Micro ergonomia - desenvolvimento de um cabo ergonômico para enxadas.

Abstract

Ergonomics is the primary way to promote improvements in the work environment for the wellbeing of the worker, as well as efficient and quality productivity. Agriculture is one of the fastest growing markets in the country, even with its expansion and modernization, many activities are still very manual and use tools that pose risks to human health. From this discussion to the study of the use of the hoe to perform the weeding activity was developed. First, it was necessary to understand the activity to identify its negative points, and thus to enable the development of ergonomic solutions. The weeding activity using the conventional hoe was evaluated by the RULA method, which analyzes the use of the biomechanical overload of limbs in an occupational task. After analysis, it was possible to prove the need for short-term interventions in the tool used. The hoe rope was identified as one of the main aggravating factors in the case studied, since it does not provide the minimum of adaptation to its users, forcing them to adopt incorrect postures. Then the proposal for a new hoe rope was developed, ergonomically constructed to ensure a safer execution of the activity, designed from simple and economically viable adaptations, thus ensuring that the new product is within reach of the workers.
