Vydra, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of crane stroke mechanism with lifting capacity of 12 500 kg. At the beginning is research of different design solutions, their comparison and finally selection of the most suitable conception. Before calculation part of each unit is short theoretical part, which brings basic information about issue, whose result in choice of product from catalogues. On the grounds of calculations, firstly hoist parts are chosen, such as rope, pulleys, rope drum and main units of crane mechanism – electric motor, gear box and brake with coupling. Final part deals with strength calculations of rope drum and drum shaft and design of his bearing housing. The practical part of the work are assembly drawings of crane stroke mechanism and rope drum weldment.
