Dimensionamento estrutural de ponte rolante para desmanche de caminhões

Abstract

Overhead cranes are suspended metallic structures, horizontally arranged, that move along rails to lift and transport heavy loads. Designed to be highly resistant and to have a wide range of motion, they play a fundamental role in the displacement of heavy materials. This study aims to design an overhead crane to be used in the dismantling and storage of parts at a legalized truck salvage yard located in Teresina, Piauí, based on the classification criteria of NBR 8400:2019, supported by the limit states established by NBR 8800:2024. The structure will be of the single-girder type, housed inside a warehouse measuring 10 m in width by 30 m in length, with a maximum load capacity of up to 5 tons. The analytical calculations performed in the design of the crane’s components were validated using ANSYS software, which showed high convergence between the numerical and analytical results, thus representing a robust and safe structure capable of fulfilling its intended purpose.
