Differential tackle
Valach, Petr ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor’s thesis deals with the calculation and construction proposal of self-locking differential tackle with lifting capacity of 600 kg and lift of 3.7 m. After a short division of tackles according to various criteria and their description is followed by a more detailed description of the chosen construction of the differential tackle. The thesis includes the calculation of the sprockets according to the relevant norm, the choice of the chain, bearing selection, assessment limits and safety self-locking and important strength calculations taking into account the manual manipulation. There is the drawing documentation according to the topic of the bachelor’s thesis.

Design of lifting gear of bridge crane 50 tonne
Koutný, Pavel ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
The submitted bachelor thesis deals with the design of a lifting gear for a bridge crane on 50 tonnes. The first part includes a design and a calculation of a rope, rope pulleys, design of a block and a cable reel. In the second part there is chosen an electromotor, a transmission, a brake, a clutch and bearings. Relevant strength calculations of a cable reel and a cable reel bolt are made for the capacity of 50 tonnes. The output of this bachelor thesis is a drawing documentation of a cable reel and a manufacturing drawing of reel components.

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.

Stroke mechanism of crane trolley
Galas, Radovan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
Bachelor's thesis deals with design of stroke mechanism of crane trolley loads for the weights which do not exceed 5 000 kg. This thesis divided into written and practical sections. Written part deals with the calculation of the principal dimensions of lifting and stress control of cable reel. In this work there are also given reasons for choosing certain key parts of the lifting mechanism, such as: electric motor, gearbox, etc. Prior to the calculations in each chapter there is usually located a short introduction of the topic. The practical part contains a drawing of the complete lifting mechanism, cable reel assembly and two production drawings.
