Bridge crane
Plášil, František ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with the design of an overhead crane. In the first part, the research of the current situation and description of individual parts has been made. It is followed by the choice of a suitable concept design with respect to the specified parameters. The following part describes important technical calculations for the structure of the crane. Calculations are made according to valid Czech state standards. In the final part, the calculation of the structure using the finite element method analysis is performed and the financial balance of the project is proposed. Last but not least, an assembly drawing of the crane and selected detailed drawings are attached.

Calculation of crane ropes
Fiala, Lukáš ; Basista, Filip (referee) ; Pokorný, Přemysl (advisor)
This master thesis deals with calculation of steel wire ropes for cranes. Concretely is acted about calculation of wire ropes overhead crane manufactured by KRÁLOVOPOLSKÁ a.s. designed for load capacities up to 25 000 kg, which is situated at hall of steelworks. Further, the calculation of wire ropes different overhead crane was made to compare the results. The solution includes calculation made using valid standards ČSN 27 0100, DIN 15020-1, FEM 1.001 and ČSN EN 13001-3-2. Finally, the procedures are evaluated and compared with each other.

The design of the crane tracks in a production hall
Lobreis, Jan ; Pilgr, Milan (referee) ; Štrba, Michal (advisor)
This work focuses on the design and assessment of the steel crane runways for two separated craneswith the capacity of 20 t, respectively 50/12.5 t. The main girder of the crane runway is designed as a welded uniaxially symmetric I-section consist a lattice horizontal reinforcing beam. The individual crane tracks are located within the building two-aisle production hall (one in each boat) with dimensions of 75 x 48 m and height of 14.9 meters. The building is located in an industrial area Holešov and its supporting structure is designed from crosslinks consisting of solid-welded columns and truss. Spatial rigidity of the hall is provided by tension bracings. The structures are made of the steel S 235. For designing of a production hall (for the assessment) it is only software Scia Engineer (planar model) used. The design and evaluation of crane runways are compute by hand calculation.

Steel structure of an industrial building
Blaška, Jan ; Pilgr, Milan (referee) ; Sýkora, Karel (advisor)
The bachelor thesis is about designing the single-aisle industrial hall bearing structure. The width of the hall is 18 meters, the length is 63 meters and height of the holder of a crane track girder is 12,3 meters. There are two trolley cranes in the building. Their carry capacities are 20/5 t and 32/8 tons. The main bearing components are the transversal restrained columns and strut-frame stringers. The purlins are strut-frame. The structure is designed for the district of Blansko.

Crane Runway of Container Transshipment in Moravský Krumlov
Robotka, David ; Barnat, Jan (referee) ; Pilgr, Milan (advisor)
The aim of this paper is focuses on the design and to check of a supporting steel structure of an outdoor crane runway for an overhead crane for container manipulation. The structure is located in Moravský Krumlov. The crane with carrying capacity 50/12,5 t, hoisting class of appliance HC3 and claffication of fatigue actious s5 moves on a track. Total length of the runway is 50 m with span of the crane bridge 28,5 m of a total height 13 m above the terrain level. Crane runway beam of the main crane track consists of a welded single symmetric I profile, and is accompanied by trussed surge girder of crane runway beam. Spatial rigidity of the structure is provided by columns in a lateral direction, and by braking bracing in the longitudal direction. The columns are designed as a plate column, in the shape of double symmetric I profile. The load-carrying structures are made from a S355 steel grade, while the columns are made from a S235 steel grade.

The Three Aisled Storage Building
Malý, Jan ; Sýkora, Karel (referee) ; Buchta, Stanislav (advisor)
The subject of this bachelor´s thesis is the design and assessment of steel structure three-aisled storage building. The width of the side aisles is 12 meters and the width of the main aisles is 24 meters. The length of storage building is 60 meters. The height of the building is 14.65 meters. In the main aisles traversed, by two bridge cranes, each with a capacity of 5 tons. The supporting structure consists of main truss, the distance is 6 meters. Storage building is designed for the area of Zlín.

Stroke mechanism of bridge crane
Ujčík, Miroslav ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This thesis deals with the design of a stroke mechanism of the bridge crane with capacity of load 12 000 kg, which will have served as a plant crane with regular use. The first part of this thesis is devoted to the critical research of similar existing solutions, on the bases of which a suitable order of the arrangement is chosen. The other part of the thesis is devoted to the calculation of the main dimensions of the stroke, on the basis of which the individual components are selected, this are hoist elements of the rope system, such as roller, rope and rope drum, in which the fatigue calculation is performed. Another part of the thesis tackles design and parts calculation of the lifting mechanism, such as electric motor, clutch, brake and gearbox. The final part of the thesis is devoted to the calculation and control of the drum flail, bearing and tension calculation of the parallel key. Constituent part of this thesis is also drawings´ documentation, which enclosed drawing of the lifting mechanism assembly and the welding subassembly as well.

Hall for Engineering Production
Slezák, Jaroslav ; Pilgr, Milan (referee) ; Karmazínová, Marcela (advisor)
The aim of the bachelor thesis was to design and assess a steel two-nave hall for engineering production in Rajhrad. The hall has a rectangular plan with a width of 32 m (20 m and 12 m) and a length of 63 m. The total height of the main nave is 13.5 m. One bridge crane with a capacity of 5 t and a span of 19 m runs in the hall. The building is be covered with a gable roof with a pitch of 5 %. The modular spacing of the main trusses is 6 m. The superstructure consists of truss girders, full-wall columns, bracings and full-wall purlins. The RFEM program was used to determine the internal forces on the individual structural elements.

Auxiliary crab for overhead foundry crane
Adam, Petr ; Nezbeda, Jiří (referee) ; Kašpárek, Jaroslav (advisor)
This master thesis deals with issue design of crab trolley. Concretely is acted about auxiliary crab trolley with required capacity 65 000 kg. This crab is on overhead crane, which is situated at hall of foundry. In particular chapters is processed design of lifting mechanism and travelling mechanism, which is amended to strength control of frame. This whole leads to output solutions, which is drawing documentation.

Crane Stroke Mechanism
Vydra, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of crane stroke mechanism with lifting capacity of 12 500 kg. At the beginning is research of different design solutions, their comparison and finally selection of the most suitable conception. Before calculation part of each unit is short theoretical part, which brings basic information about issue, whose result in choice of product from catalogues. On the grounds of calculations, firstly hoist parts are chosen, such as rope, pulleys, rope drum and main units of crane mechanism – electric motor, gear box and brake with coupling. Final part deals with strength calculations of rope drum and drum shaft and design of his bearing housing. The practical part of the work are assembly drawings of crane stroke mechanism and rope drum weldment.
