As of September 5, the Suning Branch of Railway Equipment Company has completed condition-based maintenance for over 30,000 vehicles this year, with 29,146 vehicles undergoing Z1-condition-based maintenance, accounting for 83.3% of the annual target and 1,154 vehicles receiving on-site maintenance. These efforts continue to drive the advancement of condition-based maintenance work, with robust support for the company’s integrated operations.
In 2024, the Suning Branch emphasized on the core task of “expanding and strengthening the main responsibilities and business, and promoting comprehensive reform in maintenance processes and systems”, and focused on the goal of “building a first-class intelligent railway equipment maintenance base in an all-round way”. By summarizing production experiences from the Huanghua Port maintenance and preparation line, the branch has improved its condition-based maintenance capabilities to act as a “testing ground” for the company’s maintenance reform.
Since August, the Suning Branch has adhered to the new positioning of Z1-condition-based maintenance and new standards of vehicle detention as well as overhaul for maintenance, with emphasis on fault-driven principles and goals of centrally addressing all vehicle malfunctions. The branch has implemented overhaul strategies to ensure the company’s transportation safety. Furthermore, it balanced the relationship between transportation and maintenance production, adjusted and optimized production processes with focusing on the key tasks of impounding vehicles for maintenance as well as conventional maintenance work to achieve early success in wheel tread wear. Vehicle detention is the prerequisite and foundation of maintenance work. The branch made full use of the HCCBM and HMIS systems to thoroughly follow the overall condition of vehicle wheel tread wear in the running trains and coordinated train arrival times with the railway transportation organization to ensure that vehicle detention was prepared for maintenance. In the repairing phase, the company optimized the allocation of on-site maintenance personnel, implemented 24-hour shifts, and flexibly adjusted repairing times based on train schedules. Despite adverse factors regarding heavy wheel replacement workloads, the branch developed repairing strategies and safety precautions in advance, reinforced standardized operations for wheel replacement teams, and strengthened safety supervision. These efforts have eliminated the safety risks associated with running trains with worn wheels, providing robust support for the safe and high-quality operation of railway freight cars.
