Abstract
The paper aims to present an analysis about pruning vegetation with hydraulic pole pruner, a task considered critical, performed by Live Line Electricians (LLE). The research was carried out at an advanced power station, located in the countryside of São Paulo/Brazil through the application in Ergonomics, Biomechanics and Cybernetics methods. It was possible to identify the critical determinants of the activity under study through the Activity Ergonomics, as well as to explain the physical issues through the movements simulation (biomechanics) in terms of medium and high pruning that confer bigger postural problems, especially of the trunk and upper limbs, validated by cybernetic analysis (3D), which allowed quantifying such elements in order to create demands for the tools design to alleviate this condition. It is suggested that the articulation between qualitative and quantitative analyses, explained here through the methods triangulation, although anchored in different epistemological keys, provide more complex and broad understandings about the working reality and the possibilities of transformation.
