SMART ADJUSTABLE UTILITY TROLLEY

Abstract

The trolley is a fundamental mechanical device for transporting loads. Traditional designs, however, are often task-specific, which limits their versatility and can lead to ergonomic issues like user strain from bending to lift heavy items. This project introduces a smart adjustable utility trolley that integrates a scissor jack mechanism to provide adjustable height, directly addressing these limitations. By combining features from airport and shopping mall trolleys, the design emphasizes ergonomics, functionality, and affordability. The primary goal was to develop a durable, multifunctional, and user-friendly trolley that minimizes physical strain. The methodology included a literature review, conceptual design, material selection, fabrication, and a comparative analysis. The resulting prototype is a cost-effective and easy to maintain. Key future enhancements include incorporating a weight measurement system to prevent overloading. This innovative lifting trolley presents a practical solution for handling heavy loads, significantly improving convenience and user safety.
