Travelling Crab
Hrnko, Lukáš ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The thesis deals with the structural design of the lifting device for the travelling crab with 50,000 kg capacity and lift if the intended use of the crane is in heavy traffic. The thesis includes a proposal for a block-and-tackle which contains suggestion for a suitable diameter and type rope, the strength design of rope drum, the strength design of individual parts of blocks, the choice of a suitable electric motor, the gearbox and finally, the brakes. Strength calculation of the tackle block was the basis for elaboration of drawing documentation for set of tackle block and its selected parts.

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.

Crab lifting gear 28 000 kg
Nečas, Jindřich ; Kubín, Martin (referee) ; Škopán, Miroslav (advisor)
Some lift devices are machine devices, with their support we can transfer some weights, hanging or fixted on supporting members, vertical or horizontal movement on designated place in restricted space. Some lift devices are classified after operating principle, travel distance and basic construction of the tree groups. This thesis solve proposal basic parameters lift, proposal cable mean, cable drum, guide and balancing block, including strenght calculation of cable drum and centric cog. Integral part of is also draft propulsion machinery, selection gear-box with brake and draft bearing for deposition centric cog of cable drum.
