| Summary: | A wheelbarrow is a small usually single-wheeled vehicle that is used for carrying loads and is fitted with handles at the rear by which it can be pushed and guided. The wheelbarrow is designed to distribute the weight of the load it is carrying between the wheel and the operator. Wheelbarrows consist of simple machines lever, wheel and axle, and inclined plane. This study helps farmers performing farm and construction workers who may be at risk of developing a low back musculoskeletal injury. As for prevention, effective interventions to reduce pain are needed. The objective is to fabricate alternative wheelbarrow styles that can reduce the force and work done to carry a certain amount of load can reduce the risk of getting a low back musculoskeletal injury while performing different wheelbarrow tasks (pushing, pushing over bumps, and dumping). This study has discovered that modern wheelbarrows lessen the time taken to transfer load from one place to another by 53.8% compared to manual wheelbarrows. This result has been collected through some calculations. The gear reducer system, which is connected to the pulley system, also helps to lessen the load by 20%. The modern wheelbarrow focuses on reducing the force needed to transfer the material using the wheelbarrow and the correct body posture that may match the ergonomic standard such as the user’s comfort. The results showed that adding brakes on handles as brake and stopping mechanisms can fixate the wheelbarrow’s position, the four-wheel concept for stabilizing, and the pulley and chain system reduce the force needed for elevation. The cost to make this alternative wheelbarrow might be more expensive than regular wheelbarrows. Therefore, the researchers are trying to make this report to convince people that the modern wheelbarrow is worth buying |
