Travelling and lifting mechanism
Kukla, Antonín ; Malach, František (referee) ; Malášek, Jiří (advisor)
The main objective of the thesis is to design and construct a taxiway and a lifting device for moving a BELL helicopter with slides. Handling equipment is used for transporting helicopters between the airfield and hangars. The thesis is divided into several parts. The first part includes the design of taxiway and lifting equipment. Other parts contain strength calculation of selected parts and design documentation, which includes assembly drawings and important groups drawings.

Project of service lift
Drápela, Josef ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deal with project of service lift. The service lift is drive by special mechanism using thrust chain. The chain is led from chain accumulator over sprocket gear to vertical guiding groove. Lift car is connected to the end of chain. There are designed and described the most important constructional unit of service lift in this thesis. But the most attention is pay to drive, including break system and chain accumulator. The drive is consist of electric motor, clutch, break, planetary gearbox and sprocket gear.

Mechanical rake screen
Žemlička, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with construction concept of mechanical rake screen and consists of several main sections. The first section of the diploma thesis covers an overview of the current supply of mechanically scraping rack. In the second section, basic parameters and calculations are solved for the mechanical rack construction concept. In the third one however, analysis of the construction is realized with SolidWorks modeller and the functions of particular parts of the rack is explained. The last section of the diploma thesis focuses on stress control using classic calculation methods and Finite Element Methods (FEM) using a program called I-DEAS.

Transport truck for castings
Krbeček, Petr ; Malach, František (referee) ; Malášek, Jiří (advisor)
The diploma thesis deals with the construction design of rail mounted transfer cars. The first of the designed cars is equipped with the electrical drive and the second is non-driven and must be towed or pushed. This thesis contains description of main components of the transfer cars and their implementation. The next section deals with original construction design of the transfer cars. The thesis includes functional calculation of travel wheels, the design and check of the travel unit and the strength calculation of the connecting pin. Conclusion of the thesis deals with the strength analysis of the transfer car frame using the finite element method. The required technical drawings are attached to the thesis.

Mechanical cleaner-machine
Čejda, Robert ; Malach, František (referee) ; Malášek, Jiří (advisor)
The aim of my diploma thesis is to design a construction of a mechanical fine rack cleaner machine including an appropriate design of gear mechanism and its attachment to the frame. The cleaner machine is located in the inflow system of a turbine in front of the object of small hydro power station. The design of the construction of the cleaner machine will be based on a drawing documentation and a report with needed analytic and FEM calculations.

Bridge crane two-girder
Vajmar, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis describes the design of two-girder overhead crane. At the beginning of the work are designed sectional characteristics of the girder and the crossbeam. Furthermore, they are calculated loads applied during crane operation. Following the determination of the static load and fatigue strength. All calculations are solved with respect to relevant standards relating to overhead cranes. The work also includes analysis of purchased components, which are geared motors, bumpers and drive (no drive) wheels.
