Engineered for maximum durability in high-impact environments, this 1.8m³ Heavy-Duty Rock Skeleton Bucket (Screening Bucket) is designed for efficient material separation, land clearing, and mining applications. Built entirely from premium high-strength manganese steel, this bucket easily separates large rocks, concrete rubble, and debris from soil and sand, significantly reducing cycle times and operational costs.
Key Technical Specifications
Capacity: 1.8 m³ (Ideal for large-scale earthmoving and mining excavators)
Material: Premium High-Strength Manganese Steel Plate (Q345B/NM400 equivalent for superior wear and impact resistance)
Cutting Edge (Tooth Plate): 60mm Thickened Base Plate
Side Plates: 40mm Reinforced Structural Plates
Ear Plates (Hitch Brackets): 40mm Heavy-Duty Mounting Ear Plates
Screening Grid: 50mm Solid Round Steel Bars
Bucket Teeth: Heavy-Duty Komatsu PC400-compatible Bucket Teeth & Adapters
Premium Design Features
Reinforced Structural Integrity: Featuring a ultra-thick 60mm cutting edge alongside 40mm side and ear plates, this bucket is built to withstand massive breakout forces from large excavators without deformation.
High-Efficiency Grid Design: Constructed with 50mm solid round manganese steel bars, the screening grid offers optimal spacing for fast material sorting while maintaining maximum structural stiffness under heavy rock loads.
Mining-Grade Ground Engaging Tools (GET): Equipped with standard Komatsu PC400 style bucket teeth and shroud protection to ensure exceptional penetration, high wear resistance, and easy replacement.
Wear-Resistant Side Protectors: The side profiles feature heavy-duty round wear buttons/pads to protect the structural welds during abrasive rock handling.
⚙️ Technical Specifications (Deep-Dive)
| Component | Professional Specification | Why it Matters |
|---|---|---|
| Capacity | 1.8 m³ (Cubic Meters) | High-volume throughput for large-scale earthmoving. |
| Tooth Base Plate | 60mm Thickened Armor Plate | Prevents bending and cracking under extreme impact. |
