The article calculates the analysis of the stress-strain state of the traverse, taking into account additional loads acting in full-scale operating conditions. The presented calculation methodology is based on determining the permissible stresses and modeling the structure using the finite element method. A design scheme, a solid-deformed model have been developed, and a finite element method has been calculated in the CAD / CAE system. To determine the operating values in the steel structure of the lower service, we will construct a model in natural values with observance of the given characteristics and geometrical dimensions. The stress-strain state of the traverse elements is quite complex, since both compressive stresses and tensile stresses arise in one element in different planes, which are interchanged during the operation of the lifting structure. The above calculation and analysis of the strength of the metal structure of the lifting structure showed that this approach is suitable for the development on its basis of expert systems for assessing the lifespan of lifting structures, both at the stage of design and at the stage of operation
