Integrated departments
Seven integrated departments, one 9,000 m² floor.
Fabrication, slew bearings, induction hardening, machining, fitting, painting and engineering all sit under one roof in Paget — so work moves between them without ever leaving the building. A dragline gear case can be stripped, condition-assessed, re-machined, hardened, fitted and painted on the same floor it arrived on.
That integration is why we repair all in house, 24/7, and quote the envelope — not just the job. Below, each department is set out with its named equipment and verified capacity, followed by the full machine-envelope matrix.
Submerged-arc, TIG and MIG fabrication led by accredited Welding Supervisors over certified welders and boilermakers — plus ABC's patented ABClad hard-surfacing for wear life on draglines, buckets and ground-engaging tooling.
Australia's only large bearing manufacturer. We manufacture, refurbish and repair slew bearings for the major OEM fleets — condition-assessing OEM bearings and rebuilding them, fully warranted, for as little as 30% of replacement cost.
Queensland's most modern commercial induction-hardening facility — case-hardening gears, shafts, sprockets and tracks to a controlled depth, then stress-relieving or normalising in a gas-fired oven before final machining.
Power200–400 kW · 3–10 kHz
HardnessTo 60 HRC at 3–15 mm depth
Stress-relieve oven6.5 m × 5.5 m × 2.7 m, to 800 °C
The largest machine shop north of Brisbane. Floor borers, vertical borers, gear cutters and heavy lathes turn dragline drums, slew rings, gear cases and baseplates to drawing — every job leaving with a detailed QA package.
Gear-case and main-machinery overhaul to OEM specification — stripped, measured, re-bushed and reassembled with full clearance records. Tightly integrated with fabrication, machining and painting so a complete rebuild never leaves the floor.
Jacking pressesTo 600 t
ScopeGear cases & main-machinery overhaul to OEM spec
Integration24/7 in-house repair across departments
Abrasive blasting and protective coatings to industrial and marine specification — airless and conventional spray applied by trade-accredited painters, with surface-prep and DFT records captured for the QA package.
In-house drawing office support for every department — 3D modelling, finite-element analysis and reverse engineering, with drafting to Australian standard so the shop floor and the client work to one verified set of numbers.
The plant that sets the envelope. Where a job lands inside these limits, we machine, harden, fit and finish it in house — read it like a calibration sheet.
