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.

Double Box Girder Bridge Crane
Vlachovič, Tomáš ; Cupal, Vladimír (referee) ; Pokorný, Přemysl (advisor)
The diploma thesis deals with the assessment design of two-girder crane bridge for the lifting capacity 50 tons. Span of the crane is 20 meters, wheelbase is 3.15 meters and lifting height is 7 meters. This diploma thesis deals with the numerical solution box beam and using the finite element method is solved buckling. The diploma thesis has been elaborated using the relevant technical literature and standards that contain procedures and recommendations for calculation and designing of bridge cranes.

Overhead travelling crane 125t
Peprník, Pavel ; Zimola, Lubomír (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with the assessment of drafted steel construction of overhead travelling crane by using finite element method. The crane’s lifting capacity is 125t/32t. It is going to be placed in hall of Slovácké strojírny, a. s. in Uherský Brod. Span of the crane is 25.8 meters, wheelbase is 6.7 meters and lifting height is 17 meters. My work contains analysis and assessment of crane construction with a load of fatigue according to ČSN 27 0103.

Mechanical analysis of the subsystem of the tower crane
Urbánek, Roman ; Venský, Jiří (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis deals with the solution of a subsystem of a tower crane with a passive effect (NNTP). First part describes tower cranes and their parts. The following part is a description of the theoretical and physical laws of statics and dynamics. In the practical part, various states of motion of a specific modeled subsystem are calculated, which shows a trolley of the tower crane. The aim of the calculation of each configuration is to determine the numerical values of the contact forces in the links, to analyze the dynamic quantities and to evaluate the functionality of the links. Numerical values of unknown parameters were calculated by solving a system of linear equations in the calculation software Matlab.

Determination of the risk elements and other elements concentration in animal feed
Křehlíková, Jana ; Juglová, Zuzana (referee) ; Diviš, Pavel (advisor)
This thesis deals with the determination of selected microelements and macroelements and risk elements in dog and cat food. The theoretical part describes the nutrition of dogs and cats and focuses on the safety of the food in the context of contamination with risk elements. Another topic discussed is the chemical analysis of feeds, specifically the determination of nutritionally important substances, beneficial elements, and contaminants. The experimental part deals with the preparation and digestion of feed samples and the subsequent analysis of these samples using ICP-OES and AAS methods. The detected concentrations of the elements of interest in the feeds were compared with the feed standards issued by the Department of Veterinary Medicine and the decree issued by the Ministry of Agriculture. The analysed feeds were found to be deficient in some elements. The content of the risk elements in the feed met the legal limits and did not pose a health risk to the animal. Elements for which the legislation does not provide a maximum permissible limit were present in the feed-in in high concentrations that could already harm the animal's health.

Overhead crane - design of crane trolley
Brzobohatý, Petr ; Čížek, Karel (referee) ; Škopán, Miroslav (advisor)
The diploma work deals with design of lifting mechanism of overhead crane trolley with a load capacity 200 t. The main objective is design and analysis of selected components of lifting mechanism and components which are directly associated with lifting mechanism. Work includes design elements of a rope system, such as rope, rope drum, sheaves, sheave block, elements of the proposals of propulsion, such as engine, transmission, brake, coupling. The work contains also strength calculations of some components and drawing documentation.

Industrial hall
Forman, Radek ; Buchta, Stanislav (referee) ; Bajer, Miroslav (advisor)
Two-bay hall for warehouse and manufacturing purposes with supporting steel structure and thermally insulating sheating with width of 36 metres and lenght of 72 metres. The hall incorporates two overhead cranes with maximum load of 32 and 40 tonnes. The main supporting structure is a system of plate girders and beams. The beams are connected with hinges and are placed with intervals of 6 metres. The hall design is intended for 1st snowing area

Bridge crane one-girder
Stanec, Stanislav ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with constructional design and a calculation of one-girder bridge crane with the requested primary parametres: lifting capacity 10 000 kg, span 12 000 mm, wheel base 2 500 mm, travel height 7 000 mm. In diploma thesis, there is executed analysis of constructional designs of box girders, drawn up technical report with the analysis of the choice of the construction with important technical and physical calculations. Calculations were executed according to valid Czech state norms and literature. Drawing documentation is enclosed to this thesis.

Conceptual design of portal crane 4 tonne
Lopata, Zbyněk ; Malášek, Jiří (referee) ; Kubín, Martin (advisor)
In my bachelor´s thesis I deal with a concept suggestion of portal crane with a lifting capacity of 4 tonnes. The bachelor´s thesis is aimed at suggestion of basic parameters of crane, hoist, main girder, shorings, rails, travelling wheels and travelling bears. Bachelor´s thesis also contains control calculation of construction of crane and travelling bears. In practical part of thesis drawing of crane and three dimensional prototype of crane is claused.
