Design of mini backhoe
Vorlíček, Vít ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The aim of the bachelor thesis is to design a small tractor backhoe and aggregate it into a three-point suspension system with a maximum tearing force of at least 20 KN. This thesis is divided into six chapters and it deals with the division of excavator equipment, parts of excavation and analysis of competition, alternatives of design solution, design of own concept, functional calculations and strength calculations.

Additional working equipment and tools for earth-moving machinery
Švrček, Jakub ; Hloušek, David (referee) ; Škopán, Miroslav (advisor)
Bachelor thesis deals with explore attachments for earth-moving machinery produced in present time, especially for loaders and excavators. Bachelor thesis has critical research form and his task is to create inventory of tools and equipment, which is used for expanding ver-sality. Next task of bachelor thesis is referring to basic construction principles, typical oper-ating properties and ways of future development. In thesis are described equipment intend-ed for some earthworks, especially earth-drills, trenchers and backhoe attachment. In thesis are described some additional equipment for maintenance and repairs roads, which covers equipment like plate compactors, roller compactors and snow blower and snow blades.

Size segregated atmospheric aerosol in selected workspaces of coal strip mine
Basslerová, Barbora ; Hovorka, Jan (advisor) ; Svoboda, Petr (referee)
The workers are exposed to aerosol particles in a coal strip mine. These particles are usually generated by the Bucket-wheel excavators which break the mined rock. The goal of the thesis thesis was to compare the concentrations of atmospheric aerosol particles - PM on the Bucket-wheel excavator Schrs 1320, the Stacker ZPDH 6300 and the Bucket- wheel excavator K 800/N2 in the coal quarry Doly Nástup Tušimice, and then to answer the questions what is the main cause of increased concentration PMx and whether the mining machines are different from each other. The measurement was realized stepwise on every mining machine in the time period from 12. 8. to 2. 9. 2016. The concentrations of PM1, PM2,5 and PM10 were measured by two portable laser nephelometers in the cab drivers and the outdoor walkway of the mining machines with the integration time of 1 minute. The air temperature and the relative humidity were monitored in both types of settings in every five minutes. The PMx concentrations variability is usually determined by the type of work and by the type of smoking. Consequently, PM concentrations on the mining machines were compared at the morning exchanges and evening exchanges, during the outdoor cleaning by sweeping, the indoor cleaning by hoovering and during the smoking. The highest...

Drop hammer for driving spindle
Svatoš, Ivo ; Vepřek, Milan (referee) ; Škopán, Miroslav (advisor)
Thesis deal with design of drop-hammer and especially its carriage (frame) for direction equipment for driving various thin-walled profiles in civil engineering. The entire drop- hammer is used as an additional adapter for construction machine. The first part of thesis contains design options, description of chosen option, including principles of work with drop- hammer. It also contains the calculation which are important for design of parts of drop- hammer, frame strese analysis by computer software, the approximate production coast of drop-hammer and summary of the parameters of the final product. The annexes contains the specified drawings and examples of 3D models of assemblies.

Design of excavator
Brza, Lukáš ; Zdařil, Zdeněk (referee) ; Křenek, Ladislav (advisor)
The design of the excavator follows requirements of machines for demolition work. The excavator is equipped with an innovative type of under carriage, which not only increases mobility over the demolition sites but also the visibility from the driver’s cabin. The components of the excavator, that improve the demolition work, are special types of tracks, suspensions and articulated steering. Tracks can change their shape to increase the stability and also to adapt to the diff erent types of ground. The suspensions with tracks are able to adapt to the terrain thereby they lighten the asperity. Suspension can also tilt or even raise the excavator and thereby increase the angle of visibility from the cabin. This function is necessary mainly when taking down higher constructions. Articulated steering is a new function that has never been used for excavators. This steering was chosen due to fl exible movement over demolition sites. The main aim of the project is to create a new design of the excavator, but more importantly to distinguish the excavator from the excavators already on the market, with regards to its esthetics and under carriage innovation.

Constructive technological project of block of flats in Strážnice
Rozumek, Jakub ; Kopecký, Lukáš (referee) ; Diaz, Yvetta (advisor)
The theme of my diploma thesis is Building and Technological Project for a residential building in Strážnice. This is a study of the implementation of major technological stages of object SO- 01 residential building, the project concerning the construction site installation, design the mechanical assembly, traffic solutions, technological process earthworks, foundation structures, piles CFA and reinforced concrete ceiling construction. The work includes further object schedule, financial plan, a detailed timetable for construction of residential building, the budget, the inspection and the test plan, safety hazards on a construction site in the implementation of the substructure object and thermal technical assessment of selected structures.
