A parametric approach to the design of single-stage scissor lifts

Scissor lifts are widely used equipment across various industries. Due to their simple structure and ease of operation, selecting the appropriate configuration for manufacturing to meet specific operational requirements remains a design challenge. This paper introduces a parametric approach using the vector-loop method to establish the relationship between the elevation of platforms and the placement of cylinders in single-stage scissor lift systems. Based on this relationship, precise control of platform movement can be achieved, enhancing system stability. Furthermore, the study investigates the effects of external loads and cylinder placement on the resulting thrust force, offering valuable insights for selecting optimal installation parameters. The accuracy of the proposed method is validated through comparisons with 2D geometric models constructed in GeoGebra and simulations performed in Working Model software, demonstrating the method's effectiveness in optimizing scissor lift design and configuration. The results of this study can be compiled into a technical reference, assisting designers in selecting suitable cylinder arrangements and components to meet specific system requirements.
