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.

Stroke mechanism of crane trolley
Galas, Radovan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
Bachelor's thesis deals with design of stroke mechanism of crane trolley loads for the weights which do not exceed 5 000 kg. This thesis divided into written and practical sections. Written part deals with the calculation of the principal dimensions of lifting and stress control of cable reel. In this work there are also given reasons for choosing certain key parts of the lifting mechanism, such as: electric motor, gearbox, etc. Prior to the calculations in each chapter there is usually located a short introduction of the topic. The practical part contains a drawing of the complete lifting mechanism, cable reel assembly and two production drawings.

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.

Overhead electric hoist
Hruška, Miroslav ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The theme of this bachelor’s thesis is overhead electric hoist, designed for lifting capacity 1,500 kg. It produced a technical report containing the calculation and design of electrical drives and lifting travel hoists including control of these drives. There are also carried out appropriate travel gear and travel, clutches, brakes and bearings and strength calculation of ropes and rope drum. Part of this work is to build the entire proposed drawing devices.

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.
