The paper presents the analysis of the gantry crane loading when driving along the crane track, using a 3D model, for which the analysis of the gantry crane frame loading was performed. The gantry crane is designed to remove dirt that is in front of the turbine under the water surface. For the gantry crane which moves along a track, the directional and vertical unevennesses were determined by experiment and are given in graphic and numerical form in (mm), relating to A track and B track with a total track length of 450 (m). Based on the knowledge of the unevenness of the rail track, the four random functional dependencies defining the irregularities of the individual rails as input variables were used for the kinematic excitation of the individual wheels of the gantry crane. The stress analysis was performed for a travel speed of 30 (m/min) and a lift of 10 (t) under the given loading. The results of the stress analysis are presented in graphic form.
