When it is hard rock that the standard loader bucket is being used to move, the cutting edge, side plates, bottom, as well as stress concentration areas of the bucket will wear out very fast.
Heavy-duty areas are reinforced with Hardox 450 abrasion-resistant steel (10–25mm).
Using 3D stress analysis helps optimize the reinforcement of the structure, not just its thickness.
Changeable cutting edges and wear parts help reduce long-term running costs.
This design approach inherently guarantees excellent breaking and filling of the bucket, even when the materials are hard rock, ore, or high-impact.
Main Material: Hardox 450high wear-resistant steel, 10–25mm thick.
Cutting Edge System: Replaceable cutting edges with ISO 898-1 high-strength bolts.
Structural Design: Reinforced side walls and bottom to strengthen high-impact zones.
Capacity Range: 1–5 m³, varies according to yourequipment and working conditions.
Equipment Compatibility: Support majority of the loaders, such as Caterpillar, Komatsu, etc.
For more extreme conditions, additional structures for targeted reinforcement areavailable.
Custom-made according to the loader type and pin dimensions.
The reinforcement is material-type and abrasion-level adaptable.
Side teeth, cleaning edges, or specific wear-resistant structures can be selected.
Design directly from customer drawings, samples, or from the working condition descriptions.
