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.

Inovace v oblasti plně mechanizovaných technologií a jejich uplatnění v provozu
Suda, Ondřej
This bachelor's thesis deals with the innovation of fully mechanized technology that has been introduced in forestry since the beginning of the 21st century up to now. The goal of this work is to summarize the data on the development of harvesters and forwarders, to determine their characteristics and present the ways how the innovation of this machinery affects its daily operation. The main directions of development that can be seen in this branch of engineering are reduction of pressure on the soil surface and of the damage to existing forest stand, reduction in emissions, improvement in the working conditions, increased power and workforce efficiency. This thesis focuses on harvesting and forwarding machines, their innovation and practical utility.
