Abstract:

This research presents the design and performance test of a stair-climbing trolley. The aim of this project is to develop a mechanism for easy transportation of heavy loads over stairs. The need for such a system arises from day-to-day requirements in our society. In this research, the shaft diameter is calculated by using the bending strength of the beam. A mild steel shaft is selected for design to obtain high strength. Several designs were conceived that would allow a non-industrial hand trolley to travel over stairs, curbs, or uneven terrain while reducing the strain on the user. In our project, the trolley is equipped with Tri-Star wheels, enabling us to carry a load up and down the stairs. It also eases the movement of the trolley on irregular surfaces like holes, bumps, etc.
