Abstract

The object of this study was to conduct an ergonomic analysis of the prototype hydraulic pit dig, taking into account the aspects of posture, workload, biomechanics, vibration and noise. The anthropometric variables obtained were used for the design of the prototype. The results showed that among the movements performed by the operator during the activity, we highlight the trunk inclination during the drilling of soil and transport the equipment to draw a line to the other, associated with rotation of the trunk, plus the support and material handling. The activity of the prototype hydraulic tillage does not expose workers to situations of physical strain. However, during the phase shift between pits, 99% of workers showed risk of injury to the elbow joint and vertebral disc L5 - S1 and 89% of workers to the knees. The noise and vibration emitted by the equipment are in accordance with the values recommended by Brazilian legislation. The prototype hydraulic presents the advantage of the possibility of reverse rotation constant, making it suitable for application on some machines.
