This research focuses on the development of a semi-automatic dual-axis pushcart loader designed to improve efficiency, safety, and ergonomics in industrial material handling. Traditional pushcarts require significant manual effort, often leading to worker fatigue and reduced productivity. To address these issues, the project introduces a semi-automated solution using battery power and hydraulic lifting systems. The prototype was designed, fabricated, and assembled using locally sourced materials. Key components included a 48V/10A lithium-ion battery, hydraulic scissor lifts, a 300W DC motor, and a custom-built platform. Autodesk Inventor and Fusion 360 were used for design modeling and stress simulations. Performance testing measured lift speed, battery efficiency, and load capacity. The prototype successfully lifted 50 kg, 100 kg, and 200 kg loads, with average lift and retraction times of 23.99 and 20.49 seconds, respectively. Stress simulations confirmed that the structure remained within safe limits under load. Battery performance remained consistent, averaging 30.34°C during operation. A panel of professionals assessed the prototype using a Likert scale, rating its functionality, safety, durability, aesthetics, and cost-effectiveness. It received an overall rating of 4.50 out of 5, classified as very good. In conclusion, integrating hydraulic and electronic systems significantly reduced manual labor and the risk of injury, while improving overall efficiency. The design shows practical promise for warehousing, logistics, and manufacturing applications. Future enhancements could include remote control, larger wheels, and adaptive load balancing for even greater usability.
