Reliability Analysis of Hydraulic Components and Excavator Engine in Maintenance of Mine Heavy Equipment
Abstract
This research aims to analyze the reliability analysis of hydraulic components and excavator engine in maintenance of mine heavy equipment. In this research determined reliability and critical component replacement interval of hydraulic system and engine unit excavator. Determination critical component replacement interval of hydraulic system and engine was done by using minimal maintenance cost model. Reliability value of excavator EH 4 is the lowest compared to EH 3 and EH 5 at the time t is equal to 96 hours. Reliability value of Excavator EH 4 is 0.002, EH 5 is 0.33 and EH 3 is equal to 0.49. Component with maximum replacement interval is fuel filter Excavator EH 4 that is equal to 432 hours and component with minimum replacement interval is component Hose Pilot of excavator EH 3 that is 22398 hours
