Overhead travelling crane 125t
Peprník, Pavel ; Zimola, Lubomír (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with the assessment of drafted steel construction of overhead travelling crane by using finite element method. The crane’s lifting capacity is 125t/32t. It is going to be placed in hall of Slovácké strojírny, a. s. in Uherský Brod. Span of the crane is 25.8 meters, wheelbase is 6.7 meters and lifting height is 17 meters. My work contains analysis and assessment of crane construction with a load of fatigue according to ČSN 27 0103.

Static design of the crane runway - comparative calculation
Krompolc, František ; Melcher,, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The purpose of bachelor thesis is recalculation the crane runaway according to current Eurocodes (CSN EN 1991-3 a CSN EN 1993-6) comparing results with the recalculation according to previous standards (CSN 27 0103 and CSN27 0101). In the hall there is one trolley crane. Its capacities is 12,5 tons. The structure is designed for the area of city Koprivnice. The main beam 12,0 m in length is welded biaxial symmetric I profile. Heigth of the beam is 800 mm, width is 300 mm, thickness of the flange 30 mm and web thickness is 30 mm. Horizontal bracing beam is truss girder - one belt is the upper belt of the main crane beam and second one is made from the half of HEB 140 profile. On the horizontal truss girder there is revision footbridge. Diagonals 1803 mm in length are designed from L70x70x7 profile. Vertical beam length is 1000 mm and is made from L50x50x5 profile. Length of truss is 1500 mm. Free belt of horizontal truss is supported by angled bars , which are connected to upper belt of the main crane beam, creating a fulltruss system in oblique level.

To problems of effective and reliable design of crane girders
Kočařová, Jindřiška ; Juhás,, Pavol (referee) ; Rozlívka,, Lubomír (referee) ; Brodniansky,, Ján (referee) ; Melcher, Jindřich (advisor)
Recently the most often used crane runway beams designed from rolled HEA sections as multispan beams is the topic of this doctoral thesis. It deals with the study of real stress in the cross section focused on local stress analysis in the web of cross section due to eccentricities of wheal load and on the problems of stress analysis above the middle support of multi-span beams. First, the outline of crane supporting structures, currently used methods of implementation and available stress analysis methods are summarized. Than two parametrical studies of crane runway beam design depending on statical determination of the beam, crane span, crane wheelbase and chosen quality of structural steel are presented. Following part of thesis contains the stress analysis of crane runway two-span beam in its continuous part above the middle support on implemented crane supporting structure. Experiment of crane runway two-span beams actions above the middle support are described in the last part of the thesis. Closing part of thesis summarizes results.

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.

Over head travelling double beam crane
Jašíček, Petr ; Jírů, Miroslav (referee) ; Špička, Jiří (advisor)
In the thesis according to the award (the design and assessment of the basic elements of container crane, design and calculation drives of bridge and cats, including relevant drawings) developed completely. Assessment of the basic elements of container crane is carried out according to CSN 27 0103 Design of steel structures and cranes CSN 73 1401 Design of steel structures. It is designed and calculated drives as a bridge crane and drive cats. The thesis is processed into different units according to the award.

Bridge crane two-girder
Vajmar, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis describes the design of two-girder overhead crane. At the beginning of the work are designed sectional characteristics of the girder and the crossbeam. Furthermore, they are calculated loads applied during crane operation. Following the determination of the static load and fatigue strength. All calculations are solved with respect to relevant standards relating to overhead cranes. The work also includes analysis of purchased components, which are geared motors, bumpers and drive (no drive) wheels.

Traveling Crab 360 t
Sláma, Ondřej ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
The topic of this diploma thesis is the frame of the foundry crane with load capacity 360 t. The frame is analysed by strength inspection and fatigue strength inspection according to norm ČSN EN 13001. The analysis are made by using finite element method on shell model. The diploma thesis was made in cooperation with Královopolská a.s. company.

The bridge crane's travel mechanism
Žid, Miroslav ; Nezbeda, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of this master thesis is to design replacing the central drive of the overhead crane with dislocated drives. It´s a tong crane with the lifting capacity of 63 tons, located inside the hall. In the thesis is processed functional calculation of two types of drives, the associated types of brakes and the coupling element. Next there is a strength control of a new mechanism seat and a selected components. This whole leads to the output, which is the drawing documentation.
