Dimensionamento de uma ponte rolante para carga máxima de cinquenta toneladas utilizando software Livre Scilab

Abstract

Lifting and transport equipment is chosen and sized according to needs and physical constraints. Due to its versatility and robustness, allowing the movement of loads longitudinally, transversely and vertically, the overhead crane is one of the most used equipment within industries. In this sense, the work proposal is the design of a double girder overhead crane with capacity to handle loads of up to 50 tons, with a free span of 10 meters and a lifting height of 5 meters. The structural calculation procedure is based on the ABNT NBR 8400:2019 and ABNT NBR 10084:2020 standards, which establish the minimum criteria for sizing equipment for transport and lifting loads and define the minimum requirements for the design of steel structures , respectively. After adopting assumptions, the design and analysis of structural criteria for the equipment that make up the structure were carried out using the free Scilab software. Finally, the main objective of this work was achieved by dimensioning an overhead crane, focusing on the dimensioning of the equipment components and evaluation of the loads and requests acting on the structure that were satisfied.
