Design and Finite Element Analysis of a Hydraulic Mobile Elevating Work Platform

Mobile Elevating Work Platforms (MEWPs) can provide speed and flexibility, especially in areas such as painting, maintenance, cleaning, and warehouse operations, which require overhead access. This study presents the design and finite element analysis (FEA) of a novel hydraulic MEWP that enables both vertical and horizontal movement, enhancing operational flexibility and personnel safety compared to conventional systems. The main frame of the platform is designed to be movable and foldable, with stabilization legs that secure it in place during operation. The platform design includes a vertically movable section on the main frame and a horizontally movable suspension section attached to this part. Analyses were performed under maximum loading conditions. For the structural analysis, boundary conditions and material properties were defined based on the maximum total load to be supported by the system, excluding the cabin section of the platform. Based on the analysis results, the maximum stress on the platform was measured at 54.8 MPa, while the highest displacement observed in the structure was 15.8 mm at the sling section. Considering the working and loading conditions, the safety factor of the designed mobile lifting system was found to be 4.4, and it was concluded that the system offers a viable solution in terms of functionality.
