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.

Electric winch for drilling wells
Volec, Martin ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis undertakes design of two speed electric winch for the headgear specified for the drilling of the water wells through the use of core technology with the loading capacity up to 1000 kgs. Thesis consists of the theoretical as well as the operational part. Theoretical part is occupied with the possibilities of the problem solving, calculates the main winch parameters. In the study the reasons for choices of the main parts of mechanism e.g. electromotor, transmission, winch and others are given. Generally the brief introduction into the problem is inserted in each chapter prior to the calculations. Operational part involves the drawing of the overall configuration and the cable drum setup.

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.

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.

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.
