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.

Porovnání přenosu vertikálního zatížení od kolových a pásových sklízecích mlátiček
TKADLEC, Jakub
This diploma thesis deals with the comparison of the transfer of vertical load from wheel and belt combine harvesters to the soil. The load that the work deals with is for separate combine harvesters without an attached adapter. The aim of the work, was to create a database of vertical loads under the wheel or crawler chassis of combine harvesters, including the determination of the parameters of self-propelled combine harvesters. The calculated, measured and determined data were then included in graphs and tables with graphical representation of the load. The resulting data from the tables can also be used for computer simulations of soil loading under combine harvesters with wheeled or crawler chassis.

Porovnání přenosu vertikálního zatížení od kolových a pásových traktorů
ŠÁLENÝ, Miroslav
The work deals with the comparison of the transfer of vertical load from wheeled and crawler tractors to the ground. Only the tractor itself without the implement is considered. The aim of the work is to create a database of vertical load transfer under the individual axles of wheeled and crawler agricultural tractors and to collect other parameters of the measured equipment. The data will be able to be further used for computer simulation of soil compaction after the crossing of agricultural machinery.

Využití traktorů s pásovým podvozkem v podniku zemědělské prvovýroby
KRÁL, Martin
This diploma thesis deals with the use of powerful tractors with tracked chassis in agricultural primary production. For my work I chose Farma Pokorný Kmetiněves s. R. O., Which uses Challenger MT865E crawler tractor and BOTEP PLUS spol. s .r. o., which uses CASE IH STX 450 Quadtrac tracked tractors and CASE IH STX 480 Quadtrac. Literary review deals with the construction of wheeled and tracked bogies of tractors. The thesis describes the utilization of tracked tractors in given companies during the marketing year and analysis of the performance of individual tractors. The thesis is supplemented with characteristics of enterprises, description of technical parameters of individual machines and analysis of investment and operating costs.
