Stroke mechanism of bridge crane
Drábík, Michal ; Sedláček, Martin (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis is focused on the design stroke mechanism of bridge crane with load capacity of 10 000kg. The thesis contains a critical research of today-manufactured crane trolleys and a selection of a suitable conception. Part of the design are calculations of the lifting mechanism base parts, for example: rope diameter, pulleys diameters, complete dimensions of the rope drum, selection and the design of the electric motor, gearbox, brake, frequency inverter, gear and drum coupling. Last chapter is focused on the strength calculation of the rope drum, durability of the bearing, weld strength examination and radial load. Part of the thesis is the lifting mechanism assembly drawing documentations and the rope drum welding assembly.

Stroke mechanism of bridge crane
Wiesenberg, Adam ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor thesis is to develop a design of the lifting mechanism of a workshop bridge crane for a load capacity of 32,000 kg. The introductory part of the work is focused on a brief introduction to the issue, then there is a critical search of similar existing design solutions with related chapters dealing with the evaluation of concepts and selection of their own solutions and then follows the chapter Classification of crane and hoist. The second part of the work deals with the design and calculation of the main parameters of the lifting mechanism, including the choice of steel rope, rope hoists and calculation of the size of the rope drum. In other parts, the design and inspection of the rope drum, the selection of individual components of the lifting mechanism, such as the electric motor, gearbox, brake and clutches. The conclusion of the thesis contains the selection and method of bearing inspection, the design of the drum pin and the procedure of inspection of the tight spring joint. An integral part of the work is also the drawing documentation of the overall assembly of the lifting mechanism and the welding subassembly of the rope drum.
