Mobile wheel cranes
Matula, David ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
The aim of the thesis is introduction of mobile crane and comparison of individual models from different manufacturers. The first part is devoted to the history of cranes. Other types of cranes are mentioned here as well. In the main part are mentioned systems that we can encounter in cranes. At the same time, it categorizes cranes of the world's leading manufacturers according to the main technical and dimensional solutions. The third and last part of the thesis, is trying to estimate development trends.

Static solution of the ceiling structure of apartment building
Habanec, Kamil ; Nečas, Radim (referee) ; Zich, Miloš (advisor)
The Bachelor thesis deals with the static solution of the ceiling construction of an integrated apartment building. The aim is to design, or change the sizes of the projected structures in the submitted project, to ensure the interruption of thermal bridges and protection against foot noise. Subsequently, their static solution, dimensioning and assessment to marginal states. The elements intended for the solution are ceiling structures above the second upper floor, beams, a connecting staircase and a column. The calculation of internal forces was performed in the student version of SCIA Engineer 20.0 with a comparison of values on an independent simplified model. The work also includes drawing documentation for the aforementioned elements. The calculation was carried out according to the applicable standards and principles.

Frame bridge
Kapsa, Štěpán ; Velešík, Marek (referee) ; Koláček, Jan (advisor)
The work deals with the design of a single-pole frame structure of a road bridge, which is based deeply on piles. Due to the size of the span of 26 m, additionally prestressed cables are designed in the supporting structure. The structure is analyzed by a three-dimensional bar model and assessed for serviceability and load-bearing limit states in the longitudinal and transverse directions. Part of the design is a study of the influence of supporting the computational model and a comparison of the effect of active and resting earth pressure on the structure.

Diagnostics of Reinforced Concrete Bridge
Rozbroj, Lukáš ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This thesis contains diagnostics of a reinforced concrete girder bridge in the municipality of Újezd u Brna. The aim is to conduct an inspection of the bridge, gather quality photo-documentation of defects and failures and design and conduct a diagnostic examination of such extent that would be necessary for judging the load bearing capacity of the bridge. The result of this thesis is the determined load bearing capacity and a proposal of measures required to keep the bridge functional.

Travelling Crab
Kolář, Jiří ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
Thesis covers the basic calculations for the design of the basic dimensions of the lift mechanism of travelling crab to load 30,000 kg, strength calculation parts of the hook block such as pulley bolt, beam and side rod, as well as draft propulsion. The last part is the design documentation of assembly drawing of the hook block and detailed drawings of selected components.

Reconstruction of the road bridge near the village Holýšov
Svoboda, Adam ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The thesis deals with design of strengthening of existing bridge structure near the village Holýšov using modern method of additional presstresing. The bridge over the river of Radbuza is h-shaped beam bridge, which was built in 1924. In the present state its load capacity is under the limits for bridges situated on first-class roads. Original documentation of the bridge does not exist, the main source of information about construction details is the diagnostics research. The method of reinforcement by post-tensioning by cables in substituted cable ducts is highly efective in terms of the incerease the load capacity of existing bridge structure. The design of strengthening and the final load capacity was verified by static calculation.

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.
