Cable reel
Bunda, Petr ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The work deals with construction of electrical cable reel with lifting capacity 800 kg, height of lift 20 m and lift speed 10 m/min. In the work is solved design of cable, cable drum and its placing in frame, strenght calculations of the drum and its shafts, check calculations of bearings and keys, choice of suitable drive and its connection to the drum and fastening the whole to the base. Between parts of the work belong component drawings, parts list and assembly dravings with the main measurements and assembly diagram.

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.

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.

Trailer frame VARIANT 200 for transport cabel spools
Blažek, Jaroslav ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis is an analysis of the construction of a cable trailer VARIANT 200. For the calculation of load states was used a multi body system in program MSC.ADAMS. The results from these calculations were used as lifting conditions for strength control with finite element method (FEM). All acquired results were analysed and according to them changes were made to the frame construction. Part of this thesis contains drawings documenting the above mentioned changes.

Crab lifting gear 28 000 kg
Nečas, Jindřich ; Kubín, Martin (referee) ; Škopán, Miroslav (advisor)
Some lift devices are machine devices, with their support we can transfer some weights, hanging or fixted on supporting members, vertical or horizontal movement on designated place in restricted space. Some lift devices are classified after operating principle, travel distance and basic construction of the tree groups. This thesis solve proposal basic parameters lift, proposal cable mean, cable drum, guide and balancing block, including strenght calculation of cable drum and centric cog. Integral part of is also draft propulsion machinery, selection gear-box with brake and draft bearing for deposition centric cog of cable drum.
