Avaliação ergonômica de um trator florestal Forwarder, utilizado na colheita florestal mecanizada

Abstract

This study wanted to show that technification of the forestry harvesting processes have contributed to a reduction in the labor and the number of labor accidents, not been capable of eliminating the risks of injuries to the workers involved in this activity. The forest machine analyzed was Forwarder (John Deere brand, model 1710D), been used in the states of Minas Gerais and Parana, Brazil. The parameters were the following: access to the pit, commands and instrument, seating, pit (place of work), climatization of the pit, visibility, noise, illumination, vibration, gas and dust fumes. These parameters were checked accordingly to checklist proposed by ALMQVIST et al. (2006). After that, there were classified accordingly to the ergonomical profiles in five classes, from A (the best ergonomical condition) until E (the worst ergonomical condition), de European framework of ergonomics and safety in harvesting forestry equipment (GELLERSTEDT, 2006), having Forwarder taking a B classification. This shows those therefore is a machine with a high technological standard and have satisfactory levels of safety, there is an ergonomical project with gaps, meaning that the risks of injuries exist in a smaller or bigger degree.
