Abstract This paper is the result of an intensive literature search and practical study of the problems experienced by a mining company with the frame cracking of their large-tonnage haulage trucks. It explains the advantages of particular HSLA steels for applications in the welded structures of such equipment. Examples of existing welds in truck frames are analyzed. Modern fatigue models and linear elastic fracture mechanics techniques are explained.
Keywords: Equipment, Materials, Mining equipment, Steel, HSLA steels, Trucks, Welding, Maintenance. Fatigue models, Fracture mechanics.
