In the next part a proper rope hoist with appropriate engineering characteristics is selected. Then the design of the main girder follows. Its proportions are designated from the strength calculation, which are proved by check calculation. Another aim of this thesis is a project of the construction of the girder with a crossbeam, which is realized by fitted bolts. Their size is also calculated and controlled. Finally the carrying capacity of travelling wheel and control of the engine overloading is calculated
