Crane crab of bridge rack crane of load 30 t
Kolegar, Vojtěch ; Bartušek, Filip (referee) ; Škopán, Miroslav (advisor)
This diploma thesis deals with mechanical design of crane trolley of overhead bridge rack crane with maximum capacity of 30 000 kg used for manipulation with steel coils. Diploma thesis is divided to several chapters. The beginning is dedicated to brief survey and definition of overhead cranes. First main chapter deals with draft and functional calculation of fundamental parameters of hoist mechanism and continues by selection and verification of individual parts of hoist mechanism. Second main chapter deals with design and description of construction of upper rotational frame of crane trolley, guiding pillar, and handling mechanism. Description of design of all construction is followed by determination of several loads of each construction part including the load factors for the correct dimensioning of their construction. The last chapter is static strength analysis of mentioned parts of bridge rack crane. A description of the procedure for creating a computational model, scenarios of load conditions is made and the whole chapter ends with evaluation of the results of the static strength analysis. The output of thesis are calculation report of hoist mechanism and his components, technical drawings of hoist mechanism, weldment of handling mechanism and upper rotational frame with guiding pillar and handling mechanism.

Traveling and slewing mechanism of the crane trolley of a 30-ton overhead stacking crane
Zicho, Jan ; Bartušek, Filip (referee) ; Škopán, Miroslav (advisor)
This diploma thesis deals with the design of some mechanisms of the overhead stacking crane working with steel coils in the steelworks. The main point of this work is to create technical documentation consisting of the design of the traveling and slewing mechanism of the 30-ton crane trolley and the traveling mechanism of the crane cabin. The technical documentation also includes the stress calculation of the main trolley frame using FEM and drawing documentation of the main parts of a crane trolley. This master´s thesis was created in cooperation with KPC a.s.

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.
