Analysis of working mechanisms equipment of loaders and tractors for use in municipal services
David, Josef ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor dessertation is a review and analysis of complinental work equipment in municipal service. The thesis is primary concerned about smaller loaders and tractors in use of cleaning public areas and roads in summer and winter seasons. As a part of this dessertation is also review and comparison of snow plows, snow cutters and sweepers, concidering their mechanical principles, technical parameters and operational properties. This informations help with assumption for next development. In conclusion, this is a comparison of differences, wether complinental work equipment are meant for loader or tractor.

Strength analysis of the frame for forestry cable yarder
Kovařík, Radim ; Halámka, Tomáš (referee) ; Mergl, Václav (advisor)
This work is focused on the strength analysis of the frame of the Larix Lamako forestry cable yarder rope, as an additional device of a universal agricultural tractor. The theoretical part of the work is focused on the basic description, determination of the area of use of the equipment and the distribution of forest rope transport equipment according to several criteria. The practical part of the work deals with the analytical calculation of force action. Based on the force action, the strength analysis of the original frame structure is numerically calculated. The numerical calculation is followed by structural modifications of the frame and numerical calculation of the modified structure. Assembly drawings of the original and modified structure are processed based on the original and modified equipment models.

Additional equipment - Brush saw
Burian, Martin ; Malášek, Jiří (referee) ; Zeizinger, Lukáš (advisor)
This work deals with design of a circular saw as an attachment for skid steer loader. Attachment is used for felling and cutting woody plants. The introduction briefly describes machines that use these types of attachments and also describes some specific attachments from selected manufacturers. The following part of the work is design of own solution including the choice of components. The last part of the work deals with control and basic strength calculations of selected components. According to own design, 3D model of whole attachment is created and drawing documentation is made from this model.

Additional equipment - forest rope winch
Kovařík, Radim ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This work is focused on the design of a single-drum forest rope winch, which serves as an additional device for a universal wheeled tractor. The theoretical part of the work is focused on a general overview of the forestry techniques. The practical part deals with the calculation of basic functional parameters and strengths. Based on the calculated values, the actual design of the forest winch is created. Part of the design is the creation of a 3D model. Drawings of winch device, subassemblies of frame and drum are based on the created model.

Vibratory roller and plate for skid steer loaders
Rádsetoulal, Milan ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor’s thesis is focused on compaction machines like vibratory rollers and vibratory plates as auxiliary devices for skid steer loaders. This thesis is focused on a comparison of current devices in terms of technology and size. The designed solution of auxiliary vibratory plate focuses on solving main problems. There are also created coefficients that allow easy and fast comparison of each auxiliary devices. There are only a few companies that focus on creating this sort of devices. Auxiliary vibratory plates are often just slightly modified auxiliary devices for excavators, with slightly modified mount system. Vibratory rollers and plates cause high wear of skid steer loader and for this reason they are not widely spread. There will probably not be any future development in these kinds of devices due the fact, that there are better solutions for soil compaction.

Design of high mobility multipurpose vehicle.
Strnad, Martin ; Křenek, Ladislav (referee) ; Karásek, David (advisor)
The diploma work is focused on a complex design of a high mobility multipurpose vehicle. We live in a world full of dramatic changes and it brings many situations, which for a special equipment is needed. That should be right this vehicle. Thanks to its unique character, especially total variability and driving abilities, it is possible to solve various quests in all kinds of weather, terrain or environmental conditions. It is specially aimed on an projects economy and on an future development upgrade possibility.

The cleaning equipment for skid steer loader
Černý, Roman ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor’s thesis contains structural design and strength calculation of clearing equipment for skid steer loader. This device is used for cleaning of the public and parking area, sidewalks, roads and industrial buildings. According selected loaders are designed dimensions individual parts of machine with an emphasis on the initial terms of reference. The thesis includes drawing of design documentation of cleaning equipment.
