T/CCTAS 139-2025 Repair basic requirements for overhauled freight cars assigned to heavy-haul railways
Basic Information
Scope
Main technical content: The current condition-based maintenance model is widely used in the vehicle maintenance of the National Energy Group, achieving the overall goal of "real-time monitoring, scientific evaluation, precise repair, cost reduction, accelerated turnover, and improved transportation efficiency", and improving the reliability, availability, safety, and maintainability of vehicles. Therefore, it is necessary to establish efficient operational condition-based maintenance technical standards with the characteristics of heavy-haul railway assigned freight cars through research, effectively guide the vehicle maintenance under the condition-based maintenance model, make the vehicle maintenance work more standardized, institutionalized, and systematized, further reduce the vehicle maintenance cost, and improve the vehicle utilization efficiency.
