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
Jirásek, Jiří ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the lifting mechanism of the crane cat, for a bridge storage crane with a load capacity of 8,000 kg. The thesis contains a critical research of similar existing solutions and the selection of the appropriate concept. The design includes calculations of the basic parameters of the stroke, and based on them selects appropriate rope, pulleys, and design of the rope drum. Furthermore, there are calculated and selected suitable components of the stroke mechanism such as electric motor, clutch, brake and gearbox. The last part deals with the design of the bearing, the drum pin and the calculation of the shaft key. The output of the work is the technical drawing of the whole assembly of the mechanism and the welding subassembly of the rope drum.
