Stroke mechanism of bridge crane
Wiesenberg, Adam ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor thesis is to develop a design of the lifting mechanism of a workshop bridge crane for a load capacity of 32,000 kg. The introductory part of the work is focused on a brief introduction to the issue, then there is a critical search of similar existing design solutions with related chapters dealing with the evaluation of concepts and selection of their own solutions and then follows the chapter Classification of crane and hoist. The second part of the work deals with the design and calculation of the main parameters of the lifting mechanism, including the choice of steel rope, rope hoists and calculation of the size of the rope drum. In other parts, the design and inspection of the rope drum, the selection of individual components of the lifting mechanism, such as the electric motor, gearbox, brake and clutches. The conclusion of the thesis contains the selection and method of bearing inspection, the design of the drum pin and the procedure of inspection of the tight spring joint. An integral part of the work is also the drawing documentation of the overall assembly of the lifting mechanism and the welding subassembly of the rope drum.

Travel mechanism of a 60 t bridge crane with a rocker arm arrangement
Ptáčník, Michal ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The bachelor's thesis deals with the calculation and the design of a concrete running mechanism of the bridge crane, which moves inside the hall. The running mechanism is stored in a pendulum arrangement, and the lifting capacity of the crane is 60 tons. The research part deals with similar design solutions. Subsequently, the engine, gearbox and brakes are designed. Further, the calculation of the individual components of the running mechanism is carried out. The output of the whole work is the drawing documentation.

Protiblokovací systémy brzdové soustavy a systémy jízdní stability vozidel
Fischer, Michael
Master’s thesis deals with anti-lock braking system and systems for riding stabilization of vehicles. Theoretical part of this paper describes active forces on a vehicle with emphasis on the braking process. The next part describes a design of a braking system with anti-lock braking system, and anti-slip regulation, and design of electronic stabilization program. Every subchapter dealing with system also contains a description of its function. Practical part of this thesis deals with measurement of braking with active and no active ABS done with Volkswagen Golf IV. This measurement was done on chassis dynamometer. Measured results describe the process of braking force and braking acceleration or deceleration. In the end of the thesis is comparison of results of braking with ABS for different pressure inside of tires.

Stroke mechanism of bridge crane
Jirásek, Jiří ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the lifting mechanism of the crane cat, for a bridge storage crane with a load capacity of 8,000 kg. The thesis contains a critical research of similar existing solutions and the selection of the appropriate concept. The design includes calculations of the basic parameters of the stroke, and based on them selects appropriate rope, pulleys, and design of the rope drum. Furthermore, there are calculated and selected suitable components of the stroke mechanism such as electric motor, clutch, brake and gearbox. The last part deals with the design of the bearing, the drum pin and the calculation of the shaft key. The output of the work is the technical drawing of the whole assembly of the mechanism and the welding subassembly of the rope drum.

Stroke mechanism of bridge crane
Ujčík, Miroslav ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This thesis deals with the design of a stroke mechanism of the bridge crane with capacity of load 12 000 kg, which will have served as a plant crane with regular use. The first part of this thesis is devoted to the critical research of similar existing solutions, on the bases of which a suitable order of the arrangement is chosen. The other part of the thesis is devoted to the calculation of the main dimensions of the stroke, on the basis of which the individual components are selected, this are hoist elements of the rope system, such as roller, rope and rope drum, in which the fatigue calculation is performed. Another part of the thesis tackles design and parts calculation of the lifting mechanism, such as electric motor, clutch, brake and gearbox. The final part of the thesis is devoted to the calculation and control of the drum flail, bearing and tension calculation of the parallel key. Constituent part of this thesis is also drawings´ documentation, which enclosed drawing of the lifting mechanism assembly and the welding subassembly as well.

Soustava těles s pasivním účinkem s brzdou
Genco, Ondřej ; Hájek, Petr (referee) ; Fuis, Vladimír (advisor)
This thesis deals with the solution of the body system using NNTP static theory model. The introductory part defines the basic magnitudes and concepts, describes the constraints and the types of passive effects. In the practical part, the influence of passive effects on different moving states in the particular system of the towed trolley is determined. Furthermore, two variants of mechanical friction brakes are designed and compared. The numerical values of unknown parameters are determined by solving the system of linear equations in Matlab.

The bridge crane's travel mechanism
Žid, Miroslav ; Nezbeda, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of this master thesis is to design replacing the central drive of the overhead crane with dislocated drives. It´s a tong crane with the lifting capacity of 63 tons, located inside the hall. In the thesis is processed functional calculation of two types of drives, the associated types of brakes and the coupling element. Next there is a strength control of a new mechanism seat and a selected components. This whole leads to the output, which is the drawing documentation.
