“…Karagülle et al [6] employed finite element analysis (FEA) on a 3D model created in Solidworks to ascertain the internal loads acting on each component of a single-layer system. Dang et al [7] proposed using the parametric method to model single-layer scissor lifts and construct mathematical equations to determine cylinder loads and reactions at the joints. Using the same approach, Todorović et al [8] applied Harris Hawks optimization (HHO) to reduce mass in the mechanism frames.…”

This study presents a calculation procedure of applying the statistical method in determining design parameters for double-layer scissor lifts to improve their operation (e.g., lifting height, loading, stability). By parameterizing the mounting orientation of cylinders, the working of the mechanism is summarized as functions and evaluated. To verify the accuracy of obtained equations, a 2D model of the mechanism was constructed and simulated using Working Model software. The results obtained from the simulation indicate that by adjusting the mounting positions of cylinders, the platform’s position and reactions on the device can be determined, enabling improvement of the system’s performance. The results obtained from the study show the practical significance of applying parametric methods to the calculating process and optimizing the structure of multiple-layer scissor lifts.

“…The simulation process is applied to calculate the size design and determine the control parameters of the scissor lift cylinder in order to improve the system's efficiency. In solving static problems for singlestage scissor lifts, Dang et al [12] suggested using dimensional parameters to analyze the influence of the cylinder's orientation in the operation of the model. Results from the study reveal that if the lift's height is fixed, the thrush force of the cylinder is constant, regardless of the position of cargo on the platform.…”

Scissor lifts are widely used in industry. The selection of a configuration of lift table system plays an important role since this depends on the working requirements of the systems and also the type of lift object. In this paper, based on the parametric dimension technique, the mathematical model of the configuration and the load calculation for the double-stage scissor lifts, which depends on the design parameters, were investigated in order to enhance the operation of scissor lift systems (e.g., lifting height, loading, and stability). A 2D-model of the system was constructed and simulated in the Working Model software to verify the accuracy of the proposed method. The results obtained from the simulation indicate that by adjusting the mounting positions of cylinders, the elevation of the platform and reactions on joints of the components can be calculated, which assists in improving the performance of the system. Furthermore, the results also prove the practical significance in the calculating process and dimensional design of scissor lifts, especially for double-stage structures.

In this study, the design of a two scissors greenhouse lift trolley is considered. The maximum height of the platform from the ground is 3500 mm. A program developed in Visual BASIC to automate the design is introduced. The lift is modeled in SolidWorks (SW) and the finite element (FE) modal and static analyses are performed as an initial design first by using graphical user interface (GUI). The lift contains revolute joints and slider joints. A simply supported beam which has two revolute joints and a slider joint is studied to verify how to model the joints. Pim connectors are defined for revolute joints in SW-FE analysis. Spring connectors with very large values are defined between sliding faces in the normal direction for translational joints. The results obtained with solid finite elements in SW are compared with analytical results for the natural frequency and static analyses and it was observed that the results are in good agreement for the simply supported beam. An Excel file where a main sheet contains the list of the bodies and all the geometric values is created after the initial design. The Excel file also contains sheets for each body. Body sheets have all the dimensions in the sketches and features. The dimension values in the cells of the body sheets are defined by formulas related to the geometric values given in the main sheet. Kinematic, kinetic, and revision of the SW model are performed by the design automation program. The FE analyses are done by GUI and the results are evaluated. If the results are not satisfactory, the geometric values are changed in Excel file and the analyses are repeated. The final design is obtained by the iteration easily. The automation program and the procedure developed in this work can be extended other scissors lifts.
