How innovative shiploader technology helped Queensland Alumina Limited reduce dust emissions while protecting ageing wharf infrastructure and improving environmental performance.
Earthquake-resilient infrastructure is critical in mining operations, particularly in seismically active regions. This article examines the impact of recent earthquakes on a mine in New South Wales’s Upper Hunter region. Following a magnitude 4.5 event in September 2024, ASPEC Engineering conducted structural assessments, finding no critical damage but identifying safety concerns in non-structural elements.
Aspec Engineering undertakes Plant Integrity Reviews (PIRs) for bulk materials handling machines to help owners and operators understand current condition, operational performance and remaining service life. This article outlines the key components of a PIR, including on-site inspections, Machine Book review, analysis of SCADA data and engineering assessments used to identify defects, assess compliance with…
ASPEC acted as independent auditor and technical advisor to TasRail for the Berth 5 Shiploader Replacement at the Port of Burnie, including verification of the shiploader, conveyor gallery and wharf strengthening works.
The release of AS 4324.1:2025 marks three decades of a landmark Australian Standard shaping bulk-materials handling machines in mines and ports.
Roy Hill’s proposed new Berth 3 (SP3) is set to boost iron ore exports with a smarter, more efficient design. Aspec Engineering and Rendel Ingerop were engaged to rework the original concept, introducing a “piggy-back” conveyor and prefabricated wharf jackets with modular deck units.
Wind loading significantly affects the design of conveyor galleries due to their elongated shape and exposure to aerodynamic effects. This article explores factors influencing drag coefficient variation and the impact of selected multipliers from AS/NZS 1170.2:2021 on wind load calculations.
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.
Understanding brakes and wheel rail friction is essential for keeping materials handling machines safe and reliable. This paper looks at the factors that impact friction, like contamination and torque, and offers practical insights for managing performance risks.
