ELECTRIC POWERED STAIR CLIMBING TROLLEY

MECHANICAL ENGINEERING

The project aims to bring forward a way to move heavy objects over stairs. The necessity of such a system is clear from the day-to-day requirements of our society. Devices like hand trolley are wont to relieve the strain of lifting while on flat ground; however, these devices usually fail when it becomes necessary to barter a brief flight of stairs. Within the light of this, the project attempts to style a stair climbing hand cart which might carry heavy objects up the steps with less effort compared to carrying them manually. It also endeavors to check the commercial viability and importance of such a product. Several designs were conceived that might allow a non-industrial hand trolley to travel over stairs, or uneven terrain while putting minimal strain on the user. One strategy, a three-wheel rotating system, was selected for development and a number of other solid models were created and a prototype was constructed. The finished prototype was tested with a payload of approximately 100 kg, and it had been determined that the hand trolley design could be a viable option for a stair-climbing consumer product.
