Alternatives of lifting platform
Machala, Petr ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor thesis deals with the construction design of a platform lift with a mechanical drive, load capacity up to 3 000 kg and maximum height in folded state 250mm. In this work a suitable variant of stroke mechanism and analysis of the use of selected options of mechanical drives is selected. In the next part the appropriate calculation of the mechanisms regarding the chosen dimensions and loads is elaborated. In the end the technical possibilities of both variants are evaluated and compared. The output of this work is the assembly drawings of the platform lifts for both types of drive.

Frame of stationary hydraulic device
Klezla, Vojtěch ; Pokorný, Jan (referee) ; Pokorný, Přemysl (advisor)
The subject of this thesis is design and strength analysis of stationary hydraulic device. Strength analysis is made by the finite element method. The thesis describes design of used frames, profiles and other components, which are parts of the frame. Frame modification is proposed, based on the results of the strength analysis. These modifications are checked with strength analysis. The thesis includes drawing of weldment. The project has been carried out in cooperation with Bosch Rexroth, spol. s. r. o.

Stroke mechanism of crane trolley
Malár, Martin ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the stroke mechanism of the crane trolley, maximum weight of loads is 16 000 kg. The work is divided into two parts: a written part and a practical part. In the written part of this work there are the main dimensions of lift and control cable drum strength solved. The calculation is subject to quantities that are given by assignment. Choice of the electric motor, gearbox and follow-up control of the stroke speed according to customer requirements is discussed further. The second part includes production drawings, in which are included the total set of the stroke mechanism and other assemblies and production drawings.
