Development of a multi-purpose bulldozer loader design

Abstract

When maintaining, repairing, and constructing high-altitude highways, high-tech, multifunctional mechanized equipment is required to ensure uninterrupted transport communication. This is due to the fact that snowfalls, mudslides, snowdrifts, and avalanches can occur at any time of the year in high-altitude regions, along with frequent landslides and other natural hazards. Analysis has shown that performing complex construction, repair, restoration, and maintenance work on high-altitude highways, local roads, and city streets—where the workload is relatively small but requires numerous specialized machines (a complex of machines)—is often inefficient and, in some cases, impractical. Additionally, in a market economy characterized by the emergence of powerful private sectors, joint-stock companies, and other self-governing enterprises, the demand for multi-purpose machinery, capable of performing multiple functions within a single unit, has grown significantly. Based on an analysis of existing construction and road machinery designs, and considering the functionality of the proposed design, the structural features of a multi-purpose bulldozer-loader with a transformable working body have been systematized in a scientifically substantiated manner. Furthermore, the classification and determination of machinery and equipment types have been carried out based on an assessment of existing road construction machinery and equipment designs, as well as the functionality of the proposed model. This paper proposes the design of a multi-purpose bulldozer-loader with transformable working equipment, enabling high-efficiency, safe, and high-quality construction, maintenance, and repair of mountain roads with minimal costs.
