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
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.

Calculation of crane ropes
Fiala, Lukáš ; Basista, Filip (referee) ; Pokorný, Přemysl (advisor)
This master thesis deals with calculation of steel wire ropes for cranes. Concretely is acted about calculation of wire ropes overhead crane manufactured by KRÁLOVOPOLSKÁ a.s. designed for load capacities up to 25 000 kg, which is situated at hall of steelworks. Further, the calculation of wire ropes different overhead crane was made to compare the results. The solution includes calculation made using valid standards ČSN 27 0100, DIN 15020-1, FEM 1.001 and ČSN EN 13001-3-2. Finally, the procedures are evaluated and compared with each other.

Analysis of traverse of bridge magnet crane 15t
Bartušek, Filip ; Jelínek, Petr (referee) ; Pokorný, Přemysl (advisor)
The diploma thesis deals with some parts of bridge magnet crane with 15 tons of nominal lifting capacity. This crane is designed for operation in the steel mill for handling billets using magnets suspended on the traverse. This work is focused on design of hoisting and traverse mechanism of crane trolley, selection of individual components on the basis of relevant standards and calculations. Next part of this thesis is investigation magnet traverse in terms of its strength according to standard ČSN EN 13001.

Travelling crab
Pokorný, Emil ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This thesis deals with calculation and proposal hoisting mechanism of travelling crab with lifting capacity of 25 000 kg. In this thesis are proposed elements of rope system, which include rope, pulleys and rope drum. Part of the thesis is also the strength calculation of the sheave block and proposal of individual components of the lifting mechanism drive such as engine, gearbox and brake. The output of this thesis is a drawing documentation including drawing of the sheave block assembly and drawings of selected details.
