Design of doublebeam of bridge crane 8 tonne
Bobčík, Martin ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with design of doublebeam of bridge crane (8 tonne). The purpose of this thesis is to design the main parameters of the crane bridge. First of all, I chose from the catalog wire rope hoist. I proposed preliminary dimensions of mainbeam and crossbeam. I made strength check of mainbeam and crossbeam. For attachment mainbeam and crossbeam I chose fitted bolts. I calculated required number of fitted bolts M12. From the standards I chose wheels. I checked the wheels to maximum contact pressure and service life. I chose bearings from catalog SKF. I checked the bearings to service life. I proposed dimension of shafts. From the rolling resistance and friction, I calculated the power output of the engine. At the last I proposed cable trolleys and control of the crane.

Design of doublebeam of bridge crane 50 tonne
Matěja, Josef ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
The Bachelor’s thesis deals with the design of two-girder crane bridge for the lifting capacity 50 tons. The process is split in eight parts. The first one contains a preliminary scheme of the whole design and proposal of main parameters. The second part contains calculation of preloading of the girder, specification of its main dimensions and calculation of maximum bending moment. The other parts include calculations and designing of individual main parts and accessories such as crane girder, cross girder, wheels, rails, gear and brake. The bachelor’s thesis has been elaborated using the relevant technical literature and standards that contain procedures and recommendations for calculation and designing of bridge cranes.
