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.

Development of algorithm and pertinent program mogule for statical and dynamical analysis of cables on pulleys
Štekbauer, Hynek ; Hradil, Petr (referee) ; Němec, Ivan (advisor)
The goal of this master thesis is to develop an algorithm for solving cables on pulleys, which would be more efficient and accurate than existing algorithm used in software RFEM. This algorithm was integrated to the program for static and dynamic analysis of structures, in the form of particular program module. This work also contains examples of using this algorithm. The comparison of expected results with outcomes from the program is presented. The suitability for common practise is examined based on this comparison. The examples showed that the new algorithm for solving of cables on pulleys is more powerful and more accurate than existing solutions and most likely does not has equivalent competition.

Stroke mechanism of crane trolley
Malár, Martin ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the stroke mechanism of the crane trolley, maximum weight of loads is 16 000 kg. The work is divided into two parts: a written part and a practical part. In the written part of this work there are the main dimensions of lift and control cable drum strength solved. The calculation is subject to quantities that are given by assignment. Choice of the electric motor, gearbox and follow-up control of the stroke speed according to customer requirements is discussed further. The second part includes production drawings, in which are included the total set of the stroke mechanism and other assemblies and production drawings.
