Structural Analysis for Stairlift Chair Design

Medical technology plays a major role in supporting the elderly and disabled people. This study aims to make it easier for those people to climb stairs. A design for a stair lift chair was presented, considering both lifting and tilting mechanisms. Technical details of both mechanisms have been discussed, considering mechanical and electrical parts in terms of hardware and software. The chair is distinguished by its ability to adapt to various building structures without the use of a hydraulic system. In addition, the chair is a low-cost option compared to existing solutions The chair was tested with users of weights ranging from 70 kg to 100 kg. All calculations were performed considering the weight of 100 kg. As a result, the stair chair is a convenient assistive tool that facilitates the daily lives of disabled people.
