Abstracts: This project consists of the design, manufacturing and optimization of a stair climber. Stair Climber is having special importance for carrying loads/goods up/down stairs. They are generally used for reducing the effort required while carrying heavy loads by stairs. Stair Climbing Trolley makes use of mechanism which is guided by links and motion transmitting elements. The mechanisms are fixed below the conventional Hand Trolley to enhance the performance. This is an efficient way to reduce the effort for carrying the goods by stairs. Stair Climbing Trolley propels itself with the help of force applied through mechanism at the bottom of the trolley to lift it up and allow it to climb the next step with quite less human effort. This will eliminate necessity of another human effort to be applied to lift the trolley (Like in conventional Hand Trolley).
