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.

Wheel-mounted gantry crane
Hlobil, Jaroslav ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
The aim of the present bachelor's thesis is a structural proposed design of a cantilevered frame, and also the structural proposed design of a wheel-mounted gantry crane, wheel-mounted gantry crane which is earmarked for a manipulation with containers on the containers' terminal surface. Additionally, the thesis deals with the proposed design of the prime load-bearing crane's components and with its strength analysis. Eventually, it also shows the mentioned proposed design with essential operational calculations, and the most important part devoted to the drawings' documentation.

Travelling Crab
Komůrka, Martin ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This thesis deals about engineering design and calculation hoisting mechanism of travelling crab for capacity 20 000kg and lift height 36m. For this task are made necessary calculations concerning hoist, crane cable, cable pulleys, cable drum. Further, they are drawn strength calculations pin of pulleys, sidewalls, crossbeam and crane hook. Then is also set a drive part of hoisting mechanism consisting of calculation and choice motor, gearbox and brake. The result of this thesis is drawing documentation of pulley block and manufacturing drawings of individual parts.

Traveling Carb 36 tons
Kantor, Roman ; Nezbeda, Jiří (referee) ; Mynář, Břetislav (advisor)
Diploma thesis is concerned with the solution of main measurements of the carriage travel which will use for loading and expounding iron scrap. Manipulation with iron scrap will be by electromagnet. Part of calculation includes the computation of travelling apparatus, travelling gearbox and power of electric motor. It also sort out the calculation of the main measurements of lift apparatus, power lift of eletric motor, calculation gearbox and strop. Subseguently deal with calculation of fixity of carriage travel´s framework

Crab of container gantry crane
Doležel, Radek ; Malášek, Jiří (referee) ; Pokorný, Přemysl (advisor)
This bachelor's thesis deals with design of crane trolleys, with a load capacity of 80 t and a lift height of 22 m. This crane trolley is constructed for a gantry crane used in a container transshipment yard. The gantry crane ensures the relocation and transfer of containers to means of transport. In this work, one specific type of a crane cat with two lifting drums and four travel wheels is calculated. The work is divided into three main parts. The first is a brief search of lifting devices. The second part is computational. The last part is focused on assembly drawings and welding of the main frame.
