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.

Production of a hollow pin by cold forming
Šanca, Kristián ; Řiháček, Jan (referee) ; Jopek, Miroslav (advisor)
The hollow pin with a length of 45 mm and a diameter of 28 mm made of 12 050 steel is produced by cold cold forming. It showed defect-translation and the goal was to eliminate it by optimization. 10 variants were proposed, of which No. 10 was without defects and the goal of the work was met. The forming process was simulated by Simufact Forming software. The semi-finished product is a block made of a round bar 18 x 35.68. The part is manufactured on a process tool for 4 operations by a combination of upsetting and extrusion. The machine used is the CBF-204L automatic machine. The required force is 3 042 kN. The price of 1 piece is CZK 19.59. 120,000 pieces are produced annually.
