Construção de um equipamento para avaliação ergonômica de ferramentas manuais utilizadas no preparo de solos agrícolas.

Abstract

The present project had as objective the construction of equipment that carried through the ergonomic evaluation of manual tools. The equipment was constructed on a picture carries tools in the dependences of the Center of Agroveterinary Sciences, CAV/UDESC. A seeder Massey Ferguson was used for the construction of the base, on which a mechanism of three points for tractor coupled was constructed, that has for purpose to carry through the analysis and evaluation of the effort carried through in the use of hand tools. An experimental delineation in blocks with five repetitions for the measures of horizontal force in the handle of a hoe was performed. The results had shown that the force is a linear function of the time.
