“…In essence, the interplay of the crank mechanism, the transmission screw, and the interconnected beams orchestrates a harmonious dance of mechanical energy conversion. This intricate orchestration achieves the transformation of rotary input into linear elevation, embodying the core essence of this scissor lift platform's operational principle (PAN et al, 2017).…”

This technical article introduces a pioneering educational approach that seamlessly melds Problem-Based Learning (PBL) with the practical development of a small-scale scissor lift. Encompassing the realms of design, simulation, and automation, the project offers students an immersive learning experience within the framework of a Machine Design course. By engaging in the conceptualization, design, prototyping, and automation of the scissor lift, students gain invaluable insights into the multifaceted dimensions of engineering practice. Problem-Based Learning serves as the foundational pedagogical strategy, encouraging students to collaboratively tackle real-world engineering problems. The scissor lift project becomes a microcosm of the engineering process, fostering critical thinking, teamwork, and communication skills. From the initial ideation and iterative design refinement to the application of Finite Element Analysis (FEA) to assess structural integrity, students learn to navigate challenges that mirror authentic engineering scenarios. The article delves into the pivotal role of simulation in refining the design's performance. By employing FEA tools, students gain competence in predicting mechanical behaviors, optimizing load distribution, and ensuring operational safety. The practical aspect of the project materializes during the prototyping phase, where theoretical designs transform into tangible prototypes. Load testing and iterative adjustments further imbue students with a hands-on understanding of engineering intricacies. Highlighting the contemporary relevance of automation, the project extends beyond conventional mechanical considerations. Arduino-based automation injects the element of control and precision into the scissor lift's operation.

Nowadays, more than the workforce is needed to transport heavy tonnage loads. So, movable scissors platforms are used when it is desired to transport loads from one location to another and lift them to a certain level. In this study, for the first time, the concept design and prototype production of the new generation scissor lift platform, which has a hydraulically assisted and automation-managed steering control system that will enable loads up to 6 tons of capacity to be transported and delivered to the appropriate height with precise control, has been carried out within Önder Group Inc. Design Center as a domestic product. Within the scope of the study, an automation-controlled hydraulic steering system was developed, unlike the manual steering control system used in equivalent models. This way, easy driving and control of high-tonnage mobile scissor lifts have been achieved. In addition, with the innovative linear bearing hydraulically driven movable upper table design, the materials placed on the table can be moved left and right precisely without moving the platform, thus providing ease of material assembly and time-saving. Within the scope of the study, static strength calculations were made using finite element analysis of the designed system. As a result of the analyses, it was determined that the stresses occurring in the system under service conditions affect the components homogeneously and that no plastic deformation will occur in the entire system. Thus, the design can be used safely.

“…Depending on the required capacity, scissor lifts can come in various sizes and configurations, from portable platforms that can be easily moved around to large industrial ones that can reach 15 m [1] or a lifting load of up to 1.0 tons [2]. Many studies have been conducted on scissor lifts to analyze the operation of the systems.…”

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.
