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.

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.
