“…Such seat and armrest variables must be dimensioned according to the anthropometric standards of the local workers. The machines evaluated in this study also showed some flaws regarding controls and instruments, since their location must be designed so that the arms reach them within their normal range of action in a way that the operator does not have to bend the back or move the body, thus avoiding greater fatigue and more time in the execution of tasks (BARRETO et al, 2013;SILVA et al, 2014). In relation to the commands moved by the legs, they may be more demanding of strength, as long as the ideal position is observed that allows the exact movement (MERINO et al, 2012).…”

The objective of this work was to evaluate farming machines adapted to forestry work and to verify if their characteristics meet the safety, ergonomics and working conditions necessary to maintain the health and safety of the operators. Thus, three farming tractors were selected, with a closed cabin and a minimum power of 73.5 kW, a widely used specification in the forestry sector. The following ergonomic parameters were considered: acess to the cab, cab dimensions, visibility, seat, controls and operation, work posture, cabin air conditioning, noise, lighting and maintenance aspects. The evaluations were based on the guidelines contained in the “Ergonomic Guidelines for Forest Machines” of the Swedish Forestry Research Institute, developed for forestry machines. The results showed that all the evaluated machines presented ergonomic standards below those indicated in all evaluated aspects, particularly related to access to the work station and difficulties during mechanical maintenance, besides the necessity of adopting forced postures during the working day due to operator’s seats. It was concluded that the farming machines adapted for work in forest processes presented significant gaps in relation to the ergonomic aspects, which represents high and imminent risks of development of occupational diseases in their operators, as well as the predisposition to work accidents.

-This study aimed to assess different types of machines adapted for mechanized forest harvesting activities in order to quantify the degree of compliance with ergonomic principles applicable to forest machines, as well as the ergonomic risks to which workers are exposed. The following machines were evaluated: a feller buncher adapted into a wheel loader; a mini skidder coupled to an agricultural tractor; and a forest loader adapted to an agricultural tractor; operating in the states of Paraná and Minas Gerais. Biomechanical working conditions were assessed by applying a checklist for simplified assessment of the workplace biomechanical conditions. The forced postures assessment was performed using the REBA -"Rapid Entire Body Assessment" method. In turn, ergonomic classification was through guidelines contained in the ergonomic classification manual "Ergonomic Guidelines for Forest Machines". Moreover, the environmental factors noise, temperature and vibration to which the operators of these machines were exposed were assessed. The results showed all assessed machines had ergonomic standards below those indicated in all assessed aspects, mainly related to access and dimensions of the workplace, need to adopt forced postures during working hours, and exposure to environmental factors assessed above tolerance limits. It is concluded that machines adapted for use in forest harvesting processes have shown significant gaps in relation to ergonomic aspects, presenting high and imminent risk of development of occupational diseases in their operators.Keywords: Forest operations; Forest mechanization; Occupational health. PRECARIZAÇÃO DO TRABALHO: RISCOS ERGONÔMICOS AOS OPERADORES DE MÁQUINAS ADAPTADAS PARA COLHEITA FLORESTALRESUMO -Este estudo teve como objetivo avaliar diferentes tipos de máquinas adaptadas para as atividades de colheita florestal mecanizada, de forma a quantificar o grau de atendimento aos princípios ergonômicos aplicáveis às máquinas florestais, bem como os riscos ergonômicos aos quais os trabalhadores estão expostos. Foram avaliadas as seguintes máquinas: um feller buncher adaptado em uma pá carregadeira de rodas; um mini skidder acoplado a um trator agrícola; e um carregador florestal adaptado a um trator agrícola; operando nos estados do Paraná e Minas Gerais. As condições biomecânicas do trabalho foram avaliadas através da aplicação de um check-list para avaliação simplificada das condições biomecânicas do posto de trabalho. A avaliação das posturas forçadas foi realizada utilizando o método REBA -"Rapid Entire Body Assessment". Por sua vez, a classificação ergonômica foi através das diretrizes contidas no manual de classificação ergonômica "Ergonomic Guidelines for Forest Machines". Ainda, foram avaliados os fatores ambientais ruído, temperatura e vibração aos quais os operadores destas máquinas estavam expostos. Os resultados apontaram que todas as máquinas avaliadas apresentaram padrões ergonômicos abaixo dos indicados em todos os aspectos avaliados, principalmente relacionados ao ace...
