Undercarriage of the tracked excavators and dozers
Hampl, Pavel ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with the analysis of the tracked undercarriage of excavators and dozers. The first part defines basic information about the tracked excavators and dozers. The second part is devoted to the analysis of the current concept of the tracked undercarriage of excavators and dozers. The third part compares the used drive systems and mechanisms with regard to efficiency and economy.

Dozer of non-homogeneous materials
Sekava, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
The aim of the master’s thesis is to design a hydraulically controlled dozer for nonhomogeneous materials. The proposed dozer of non-homogeneous materials is attached to a telehandler. The thesis is divided into a theoretical and practical part. In the theoretical part contains a summary of similar machinery, a description of a telehandler and a summary of possible non-homogeneous materials. The practical part deals with the structural design of the proposed dozer. The design includes selection and justification of the chosen concept, important technical calculations, a scheme of the hydraulic circuit, strength check calculations, and drawing documentation.

Dozer of non-homogeneous materials
Henzl, Lukáš ; Hloska, Jiří (referee) ; Malášek, Jiří (advisor)
This thesis describes the design of the hydraulic dozer of inhomogeneous materials, especially for ploughing of manure from the stables of corridors, with the possibility of dozer changes in working widths as needed. This machine will be attached to the telescopic handler Manitou MLT 845 – 120 LSU. Another part of the thesis is the technical report about similar machinery and the justification of designed concept of the pusher block. The thesis presents important technical calculations and an overview of possible inhomogeneous materials that could be ploughed by the plow blade. The thesis includes drawings of weldment of the centre of blade and drawing of the whole composition of plow blade.

The study of leveling systems for construction machines
Sedlařík, Ondřej ; Kašpárek, Jaroslav (referee) ; Urbánek, Michal (advisor)
This bachelor’s thesis deals in the first part with the research analysis of leveling systems. Leveling systems are divided according to the number of working levels and the type of working signal. Subsequently, individual types are described more in detail considering to function and use. The next part deals with an overview of manufacturers of leveling systems and their products on the european market. The table comparsion was made of main parametres of leveling systems based on the previous overview. Finally, the leveling systems were valuated based on table values.

Dependency analysis of efficiency of dozers on technology work and technical parameters.
TROJAN, Aleš
The paper deals with the explanation of technological works of dozers and the division of operational institutions of a dozer. The aim of this work is to propose principles for the calculation of the actual performance of dozers in relation to operations. This work can be a useful document that can be used by construction companies for accurate calculations of dozer efficiency and thereby achieve improvement and optimization in relation to other operations.
