CCTV News: According to the China Railway WeChat official account, on December 26, the development of a new generation of large-scale railway track maintenance machinery and equipment made important progress. The first batch of equipment such as continuous traveling tamping stabilizers and track snow removal vehicles rolled off the assembly line in Kunming. , and will be trialled in Kunming, Beijing, and Jinan Bureau Group Companies in the near future. This marks that my country's large-scale railway track maintenance machinery and equipment has entered a new stage of development, creating conditions for promoting mechanized road maintenance of public works to a more reliable, efficient and higher level.

The relevant person in charge of the Industry and Electricity Department of China Railway Group introduced that since 2022, in order to adapt to the new situation of the rapid development of China’s railways, especially high-speed railways, China Railway Group has given full play to the role of the Railway Science and Technology Innovation Alliance and coordinated The talent team of relevant units such as industry, academia, research and application, adheres to the Oriented by on-site demand, in accordance with the overall principles of "product model pedigree, core technology autonomy, equipment function intensification, key components simplification, operation and maintenance management intelligence, and construction operations green", a new generation of fully autonomous R&D and manufacturing of large-scale road maintenance machinery with intellectual property rights. The new generation of large-scale road maintenance machinery includes 7 categories, including line and switch maintenance vehicles, rail and switch maintenance vehicles, and railway infrastructure testing equipment, covering 18 series such as tamping, cleaning, grinding, rail welding, and testing. The project has been developed 13 models, featuring high technology, high efficiency and high quality.

The person in charge said that the DWL-32K continuous traveling tamping stabilization vehicle and GCX-1000K track snow removal vehicle that will be put into use this time are developed by the China Railway Group, jointly with China Railway Construction Equipment and China Railway. It was jointly developed by the Academy of Sciences, Kunming Bureau Group Company, Taiyuan Bureau Group Company and other units. Among them, the DWL-32K continuous traveling tamping and stabilizing vehicle adopts more advanced intelligent tamping and stabilizing technology and is equipped with an intelligent analysis and control system, which can realize adaptive tamping and stabilizing operations, and can adapt to more complex operating conditions, making it The track bed maintenance quality is better and the operation is safer. It has advanced functions such as cruise control and intelligent maintenance, and can realize intelligent operation, intelligent operation and intelligent maintenance. The average operating efficiency has increased by more than 20%; the GCX-1000K track snow removal vehicle has made breakthroughs in many key technologies such as track snow removal under complex working conditions, derailment prevention during operation, and high-power diesel engine cold start. It is equipped with a special cleaning device for high-speed railway lines and adopts extreme cold resistance Environmental protection measures have greatly improved the adaptability to extreme environments and complex working conditions and the safety and reliability of use on high-speed rail lines.

The person in charge said that relevant railway departments will dynamically collect data from the first batch of trial large-scale railway track maintenance machinery and equipment, carry out scientific analysis, and continue to optimize and improve the performance and functions of the equipment.
