Crane Hook Block - Lifting Capacity 20 tons
Štefanec, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
Task of this bachelor’s thesis is to propose a crane hook block with lifting capacity of 20 tons. Hook block is part of the mechanism of class M4 according to technical standard ISO 4301-1. It briefly describes what hook block is and summarizes the design solutions of individual structural units. In next part of the thesis there is a design and calculation of the most important parts of the hook block due to function. The content is also a choice of purchased components. Thesis appendices consist of drawing of the whole assembly, lists of items and drawing of crossmember.

Design of doublebeam of bridge crane 50 tonne
Matěja, Josef ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
The Bachelor’s thesis deals with the design of two-girder crane bridge for the lifting capacity 50 tons. The process is split in eight parts. The first one contains a preliminary scheme of the whole design and proposal of main parameters. The second part contains calculation of preloading of the girder, specification of its main dimensions and calculation of maximum bending moment. The other parts include calculations and designing of individual main parts and accessories such as crane girder, cross girder, wheels, rails, gear and brake. The bachelor’s thesis has been elaborated using the relevant technical literature and standards that contain procedures and recommendations for calculation and designing of bridge cranes.

Design of doublebeam of bridge crane 8 tonne
Bobčík, Martin ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with design of doublebeam of bridge crane (8 tonne). The purpose of this thesis is to design the main parameters of the crane bridge. First of all, I chose from the catalog wire rope hoist. I proposed preliminary dimensions of mainbeam and crossbeam. I made strength check of mainbeam and crossbeam. For attachment mainbeam and crossbeam I chose fitted bolts. I calculated required number of fitted bolts M12. From the standards I chose wheels. I checked the wheels to maximum contact pressure and service life. I chose bearings from catalog SKF. I checked the bearings to service life. I proposed dimension of shafts. From the rolling resistance and friction, I calculated the power output of the engine. At the last I proposed cable trolleys and control of the crane.

Conceptual design of semi-portal crane 8 tonne
Kučo, Stanislav ; Kašpárek, Jaroslav (referee) ; Kubín, Martin (advisor)
This bachelor’s thesis deals with a design of semi-portal crane. Firstly, it outlines the assignment, where the main parameters such as height and depth of the crane are determined. In the next part a proper rope hoist with appropriate engineering characteristics is selected. Then the design of the main girder follows. Its proportions are designated from the strength calculation, which are proved by check calculation. Another aim of this thesis is a project of the construction of the girder with a crossbeam, which is realized by fitted bolts. Their size is also calculated and controlled. Finally the carrying capacity of travelling wheel and control of the engine overloading is calculated.

Conceptual design of bridge crane 8 tonne
Franc, Šimon ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with conceptual scheme of a bridge crane with carrying capacity of 8 tons. Intention of this thesis is to scheme out the main specifications and size of this bridge crane. First of all we design and calculate the main bridge girder. Afterwards we calculate and design the cross bars and the travelling wheels. At last the desigh of an electromotor for powering the movement of the bridge crane takes its place.

Single-spar Travelling Crane MV 6,3/9
Čížek, Ondřej ; Pokorný, Přemysl (referee) ; Mynář, Břetislav (advisor)
Bachelor’s thesis will deal with single-spar travelling crane with under crane trolley, lifting capacity 6,3t. Aimed at design main structural parts, which I split to three main parts. First part will deal with design crane bridge, second part will design crosspiece and third part will design screw connection. In calculations and designs I keep to the ČSN standards and crane design literature. This Bachelor’s thesis was written by cooperation with Iteco company.

Description of machine tool frames.
Míčka, Martin ; Matějka, Petr (referee) ; Blecha, Petr (advisor)
This work describes the machine tool frames via background research. There are basic requirements for the frames included in this work. It is focusing especially on static and dynamic rigidity. Thereinafter you can find in my work all the ways of making the frames and also the materials which are used during their production. Last but not least I am presenting some examples of constructions single parts of the frame and all the ways of their attachment to the ground.

Travelling Crab
Bernard, Vladislav ; Špička, Jiří (referee) ; Malášek, Jiří (advisor)
This work dissert about proposal and calculation hoisting device travelling crab, intended for tonnage 50 000 kg. For this tonnage there're performed pertinent strenght calculations, concerning journal of pullies, side plate, crossbeam and crane hook. Part of work is proposal desirable electric motor, gear - box, brakes, jaw clutch and bearings. In work are also descriptions of hoisting apparatus and descriptions of construction parts of sheave block. Defined are also main dimensions ancillary components for desired hoisting. Work is finished with complete drawing documentation of sheave block travelling crab.

Design of bridge over Kyjovka river
Zlatuška, Karel ; Nečas, Radim (referee) ; Zich, Miloš (advisor)
The subject of Bachelor’s thesis is the design of the road bridge over the Kyjovka river on the Na Šlajsi street in Lanžhot. The work is focused on the detailed static analysis of the one span load bearing structure made of reinforced concrete. Two alternative versions have been designed and one of these was further assessed in the static calculation. The chosen version is a parapet girder composed of two main longitudinal members of variable section height. These girders are connected together with a deck slab which is supported by tapered cross beams. The theoretical span of the construction is 13 meters. The static model is created and solved in software Scia Engineer 2013.1 and its results are controlled manually according to the principles of basic structural mechanics and linear elasticity. Assessments are calculated by hand according to Eurocode. In the calculation only vertical load effects are considered.
