Aspectos ergonômicos da colheita florestal mecanizada: uma revisão bibliográfica

Abstract

This paper presents a review of the literature on the ergonomic aspects of the mechanized forest harvest, which is carried out with reference to articles in journals, textbooks, dissertations, theses, projects and navigations through the internet. The research focused on publications directed to the subject, using as keywords: forest mechanization; forest harvesting; forest ergonomics; worker's health; occupational diseases; accidents at work. The period defined for the research was from 1979 to 2018. It was possible to verify that, since the high degree of mechanization of the forest harvesting activities, the machines still present ergonomic gaps and that it is necessary to adapt these machines to the physical conditions of the Brazilian operators; that there are imminent risks of developing pathologies related to the vertebral column, low back pain, herniated disc, musculoskeletal disorders and psychosocial diseases in its operators; and that such pathologies are related to conditioning factors such as high demand of operators' time in the same task and positioning, repetitive activities of high cognitive and motor requirements, exposure to noise, gases, vibrations, poor seat adequacy, cabins and access to machinery.
