Despite the high technical level of hoisting equipment purchased abroad, a catastrophic failure of the slewing bearings of these cranes occurs after 3-5 years of service instead of the regulated 15 years. The most characteristic are: wear of 6-pol

Introduction. Deformations in bolted joints of elements in theoretical studies were taken into account by introducing linear deformation modules of elements instead of elasticity modules. The necessity to take into account the deformability of the in
