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.
ASPEC Engineering and Rendel’s Hay Point Shiploader and Berth Replacement project demonstrates advanced retrofitting techniques to extend the life of marine infrastructure by 50 years.
Strain gauging is an indispensable part of the engineering toolbox, serving as a means for understanding the structural performance of mining machines. From failure analysis to the optimisation of operational parameters, strain gauging aids engineers to ensure the safety, reliability and efficiency of critical mining infrastructure and machinery.
ASPEC was engaged to carry out a combined Order-of-magnitude/Pre-feasibility study for the replacement of a twin cell car dumper. Options considered in the study included combinations of partial and full cell refurbishment, replacement with like-for-like and replacement with upgraded cell designs. The study identified the best option to carry forward.
