Análise das condições ergonômicas e ambientais em postos de trabalho de motoristas: um estudo de caso sobre caminhões utilizados no meio rural e agroindustrial

Abstract

The transportation of cargo that moves the economy of Brazil is conducted with sovereignty through the road system, raising the driver of a truck to a profession of enormous importance for the various economic segments, especially for agribusiness. The objective of the present study was to evaluate the ergonomic and environmental conditions of truck drivers' positions that work in agribusiness related activities. The case study was carried out in the Western Frontier with professional drivers who perform tasks in rural and agroindustrial environments. For postural analysis, we performed filming and the generation of 240 sequential photos as a reference of the activity cycle. Through the software Ergolândia 6.0 the images were analyzed by the RULA method, which resulted in the need for intervention in the drivers posture. In addition, the workstations deserve ergonomic modifications as in seat adjustment and instrumentation panel. Through the Bipolar Questionnaire it was observed that the activity performed by the drivers presents a painful picture. Forced posture, high repetitiveness, discomfort, and fatigue put the biomechanical factor of the worker at risk. Regarding the occupational noise and temperature analyzes, no parameter presented comfort to the individuals according to the normalization of NR 17. The illumination values proved to be quite deficiente due to the lack of a specific standard for the interior of the truck cab. Through the anthropometry of the drivers participating in the study, it was noticed that there is a demand for modification in relation to the truck design for better comfort of the user population.
