Tiivistelmä
In this thesis the current situation and possibilities of mining vehicle equipment remanufacturing and rebuilding with the focus on Normet as a case study were examined. The main objectives were to create and define more affordable alternatives for equipment remanufacturing, as high prices and unfamiliarity have been among the main obstacles for such work. Defining alternatives for remanufacturing also included clarifying terms used in rebuilding and repair.
Based on research of rebuilding literature and previously conducted rebuilding status reports, development work resulted in reconditioning and custom rebuilds as more cost-effective options for remanufacturing. Reconditioning focuses on replacing the main components of the equipment, while custom rebuilds are composed of individual process and component kits.
To streamline the creation of rebuild PDM structures, a remanufacturing maxbom that has listed all the basic components and accessory options, was created for the more efficient and rapid PDM structure creation. In addition to defining other rebuild alternatives and the creation of remanufacturing maxbom, several recommendations and improvement possibilities for future rebuilding at Normet were provided. This thesis serves as a foundation for the development of more user-friendly rebuild alternatives. By offering mining and tunneling companies a well working rebuild choice instead of purchasing entirely new equipment, more environmentally friendly future in mining and tunneling can be achieved.
