Mechanical screens for a small hydropower plant
Krejčí, Monika ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The first part of this bachelor thesis contains a short summary and overview of different types of screens. The main goal of this thesis is the calculation of selected parts of hydraulically driven screens and the part of this thesis is also the design of hydraulic circuit. The thesis is attached by drawing documentation of selected parts of mechanism.

Hydraulic rake screen
Růčka, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
This thesis deals with the structural design of hydraulic raking screens placed before a sewage treatment plant. The first part describes various possibilities of water treatment from individual particles. The second part deals with basic parameters of screens and calculations of propelling power for previously chosen structure. Furthermore, a strength check of structure under the most unfavourable load is performed. Drawings of the whole assembly of hydraulic raking screens, plus a few selected components are attached to the thesis.

Lift positional table
Solovský, Jakub ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
This bachelor thesis is focused on functional strength calculation of scissor lift mechanism, which serves for transporting loads of a weight 500 kg situated on a pallet. Required lift height is from the first position 0,75 m to the second 2,5 m above the ground. There are mentioned engineering design, calculation of roller conveyor drive, dimension of lifting mechanism and concept of linear hydraulic motor in particular parts of the thesis. Other part of this thesis is drawing documentation.

Hydraulically driven screens
Forman, Ladislav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main objective of this work is the calculation of selected parts of hydraulically driven screens such as cleaning equipment before entering the small hydro power plants. The thesis is divided into two parts. The first part focuses mainly on the calculation of hydraulic mechanism for cleaning screens. The second part contains a drawing of the general assembly hydraulically driven screens and sub-assemblies.

Design of lift positional table
Vajmar, Jan ; Malášek, Jiří (referee) ; Pokorný, Přemysl (advisor)
This bachelor’s thesis describes the design of a lift positional table for loads of a weight 750 kg and stroke positional table 1000 mm. At the beginning of the work is a brief analysis of the problems of lift positional tables and choice of design solutions. In addition to addressing the drive tray pallet on the table using the roller track. It addresses the dimensions of the scissor mechanism, its load, stress control and design of the actuator stroke. The work also includes drawings.

Hydraulic linear drive for paralell kinematics structures of robots
Hrbáček, Jakub ; Holub, Michal (referee) ; Knoflíček, Radek (advisor)
This master’s thesis deals with the design of hydraulic linear drive for parallel kinematics structures of robots, which is not standardly used for these kind of robots. In the part of background research it deals with modern applications of these robots in profession and possible construction components, conventional or nonconventional ones. The master’s thesis further describes the procedure of construction the hydraulic drive. At first the linear hydromotor is designed and further the whole hydraulic circuit. The whole drive is processed in appropriate software program as a 3D model, from witch the assembly drawings is worked out.
