The 360° Hydraulic Rotary Tilting Screening Bucket (also known as a Rotary Tilting Skeleton Bucket) is a premium, multi-functional excavator attachment engineered for high-efficiency material sorting, screening, and grading. Unlike a standard fixed skeleton bucket, this advanced attachment combines two critical functions into one unit: By integrating 360-degree continuous rotation and ±45-degree dual-axis tilting into a heavy-duty skeleton structure, this bucket allows operators to dig, tilt, rotate, and screen materials at any angle without repositioning the excavator. It is the ultimate one-stop solution for complex landscaping, demolition, and pipeline backfilling projects.
1. 360° Continuous Hydraulic Rotation
Equipped with a heavy-duty hydraulic rotary motor and a robust sleking bearing, providing infinite 360° clockwise and counter-clockwise rotation.
Enables exceptional flexibility in narrow spaces, deep trenches, and complex job sites, maximizing operator control and productivity.
2. ±45° Dual-Direction Tilting Mechanism
Powered by a high-tonnage, dual-acting hydraulic cylinder that allows the bucket to tilt up to 45 degrees left and right.
Perfect for matching precise ground angles, cutting slopes, and grading uneven terrain while simultaneously screening material.
3. High-Efficiency Screening Grid (Skeleton Design)
Features a precision-spaced mesh/grid bottom that allows soil, sand, fine aggregates, and water to pass through instantly while retaining larger rocks, concrete chunks, and debris. Drastically reduces cycle times by combining excavation and sorting into a single workflow.
4. Interchangeable Mesh/Grid Plates
Versatile Sizing: The internal screening plates can often be customized or interchanged (e.g., 20mm, 30mm, 50mm, or 100mm) to produce the exact grade of aggregate your project requires.
One Bucket, Multiple Jobs: Ideal for sorting everything from fine topsoil for landscaping to large rocks for harbor construction.
5. Heavy-Duty, Wear-Resistant Construction
Ritical components, especially the rotating drum and the cutting edge, are made from NM500 wear-resistant steel to handle the extreme friction of rock and concrete recycling.
Heavy-Duty Drive System: Equipped with a high-torque hydraulic motor and reinforced bearings designed to withstand the massive radial loads during full-load rotation.
Structural inner reinforcement ribs run along the grid to prevent the screen mesh from bending or warping under high-load excavation.
Built with premium seals and a heavy-duty enclosure to ensure reliable hydraulic performance in mud, dust, or underwater dredging applications. All high-pressure hydraulic lines are wrapped in high-density spiral protective sleeves to prevent abrasions and cuts from jagged rocks and concrete debris.
6. Low Maintenance & Easy Operation
Plug-and-Play: Connects directly to the excavator’s auxiliary hydraulic lines (Hammer/Tilt lines).
Simple Greasing Points: Centralized lubrication points ensure the rotating mechanism stays smooth with minimal daily maintenance.
7. Significant Cost Savings (ROI)
Reduce Transport Costs: Sift and reuse materials directly on-site. You only transport the waste you can’t use, saving up to 60% on truck and disposal fees. Zero Manual Labor: Automates the sorting process, eliminating the need for extra workers on the ground with manual screens.

Core Applications
Landscaping & Slope Grading: Perfect for trimming road/railway slopes, leveling topsoil, and screening out roots or rocks on inclined surfaces.
Demolition & Recycling: On-site separation of concrete, bricks, and masonry from fine dirt, optimizing waste sorting and reducing material transport costs.
Pipeline & Trench Backfilling: Allows operators to screen out sharp rocks directly over the trench, ensuring only fine soil is used to safely backfill and protect pipes or cables.
River Dredging & Environmental Cleaning: Efficiently scoops up wet debris; water and silt drain instantly through the grid, leaving only solid waste for disposal.
Maximum Efficiency (4-in-1 Design): Combines digging, screening, tilting, and rotating into one attachment, minimizing the need to switch tools on-site.
Drastic Cost Savings: Turn waste into profit by sorting usable aggregates and backfill materials right on the job site, saving on disposal fees and truck transport costs.
Premium OEM Quality: Engineered as a direct-fit attachment for major excavator brands (Komatsu, Caterpillar, Hitachi, Sany, etc.), offering factory-direct durability and competitive margins for global distributors.
Turning Waste into Gold – How the HWX Jinan Changhao Rotary Screening Bucket Saved $8,000 in One Week
Location: Brisbane, Australia
Project: Large-Scale Site Preparation & Landscaping
Machine: Sany SY215 (21-Ton Excavator)
Attachment: 20-Ton Hydraulic Rotary Screening Bucket (50mm Mesh)
The Challenge: The High Cost of “Waste”
A prominent site-preparation firm in Brisbane was struggling with a 5,000-ton pile of mixed demolition debris, river silt, and rocks.
The Problem: Transporting this “mixed waste” to the landfill was costing them $250 per truckload.
The Inefficiency: They tried using a static skeleton bucket, but the wet, sticky river silt kept clogging the bars, forcing the operator to stop and clean it manually every 15 minutes. Productivity was at a standstill.
The Solution: Active Rotation, Zero Clogging
The project manager decided to switch to the Hydraulic Rotary Screening Bucket. Unlike a static bucket, the rotary model uses a high-torque hydraulic motor to tumble the material 360 degrees.
Active Sifting: The continuous tumbling motion prevented the wet silt from sticking, allowing the fine soil to pass through the 50mm mesh instantly.
Bi-Directional Power: The operator used the bi-directional rotation to “shake” stubborn clay chunks, breaking them down into sifted soil in seconds.
The Outcome: From Waste to Revenue
In just seven days, the results were transformative:
Massive Cost Savings: By sifting the material on-site, they separated the “waste” into high-quality topsoil (reused for landscaping) and clean 50mm+ rock (sold to a local road project as aggregate).
Reduced Transport: They eliminated 32 truck trips in the first week alone, saving approximately $8,000 in disposal and fuel fees.
Speed: The rotary bucket completed the sorting process 3 times faster than the previous method.
Client Feedback:
“Before the Rotary Bucket, we were literally throwing money away at the landfill. Now, we produce our own topsoil and aggregate on-site. The bi-directional rotation is a lifesaver for wet materials. It paid for itself in less than two months.” — Mark T., Senior Site Manager.
