Abstract: The increasing demand for efficient and space-saving tools in workshops and households has led to the development of innovative solutions that combine multiple functionalities into a single product.This project focuses on the design and fabrication of a 2-in-1 trolley, which serves as both a load-carrying trolley and a ladder.The primary objective is to address common challenges faced by workers and individuals, such as transporting heavy items and accessing elevated storage areas, without the need for separate tools.Conventional methods require separate ladders and trolleys, resulting in higher costs, increased storage space, and reduced efficiency.The proposed design offers a compact, lightweight, and cost-effective alternative that enhances convenience and productivity.The 2-in-1 trolley is constructed using mild hollow steel for strength and durability, complemented by heavy-duty rubber wheels with locking mechanisms for mobility and stability.Anti-slip mats are integrated into ladder steps to ensure user safety during climbing.The design emphasizes ergonomics, portability, and ease of transformation between trolley and ladder modes.The fabrication process involves cutting, drilling, welding, and assembly of components, followed by surface finishing to prevent corrosion.Safety measures, including proper PPE usage and adherence to machining guidelines, were implemented throughout the fabrication process.Performance evaluation included pre-testing and post-testing phases, covering load capacity, stability, and usability.The trolley demonstrated the ability to carry loads up to 85 kg and function as a stable three-step ladder, meeting the design specifications.User surveys indicated high satisfaction, with over 90% of respondents agreeing that the product is compact, easy to use, and suitable for small spaces.Cost analysis revealed a total fabrication cost of RM 211.60, significantly lower than purchasing separate ladders and trolleys, confirming the economic viability of the design.The project has practical benefits, including reducing physical strain, saving time, and optimizing storage space, making it ideal for workshops, garages, and domestic use.Additionally, incorporating smart features such as sensors for stability monitoring could further enhance safety and functionality.In conclusion, the 2-in-1 trolley project successfully achieves its objectives by delivering a versatile, durable, and cost-effective
