The goal of this work is a design of a hydraulic drilling unit and a manipulator for the PSU 9000 machine. The introduction describes the use of underground mining drilling machines and mentions some of the current solutions. The second part contains the design and calculations of individual components. In the final part, the finite-element method is used for calculation of the bearing parts of the construction.

The aim of this thesis is the design single purpose drilling machine. Single purpose drilling machine will be used for machining cast iron gearbox. In the first part of the work is carried out literature search of drilling machines and single purpose machines, the second part follows a design single purpose drilling machine.

The aim of this thesis is the structural design small drilling rigs for drilling wells. Drilling rig will be used for drilling wells up to 200 mm diameter rotary drilling technology with irrigation water. The first part is a literature search of small drilling rigs. In the second part, then custom design a small drilling rig.
