The design of a mobile wheeled chassis
Král, Filip ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This thesis is concerned with designing the construction of a mobile wheeled chassis for transport machinery to specifically forwarder. The proposed construction is modeled in Autodesk Inventor . The proposed solution is checked by analytically functional computation and control by strength calculation too . On the basis of the proposed construction design is created drawing documentation , which include selected parts of the chassis .

Crawler chassis for a forwarder
Beránek, Jakub ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis is focused on using different types of caterpillar tracks with effort to minimize pressure of vehicle on forest land and keep the required speed and traction. The fractionation of undercarriage and evaluate of their abilities is provided in this work. After that, the process of deploying tracks and process of tensioning tracks is described. In the end the conceptual design of undercarriage is conducted

Handling equipment for forestry
Martinec, Patrik ; Pokorný, Přemysl (referee) ; Hloušek, David (advisor)
This bachelor thesis is focused on a research treatise on a forest fleet. The beginning of the work outlines the historical development of machines in the woodworking industry, it also deals with harvesters and their individual division according to specifications. The work also focuses on important parts of the harvester such as the hydraulic crane and harvester head. In the same spirit of comparison and division, export tractors are developed in the work. The chapter of the last work summarizes wheel loaders and their use in the woodworking industry. At the end of the thesis, the individual goals and outputs of the bachelor's thesis are evaluated.

Crawler chassis for a forwarder
Plichta, Zbyněk ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The first part of the bachelor´s thesis introduces crawler chassis used in forwarders and harvesters, its second part includes a concept design of a crawler chassis for a forwarder based on the given parameters. The design concentrates on the arrangement of the undercarriage and the choice of suitable track and idlers. Another intention of the design is to find an appropriate solution for suspension of bottom rollers with a sufficient travel, while observing small dimensions of the undercarriage. The outcome of the thesis is a drawing of the designed crawler chassis.

Powertrain systems of forest machines of the CTL technology
Janík, Richard ; Malášek, Jiří (referee) ; Mergl, Václav (advisor)
This bachelor's thesis contains a research analysis of drive systems of forest machines of harvester technology. At the beginning, harvester technology machines and their functions are described. The next chapters deal with the drive systems of these machines. The main topic is hybrid drive systems, which are divided into individual categories in this work, and diagrams of drive systems of specific harvester technology machines are created and described.
