Engineering design of lifting device weighing up to 3.5 tons

Abstract The paper deals with the engineering design of lifting device weighing up to 3.5 tons. The first part is devoted to market research and the use of lifting equipment. Variant with a scissor construction and a hydraulic drive is chosen. The design itself follows. The machine composes five main parts: the lower frame, the scissor structure, the ramp, the mechanical lock and the drive mechanism. The individual chapters are devoted to design and analysis of these components.
