For analysis of the influence of the braking gantry crane process with skewness on metalconstruction is presented in the process of braking crane in contact of wheelflanges with rail. The main conditions of the influencing on the chassis crane are determined. Calculating schemes of loading in linear and horizontal drive are presented. For determination of the changing loading, depending on braking moments, modeling process of the gantry crane КК-12,5-32 was fulfilled. The most powerful knots of the metalconstructions are the places of the mountings of support with girdercrane. Unstability of braking moments in which the power in metalconstruction doesn’t go beyond admitted limits for linear drive is 39,8%, for horizontal is – 37,1%.
