This thesis focuses on the optimization of cable ladders with the aim of reducing weight and improving load capacity. Given the growing demand for electrical power, it is essential to have efficient cable management systems. Cable trays, which facilitate the organization and protection of cables, must be adapted to various conditions and materials. Technological advancements allow for the development of lighter and more durable solutions. The paper begins with a comprehensive analysis of existing solutions on the market, including different types of cable ladders and their materials. Through experimental testing and simulations, including the Finite Element Method (FEM), the effects of variations in parameters such as height, width, and wall thickness on the load capacity of the ladders were investigated. The optimization involved reducing the weight of the rung and decreasing the von Mises stress on the rail, resulting in increased load capacity and reduced weight. The improvements presented in this thesis enhance the efficiency, safety, and long-term sustainability of cable ladders. The paper provides a foundation for future research and development of new technologies in the construction of cable ladders, emphasizing the economic and ecological benefits of optimization.
