Passenger lift 675 kg
Špunar, Martin ; Jedelský, Petr (referee) ; Pokorný, Přemysl (advisor)
This master’s thesis deals with the design of the carrying frame of a lift cage with lift capacity of 675 kg. It’s main content is follow up strength analysis by Finite elements method (FEM). Thesis also contains the calculation of counterweight mass. Further is performed the calculation of the guide anchoring instituted for this steel structure and the strength analysis of the used guides according to norm ČSN EN 81-1. The thesis also includes the drawing of the carrying frame of the lift cage. Master’s thesis was carried out in co-operation with the LIFTMONT CZ company, Ltd.

Manipulator automati conveyor container for injection molding machine
Rychtářík, Jan ; Pavlík, Jan (referee) ; Bradáč, František (advisor)
The thesis is focused on proposal of automatic transport feeder that can be used for injection moulding machines. It is concerned with conveyor belt, gravitational roller line and lift. Proposal of construction of automatic transport feeder, calculation of drive for conveyor belt and driven line is contained in this thesis. There is calculation of driveshaft, proposal of spring and calculation of bearing lifetime. Angle of conveyor of gravimetric roller line and speed at the end are calculated. Calculation of proposal of drive for lift and proposal of drive roller line on the lift is here. This thesis contains senzor, operation and steering, safety protection of feeder. There are applicability of robotic workplace and economic calculation at the end of thesis.

Optimal location of transform rollers of lift cabin
Žák, Martin ; Chalupský, Petr (referee) ; Špička, Jiří (advisor)
The work is a project of a component that allows lift transform rollers skewing. Three possible ways of construction are introduced. Their advantages and disadvanatages are mentioned. The best option was selected and checked by FEM. Prestressed bolted connection was also worked out. In the conclusion of the paper there is a source code of the computer programme for maximum rollers skew calculation.
