Topology optimization of crane hook
Kabelka, Jaroslav ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
This final bachelor's thesis discusses the importance of topological optimization in solutions with regard to crane hooks. The thesis deals covers the theoretical part and the computational practical part of a specific crane hook. In the theoretical part, in addition to optimization methods, models, boundary conditions and the softwares, various types of hooks, their construction and properties are examined. In the computational part, the thesis then deals with a specific case of topological optimization of a crane hook, followed by validation and comparison of the obtained results.

Travelling Crab
Mikulec, Roman ; Řezníček, Milan (referee) ; Malášek, Jiří (advisor)
This work deals with the calculation and suggestion of the main parts of the travelling crab for lifting capacity of 45 000 kg. It consists primarily of determining the ropes, pulleys and cable drum and assigning of appropriate engine, brakes, gearbox and clutch. The work also contains strength calculation and suggested dimensions of main parts of sheave block, like the pin hook block, crossbeam, hook nut and rope pulleys, which are delivered with drawing documentation along with drawing of sheave block and piece list.

Design of crane hook production
Horák, Tomáš ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of the production of a crane hook made of C45 steel. After evaluating suitable technologies, die forging on a mechanical press was chosen. Based on the analysis of technological technology, the shape of the part was modified and all necessary additions and limit deviations of forging dimensions were determined. The semi-finished product with a diameter of 65 mm and a length of 380 mm will be formed on a cross wedge rolling mill, bent on a separate press and subsequently forged. The crank forging press LZK 3150 B from the company ŠMERAL Brno a. S., With a nominal forming force of 31.5 MN, was chosen from the calculated forming force. The construction of the dies is based on the ČSN 22 8306 standard and they are made of 19,552 steel with subsequent heat treatment.

The changeable strut devices for cranes in hall
Dvořáček, Jan ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
This thesis was created for Bosch Rexroth in order to simplify the lifting work in the manufacturing hall. There was made the construction project of changeable strut devices for lifting loads. The project is comprised of two parts. The first deals with the analytical calculation and the second part consists of a numerical calculation using the finite element method.

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.
