Abstract

This study was conducted to assess ergonomic efficiency of improved hanging type cleaner grader. Twenty farmwomen were selected to assess and compare the impact of improved technologies over traditional one. The physiological cost of work and energy expenditure in terms of heart rate, cardiac cost, time required, strokes, output were observed to be lower while performing selected activities with the improved technologies compared to the traditional one. The work output was also found higher with all of the improved technologies. The activity was performed with both the traditional method using as well as by using Supa, the improved tools. Results of the study showed that the average heart rate and energy expenditure of the women were reduced significantly while performing the grain cleaning activity with the use of improved tool manufactured by CIAE, Bhopal. The use of both the improved tools also led to reduction in the muscular stresses. Further it was observed that work productivity with the improved tool Hanging sieve had significantly improved. It was therefore recommended that women should be motivated to use the improved tools for grain cleaning to minimize health hazards.
