Dragline maintenance data analysis using logarithmic scatterplot
Özet
Determining maintenance priorities, one of the Important tasks of maintenance departments, can be achieved by identifying and understanding the critical fault types in mining machinery. Logarithmic Scatterplot (LS) method has been recently utilized for the treatment of maintenance data for this purpose. In the present study, maintenance data of two draglines was analyzed using LS method. Careful analysis and interpretation of the field data by LS method, throws light on prioritizing the maintenance of mechanical and electrical subsystems of draglines under study. The boom, hoist rope and attachtnents, swing, drag and hoist machineries have been identified as priority components for the mechanical subsystem. Likewise, the drag, hoist, swing and propel motor and generator sets have been identified as priority components for the electrical sub-system.
