This paper presents a methodological development of the solution for the task of making a passenger transport mechanism for the airport Split - Kaštela. The mechanism, in addition to driving from point A to point B, must have the possibility to vertically adjust passenger cabin. This concept is developed in order to reduce the aircraft supply time and the costs of the airlines and the airport itself. After getting acquainted with the basics of the mechanisms theory, and studying the already existing products and solutions of the lifting mechanism, we move on to the conceptualization of variants that would be the most ideal solutions to the mentioned problem. For this purpose, we use methodical product development, which includes creating a list of requirements and wishes, functional structure diagram, morphological box, development and dimensioning of variants and technical and economic evaluation. After selecting the most ideal variant, workshop drawings, 3D model of the concept were made and the construction was tested for stress using the ‘Stress Analysis’ AutoCAD Inventor tool.
