The Story
1B Riddle Bucket / Shaker Bucket 24" / 600mm
The 1B Riddle Bucket is a 24-inch shaker (riddle) bucket designed to screen material directly on the job site. It features a 24" (600mm) width with precise mounting geometry: 25mm diameter pins, a 95mm dipper gap, and 90mm pin centres. This configuration supports attachment to compatible excavator linkages and enables on-site screening to separate fines from larger material. For more information, refer to the accompanying videos.
- Size and mounting geometry: 24" / 600mm bucket width; 25mm diameter pins; 95mm dipper gap; 90mm pin centres.
- Shaker (riddle) action: On-site screening capability that separates fines from larger particles as you dig, improving material quality for reuse or backfill.
- Operational efficiency: Reduces the need for a separate screening step, helping speed up workflows on trenching, backfill, and material sorting tasks.
- Compatibility notes: Designed to fit attachments using 25mm pins with the specified dipper gap and pin-centre measurements; verify compatibility with your existing hardware before use.
Benefits: By combining digging and screening, the 1B Riddle Bucket helps you sort material on the fly, cut handling time, and improve reuse of on-site material. It’s a practical choice for mid-sized excavators engaged in foundation work, trenching, site clearance, and material recovery, offering focused, reusable material with clear separation of fines and larger aggregates. Regular checks of pin fit and spacing will help maintain reliable performance across jobs.
