Travelling Crab
Komůrka, Martin ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This thesis deals about engineering design and calculation hoisting mechanism of travelling crab for capacity 20 000kg and lift height 36m. For this task are made necessary calculations concerning hoist, crane cable, cable pulleys, cable drum. Further, they are drawn strength calculations pin of pulleys, sidewalls, crossbeam and crane hook. Then is also set a drive part of hoisting mechanism consisting of calculation and choice motor, gearbox and brake. The result of this thesis is drawing documentation of pulley block and manufacturing drawings of individual parts.

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.

Bridge crane one-girder
Chroust, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
The focus of this thesis is the construction of a single girder overhead crane. The goal is to render a crane construction according to preset parameters. The parameters include a lifting power of 8,000 kg, a 10,000 mm reach, a 2,400 mm wheelbase and a stroke of 8,000 mm. The thesis includes brief theoretical research focused on overhead cranes, their various types and description of their main components. Brief description of chosen parameters for the construction itself follows. The description of chosen parameters includes calculations of strain acting during operation, technical and stability parameters, essential for the construction. All calculations were made with regard to valid Czech technical standards and specialized literature which focuses on the construction of cranes and their parts. Finally, the thesis is extended by the required technical drawings.

Timber foot bridge over a wolf run
Mynaříková, Alice ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
The subject of this diploma thesis is the construction of a timber foot bridge over the wolf run in the Šumava National Park. The total length of the bridge is 240 m with two ground plan bends. The foot bridge includes three viewing decks, two of which are covered with shed roofs. The foot bridge is divided into 16 segments. Each segment is 15 m long with a width of 2.2 meters. The ground plan dimensions of the viewing decks are approximately 15x7 and 15x11 m. As the main structural material has been chosen glued laminated timber of the strength class GL28h, other elements are made of solid timber of the strength class C24. The thesis includes an introductory document, options analysis, technical report, static analysis, bill of material and drawings.

Bridge crane one-girder
Malár, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis is focused on the construction design of one-girder bridge crane for the LUVE – PLAST company. Construction design of the crane was developed in cooperation with the K-TECHNIK company, which carried out the production and installation of the crane bridge and the crane runway. The basic required parameters of the crane are: load capacity 8 000 kg, range 16 900 mm, minimum lift 4 650 mm. The crane, which construction is proposed in this thesis will be used for the exchange of forms of injection molding machines. The forms weight is about 7 000 kg. The aim of this work was to create a technical report with an analysis of construction choices solution with important technical and strength calculations. Calculations were made according to the Czech state standards and the literature dealing with the construction of bridge cranes. Further, the strength check of selected parts was made.

Bridge crane
Plášil, František ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with the design of an overhead crane. In the first part, the research of the current situation and description of individual parts has been made. It is followed by the choice of a suitable concept design with respect to the specified parameters. The following part describes important technical calculations for the structure of the crane. Calculations are made according to valid Czech state standards. In the final part, the calculation of the structure using the finite element method analysis is performed and the financial balance of the project is proposed. Last but not least, an assembly drawing of the crane and selected detailed drawings are attached.

The multistorey office building
Bílek, Tomáš ; Sýkora, Karel (referee) ; Šmak, Milan (advisor)
Design of a new steel structure administrative building in Zlín. Structure is consist of three parts. The part A is designed of three fields in the transverse direction and five fields in the longitudinal direction. This part is two-storey. The part B is designed of two fields in the transverse direction and three fields in the longitudinal direction. This part is six-storey (five-storey). The part C is designed of two fields in the transverse direction and five fields in the longitudinal direction. This part is four-storey (three, two-storey). In both directions in all parts of the building is the distance between the columns in all fields of 6,0 meters. Structural elevation of all floors is 3,5 meters. Shape and dimension design. Fixed, utility, climatic load. The purpose is confrontation of inner forces and dimensioning of main supporting elements in three variations of structure. Comparsion of variations. More detailed static calculation, drawings for the selected variant. Detailed drawings for part of building.
