Staircaseclimber trolley

The project aims to bring forward a means to transport heavy objects over stairs. The need of such a system is obvious from the day-to-day requirements of our society. Devices such as hand trucks are used to relieve the stress of lifting while on flat ground; however, these devices usually fail when it becomes necessary to negotiate a short flight of stairs. In the light of this, the project attempts to design a stair climbing hand cart which can carry heavy objects up the stairs with less effort compared to carrying them manually. It also endeavours to study the commercial viability and importance of such a product. Several designs were conceived that would allow a non-industrial hand truck to travel over stairs, curbs, or uneven terrain while putting minimal strain on the user. 

In our project, the trolley is equipped with Tri-Star wheels, which, as the name implies, is designed to go up and down stairs. It also eases the movement of trolley in irregular surfaces like holes, bumps, etc.
