Design and fabrication of stair climbing trolley

This project describes the design and construction of a stair-climbing trolley to improve the movement of products over uneven terrain, notably staircases. The growing need for effective logistics solutions in the residential, commercial, and industrial sectors demands the creation of novel instruments that decrease physical strain and increase mobility. The trolley is designed with a unique wheel layout that allows it to easily ascend and descend stairs. It has a lightweight yet durable frame made of high-strength materials, assuring longevity and convenience of use. The design has a simple user interface that allows for straightforward use even by persons with limited physical strength.
