Mini dumper for transporting bulk material
 Sedláček, Tomáš ; Škopán, Miroslav (referee) ; Zeizinger, Lukáš (advisor)
The bachelor's thesis deals with the conceptual design of a minidumper. These machines are primarily used for transporting bulk material in small-scale earthworks. The introductory research describes selected similar devices. The research section serves as a basis for selecting a suitable conceptual solution. In the thesis, the solution of a tracked minidumper with a hydrostatic drive system and a hydraulic tipping of the dump body is selected. Part of the conceptual solution design is the design of the hydraulic circuit. Furthermore, the construction of the tracked chassis and other selected components is specified. The calculation section focuses on machine's drive system and the tipping of the dump body. This section covers the selection of the power unit, hydraulic pump, hydraulic motors and the linear hydraulic actuator. The end of the thesis is dedicated to the strength analysis of the machine's frame. The frame is subjected to strength analyses using the finite element method. Throughout the strength analyses, the frame is modified to enhance its load-bearing capacity. Drawing documentation for the final version of the frame is created. The thesis also includes drawing documentation of the minidumper assembly.
