Technical Preparation for Scheduled Preventive Maintenance of Double-Decker Rolling Stock

Abstract

The article is devoted to the study of the process of technical preparation preceding scheduled preventive maintenance of newly commissioned double-deck passenger coaches. The paper considers the main tasks and goals of technical preparation, including the step-by-step process of car repair, as well as repair planning, formation of a range of applied materials, tools, and step-by-step control of work performed during repair and maintenance. Upon identifying features and inconsistencies that arise during technical preparation for repair of double-deck coaches of a new model range, ways to solve them are proposed.The paper considers the main directions in organisation of preventive maintenance in terms of implementation of measures to integrate into the process the features associated with the specifics of the assemblies, parts and materials used in those coaches; main tasks of preparing for scheduled preventive maintenance with regard to provision of workshops, of developing forms, methods and adjusting production processes, as well as of employing small-scale mechanisation tools, and manufacturing devices to speed up the repair process. The processes of carrying out scheduled preventive maintenance are structured allowing development of a process model for repair of a double-decker coaches when they are delivered at maintenance and repair facilities.The study allows regulating and improving the efficiency of technical preparation for repair of double-deck coaches, ensuring higher quality and speed of repair work, as well as effectively assessing the real need for spare parts and materials used during the repair process, since the operation of these coaches provides for a new set of spare parts, materials and elements in comparison with single-deck analogues already manufactured.
