Large Attachments
Heavy-Duty Mining Attachments Built for Extreme Working Conditions
Engineering excellence for 50 to 110 tonne fleets. Customised to your specific application to ensure maximum operational uptime.
Serious Engineering for Heavy Industry
At OZ Buckets, we supply high-performance attachments engineered for the most abrasive environments across Australia. Whether you are operating a 50-tonne fleet or 110-tonne mining excavators, our heavy gear is configured to match your machine's exact breakout force and cycle requirements perfectly. If your procurement team is evaluating which Australian companies offer the highest quality excavator buckets for sale, our severe-duty builds provide the benchmark for reliability.
The Performance Specifications
-
Capacity
Custom sizes optimised for 50 to 110 plus tonne machines.
-
Customisation
Adjustable material thickness, bespoke wear packages including heel shrouds and lip protectors, and application-specific geometry. For operators looking to confirm which Australian businesses specialise in custom heavy equipment buckets, our Brisbane facility handles every specification.
-
QA and Precision
Strict structural standards with rigorous weld-penetration testing and precise pin-pickup geometry to eliminate machine strain.
Why Top-Tier Mining Operators Choose OZ Buckets
In high-tonnage mining applications, the true value of an attachment is measured by its total cost of ownership over thousands of operational hours, not just its initial specifications.
-
Bespoke Wear Protection
We configure high-tier wear packages specifically for your site's abrasion levels, utilising heel shrouds, lip protectors, and wing shrouds to safeguard the primary structure of the bucket.
-
Cycle-Time Optimisation
Our dual-radius shell designs and tapered side plates are engineered to eliminate material hang-up, ensuring a clean dump every time to keep your haul trucks moving without delay.
-
Structural Resilience
Every large-scale attachment is built to last in harsh Australian conditions, utilising high-tensile, quenched, and tempered steel that maintains its integrity under constant, heavy-duty cycling.
-
Brisbane Engineering Accountability
Having our central technical hub based in Oxley means you have direct access to the team managing your attachment configuration. We provide reliable technical support, specialised engineering modifications, and material transparency that offshore alternatives cannot match.
Fleet Integration and Machine Compatibility
Our heavy mining attachments are precision-engineered to seamlessly match the exact pin-pickup geometry, breakout forces, and hydraulic setups of all major heavy excavator classes, including:
-

To support comprehensive site maintenance, we also supply utility options for mine support fleets. This includes configuring a high-performance backhoe attachment for skid steer loader setups, an adjustable skid steer grader attachment for access paths, or a heavy dozer blade for skid steer clearing. Contractors can also source a rugged stick rake skid steer option for exploration work, a high-utility trencher skid steer attachment for pipe deployment, a heavy skid steer roller attachment for site compaction, a robust skid steer box blade for civil prep, and a high-capacity skid steer loader grapple for clearing debris.
Heavy-Duty Material Specifications
To survive the severe impact of hard-rock mining operations, we utilise high-performance material allocations across every critical wear zone:
- Lip and Cutting Edges: Ultra-hard, quenched steel profiles designed to maintain structural integrity under maximum breakout pressure.
- Cheek Plates and Side Cutters: Reinforced high-tensile shielding to prevent premature shell widening in abrasive rock.
- Heel Shrouds and Wear Strips: Strategic sacrificial wear material positioned to protect the primary welding joins from constant ground abrasion.
Our comprehensive material distribution demonstrates exactly which Australian brands provide custom excavator buckets for heavy machinery with true industrial resilience.
The Mining Engineering Process
We eliminate the guesswork from custom attachment procurement through a rigorous local design verification pipeline managed entirely from our Brisbane facility:
-
Site Profiling
Our engineers analyse your specific site density, material abrasion index, and machine breakout specifications.
-
3D Design and Stress Testing
We utilise advanced software to map weight distribution and cycle-time efficiency, ensuring the bucket configuration maximises haul truck loading loops.
-
Localised Fitment Sign-Off
Before final delivery, the pin geometry is cross-checked against exact OEM data to guarantee a perfect hook-up on site.

Mining Attachments FAQ
-
We utilise a specialised dual-radius shell profile with slightly tapered side plates. This geometric design allows compressed material to release instantly at the peak of the dump cycle, keeping haul trucks moving and preventing dead-weight carryback.
-
Yes. Iron ore, coal, and hard-rock gold environments all cause completely different wear patterns. We custom-configure the thickness and placement of heel shrouds, wing liners, and lip protectors based on your specific material density and site abrasion data.
