Simulation of the trencher device prototype
Polák, Václav ; Sommer, Matěj (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis were a simulation and an analysis of the construction of a prototype of additional trencher equipment. At first an analysation of a prototype and a calculation of load states was made. A simulation was made in a multi body system in program MSC Adams View. According to load states was made a stress analysis in program MSC Apex Jaguar. All acquired results were analysed and according to them changes were made to the frame construction. Part of this thesis contains drawings documenting.

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.

Exploitation skid steer loaders possibility.
Blažek, Jaroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The thesis deals with posibilities of uses for skid steer loaders. It considers this problem from the viewpoint of the finding of optimal machine. For these purposes the thesis contains well-aranged tables of 101 types of loaders, which are by 15 leading companies manufactured. On the basis of these tables are the categories created. In every category is on the basis of determining criteria choosen the most and the least optimal skid steer loader.

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.

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.

The engine unit of a skid steer loader
Kročil, Petr ; Zeizinger, Lukáš (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with building skid steer loaders and problems of designing its engine unit. In the first section of this thesis there is a description of construction solution for loader and parameters comparison research of fifteen machines within same power category given by thesis requirements. The second section of thesis copes with design calculation of engine power unit, resulting from comparison of required power for individual working states which represents a sum of all power requirements of the machine for given working state. In the third section, the engine unit, which corresponds to the parameters design from the second section, is chosen from manufacture catalogues.

Koncept údržby kolových nakladačů
JŮZA, Jan
The Bachelor thesis deals with the issue of wheel loaders and their service. Wheel loaders are grouped according to their characteristics. There is a basic overview of the loaders' add-on devices and a description of their work activities. The final part is devoted to the maintenance of a particular loader. In this section, the loader is presented, described and gives specific servicing tasks. A financial evaluation is given for the selected servicing operations.
