Travelling Crab
Mikulec, Roman ; Řezníček, Milan (referee) ; Malášek, Jiří (advisor)
This work deals with the calculation and suggestion of the main parts of the travelling crab for lifting capacity of 45 000 kg. It consists primarily of determining the ropes, pulleys and cable drum and assigning of appropriate engine, brakes, gearbox and clutch. The work also contains strength calculation and suggested dimensions of main parts of sheave block, like the pin hook block, crossbeam, hook nut and rope pulleys, which are delivered with drawing documentation along with drawing of sheave block and piece list.

Travelling Crab
Šíbl, Michal ; Šťastný, Antonín (referee) ; Malášek, Jiří (advisor)
This thesis deals with proposal hoisting device of travelling crab with lifting capacity of 70 000 kg. The main objective is design of bearing elements of cable system – steel rope, pulleys and cable drum. The integral part of the thesis constitutes strength calculation of sheave block and design propulsion of hoisting device - motor, gearbox and brake. Drawing documentation shows sheave block, including piece list and drawings pulley, crossbeam, nut of crane hook and journal of pulleys.

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.

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.

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.

Crane Stroke Mechanism 25 t
Strommer, Bohumír ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The purpose of this bachelor thesis is the proposal of stroke mechanism of travelling crab with lifting capacity 25,000 kg. The proposal consists in calculations of the main dimensions of individual parts of the stroke mechanism, as the pulleys diameters, overall dimensions of the rope drum, rope diameter, then the choice of gearbox, brake, coupling and electric motor. There is a strength calculation of the rope drum and the bearing life calculation. Thesis includes assembly drawing of travelling crab and drawing of rope drum weldment.
