Travelling crab
Pokorný, Emil ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This thesis deals with calculation and proposal hoisting mechanism of travelling crab with lifting capacity of 25 000 kg. In this thesis are proposed elements of rope system, which include rope, pulleys and rope drum. Part of the thesis is also the strength calculation of the sheave block and proposal of individual components of the lifting mechanism drive such as engine, gearbox and brake. The output of this thesis is a drawing documentation including drawing of the sheave block assembly and drawings of selected details.

Road and tram bridge
Vošček, Martin ; Štrba, Michal (referee) ; Brosch, Petr (advisor)
The subject of this Diploma Thesis is to develop different alternatives of the road and tram bridge. It is a river bridge with the length of 52,5 m. There are compared two proposals, while in the first proposal it is an arch bridge with the tension bars. The second proposal which is also finalized as the winning proposal is the truss structure. Both proposals have composite deck. The structure is designed from steel S355 and concrete C35/45. The load bearing structure is designed in accordance with applicable technical standards.

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.

Bridge crane two-girder
Vajmar, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis describes the design of two-girder overhead crane. At the beginning of the work are designed sectional characteristics of the girder and the crossbeam. Furthermore, they are calculated loads applied during crane operation. Following the determination of the static load and fatigue strength. All calculations are solved with respect to relevant standards relating to overhead cranes. The work also includes analysis of purchased components, which are geared motors, bumpers and drive (no drive) wheels.

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.

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.
