- The article analyzes the safety aspects related to the construction and operation of a mobile crane. The load-bearing capacity of the boom sub-assembly rotation node was tested in a mobile crane. When identifying the load, the uneven compliance of the supporting components was taken into account. The considerations are illustrated with an example of a mobile crane slewing bearing with a lifting capacity of 50 tons. The basic problems of building the computational model are discussed and the results of the load bearing capacity of the slewing ring bearing for different positions of the load-bearing component of the tested machine are presented. An analysis of the load of the rolling elements in a slewing ring bearing was carried out and the reasons for changes in the load capacity in relation to the methods of calculating the load capacity, assuming non-deformability of the bearing rings, were indicated. It has been shown that deformations of the supporting frames are so large that they significantly change the distribution of forces transmitted by individual bearing rollers.
