Design and analysis of a scissor lift for remote maintenance in fusion reactor

Abstract

This thesis focuses on mechanical design and analysis a two-story scissor lift. It's made for doing remote maintenance work in fusion reactors. Based on literature review and market research, benchmarks the Autoquip Super Titan STN-012-0410 and JLG ERT2669, target dimensions were established, and a detailed 3D CAD model was created. Finite Element Analysis is conducted by applying a 20-tonne load at the top platform, demonstrated acceptable deformation and stress levels, yielding a safety factor of approximately 0.95 at its fully extended position. While aspects like material cost and radiation shielding were not addressed, the study lays a solid foundation for further refinement of heavy-duty lifting systems for fusion reactor applications.
