Grapple for logs
Bubník, Tomáš ; Mergl, Václav (referee) ; Kašpárek, Jaroslav (advisor)
The presented work deals with the design of a collet grapple for handling wooden logs and lumber. The work contains a research part of current versions of grabs from both Czech and international companies. It discusses the methods of performing the most used variants of the kinematics of the collet movement, the description of individual technical components and their functions. In the construction part, the work deals with the choice of suitable materials and electrodes, the design of the dimensional parameters of the grapple, the design of a double-acting linear hydraulic motor, sliding and joint bearings and supporting shafts forming rotational connections, a tie rod loaded for buckling and tension, a hydraulic rotator and the design of suitable dimensional parameters of the claws of the collet. An unloading set consisting of a hydraulic arm and an unloading hoist is designed for the grab, for which a stability check is carried out. The result of the work is a functional collet grapple made of high-strength steel for handling wooden logs of smaller weight.

Handling equipment for forestry
Martinec, Patrik ; Pokorný, Přemysl (referee) ; Hloušek, David (advisor)
This bachelor thesis is focused on a research treatise on a forest fleet. The beginning of the work outlines the historical development of machines in the woodworking industry, it also deals with harvesters and their individual division according to specifications. The work also focuses on important parts of the harvester such as the hydraulic crane and harvester head. In the same spirit of comparison and division, export tractors are developed in the work. The chapter of the last work summarizes wheel loaders and their use in the woodworking industry. At the end of the thesis, the individual goals and outputs of the bachelor's thesis are evaluated.

Handling equipment for a storage of the barrels
Matyáš, David ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
The Bachelor´s thesis deals with the design of handling equipment for barrel warehouse as additional device for forklifts. Forklift moves on the flat floor of the warehouse. All functions of the mechanism are powered by hydrostatic oil pressure. In the thesis, some design proposals are made, after their evaluation is chosen final variation which includes functional and strength calculations. The chosen concept includes a drawing documentation.
