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.

Crane hook block - lifting capacity 25 tons
Šanca, Kristián ; Trčka, Tomáš (referee) ; Malášek, Jiří (advisor)
The crane block is the lower part of the hoist. It is designed to fulfill a load capacity of 25,000 kg, while being safe and as light as possible. The work describes the principle of the hoist. A design solution is chosen in which two ropes are wound on a drum. The calculation of the hoist is in the calculation part, the components of the hoist are further described and calculated, using basic strength calculations. Attached is a drawing of the assembly and important details.
