Human Powered Stirrup Making Machine Design & Fabrication

Stirrup is one of the essential elements of reinforced cement concrete in civil construction. These stirrups are used for strengthening column and beams for avoiding buckling of long slender column and also avoiding sagging of horizontal beam. In small construction sites workers bend stirrup rod by using traditional method. In traditional method stirrups are made on a wooden platform provided with pins and rod is bend using a lever like hand tool 'daag' .There is no other way to make stirrup with less human effort and the same time the detailed study of present manual stirrup making activity indicates that the process suffers from various draw back like lack of accuracy and low production rate which results in weak structure and instability in column and beams. In the existing stirrup making operations, the operators have to expend high human energy because of continuous repetitive motion of hands for a long duration which results in very severe internal injury to body organs like carpel tunnel syndrome, spondylitis, muskulo-skeletal disorder, etc. In order to compensate above drawbacks the aim is to design and fabricate Human Powered Stirrup Making Machine.
