Travelling Crab
Bernard, Vladislav ; Špička, Jiří (referee) ; Malášek, Jiří (advisor)
This work dissert about proposal and calculation hoisting device travelling crab, intended for tonnage 50 000 kg. For this tonnage there're performed pertinent strenght calculations, concerning journal of pullies, side plate, crossbeam and crane hook. Part of work is proposal desirable electric motor, gear - box, brakes, jaw clutch and bearings. In work are also descriptions of hoisting apparatus and descriptions of construction parts of sheave block. Defined are also main dimensions ancillary components for desired hoisting. Work is finished with complete drawing documentation of sheave block travelling crab.

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.

The effect of shoulder girdle stabilization exercises on muscle activity during direct impact in rugby players with subacromial impingement syndrome
Chytilová, Martina ; Šťastný, Petr (advisor) ; Satrapová, Lenka (referee)
Title: The effect of shoulder girdle stabilization exercises on muscle activity during direct impact in rugby players with sub-acromial impingement syndrome Objectives: Comparison of muscle activity during direct impact while performing the rugby tackle to tackle bag and to player using amplitude analysis of electromyographic signal (EMG) before and after intervention programme for players with subacromial impingement syndrome (SIS). Application of intervention programme consisting stabilization excercises for shoulder complex and activation of deep stabilization muscles of the spine. Methods: Theoretical part contains topics about shoulder girdle, rugby and rugby injuries, mainly subacromial impingement syndrome and electromyography. Mentioned issues are included into the thesis due to the research of current literature from international sources and studies. Practical part regards the aplication of three- months long intervention programme for eight rugby players at junior national level with diagnosis of SIS, when pre-testing a post-testing is realized by clinical tests and EMG measurement. Results: Intervention programme was sufficient for changes of EMG amplitude values expressed as percentage of maximal voluntary isometric contraction (MVIC) in some of rugby players with SIS only for some...

Title: The effect of shoulder girdle stabilization exercises on muscle activity during direct impact in rugby players with sub-acromial impingement syndrome Objectives: Comparison of muscle activity during direct impact while performing the rugby tackle to tackle bag and to player using electromyographic amplitude analysis before and after intervention programme for players with subacromial impingement syndrome (SIS). Application of intervention programme consisting stabilization excercises for shoulder complex and activation of deep stabilization muscles of the spine. Methods: Theoretical part contains topics about shoulder girdle, rugby and rugby injuries, mainly subacromial impingement syndrome.

Practical part regards the aplication of three-months long intervention programme for eight players at junior national level with diagnosis of SIS, when pre-testing a post-testing is realized by clinical tests and EMG measurement. Assessment of enter and control examination is realized with analysis of variance ANOVA. Results: Intervention programme was sufficient for changes in EMG amplitude for two muscle groups in rugby players with SIS. Hypothesis comparing the EMG measure...
