Particular features of the load-bearing elements of rigging lifting systems

The problems of deformability of a large-capacity metal support beam are considered. The results of experimental studies and numerical analysis of beam deformability are presented. These studies take into account the specific interaction of stresses arising from the impact of loads on the product at operation, and residual welding stresses. Recommendations on stabilization of form deflections of metal construction of beams are given. (paper)
