Crane Hook Block - Lifting Capacity 20 tons
Štefanec, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
Task of this bachelor’s thesis is to propose a crane hook block with lifting capacity of 20 tons. Hook block is part of the mechanism of class M4 according to technical standard ISO 4301-1. It briefly describes what hook block is and summarizes the design solutions of individual structural units. In next part of the thesis there is a design and calculation of the most important parts of the hook block due to function. The content is also a choice of purchased components. Thesis appendices consist of drawing of the whole assembly, lists of items and drawing of crossmember.

Topology optimization of crane hook
Rákoczy, Filip ; Malášek, Jiří (referee) ; Zeizinger, Lukáš (advisor)
Bachelor thesis deals with topology optimization methods for solid machine parts design. The theoretical part analyses general solution principles of optimization problems and lists particular use cases on real problems. The practical part describes a detailed case study of a crane hook and compares the results with standardized profiles according to ČSN. Finally, the designed hook profiles are evaluated and tested independently in two software’s using the finite element method.

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.

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.
