A influência da organização do trabalho na atividade dos mecânicos de manutenção de redes hidráulicas em uma mineradora

Abstract

The security department of the work needed an Ergonomic Analysis of Work with the task of dismantling and assembly of pipes HDPE (high density polyethylene) of a network of hydraulic mining, because of complaints of physical fatigue mechanics during this task. It was hypothesized that the organization of work could be having an influence on the activity of these workers, and generating a result, complaints of fatigue. To perform this analysis used the methodology proposed by the Guerin et al (2001). The resources used were global observations of the mechanical activity, unstructured interviews, photos and footage. Were performed 80 hours of study in the area of mechanics work. Physical factors related to tools such as torches, stabilizing shoes, keys and frames combined were identified as determinants of physical overload these workers, and the consequent adoption of stereotypical attitudes by maintenance mechanics. Organizational factors such as division of tasks between the mechanical, time pressure and planning tasks have been identified as factors hindering the implementation of maintenance activity. Changes were recommended in the truck used by the team with a hydraulic system for opening and fitting shoes stabilizing the arm of a bucket truck, purchase of a mobile unit equipped with tools, acquisition of key ratchet, easel and portable battery generator, increased number of valves and hydraulic drains, promote training workers to perform all maintenance tasks, and improve planning of tasks with the team responsible. It was concluded from this work Ergonomic Work Analysis, enables researchers to understand the work from the analysis of activities and work situations more broadly. And that way you can afford and enough information to make working conditions so as to adapt it to the characteristics and variability of the man and the production process
