“…In this sense, this study carried out a comprehensive reliability assessment on individual components of draglines and discussed preventive component replacements in a financial manner. In the literature, much research has been carried out on the reliability and maintenance of mining machineries, such as load-haul-dump [5][6][7][8][9][10][11][12][13][14], shovel [15][16][17][18][19], longwall shearer [20][21][22][23], drilling equipment [24][25][26][27][28], and draglines [29][30][31]. There are limited amounts of research for dragline reliability and maintenance.…”

Reliability-based maintenance policies allow qualitative and quantitative evaluation of system downtimes via revealing main causes of breakdowns and discussing required preventive activities against failures. Application of preventive maintenance is especially important for mining machineries since production is highly affected from machinery breakdowns. Overburden stripping operations are one of the integral parts in surface coal mine productions. Draglines are extensively utilized in overburden stripping operations and they achieve earthmoving activities with bucket capacities up to 168 m 3 . The massive structure and operational severity of these machines increase the importance of performance awareness for individual working components. Research on draglines is rarely observed in the literature and maintenance studies for these earthmovers have been generally ignored. On this basis, this paper offered a comprehensive reliability assessment for two draglines currently operating in the Tunçbilek coal mine and discussed preventive replacement for wear-out components of the draglines considering cost factors.

“…Low levels of reliability mean more accidental failures on the production system, leading to low availability. A machine has an inherent reliability created at the design stage; thus, machine reliability studies are necessary for equipment design, modification and quality control during manufacturing, field trials and life testing (Samanta, 2001).…”

Summary The scope of this study is to review reliability, availability and maintainability (RAM) analysis in the food industry and aims to identify the critical points of the production systems that should be improved by the operational performance and the maintenance effectiveness. RAM is an engineering tool that addresses operations and safety issues of production lines and aims to identify areas within the system or process where significant improvement can be achieved. Food production lines consist of several machines supplied with a common transfer mechanism and control system that have different failure modes. When a random failure occurs, the failed machine stops and forces most of the line upstream of the failure to operate without processing, whereas the material (raw, intermediate or end‐product) of the line downstream may have to be scrapped because of quality deterioration during the stoppage. The negative failure impact is the drop of line reliability and production rate.

“…A machine has an inherent reliability created at the design stage. So machine reliability study is necessary for equipment design, modification, and quality control during manufacturing, field trials and life testing, etc [5]. Before the analyzing the failure data, the overall system is better to be classified into subsystems so that the failures can be categorized.…”
