This research presents the design and performance test of stair climbing trolley. The aim of this project is developing 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, shaft diameter is calculated by using bending strength of the beam. Mild steel shaft is selected for design to obtain high strength. The length of shaft is 21 in and the calculated diameter of shaft is 0.75 in. Bearing No: 204 of single row angular contact ball bearing is selected. The design is based on the bearing that can be only efficient for 60 kg load with the speed of the normal human.
