Continual double-helicoidal mixer
Černý, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This work focuses on the process of mixing particulate materials and the design of the screw mixer for this activity. The theoretical part describes the mixing and properties of particulate matter. Subsequently, individual devices serving for different types of mixing are analyzed. The practical part contains calculations of the main dimensions and the required power consumption. The choice of suitable drive, bearings and gear is followed. Finally, the analysis of the blade shaft load and the strength analysis of the mixer blade using Autodesk Inventor are performed. Part of this work is enclosed drawing documentation of equipment assembly and selected partial components.

Design of a pipeline chain conveyor
Machala, Petr ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master thesis deals with the construction design of two different pipeline drag chain conveyors for transport of wheat and sewage sludge. The first part describes the operation principle and the main parts of this conveyor. The examples of designs from several manufacturers follow. Next part is devoted to determining the resistance to movement in individual sections of the transport route. Thesis continues with design proposals of both variants of conveyors, including suitable technological and strength calculations. The outputs of this work are also assembly drawings of these two conveyors.

Bridge crane one-girder
Chroust, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
The focus of this thesis is the construction of a single girder overhead crane. The goal is to render a crane construction according to preset parameters. The parameters include a lifting power of 8,000 kg, a 10,000 mm reach, a 2,400 mm wheelbase and a stroke of 8,000 mm. The thesis includes brief theoretical research focused on overhead cranes, their various types and description of their main components. Brief description of chosen parameters for the construction itself follows. The description of chosen parameters includes calculations of strain acting during operation, technical and stability parameters, essential for the construction. All calculations were made with regard to valid Czech technical standards and specialized literature which focuses on the construction of cranes and their parts. Finally, the thesis is extended by the required technical drawings.

Bridge crane one-girder
Malár, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis is focused on the construction design of one-girder bridge crane for the LUVE – PLAST company. Construction design of the crane was developed in cooperation with the K-TECHNIK company, which carried out the production and installation of the crane bridge and the crane runway. The basic required parameters of the crane are: load capacity 8 000 kg, range 16 900 mm, minimum lift 4 650 mm. The crane, which construction is proposed in this thesis will be used for the exchange of forms of injection molding machines. The forms weight is about 7 000 kg. The aim of this work was to create a technical report with an analysis of construction choices solution with important technical and strength calculations. Calculations were made according to the Czech state standards and the literature dealing with the construction of bridge cranes. Further, the strength check of selected parts was made.
