Posouzení různých způsobů soustřeďování dříví v podmínkách Malých Karpat
Murín, Ondrej
The key topic of this bachelor thesis is the evaluation of various mechanization equipment within the mechanized method of skidding in the Little Carpathians and a discussion of their economic and technical indicators, and ergonomic demands of their operation. The theoretical part of the work deals with the issue of damage to the forest ecosystem by mechanization equipment, the energy intensity of work for operating workers, and the characteristics of the used methods of skidding. The practical part of the work contains the results of measuring the quantities contained in the above issues in addition to other important indicators, such as time observation and economic inputs and outputs. The measured values are evaluated and compared with each other according to the set criteria. In conclusion, the author assesses the possibilities of using the mentioned mechanization equipment in the conditions of the Little Carpathians.

Analytická studie soudobých mechanizačních prostředků pro zemní práce v LH
Václavek, Tomáš
The bachelor thesis deals with an analytical study of parametres of mechanization machines for earthworks and their factors of application in forestry activities. The technique for earthworks is described in technical literature, where the typical features of different groups of mechanization machines for earthworks are described with differentiated utilization. The practical part compares the parameters of the earth moving machines, where their characteristic factors are taken into account when performing earthworks in forestry. On the basis of appropriate criteria, the technical and economic parameters are compared with a model study of selected earth machines, such as the Locust 752 front wheel loader and the Neuson 3003 miniexcavator, while repairing the model forest path. All aspects of practical research are described in the methodological section. The final part evaluates the parameters of machines for earthworks and also technical-economic results in the repair of the model forest path.

Mechanizační prostředky pro údržbu komunálních ploch
Buzinis, Jiří
The bachelor thesis presents a comprehensive view of the maintenance of communal areas with an emphasis on the use of mechanization means. A model of municipal area care plan is demonstrated on the model area and the possibilities of using mechanization means for working operations of individual technologies of maintenance care for partial paved and unpaved areas of this area are presented. The work is supplemented by a situational plan of the model area, which also serves as a map layer for the care plan for the given municipal area.

Využití mechanizačních prostředků pro zemní práce v zahradních realizacích
Jablecký, Lukáš
The thesis deals with the most common soil operations in any garden realizations. These operations are clearly defined and each operation is briefly characterized by suitability and usage order. These works are basic and also more specialized connected with garden realizations and green maintenance. You can find here the most common machineries, always from the "mini" and "maxi" category. Also tables of their power and technical information or photographs are attached. In the end, there is the ready-to-use pricelist of both variations and also the table contains the most suitable machineries separated for every single variation with comparison the time and the most economic uses of stated machineries.

Využití databáze mechanizačních prostředků pro hodnocení nákladů na údržbu vybraných parkových ploch
Čech, Marek
This thesis is focused on costs of machinery operations used for public green maintenance. The literary part describes the methodology and calculations of all costs related to the work with machinery, and it also includes the information about maintenance costs for chosen types of vegetation in public green. Results of this work were applied in the chosen area -- II. Building District Ostrava-Poruba where we can find all typical types of vegetation of public green in czech cities. Calculations of costs of grass mowing and leaf removing in spring and fall were compared with real costs of those services which were offered by a company which succeeded in the competition. This comparison gives an information to the municipality about real costs of those services, and about possibilities of costs saving if the municipality would do those services on its own.
