Stroke mechanism of bridge crane
Jirásek, Jiří ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the lifting mechanism of the crane cat, for a bridge storage crane with a load capacity of 8,000 kg. The thesis contains a critical research of similar existing solutions and the selection of the appropriate concept. The design includes calculations of the basic parameters of the stroke, and based on them selects appropriate rope, pulleys, and design of the rope drum. Furthermore, there are calculated and selected suitable components of the stroke mechanism such as electric motor, clutch, brake and gearbox. The last part deals with the design of the bearing, the drum pin and the calculation of the shaft key. The output of the work is the technical drawing of the whole assembly of the mechanism and the welding subassembly of the rope drum.

Model ranges analysis of threshing machine
Palík, Milan ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The scope of this bachelor work is to give the basic information and explain the functionality of particular harvester thresher mechanism and confront their synthesis and product mix from different producers. The agricultural engineering sale is large and that is why the first step of the usage will be the company literature and then professional magazines will be given. This work is mainly made through the use of visual documentation, which afford explanation of existing mechanics principle, their particular structural design and summary of producers. Then there will be mentioned their percent sales representation and the confrontation according to the efficiency classes. The attention will be first of all paid to the best in this field, for example to the companies, which are engaged in picking engineering production for cereals, as are for example companies Claas, Fendt. Case IH or New Holland.

Travelling and lifting mechanism
Havlas, Tomáš ; Kašpárek, Jaroslav (referee) ; Malášek, Jiří (advisor)
The bachelor thesis deals with the design of travelling and lifting mechanism. At the beginning of the thesis various types of handling device are described. We attend to the summary of these mechanisms in full details, especially these ones which are the accessible in practice. Main part of the thesis is focused on strength calculations and construction of the designed handling device. The process of calculations and compiled plan of our design are included.

Lifting roller table
Korytář, Jan ; Malášek, Jiří (referee) ; Kašpárek, Jaroslav (advisor)
This thesis deals with the current lifting devices and conceptual design of the lifting roller table, which serves as a knot on the transport line. The table is used to transport 1000 kg EUR pallets, with a 200 mm height change required. The thesis contains a brief analysis of the lifting structures, the design of the roller track, the design and strength calculations of the scissor mechanism. It also includes assembly drawings, frame subassemblies, and workshop drawings.

Three - side gate with hydraulic open mechanism
Krůza, Libor ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The bachelor project deals with design solutions of the mechanism hydraulically open side gate. The side gate is part of a three-sided dump trailer. The tilting body is used for transport of the powdery materials. The main task of the mechanism is to open the side gate without a driver’s manual work. The side gate is hydraulic open.

Grapple saw for wheel loader
Roguljić, Adam ; Kubín, Martin (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis was to design and construct a claw collector for a pre-selected wheel loader. The loader was chosen based on the basic parameters of the specified machine (engine power, the useable load of the machine, the hydraulic system pressure and weight of the machine). The collector is used for the unloading or loading of wood material, in this case, the raw wood in the form of logs harvested and stored on a freight truck or vice versa. The load capacity of the claw collector is specified at 4500 kg. For the drawing documentation I used the graphic programs based on the CAD platform. Specifically, the program that I have chosen was AutoCAD from the software company Autodesk. I performed a preliminary calculation of strength and stability control of the machine. In addition I also prepared the complete design documentation in the form of drawings which include the detailed shop drawings of individual parts of the machine.

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.
