Examining sixty-eight bulk material handling machine failures over a forty-four year period this study investigates trends, the impact of standards and mitigating wind failures.
Over many mechanical inspections conducted by Aspec Engineering, it has been found that well over half, and likely as much as three quarters, of all rail clamps have not been functioning correctly. Sites have been inspected where the entire fleet of rail clamps is not working properly.
Aspec Engineering (ASPEC) was engaged to provide engineering support to a client that was upgrading part of their wharf-based rail infrastructure. By leveraging an automated CAD process, the project engineering was completed on time with no errors.
Mobile cranes are widely used in the engineering industry for the construction and assembly of heavy machinery, infrastructure and other large payloads. ASPEC has developed modelling and calculation tools to easily assess the suitability of cranes early in the design process.
Inspection of industrial structures utilises a condition rating system to track the degradation level of steel and concrete over time, using a 1 to 5 scale rating (pristine to unserviceable). The system allows for a consistent rating from any inspecting engineers. The paper gives background on the condition rating from the inspection system developed by ASPEC’s engineers.
This article describes design considerations for offshore marine bulk loading terminals. A form of construction using prefabricated steel jackets like those used in the offshore industry for drilling platforms is looked at in detail including design and construction requirements for application to large offshore dry bulk materials handling berths.
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.
Innovative strategies were required when presented with a variety of challenges for this large scale building foundation design. These include future proofing the foundation design for changes in design loading, as well as implementing efficient constructability solutions due to the challenging site environment.
