Main goal of this thesis is to design an overhead traveling crane for lifting heavy vehicles with the mass up to 70 t inside an industrial hall where it is predicted that rails are leaning on load-bearing structure of the hall. Required lifting height is 12 m and demanded bridge span is 15 m. Vehicle has 4 lifting points with width span ranging from 3 to 5 m and length span ranging from 6 to 10 m. Crane operates in heavy duty conditions and inside industrial hall, thus the wind load can be neglected. In the first part of the thesis, a short analysis of the existing structural solutions of high load overhead cranes has been carried out with the purpose of choosing the optimal structural solution for given project parameters. In the second part of the thesis, a detailed calculation of the load lifting element for the chosen conceptual solution has been carried out, as well as the analytical calculation of bridge and trolley load-bearing structure according to cited literature. In addition, the selection of corresponding load lifting, as well the bridge and trolley drive units has been made. Finally, a CAD model and required technical documentation were made.
