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.

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.

Travelling crab
Odehnal, Jiří ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This Bachelor’s thesis deals with the design of a crane crab lifting gear with a load capacity of 10, 000 kg. Based on the entered parameters, the rope, rope drum, balancing pulley, and the block pulley’s main body parts, such as guide pulley, piston pins, side rails and crosspiece, are calculated. The thesis also includes a strength check of the rope drum and the individual parts of the block pulley, the draft of the lifting gear’s drive as well as the drawings of the block pulley set and selected parts.

Stroke mechanism of bridge crane 16 t
Kolegar, Vojtěch ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with design of hoist mechanism of bridge crane with maximum load capacity 16 000 kg. First part consists of critical survey of existing designs made by several companies with subsequent choice of suitable conception. Main part consists of calculation of fundamental parameters of hoist mechanism that are important for definition and selection of further parts of mechanism like steel rope, pulleys and pulley block with hook. Other selected and checked parts of hoist mechanism are rope drum, electromotor, gearbox and brake. Last part of this bachelor thesis consists of selection of bearing, bearing housing, spring of output gearbox shaft, pin and welds. The output of this bachelor thesis are technical drawings of hoist mechanism and weldment of rope drum.
