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.

Derrick crane
Kuhejda, Lubomír ; Šťastný, Antonín (referee) ; Pokorný, Přemysl (advisor)
This bachelor’s thesis is aimed on construction design of derrick crane for capacity of 1 000 kg, lining length of 4 000 mm and lift height of 4 800 mm. The purpose is to make design of main carrier and function elements including selection of suitable hoist by given requirements. Strength calculation of selected parts was made according to current applicable standards ČSN 27 0103. In the annex of this thesis are also assembly and manufacturing drawings.

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.

Overhead electric hoist
Hruška, Miroslav ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The theme of this bachelor’s thesis is overhead electric hoist, designed for lifting capacity 1,500 kg. It produced a technical report containing the calculation and design of electrical drives and lifting travel hoists including control of these drives. There are also carried out appropriate travel gear and travel, clutches, brakes and bearings and strength calculation of ropes and rope drum. Part of this work is to build the entire proposed drawing devices.

Derrick crane
Berner, Tomáš ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This Bachelor’s thesis will deal with the construction design of derrick crane. Aimed at design main structural parts. It is discussing about their suggest by means of projecting calculation and checking by the control calculation. Crane enables boundless extent of revolving, downrighting load with maximum weight 1000 kg is 4000mm. Thesis will deal with the selecting right tackle too.

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.

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.
