Seven departments
Work moves between them without leaving the floor.
Fabrication, slew bearings, induction hardening, machining, fitting, painting — with engineering across all of it. The integration is the capability: it's how a gear case goes from strip to survey to re-machine to coat without a truck movement.
01 — Steel fabrication & welding
A fabrication building sized for draglines.
Small detailed work to large structural sectionalised weldments — dragline booms, buckets, walking frames, stacker-reclaimers, crushers and screens — with accredited Welding Supervisors leading certified Welders and Boilermakers.
- Fabrication building 90 × 30 × 16 m — with 4 dragline bucket arch pits
- Workpieces to 150 t — sheave rotators to 5 m diameter
- Submerged-arc, TIG and MIG — booms, manipulators, rolls and jigs
- Patented ABClad hard-surfacing — wear reclamation
02 — Large-diameter slew bearings
The only large bearing manufacturer in Australia.
Manufacture, refurbishment and repair for hydraulic excavators, cranes and industrial plant — Komatsu, Liebherr, O&K, Caterpillar and Hitachi — backed by the Worldwide Slew Bearing Alliance with BMT, a global bearing-rebuild network.
- OEM bearings condition-assessed, rebuilt and warranted from 30% of replacement cost
- In-situ change-out — integrated excavator jacking and support stands
- Site-based condition monitoring — car-body drive-out options
03 — Induction hardening & heat treatment
Queensland's most modern commercial induction facility.
Surface hardening for slew bearings, rope drums and sheaves, shafts, pins and bushes, load rollers and drive sprockets — offered commercially to external customers, not just our own rebuilds.
- Induction units 200–400 kW at 3–10 kHz
- Hardening to 60 HRC at 3–15 mm case depth
- Gas-fired stress-relieve and normalise oven 6.5 × 5.5 × 2.7 m to 800 °C
04 — Machining
The department the claim is named after.
The largest machine shop north of Brisbane — CNC floor and vertical borers, long-bed machines, mills, planers and radial-arm drills, with detailed QA packages provided with all work completed.
- CNC floor borer — 13 m travel, 6 m column, workpieces to 150 t
- CNC vertical borers to Ø 5 m — twin-post to Ø 3.5 m, 18 t tables
- CNC gear cutting — external and internal to Ø 5.5 m
- CNC lathes for workpieces over 40 t
05 — Fitting
Stripped, measured, recorded — rebuilt to OEM spec.
Gear case and main machinery overhaul: every assembly cleaned, stripped, assessed, measured and recorded before it's rebuilt. Fitting works alongside fabrication, machining and painting — which is what lets ABC repair all in house, 24/7.
- Jacking presses to 600 t
- Gear-case and main-machinery overhaul to OEM spec
- Integrated with fabrication, machining and painting — one floor, 24/7
06 — Industrial painting
Blast and coat, to industrial and marine spec.
Abrasive blasting and protective coatings at industrial scale, applied by trade-accredited painters with QA on the coating system — the last step before a rebuild leaves the floor.
- Protective coatings to industrial and marine specifications
- Airless and conventional spray — high-pressure cleaning, maintenance painting
- Trade-accredited painters — QA on all coating work
07 — Engineering & design
Drawn, analysed, reverse-engineered.
The design office behind the floor — 3D modelling, structural analysis and drafting that turns a worn component with no drawings into a manufacturable, optimised replacement.
- SolidWorks 3D modelling and FEA structural analysis
- Drafting to AS1100 — conceptual and workshop drawings, AutoCAD
- Reverse engineering and design optimisation
Equipment
The machine envelope.
If the job fits these numbers, it fits the building — and the 10 × 10 × 35 m door means getting it in is rarely the problem.
