Crane hook block - lifting capacity 25 tons
Šanca, Kristián ; Trčka, Tomáš (referee) ; Malášek, Jiří (advisor)
The crane block is the lower part of the hoist. It is designed to fulfill a load capacity of 25,000 kg, while being safe and as light as possible. The work describes the principle of the hoist. A design solution is chosen in which two ropes are wound on a drum. The calculation of the hoist is in the calculation part, the components of the hoist are further described and calculated, using basic strength calculations. Attached is a drawing of the assembly and important details.

Jib crane for handling metal plates
Dobšíček, Tomáš ; Prachař, Vlastimil (referee) ; Škopán, Miroslav (advisor)
This diploma thesis deals with the construction design of revolving column crane which is used for manipulation with metal plates for metal shears and bending bench. The aim is to set main proportions and basic parameters for the designed steel construction via design calculation. Then the thesis deals with checking of strength analysis done by programme I-DEAS NX 11. Suggestion of disposal placement of the crane, choice of hoist, travelling system, auxiliary device and drawing documentation are also parts of the design.

Stroke mechanism of bridge crane 16 t
Kolegar, Vojtěch ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with design of hoist mechanism of bridge crane with maximum load capacity 16 000 kg. First part consists of critical survey of existing designs made by several companies with subsequent choice of suitable conception. Main part consists of calculation of fundamental parameters of hoist mechanism that are important for definition and selection of further parts of mechanism like steel rope, pulleys and pulley block with hook. Other selected and checked parts of hoist mechanism are rope drum, electromotor, gearbox and brake. Last part of this bachelor thesis consists of selection of bearing, bearing housing, spring of output gearbox shaft, pin and welds. The output of this bachelor thesis are technical drawings of hoist mechanism and weldment of rope drum.
