Constructive-technological project of building polyfunktion house locality Nova Nitra
Malý, Filip ; Ing.Lumír Kliš (referee) ; Diaz, Yvetta (advisor)
The content of this thesis is the construction project of technological multifunctional building new locality Nitra the Slovak Republic. Individual points outline the project, which are dealt with in this thesis can be divided into subcategories, depending on the type of information provided. The first category can include items such as a technical report to the STP, which describes the basic information about the objects constructed building including the construction situation, location of the site including links to transport and technical infrastructure and rough timetable for the construction of all buildings. The second category can include no specific calculation and optimization outputs such as itemized budget polyfunctional house SO-07.03, drawing of the site including all buildings proposed site and their economic evaluation, sizing of utilities for supplying water and electricity construction site, design of building machines and mechanisms including determining the time of deployment, technological regulation for the implementation of monolithic roof structure, including financial balance sheets prepared by the deployment of slab formwork. The last category included in the thesis are legislative requirements that must be observed and kept in the course of the construction plan is constructed as a safety and health at work, including security risks drawn up, inspection and testing schedule for monolithic construction and a list of environmental risks that may arise during implementation.

Bucket elevators
Žák, Zdeněk ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
This bachelor thesis deals with the transport equipment using as the main transport element buckets. To specify this is a device type of elevator, conveyor, digger and excavator, including companies producing these devices. Further work is focused on theoretical and technical approach to calculate where the theoretical part of the thesis deals with the mathematical expression shape layers and logarithmic spiral and in the technical part calculations required to design and determine the parameters of devices. The last section is an overview of transported materials.

Evaluation of performance of different size excavators
MACH, Milan
The aim of my thesis titled Evaluation of performance of different size excavators was to select five excavators ranked in different weight categories and subsequently to compare their actual performance. I monitored the actual length of one cycle on the basis of which the real performance of each excavator was determined. These results were mutually compared and summarized.

Determination of the actual output of excavators depending on the performed technology
ŠŤASTNÝ, Vladislav
The objective of this bachelor thesis is to determine the actual output of excavators, depending on the performed technology. For this purpose five excavators of different weights and different operating bucket capacity were selected. Measurements during different work activities led to identify the actual work cycle of excavators and the actual efficiency was subsequently determined by calculating. Analysis of results determined factors which influence the work cycle time to some extent and thus the actual efficiency of the excavator.

Length determination of working cycle of excavators at different technologies of working operations at the construction sites and the correctional proposal coefficients for calculation of real productivity.
BRABEC, Martin
In the bachelor´s thesis are stated values of working cycles of excavators at different technologies of working activity at the construction. Based on the basis of data and observing working technologies, the worked up proposal reflects correcting coefficients for calculation of real productivity. The study contains analysis of working materials of machines for ground work, analysis of fundamental kinds of ground works on construction states, analysis of excavator shovels and analysis of excavators working tools. In the second part, there are factors that influence productivity and there are determined remedial coefficients for calculation a real productivity. Further, in this thesis are compared of theoretical and real productivity observed by excavators. The results compare different excavator categories according to their size. In the ending of this thesis, there are determined the proposals and the principles for optimal usability of excavators at the construction.

Technology verification excavators in earthworks
FIKOTOVÁ, Petra
This thesis on the topic of Technology verification in the field of wheel excavators and its excavations in the first general part deals with the analysis of the work carried out on the construction site. Wheel excavator analysis tools have been developed and used. The study included ?wheel excavators and the technical parameters and analysis with the binding on the size category of wheel excavators?. The second part of the work deals with the evaluation of the results of the data collection for the determination of the actual times of working wheel excavators; and resultant cycles, depending on the work carried out. In addition, there are factors that affect the intended performance wheel excavators and how it works in the implementation of specific operations. Part of the work is the determination of the values of the correction coefficients for the calculation of the actual performance and the determination of the actual wheel excavators, and subsequent analysis of the excavators? performance dependent upon carried out working operations. In conclusion, on the results gained from the analytical process, proposals and guidelines for the optimal use of wheel excavators within the construction industry have been attained.

Analysis of working cycles of excavators in accordance with different variants to be done in constructions
KUČERA, Richard
The subject of this bachelor work is an analysis of working cycles of excavators in accordance with different variants to be done in constructions. That mainly describes variours kinds of excavators and their working tools in a accordance with works to be done in constructions. This subjekt further determines collection od data to assess a real time of working cycles. The next point of the bachelor work refers to factors which influence efficiency of excavators. The last part of the work determines principles and proposals for machines to be optimumly un-tilized in constructions.
