Abstract:
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.
