Design and Fabrication of Adjustable Wheelbarrow

Abstract

Previous studies provided evidence that young farmworkers and agricultural workers may be at risk of lower back musculoskeletal injuries. Effective interventions are needed to reduce the stressors that cause harm to minimize these risks. Since almost all work environments require manual operations, agricultural and peasant workers are very likely to bear heavy loads. Lower back pain and injury are considered one of the most common musculoskeletal diseases caused by weightlifting. However, several factors increase workers’ risk, such as weight, age, gender, and height. The purpose of the current research is to study alternative forms of the wheelbarrow as an intervention for young people to transfer materials on farms. Young people helped solve this problem by innovating a simple machine called an adjustable wheelbarrow, which can transport goods from one place to another place. The research first focused on the design of the tank scissor lift. It is good to make the new design have better ergonomic through some research on the scissor lift’s existing structure and materials. This project aims to fabricate the adjustable wheelbarrow used scissor lift and explore the influence of load position and force on muscle activity during the wheelbarrow task. Innovative wheelbarrow used to relieve back pain of users. Previous studies show that alternative wheelbarrow designs can reduce the awkward postures and motions during wheelbarrow tasks. Therefore, further research into the effectiveness of these interventions, including spine loading and long-term use, is necessary. The structural model was developed using computer-aided design software. Finite Element Analysis (FEA) software is performed to study the scissor lift’s deflection below the tank wheelbarrow after the load was applied.
