Čuchor, Matúš, title: Engineering design of lifting device weighing up to 3,5 tons. [Engineer thesis]. University of Žilina. Faculty of Mechanical Engineering; Department of Transport and Handling Machines. Tutor: prof. Ing. Ľuboš Kučera, PhD. Degree: Engineer (Ing.), 2020.The diploma thesis 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. Out of a three proposed variants, a variant with a scissor construction and a hydraulic drive is chosed. 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. The result of the work is a engineering design of a lifting device weighing up to 3,5 tons, a drawing of the assembly and a drawing of a selected part.Keywords: engineering design, lifting device, scissor construction, hydraulic drive.
