DURABILITY OF CRANE METAL STRUCTURES

Abstract

The connection of the crane beams is performed by directly joining their elements, or using fillets. The change in the height of the beam is made in the form of an angular transition with a broken profile of a belt or a degree with a fillet. In all cases, significant stress concentrators arise in these nodes. Moreover, unlike machine parts in thin-walled structures, stress concentration occurs not only at the "concave" nodes, but also at the "convex" ones.
