Design and Fabrication of Stair Lift

In our country, a large number of people accounts for old aged groups, physically differently able people with damaged limbs due to accidents which faces severe problem in climbing staircases at public buildings, parks, old residential buildings, their private homes. Also the maximum number of buildings is not equipped with elevators or escalators. Most of these buildings have certain limitations of installing elevators or escalators. Hence, Stair lift proves to be effective way to tackle such problems faced by India and can be game changer for handicapped & old aged population of India. A stair lift is a mechanical device which is used to lift people and goods up and down on the stairs, who may find it difficult in doing so themselves. In this a rail is mounted along the treads of the stairs. A chair or carriage is attached to the rail. A person on the chair or carriage is lifted as the chair or carriage moves along the rail. Our main aim is to design stair lift for Curved Tracks using optimized driving mechanism, also focusing on modular design aspect while designing the system in order to make assembly trouble free and less time consuming during assembly as well as during maintenance and to carry out results for fail safe design. The general considerations of outcomes in design and manufacture of a Curved stairlift which should be useful for lifting people weight up to 120kg.
