Martinek, Jan ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
Windlass is a lifting device widely used in the building industry for lifting or laying building material or other material. This thesis consists of two parts. The theoretical part focuses on existing solutions of different windlass types and contains also a general overview of windlass producers. This part is also concerned with strength and functional calculations of the device and designs individual components of the device. The other part of this thesis is the construction part which is focused on drawings of the overal equipment assembly, contains the list of components and selected production drawings.

Design of electric tackle
Bádr, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
Purposes work was create technical documentation to an electrically driven tackle with actuated by hand undercarriage. Was booked up fundamental parameters like bearing, stroke and hoisting speed. First was effected calculation of load on pinion necks and an idle pulley. Subsequently was effected calculation for right election of a rope, an idle pulley, a rope drum and bearings for the rope drum. Up this calculation followed calculation for a right election of an electric motor and a shaft clutch. The documentation was complemented with pictures and tablets, that are seted near single decisive knots of the tackle. To the documentation was creationed how a suggested arrangement drawing so single subassemblies drawings.

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.

Možnosti zajištění korun stromů vázáním ocelovými lany s podkladnicemi
Mikulenka, Karel
Theme of the work is: "The posibility of ensuring the treetops by binding steel ropes with baseplates". This work deals with static binding on trees focusing on binding, using the steel ropes with baseplates. All components used to static binging are described in detail. Main object is to develop methodologies for installing this binding and their applications to trees with subsequent evaluation. At the same time has been inspected and measurements on different types of static bindings. Several trees were installed drilled binding which was removed after one year and was evaulated the influence of this binding on trees.
