Changsha Mingyi Machinery Equipment Co., Ltd., based in China's industrial hub of Hunan, engineers robust excavation solutions for extreme conditions. Our Hardox 450 Excavator Bucket is precision-built for operators demanding maximum productivity in abrasive environments. Combining superior material science with heavy-duty construction, this attachment significantly reduces downtime while increasing load retention efficiency.
Engineered specifically for:
- High-impact rock excavation
- Continuous mining operations
- Demolition debris handling
- Quarry overburden removal
Core Engineering Advantages:
- Hardox 450 Armor: 450 HBW hardness steel provides 3× better abrasion resistance than standard buckets, with maintained impact toughness at temperatures down to -40°C.
- Optimized Geometry: Curved profile design enhances material roll-in while minimizing spillage during high-reach operations.
- Double-Layer Reinforcement: Critical stress zones feature 25mm additional plating at hinge points and heel plate.
- Modular Wear System: Bolt-on ADI (Austempered Ductile Iron) teeth and side cutters enable rapid replacement without welding.
Technical Specifications:
| Parameter | Value Range | Notes |
| Bucket Width | 900-1800 mm | Varies by excavator class |
| Side Plate Thickness | 16-40 mm | Tapered reinforcement |
| Pin Bore Diameter | 70-120 mm | ISO 14583 compatible |
| Weight Efficiency | 15-25% lighter | vs. equivalent AR400 buckets |
Operational Benefits:
- Extended Service Intervals: Field tests show 30-40% longer lifespan in granite quarry applications versus standard buckets
- Fuel Savings: Reduced empty weight allows higher payloads per cycle, decreasing fuel consumption per ton
- Reduced Maintenance Cost: Modular wear components cut replacement time by 65% vs. welded designs

Q2: Are adapter systems included?
A: Buckets are manufactured to match your specific excavator's pin configuration. Adapter plates available upon request.
Q3: What warranty is provided?
A: 12-month structural warranty against manufacturing defects. Wear components have 6-month coverage.
Q4: Can I request extra reinforcement?
A: Yes. We offer XT (Extra Thick) packages with 30% additional plating in high-abrasion zones.
Q5: How are buckets shipped?
A: Standard sea freight in 20/40ft containers with anti-corrosion coating. Air freight available for urgent orders.
Q6: Do you provide bucket teeth?
A: Yes. We supply compatible ESCO®-style teeth and shrouds as a bundled package.
Q7: Can I get buckets for 50+ ton excavators?
A: Custom designs up to 6m³ capacity available. Submit your machine model for engineering review.
Q8: How do I verify compatibility?
A: Provide excavator model + required pin center measurements. Our technical team will confirm specifications within 24hrs.
