The High-Performance Skeleton Buckets (Sieve Buckets) are engineered for the primary sorting of rocks, debris, and industrial waste. Designed for excavators from 3 to 45 tons, our skeleton design allows fine soil and sand to pass through while retaining larger materials for secondary processing. Whether in demolition site clearing or quarry sorting, our buckets significantly reduce handling costs and increase project ROI.

Wear-Resistant Armor: We use authentic NM400 for the bottom ribs and side cutters to withstand abrasive rock sorting environments.
Customized Grid Sizing: The spacing between horizontal and vertical ribs can be tailored to your specific screening requirements (e.g., separating 80mm+ aggregates).
Reinforced Rib Structure: Every rib intersection is double-welded to prevent stress cracking during heavy-duty vibration and high-load screening.
