The aim of this thesis is to design a clamping unit with mechanical multiplier. Unit will serve as a technological clamping element in the technical equipment. My task was to select the method of construction and design driving main unit for grip jaw. I chose a solution with a mechanical multiplier. The frame unit is made up of fixed and sliding clamping jaw and is self. Unit is designed as a built module. The entire structure must be designed to meet the initial parameters specified in the award of thesis. The main parameters include clamping strength of 80kN, the extent of working stroke 15 mm and the size of a scroll, which is 250 mm. They are also listed in the award size constraints: the length, width, height dimensions and the coupling unit.
