Conformidade ergonômica dos controles no posto de trabalho do operador de trator: estudo de caso NH 7630

This article discusses an ergonomic analysis of the controls used by tractor operators, covering their positions in relation to the casing of your job. Was performed an assessment of the controls of the job of a model NH 7630 tractor average power of 74 kW (100 CV), using the norms of the ABNT. With this screening could detect the positive and negative. Then was accomplished an analytical study of the controls. Evaluation results show that some controls of tractors have errors evaluated in relation to NBR/ ISO 6682.

Comparativo ergonômico de duas metododologias para aquisição de coordenadas tridimensionais do posto de trabalho do operador de trato

This research aimed to the comparison between two methods for obtaining three-dimensional coordinates of the controls of the upper limbs of the job of the tractor operator. The methods used were based on NBR / NM / ISO 5353 - Road machines, tractors and agricultural and forestry machinery – Reference point of the seat. The first method used follows the principles recommended by the standard NBR/NM/ISO/5353 The second method is an adaptation of this standard with the introduction of a laser measuring equipment developed by Silva (2009). The results were compared statistically to evaluate differences between the methodological processes involved. In this research, data was collected thought a brand new tractor Massey Ferguson model MF 292, awarded by the dealership from Londrina. The results have shown a considerable variation between the traditional measurement process and the laser measuring. It must be considered that this variation can be used to calibrate the tractor controls positioning, therefore the tractor is not in accordance to ABNT.
