Project Scope:

  • EDC was engaged by MRL to conduct a Machine Audit for the following Machines:
    • Mine Reclaimer
    • Mine Stacker
    • Port Bridge Reclaimer
    • Port Ship-loader
  • Develop a finite element model of the machine and utilise it to conduct a design audit to AS4324.1-2017.
  • Ongoing design support for the OEM DHHI.


  • An iterative design process meant high levels of collaboration required between client, supplier and auditor.
  • Unique machine type being designed, limited learnings applicable from previous audits.
  • Challenging design and fabrication timeline.


  •  Final design compliance.
  •  Machine design heavily optimised to improve fatigue life as much as practicable.
