve operational efficiency, in light of the experience gained in my research entitled "Prediction maintenance proposal applied to hydraulic blades Komatsu».
Basic principles of predictive maintenance
The recognition of predictive maintenance in hydraulic blades must be taken into account, which involves the implementation of different sensors that help monitor important parameters in the measurement of temperatures, measurement and obviously depressions. These detectors generate real-time data that is processed to detect some models that help differentiate possible failures in the components of said machinery. This system makes it possible to intervene before a critical failure occurs, which significantly reduces unplanned downtimes and extends the service life of the machine.
Implementation in mining operations
During the application of predictive maintenance in a project in the mining regions of northern Chile, advanced sensors were installed on the hydraulic shovels to monitor certain key operating parameters. The values generated are integrated into an analytics system that helps identify minute signs of wear and potential failures.
The goal of the implementation was explicitly to reduce the meaningful form into unplanned words. This method not only improved operational activity but also helped to plan more effective conservation and utilization activities. That system allowed the different maintenance teams to address the different and complex aspects of problems proactively, helping to reduce the rate of unused and planned downtime.
One of the most notable fruits for the improvement of stability in operations and the satisfaction that the technical service had, an experiment of more comfortable and stable work. However, initial challenges had to be faced, such as the proper calibration of the sensors and the accurate interpretation of the data generated.
The initial cost of installing sensors and analytical systems can be high, but these costs are rewarded by long-term savings due to reduced downtime and costly overhauls.
The future of predictive maintenance is advancing with AI and machine learning, enhancing accuracy and identifying failure patterns that traditional methods may miss. These technologies allow for improved equipment cleaning and repairs, cutting costs. In mining, predictive maintenance for Komatsu hydraulic shovels proves crucial, optimizing machinery lifespan, reducing unplanned downtime, and improving technicians' work conditions. My research shows that constant monitoring and data analysis lead to proactive interventions, minimizing disruptions and significant financial losses. Despite initial implementation costs, the long-term benefits of predictive maintenance—including increased operational efficiency and reduced repair expenses—justify the investment, promising lasting advantages as technology evolves.
