Design of agricultural cutting machine
Hráček, Petr ; Chorý, Tomáš (referee) ; Zvonek, Miroslav (advisor)
This diploma thesis should bring not only working machine into the branch of agricultural industry, but also new approach to design. Obviously, the contribution of technical innovations, which are required in this segment, is concerned, too. All knowledge and concepts come from the practise of this field. The project partly takes up the pre-diploma thesis called Vision of the agricultural cutting machine with container arrangement and shares some details of the concept as such. The technical part was solved during the winter term within the scope of the subject Machines and equipment. From this project will be adopted all bases of constructional innovations of agricultural machine concept.

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.

Comparison of loudness inside and outside tractor's cabine
OPEKAR, Jiří
This bachelor's thesis is aimed at investigating the noise level in a tractor cabin and at certain distances from the tractor. Eleven tractors of different brands with power outputs ranging from 70 kW to 93 kW were selected for the study. The thesis outlines noise problems in general, the noise classification and sources, and examines the impact of noise on human health as well as the legislation concerning protection against noise. Further investigated within the study is noise in agriculture and in particular types of noise caused by certain parts of a tractor. Included are also basic tractor cab design parameters, its history, evolution and current state. The study presents characteristics of the examined tractors and describes acoustic pressure values measured inside and outside the tractor cabins. The values are presented in the form of tables and charts. Lastly, the values are compared for all the tractors within the study and the results are evaluated.

The workstation in the tractor cab.
LÍKAŘ, Ondřej
The thesis is focused on the operator environment in the tractor cab. More precisely, the noise and dust in the tractor cab when stubbleng, plowing and sowing carried out under the autumn field work. Measurements were carried out in five farmers as five different tractors similar performance. As reference was used Zetor 12145, which was compared with New Holland T6070 Tractor, Landini Powerfarm 100, 135 Zetor Fronterra and Deutz-Fahr M620. The results of all measurements were graphically displayed and compared each other. In conclusion, the results were compared to measurements with the legislation. The measurement spat out of the rear tractor does not exceed the noise limit, which indicates the legislation. Dust measurements was more indicative of the diversity of the weather.
