Snow blower as an accessory for a small loader
Diviš, Přemysl ; Hloušek, David (referee) ; Škopán, Miroslav (advisor)
This bachelor's thesis provides the construction solution and a proposal of a snowblower as additional equipment to a skid steer loader. The project contains research on the construction of these devices, a description of the individual parts of the snowblower, and a functional calculation of the basic parameters needed for the selection of hydraulic motors. Furthermore, a strength check of important parts is performed, especially on the auger. As a part of the thesis, there is also drawing documentation of the snowblower and the welding auger.

Wood-splitting machines - security aspect
Láznička, David ; Zeizinger, Lukáš (referee) ; Malášek, Jiří (advisor)
The main goals of this bachelor thesis include development and critical research of splitting machines. The main focus is on manufacturers and types of log splitters, where their technical parameters, suitability for use and safety features protecting users are assessed. At the end of the work are the safety requirements set by the standard ČSN EN 609-1. Part of the work is also a 3D model of the splitting machine.

Conception of horizontal wood splitting device
Mikl, Marek ; Hloušek, David (referee) ; Pokorný, Přemysl (advisor)
The aim of the bachelor thesis is a brief research of wood splitting machines and splitting tools, then it was the task to create own design of the horizontal wood splitting machine with the use of splitting grid according to the given parameters. The thesis is divided into four chapters. In the first chapter, the research of splitting machines was solved, in the second chapter the machine design wich was made itself, in the third chapter the strength analysis of important machine parts and in the last part the control functional calculations were made.

Wood-splitting machine
Henzl, Lukáš ; Malach, František (referee) ; Malášek, Jiří (advisor)
The thesis describes the design of the wood-splitting machine including stress and check calculations and design of the hydraulic circuit. For structural design, it is necessary to choose the maximum dimensions of wooden logs, which have length 1,1 m and diameter 0,5 m and over. The machine structure is vertical. Another task of the thesis is a technical report of similar machines and the justification of the design concepts of splitting machine. In the thesis, there is elaborated an experiment on different types of wood splitters, stress analysis calculated by using finite element method and there is also drawn up technical parameters of wood.

Bending roll machine for Hardox
Budík, Tomáš ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
This work describes the design of a dedicated three-rolls hydraulic bending for Hardox 500 without the possibility of bending sheet metal for the manufacture of pipes. The work will analyze the problem of proposed three-rolls bending, bending technology and creating of the pre-bending, the design of the adjusting hydraulic servo-cylinder, planetary gearboxes with hydraulic motors to drive the bottom rollers, a partial draft of the hydraulic circuit and the complete frame structure of bending machine with its covers.

Hooclift NKH 8A340
Doleček, Ladislav ; Ospalík, Zdeněk (referee) ; Kašpárek, Jaroslav (advisor)
This master thesis analyses hook loader NKH 8A340. For calculation of load states was used the dynamic simulation in program MSC.ADAMS. This results were used like a input data to solve the construction with finished element method. After evaluation of results were made design changes of hook loader. Part of this thesis contains drawings of modified parts of hook loader.
