Tri-wheel trolley / Muhammad Ikmal Halimi Ismazi

Nowadays simple mechanical devices, such as hand trolleys with single and dual wheels, are finding widespread usage in a variety of businesses and households. However, its use is confined to transporting products from one position to another across the floors. There are no established designs on the market that meet the demand for assistance in moving the load oversteps. To overcome this challenge, stair wheels with three wheels are utilised as an alternative, reducing the effort of lifting. The current work focuses on the design and fabrication of a tri-wheel stair climbing hand trolley to move through uneven surfaces and transfer significant weights upstairs with the enhanced wheel arrangement while requiring significantly less human labour and manufacturing expense. The design considerations are explored, including the steepness of the steps, the stability and speed of the trolley while mounting the stairs. Hybrid trolleys, such as tri-wheeled trolleys, can be used to transport several things in places where mechanical elevators cannot be constructed [1].
