description: The topic of the final qualifying work: "The project of strengthening the metal structure of a coal loader". This work is based on the practical experience of operating a coal loader, during which it was established that the design does not meet the reliability requirements imposed on it by the condition of fatigue resistance. To analyze and find ways to improve the reliability of welded structures according to the condition of fatigue resistance, the following works were performed: 1. Determination of the geometric parameters of the influence of the design of a moving section with a rectangular pipe section on the stress concentration in welded joints. 2. Investigation of stress concentration by the finite element method. 3. General calculation of the telescopic section of the coal loader. 4. Development of options for improving the reliability of a coal-fired ship-carrier under the condition of fatigue resistance. 5. Justification of the decisions taken to ensure the durability of the metal structure of the coal loader for at least five years. As a result of the work, a project for changing the telescopic section was presented, which consists in changing the section of the lower belt of the ferry. A demonstration model of the ship loader design has been developed (Appendix A).
