Marandoo and Hope Downs 4 Crusher Upgrades
Agilitus was awarded the State Winner of the WA Steel Excellence Awards for the Hope Downs 4 Crusher in 2022.
The Primary Crusher at Marandoo was identified as having Class IV structural integrity risks, with vibration levels exceeding permitted standards by 100 times. To resolve this, Agilitus engineered a large concrete and steel isolation frame mounted on air springs beneath the existing floor.
Our team completed the feasibility study, detailed design, including shop detailing, construction support and commissioning support to resolve structural dynamics issues on this project.
Our team also provided access to the model in a virtual reality environment giving both Rio Tinto and construction contractor the ability to prepare for shutdown work in a fully immersive environment. This resulted in the contractor being able to better plan work and minimise the risk of issues during construction and commissioning.
As a result of the successful implementation at Marandoo, Rio Tinto engaged Agilitus to apply the same solution at the Hope Downs 4 (HD4) Primary Crusher. Both crushers are now operating efficiently, with vibration levels within the design specifications.
“What sets Agilitus apart is our integration of engineering insight with real-world site experience. Our team combines advanced analytics, such as vibration modelling and strain gauging with hands-on knowledge from operating environments. This means we don’t just deliver calculations; we deliver fit-for-purpose solutions that improve reliability, minimise downtime, and safeguard productivity.
We’re also highly adaptable: from rapid structural inspections on mine sites to long-term monitoring programs, we scale our services to meet client needs.”
