Tower Cranes Models Review
Kuděla, Jan ; Škopán, Miroslav (referee) ; Pokorný, Přemysl (advisor)
This Bachelor thesis is focused on tower cranes with a working range over 40 meters. These cranes are composed of specific sections. In the first part of the thesis a more detailed description of tower cranes is presented. Next topic, that is being discussed, is three structural types of tower cranes with upper turntable bodies that are being made nowadays. In the overview, present world producers of tower cranes are listed. Companies like Liebherr, Potain, Linden Comansa, Kroll and Raimondi are described in more detail. Lastly, different models of tower cranes from leading producers in selected parameters are being compared.

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.

Implementation of Registred Office of Company POLNA corp. s.r.o. in Třinec
Špilínek, Richard ; Venkrbec, Václav (referee) ; Nečasová, Barbora (advisor)
This master´s thesis deals with construction-technological project of administrative-production and storage complex in Třinec - Oldřichovice. It´s a new building of the main building, consisting of a two-storey administrative building and a one-storey storage hall, which is complemented by other sub-objects. The master´s thesis solves the realization of the building as a complex whole and in more detail focuses on vertical and horizontal supporting structures, made of steel elements and steel-concrete ceiling structure. An integral part of the project include studies of the realization of the main technological stages of the main building, technological regulations, complemented by assembly schemes, solution of transport routes and proposal of machine assemblies, site equipment design, time schedules, budgets, inspection and test plans and proposal of security measures for selected risks. The work is further supplemented by a specialized area that prepares the design and execution of intra-areal reinforced communications.

Design of doublebeam of bridge crane 8 tonne
Bobčík, Martin ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with design of doublebeam of bridge crane (8 tonne). The purpose of this thesis is to design the main parameters of the crane bridge. First of all, I chose from the catalog wire rope hoist. I proposed preliminary dimensions of mainbeam and crossbeam. I made strength check of mainbeam and crossbeam. For attachment mainbeam and crossbeam I chose fitted bolts. I calculated required number of fitted bolts M12. From the standards I chose wheels. I checked the wheels to maximum contact pressure and service life. I chose bearings from catalog SKF. I checked the bearings to service life. I proposed dimension of shafts. From the rolling resistance and friction, I calculated the power output of the engine. At the last I proposed cable trolleys and control of the crane.
