Abstract
The article discusses the development and research of a mobile overpass as an engineering solution in the field of mechanical engineering and transport technology. It describes the design features of the overpass: the load-bearing span integrated into a two-axle wheeled chassis, the tensioning mechanism, and the suspension system, which ensure reliability and stability under dynamic loads. The technological advantages of the design are shown: mobility, quick installation without major construction, modularity, and the possibility of repeated use in various operating conditions. Based on preliminary engineering calculations and analysis of transport loads, the strength and operational reliability of the structure when moving passenger cars and light-duty vehicles is justified. The use of reinforced guide elements and a spatial truss scheme minimizes deformation and evenly distributes loads. The economic analysis confirms the efficiency of the proposed overpass's installation and operation, demonstrating a total annual saving exceeding 18 million tenge, primarily through reduced fuel consumption and minimized vehicle idling time. The results of the study confirm the feasibility of introducing mobile overpasses as an effective engineering solution that ensures the maintenance of transport links during major repairs and reconstruction of roads. The design combines manufacturability, mobility, and operational reliability, which opens up prospects for its widespread use in Kazakhstan's transport infrastructure
