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.

Bridge crane one-girder
Malár, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis is focused on the construction design of one-girder bridge crane for the LUVE – PLAST company. Construction design of the crane was developed in cooperation with the K-TECHNIK company, which carried out the production and installation of the crane bridge and the crane runway. The basic required parameters of the crane are: load capacity 8 000 kg, range 16 900 mm, minimum lift 4 650 mm. The crane, which construction is proposed in this thesis will be used for the exchange of forms of injection molding machines. The forms weight is about 7 000 kg. The aim of this work was to create a technical report with an analysis of construction choices solution with important technical and strength calculations. Calculations were made according to the Czech state standards and the literature dealing with the construction of bridge cranes. Further, the strength check of selected parts was made.

Design of electric tackle
Bádr, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
Purposes work was create technical documentation to an electrically driven tackle with actuated by hand undercarriage. Was booked up fundamental parameters like bearing, stroke and hoisting speed. First was effected calculation of load on pinion necks and an idle pulley. Subsequently was effected calculation for right election of a rope, an idle pulley, a rope drum and bearings for the rope drum. Up this calculation followed calculation for a right election of an electric motor and a shaft clutch. The documentation was complemented with pictures and tablets, that are seted near single decisive knots of the tackle. To the documentation was creationed how a suggested arrangement drawing so single subassemblies drawings.

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.

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.

Stroke mechanism of bridge crane
Wiesenberg, Adam ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor thesis is to develop a design of the lifting mechanism of a workshop bridge crane for a load capacity of 32,000 kg. The introductory part of the work is focused on a brief introduction to the issue, then there is a critical search of similar existing design solutions with related chapters dealing with the evaluation of concepts and selection of their own solutions and then follows the chapter Classification of crane and hoist. The second part of the work deals with the design and calculation of the main parameters of the lifting mechanism, including the choice of steel rope, rope hoists and calculation of the size of the rope drum. In other parts, the design and inspection of the rope drum, the selection of individual components of the lifting mechanism, such as the electric motor, gearbox, brake and clutches. The conclusion of the thesis contains the selection and method of bearing inspection, the design of the drum pin and the procedure of inspection of the tight spring joint. An integral part of the work is also the drawing documentation of the overall assembly of the lifting mechanism and the welding subassembly of the rope drum.
