Design and Prototype Production of Scissor Lift Platform 25 Tons Capacity

In this study, an innovative 25-ton-capacity scissor lift was designed for the first time, and a prototype was produced in Onder Group Inc. Within the scope of the study, a rolling bearing system was designed instead of the conventional welded scissor-hinge connection system. Static and strength calculations were made using finite element analysis for comparison purposes. As a result of the analysis, it was determined that the stress distribution on the roller bearing system was more homogeneous and at lower values (≈60 MPa) than the welded hinge system. In addition, a detachable (bolted) joint was obtained instead of a fixed (welded) joint with the designed rolling bearing system. With the design analyses carried out within the scope of the study, a particular joint-clamp system was made to expand the surface areas of the welded joints.
