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.

Modular series of workshop mobile portal cranes
Novák, Tomáš ; Nezbeda, Jiří (referee) ; Škopán, Miroslav (advisor)
The Master’s thesis deals with the proposal of a modular series of workshop mobile gantry cranes with a load capacity from 500 kg to 3.200 kg. The introduction deals with the recherche, in which the workshop mobile gantry crane is firstly categorized according to the construction. Then, its parts are described in detail and at the end of the recherche, cranes with similar utility properties are presented. The main part of the work is focused on the proposal of the modular series, the proposal of the load-bearing structure and the strength calculations of the load-bearing parts. At the end of the work, there is a check of calculations according to the FEM model, an estimate of the crane price and a proposal configurator for a quick search of a required crane by a customer. The work includes appendices in which the parameters and calculated values of all gantry cranes of the module series are given.

Mobil cranes with lifting capacity from 200 to 1200 tons
Novák, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the development, construction and current types of mobile cranes with a load capacity from 200 to 1200 tonnes. The introductory pages of the thesis deal with the basic concepts in the field of cranes as well as with the brief history of the origin of these machines. The main part of the work focuses on categorization, introduction of the world's major manufacturers, a detailed description of the parts of the mobile crane, and the differences in the technologies used by the individual manufacturers. The manufacturers mentioned are companies Liebherr, Tadano Faun, Tadano Demag, Manitowoc Grove, Link-Belt, Sany and XCMG. The next part of the thesis deals with an overview of the individual manufacturers‘ concepts and their specific parameters. The last part of the thesis consists of several clearly arranged charts that compare the selected models according to their maximum load capacity, maximum hoist height, maximum radius, and other selected parameters. The thesis also includes chapters focused on the specifics of the operation and the maintenance of mobile cranes and determines development trends.
