Travelling Crab
Šponar, Pavel ; Kašpárek, Jaroslav (referee) ; Malášek, Jiří (advisor)
Bachelor thesis deals with a project of the travelling mechanism of the travelling crab (electric motor and gear-box) and check calculation for starting. The aim of this work is to design a travelling wheel with save, therefore it is necessary to design the suitable normalized components. The solidity calculations of the travelling wheel, the bearing and shaft ( static and dynamin straining).

Travelling Crab
Komůrka, Martin ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This thesis deals about engineering design and calculation hoisting mechanism of travelling crab for capacity 20 000kg and lift height 36m. For this task are made necessary calculations concerning hoist, crane cable, cable pulleys, cable drum. Further, they are drawn strength calculations pin of pulleys, sidewalls, crossbeam and crane hook. Then is also set a drive part of hoisting mechanism consisting of calculation and choice motor, gearbox and brake. The result of this thesis is drawing documentation of pulley block and manufacturing drawings of individual parts.

Traveling Carb 36 tons
Kantor, Roman ; Nezbeda, Jiří (referee) ; Mynář, Břetislav (advisor)
Diploma thesis is concerned with the solution of main measurements of the carriage travel which will use for loading and expounding iron scrap. Manipulation with iron scrap will be by electromagnet. Part of calculation includes the computation of travelling apparatus, travelling gearbox and power of electric motor. It also sort out the calculation of the main measurements of lift apparatus, power lift of eletric motor, calculation gearbox and strop. Subseguently deal with calculation of fixity of carriage travel´s framework

Crane trolley 32 t
Knapec, Tomáš ; Nezbeda, Jiří (referee) ; Škopán, Miroslav (advisor)
This master’s thesis is the design development of crane trolley, which is used to manipulate with scrap material. The target of this thesis is to develop a technical report including calculations of running and lifting gear, strength calculation of frame of trolley and drawings containing assembly of crane trolley and assemblies of running and lifting gear. Desired parameters of this trolley are maximum load capacity 32 000 kg, lifting height of 11 m, working lifting speed up to 10 m/min and working running speed up to 50 m/min.

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.

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.

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.

Travelling Crab
Bernard, Vladislav ; Špička, Jiří (referee) ; Malášek, Jiří (advisor)
This work dissert about proposal and calculation hoisting device travelling crab, intended for tonnage 50 000 kg. For this tonnage there're performed pertinent strenght calculations, concerning journal of pullies, side plate, crossbeam and crane hook. Part of work is proposal desirable electric motor, gear - box, brakes, jaw clutch and bearings. In work are also descriptions of hoisting apparatus and descriptions of construction parts of sheave block. Defined are also main dimensions ancillary components for desired hoisting. Work is finished with complete drawing documentation of sheave block travelling crab.
