SCHMIDT, M.J. and VAN RENSBURG, B.W.J.. Avoiding structural failures on mobile bulk materials handling equipment. J. S. Afr. Inst. Min. Metall. [online]. 2015, vol.115, n.3, pp. 179-184. ISSN 2411-9717.
Bulk materials handling systems are extensively used in the mining and minerals industry, where a fairly high incidence of structural failure is experienced, notwithstanding design compliance with appropriate standards. A number of case studies are explored to demonstrate how insufficient controls or protection systems have contributed to structural failures on mobile bulk handling equipment. The importance of design integration across engineering disciplines is highlighted. The revision of ISO 5049-1 (1994) is proposed to provide specific rules and guidelines pertaining to machine protection systems. It is further recommended that the structural design engineer of the original equipment manufacturer (OEM) fulfils a more prominent role during the final acceptance and handover of mobile bulk handling equipment, with specific reference to protection systems.
