The safety factor should be between 1.5 and 3 for the crane girder design as recommended. The value of this stress is calculated by dividing yield strength by the safety factor is assumed that is 1.98. The value of the allowable stress the beam material (σ all ) amounts to 120 MN/m 2. The loadings have been considered in the elastic range and therefore the elastic constants were assumed, corresponding to the steel S235: Young's modulus (E) equal to 2.1e+5 MN/m 2, the Poisson's ratio (ν) of 0.28 and the yield strength (R e ) of 235 MN/m 2. The assumed pressure value of 13 513 513.514 N/m 2 multiplied by the contact surface of the trolley wheels with the beam corresponds to the load force of 50 kN. The movement of the crane trolley performed by moving the pressure which acts on the contact surface of the trolley wheels with the beam, to consecutive positions along the crane beam, ignoring inertia effects. The pressure value is the result of the total weight of the loaded crane trolley that can travel along the upper flange of the gantry crane beam. The considered beam of the gantry crane with cross section of the: a) I-beam, b) box beam, c) thick-wall box beam The structure is loaded by the pressure perpendicular to the upper flange of the beam and directed downward, i.e.
