Calculation of vehicle elements load is a mandatory operation in the engineering of transport. The paper presents the calculation schemes of the static loading of the lever supports of the mobile hopper of bulk materials and determines internal force factors. The numerical values of equivalent stresses distributed on the lever of the mobile hopper of bulk materials are determined. The visualization of the results of calculating the stresses performed by the classical cross-section method and the finite element method is given. The results of both calculations show that the dangerous zone in the cross section of the lever is the neighbourhood of the hydraulic cylinder attachment. The analysis by the loading method shows the risk of breakage in the place of attachment of the hydraulic cylinder bracket from the side of the support wheel. To eliminate the revealed shortage there are proposals and recommendations given by the authors.
