From initial procurement to replacement or de-commissioning, Aspec Engineering provides a high standard of engineering services across the life cycle of bulk materials handling machines. The latest Machine Capability Statement is now available for download.
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.
Rotating steel shafts are typically one of the most critical mechanical components on mobile equipment. This article talks about some general principles of good shaft design and issues to be aware of.
Control systems on mobile equipment have advanced greatly in recent years and large SCADA datasets are available to analyse the machine performance. ASPEC has been processing and translating the SCADA data into engineering information, which is then used to carry out machine health checks to validate machine performance as part of asset management reviews.
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.
Materials handling machines are complex structures which often rely on load limiting devices to prevent damage. Fatigue damage is a consideration for machines of this type.
