Machine stability calculations are a critical step in determining the design quality and safety of a machine. This paper details the process in conducting a machine stability assessment and identifies the required and typical wheel loads for different types of bulk handling machines.
At many existing bulk material handling facilities, equipment such as stackers, reclaimers and ore car dumpers are nearing the end of their design lives. Owners are faced with the decision on whether to refurbish existing or procure replacement machines. ASPEC’s program called FULS (Fatigue Useful Life Simulation) helps determine when to carry out machine replacement or major refurbishment.
PIANC recently published WG184 Design Principles for Dry Bulk Marine Terminals in March 2019. PIANC formed WG184 as no current guidelines existed for the planning and design of specialist marine terminals for the import and export of bulk solids.
The International Standard ISO5049.1, for bulk materials handling machines such as stackers, reclaimers, ship loaders and ship unloaders, was used in Australia until 1995. Since then Australia has followed the AS4324.1 standard. There are significant differences between the two standards; this article will explain further.
This article provides a high level summary table of changes in the AS4324.1-2017 standard and likely implications for new and existing machines.
