A atividade de troca de cruzeta por eletricistas de linha morta : o olhar da ergonomia sobre a atividade

Abstract

The activity of changing electrical crossarms is quite common in the work routine of de-energized line electricians (dead line – DL). Despite this, these workers complain that the activity is difficult, complex and tiring. Replacement of electrical crossarms occurs on a programmed, preventive or emergency basis and is currently carried out only by contractor electricians, but until recently it was also part of the work routine of electricians from the energy concessionaire. The material of the crosspieces, format and type of structure interfere with the complexity of the activity, but there are several other predictable and unpredictable variables that will require electricians to make a series of adjustments for their execution. Thus, the follow-up and analysis of the crosshead exchange activity were carried out, as well as its variability for a better understanding of the problem. The verbalizations and self-confrontations obtained through the Ergonomic Analysis of Work (EAW) allowed the elaboration of recommendations (organizational and in relation to work equipment) to promote improvements in working conditions and less physical, cognitive and mental exhaustion in the activity of changing electrical crossarms.
