Construction of boom of loader Dapper
Gregor, Jiří ; Petráš, Jiří (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the analysis of the current kinematic mechanism of the DAPPER 5000 boom. The second part of the thesis deals with the new mechanism design. The new solution is also analysed kinematically and forcefully. The first part of the thesis is devoted to a description of the DAPPER 5000 and its parts. It is followed by a description of its boom, its analysis and comparison with the booms of competitive loaders. After a critical review of the various boom concepts, where their suitability for the DAPPER 5000 is assessed, a new mechanism for the DAPPER boom is designed. This is followed by a detailed analysis of this mechanism, a basic strength check and, in conclusion, the results of the analyses are summarized, and the meaningfulness of this structural change is evaluated.

High loading shovel for loader
Rajdl, Marek ; Papoušek, Libor (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis deals with design of the high loading shovel for the loader Komatsu WA380. The aim is to find constructional solutions of the high loading shovel for a minimal dumping height of 4 500 mm, for the bucket width of 3 000 mm and for the bucket volume of 5 m3. The thesis contains a brief description of the high loading shovel and description of basic constructional components. It also contains choices of basic constructional components, a calculation of the necessary force to tilt the bucket and a static analysis. Stress control of the bucket, the frame and the pegs forms the final part of the thesis. The thesis is accompanied by the necessary technical drawings.
