Design of General Service Crane, used for manipulation on the deck of the vessel
Dlužanský, Tomáš ; Horák, Michal (referee) ; Pokorný, Přemysl (advisor)
This master's thesis makes a brief comparison of design variants of cranes for general use on the deck of a vessel. Further, this thesis deals with a design of a crane with a telescopic jib and a single knuckle. An important part of the crane’s design is its kinematic solution, which was modified in the design phase. The last step of a simplified analytical calculation of the jib for design steel construction is given. This preliminary calculation is the starting point for a FEM model and for the following FEM analysis. A stress control is made according to the Lloyd's Register of Shipping agency’s standard for lifting appliances in marine environment and also according to the recommendations of Huisman company. A part of the proposed solution is a selection of main components of the crane. The master’s thesis contains a summary of some operational and other information which characterize possibilities of the crane’s use. This thesis also includes source materials for drawing documentation.

Model ranges analysis of forest harvesters
Dlužanský, Tomáš ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
In the bachelor’s thesis is made the basic division of harvesters according to types of chassis, technology process of trees and sizes of harvesters. The next point of thesis is about construction of harvesters and about mechanical parts, especially harvester heads. In the next part division of some operational and technical arguments of Czech machines and foreign machines is made. There was critical classification of machines in groups, on the basis of these arguments. Critique was oriented mainly on wheel harvesters. This group was chosen because of its biggest representation in Czech Republic. Some structural specialities of harvesters and progress of harvester‘s technique were presented.
