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.

Rozbor alternativního použití těžebně dopravních technologií u Lesního družstva Přibyslav
Zichová, Aneta
The objective of this diploma work is the use of mining transportation technology at the Přibyslav Forest Cooperative. The work deals with the overall characteristic of moto-manual mining, harvesting technology and the creation of criteria for their most effective use for forest crops. Suitable crop growth for the use of moto-manual mining was selected based on the following criteria: terrain type and edaphic category, economic method, minimum age and mining regulation. The selection of suitable crops for the use of harvesting technology was conducted based on the following criteria: terrain type and edaphic category, minimum representation of conifers, economic method, minimum age, mining regulation, type of chassis and the cut of the harvesting head. Furthermore, the work includes an approximate calculation of the mining expenses and bringing the wood closer when using harvesting technology and moto-manual mining as well as comparing the results of the individual technologies.

Posouzení vhodnosti použití harvestorové technologie lesní těžby na ŠLP Křtiny
Sysel, Jan
This thesis is focused on assessing the suitability of using harvesting technology in conditions of Training Forest Enterprise Masaryk Forest Křtiny (TFE). The work is related to the overall characteristics of harvester technologies in terms of technical solutions, but also to establish criteria of suitable natural conditions for the most thrifty deployment. The findings obtained in this investigation are applied to the forests of the property to discover the potential using options of harvester technologies. Criteria to determine the suitability of the forest stand were: type of terrain, edaphic category, minimum representation of conifers and age of stand. For forest stands there are assigned the appropriate types of harvester chassis and harvester heads which are suitable for their cutting. In the thesis there are further processed optimal harvester nodes, a comparing of the time consumption to processing of the volume of logging by classical logging technologies and harvester technologies. Based on the findings there was elaborated a recommendation for operating practices.
