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.

Design of lifting gear of bridge crane 50 tonne
Koutný, Pavel ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
The submitted bachelor thesis deals with the design of a lifting gear for a bridge crane on 50 tonnes. The first part includes a design and a calculation of a rope, rope pulleys, design of a block and a cable reel. In the second part there is chosen an electromotor, a transmission, a brake, a clutch and bearings. Relevant strength calculations of a cable reel and a cable reel bolt are made for the capacity of 50 tonnes. The output of this bachelor thesis is a drawing documentation of a cable reel and a manufacturing drawing of reel components.

Autonomous vehicle for a material flow
Ryza, Vojtěch ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The focus of this bachelor thesis is a construction plan of autonomous truck for transporting EU pallets, which has a specified load weight. The concept is based on critical searches of similar autonomous trucks. Design is created in program SolidWorks 2019 and it is based on my calculations. The truck has prefabricated aluminium construction. Another device in the form of a roller track is offered on the back of the trolley.

Belt conveyor for gravel
Zeman, Vít ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The bachelor's thesis deals with the design of a belt conveyor for the transport of gravel. The used machine parts occurring in belt conveyors are analyzed here. The work contains a computational part focusing mainly on the design of drive power. The conveyor is composed of existing manufactured components, as well as components designed by me. The resulting design of the belt conveyor is modeled and described by assembly drawings. The work focuses on belt cleaners. Their possible location and construction are discussed in the research part.

Slot adjusting mechanism of cone crusher
Huňka, Jan ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
This master’s thesis deals with the obtuse-angled cone crushers especially about design of the individual parts of the adjustment mechanism. Most space is devoted to functional calculation and subsequent technical construction of the new design of obtuse-angled crusher where the output setting is adjusted using the motion thread and hydraulic locking system for compensating the thread clearance. The parameters are chosen with regard to the already established older types of cone crushers produced by PSP Engineering, a.s. An inseparable part is the calculation verifying the functionality of the motion thread and gearing. Another essential part of this work are stress analysis of the slot adjusting mechanism design using finite element method and considering two states - adjusting of the slot and crushing itself.
