Adaptação do método de classificação ergonômica de tratores florestais utilizados na colheita para colhedoras de cana-de-açúcar

Abstract

This study reports ergonomic evaluation of a sugarcane harvesting machine, operating in a sugarcane mill “Usina da Barra” located at Barra Bonita, São Paulo. The evaluation was done in January 2007, using the harvester that best performed during the 2006/2007 crop season. The evaluation was based on the recommendations of “Ergonomic Guidelines for Forest Machines”. The maximum ergonomic points were achieved by the work post, operator seat and operator’s manual. Access to work post was classified as ‘C’. The visibility of the stem base was the worst ranked item, at zero. All others items were classified as ‘B’. Taking all aspects into account the harvester was classified as ‘B’ form ergonomic point of view, which indicates potential for a highly satisfactory performance under less demanding working conditions.
