North Queensland Bulk Ports Corporation engaged CMA Contracting (now a Delta Group company) in 2011 to complete the demolition of a Stacker Reclaimer (SR2).

The scope of works included:

  • Demolition of industrial operating plant, including site preparation and systems purge (oil, fuel lines and other contaminants).
  • Staged deconstruction of plant – Tripper, Elevating Conveyor and Stacker.
  • Protection of adjacent structures – ‘live’ conveyor line and SR1 machine.
  • Emissions, noise and vibration controls.
  • Transport logistics, including traffic management and supervision.
  • Recycling of uncontaminated waste materials
  • Removal of asbestos and hazardous waste, including hydrocarbons.
  • Asset recovery, including salvage for reuse and sale.

All aspects of our demolition works programme addressed the high risk of over-balancing the 1,500t SR2 suspension machine. The programme also had to address an operational or ‘live’ conveyor line servicing the port’s continuous rail and shipping operations – running through the frame of SR2 to another machine (SR1) which remained fully operational.

To complete the demolition we mobilised a fleet of specialised plant, including 80t – 280t mobile and crawler cranes, 86ft – 120ft boom lifts, 35t excavators and precision attachments, articulated trucks and telehandlers.

Our meticulously designed and executed programme successfully deconstructed the 45 metre high structure without incident or disruption. We also salvaged 300t of plant and equipment, including parts for the remaining Stacker Reclaimer (SR1).
