Design and Fabrication of Staircase Climbing Trolley

Transporting heavy loads on staircases is a difficult and physically demanding task in many environments such as warehouses, residential buildings, hospitals, and construction sites. Conventional trolleys are suitable only for flat surfaces and cannot move efficiently on staircases. This paper presents the design and fabrication of a staircase climbing trolley which can easily move loads up and down stairs with minimum human effort. The trolley uses a tri-wheel mechanism that allows continuous rotation and smooth climbing over stair edges. The design focuses on strength, stability, portability, and ease of operation. The materials and components used in the fabrication include mild steel frame, rotating wheel assembly, axle, and handle structure. The fabricated model was tested on different staircase conditions to evaluate performance. The results show that the trolley can transport loads safely and efficiently over staircases with reduced human effort. This system can be useful in industries, hospitals, residential buildings, and delivery services.
