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.
Wind loading plays a role in structural design, influencing safety and performance. This article explores key changes from the 2011 version, highlighting how these updates enhance modern wind loading calculations.
PIANC has approved the development of WG261 guidelines, updating the original WG184 document. Chaired by Richard Morgan, with Grace Go as secretary, this update will enhance guidelines for dry bulk marine terminals, reflecting the latest industry advancements and sustainability goals.
ASPEC Director Richard Morgan presented updates on the AS 4324.1 revision at the ASEC Conference, highlighting major safety and resilience changes for materials handling structures. These revisions, due for release in 2025, set new standards for withstanding extreme weather and load demands.
Maintenance on large machines often involves the use of jacks, props or scaffolding which should be assessed under an ultimate limit state wind speed. A method for calculating reduced wind speeds for temporary works is presented that considers the short duration of the work and the accuracy of short-term weather predictions.
