Production technology of horizontal cable tray for low-voltage switchgear ABB
Attasek, Ondřej ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
In bechelor thesis is the main task of manufacturing the component that is made of galvanized steel sheet of DX51D+Z/+Z material with thickness of 1,5 mm. The component is produced using technology of cutting and multiple bending. The main aim is to suggest technological process of cable tray for installation of low voltage switchgear for the ABB Ltd. company. Yearly production expectation is 2 650 units. Part of the work is also required technological calculations for notching plan, cutting force and force for bending. In thesis is also elaborated technical-economic evaluation with the drawing documentation.

Risk analysis of crane operation
Attasek, Ondřej ; Mukhametzianova, Leisan (referee) ; Kotek, Luboš (advisor)
The topic of this master's thesis is focused on the area of safety in lifting technology. Specifically, to prevent mistakes during bridge crane operations and to increase reliability of the human factor. The thesis summarizes the most important legislative regulations for crane operators, including the requirements for operation. Furthermore, there are analysis of bridge crane accidents including data about number of occupational accidents. Other part of the thesis deals with analysis HTA, human HAZOP, BOMECH and FMEA. Conclusions are set based on these analyzes and preventive measures are suggested.
