Abstract
The aim of this case study was to analyze and evaluate the force risks associated with building metal towers structures using exoskeleton and without it in electrical technicians in high voltage lines. The data recollection was made using three different methods, a self-discomfort report, observational data (RULA and REBA) and muscular activity using electromyography (EMG). The results of the self-discomfort report showed a greater discomfort in wrist, hands, lower back and thighs. The outcomes of RULA analysis suggested that 51,6% of the activity postures were in high risk and the remaining in medium risk. REBA’s outcomes showed that 32% of the activity postures are classified as high risk and 65% in medium risk. About the EMG analysis, the mean difference analysis showed that there is no difference between using the exoskeleton and without. Finally, it is necessary to improve the working conditions instead of considering the usage of the exoskeleton.
