Nevertheless, the preservation of train power transmission lines presents noteworthy hazards as a result of the amalgamation of electrical perils and maintenance-associated risks. This study aims to present the design and simulation of a planar translational scissor lift mechanism. The objective is to assist maintenance personnel in the rail sector specifically during power transmission line maintenance. The scissor-lifting mechanism was modelled in Solid Works, a software programme known for its comprehensive 3-D modelling capabilities. Additionally, a mathematical model was constructed to analyse the behaviour of the scissor lift. The dynamic response of the system was investigated through the utilisation of MATLAB/Simulink to conduct kinematic and kinetic simulations. The research findings unveiled the comparative kinetic correlation between the hydraulic cylinder and other constituent elements, effectively capturing their dynamic behaviours throughout the operational process. In addition, the utilisation of Simscape facilitated the optimisation of the mechanism's design through simulation analysis, thereby offering valuable insights to inform and improve subsequent design iterations. The experimental findings indicate that the system design effectively raised the maintenance platform to a height of 2 metres in a time of 20 seconds while accommodating a load range of 500 to 1000 kg. The study presents a systematic and logical design approach that establishes a scientific foundation for the mechanism. This positions it as a valuable theoretical reference for future advancements in scissor lift development. The results of this study make a valuable contribution towards enhancing safety and efficiency in rail maintenance operations. Additionally, they help in reducing the risks associated with power transmission line servicing. Furthermore, these findings lay the foundation for future advancements in railway maintenance technology.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/MaintenanceRailway infrastructurePlanar translational scissorModellingLift mechanismPresentation
