Projeto estrutural de guindauto para uso agrícola conforme norma ABNT NBR 14768

Abstract

It was noticed that when it comes to moving agricultural products, using one-ton Big-Bags, on small and medium-sized agricultural properties, there is a gap in the current crane market. These properties require medium-sized equipment, and this does not carry out activities that justify the use of two joints, as is normally offered by businesses in the region, therefore developing the mechanical design of equipment in these conditions is what this project proposes. work. The methodology used boils down to the development of a geometry, seeking the appropriate dimensions for the equipment to carry out the proposed activities, considering its use in conjunction with a Ford Cargo truck. From the definition of the geometry, all loads that must be considered in the project were determined, as well as safety factors and load increase factors, using the ABNT NBR 14768 standard. After that, using the finite element method, - a mechanical assessment of the main components is carried out, determining the thickness of the appropriate sheets so that the equipment is functional; Furthermore, the rack and pinion system responsible for the equipment rotation system was analytically dimensioned. As a result, a equipment was obtained, capable of performing the function of moving Big-Bags.
