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

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.

Travelling Crab
Hrnko, Lukáš ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The thesis deals with the structural design of the lifting device for the travelling crab with 50,000 kg capacity and lift if the intended use of the crane is in heavy traffic. The thesis includes a proposal for a block-and-tackle which contains suggestion for a suitable diameter and type rope, the strength design of rope drum, the strength design of individual parts of blocks, the choice of a suitable electric motor, the gearbox and finally, the brakes. Strength calculation of the tackle block was the basis for elaboration of drawing documentation for set of tackle block and its selected parts.

Crab lifting gear 28 000 kg
Nečas, Jindřich ; Kubín, Martin (referee) ; Škopán, Miroslav (advisor)
Some lift devices are machine devices, with their support we can transfer some weights, hanging or fixted on supporting members, vertical or horizontal movement on designated place in restricted space. Some lift devices are classified after operating principle, travel distance and basic construction of the tree groups. This thesis solve proposal basic parameters lift, proposal cable mean, cable drum, guide and balancing block, including strenght calculation of cable drum and centric cog. Integral part of is also draft propulsion machinery, selection gear-box with brake and draft bearing for deposition centric cog of cable drum.
