Theme of the thesis is "Scissor lift". This thesis in detail describes the development of scissor lifts from concept to technical documentation. The introductory chapter describes the types of vertical lifts used for working at height. After introduction, detailed analysis of the market is presented together with existing solutions on the market. Based on the analysis, functional structure of the product, obtained by using morphological matrix, was made and possible solutions were determined. After detailed analysis and evaluation of possible solutions, best concept was selected. The selected concept was fully developed, necessary budget was created along with a 3D conceptual model and finally complete technical documentation of the selected concept was made.
