Equipped with leading-edge equipment and machinery, we have strategically located workshop facilities in Mackay, Queensland.

Each workshop is purpose-built to support the manufacture, fabrication, and repair of large surface mining equipment.

We have a long history of providing manufacturing and fabrication services, and our facilities support numerous resources and infrastructure clients – from large multinational businesses to new entry investors.

In addition to an extensive history in manufacturing draglines, our team has experience in constructing coal handling and preparation plants, stacker/reclaimers, conveyor systems, and ship loaders.

With a focus on delivering solutions to meet the specific requirements of clients, across our workshops we provide services for structural steel and ferrous and non-ferrous metals, including:

  • All major and minor fabrication
  • Maintenance and overhauls
  • Plate work, and
  • Repair and refurbishment.

We have extensive experience in Dragline manufacture and erection, having erected 17 Draglines, manufactured 20 Dragline bases in the Mackay workshop and erected over 20 Dragline bases onsite (either through new installations or replacements).


Our Mackay workshop is purpose-built for manufacturing dragline bases. The 3,300sqm workshop has 5x50 tonne cranes with 200-tonne lift capacity to a height of 10 metres.

It has a clear floor space of 25m x 25m (625sqm) at both ends of the workshop allowing for the simultaneous manufacture of two dragline bases leaving a large unimpeded floor area to allow sections to be manufactured and aligned ready for quicker site erection.
