Detailed Description:

• The DUO rigid grading bucket, featuring a functional width of 1800 mm and a high-volume capacity of 552 liters, is a high-performance attachment engineered for large-scale, demanding earthworks.

• It delivers excellent precision and high operational throughput even under heavy-duty site conditions.

• This rugged tool is highly versatile, making it perfect for a wide range of applications including foundation excavations, ditch digging, land leveling, and bulk material transport, ensuring superior efficiency in every maneuver.

• Designed to fulfill strict industrial requirements, this grading bucket provides outstanding structural stability and profiling accuracy, making it a professional-grade asset for complex civil engineering and earthmoving operations.

• It is fabricated entirely from premium structural steel—featuring a heavily reinforced 8 mm thick S355 J2 main shell paired with 6 mm S355 J2 side walls—offering excellent structural rigidity and rugged resistance against mechanical impacts, wear, and structural fatigue.

• S355 J2 steel is selected for its high tensile strength and anti-corrosive properties, securing an extended service life during intensive, long-term operational use.

• The structural design incorporates a 15 mm HB400 steel plate reinforcing the cutting edge base, which works alongside an aggressive dual-blade assembly.

• This configuration utilizes a heavy-duty main HB500 cutting edge measuring 250x25 mm and a secondary rear HB400 cutting edge measuring 150x16 mm.

• This combination delivers supreme protection against severe abrasive wear and heavy-impact shocks encountered when processing compacted, rocky, or hard soils.

• Longitudinal 8 mm S355 J2 internal reinforcement ribs provide total resistance against frame twisting and high structural stress.

   

• With dimensions of 1800 mm in width, 820 mm in length, and a compact height of 590 mm, this bucket achieves an optimal payload-to-width ratio, remaining highly efficient even when operating in tight or restricted work zones.

• Its unladen weight of 427 kg supplies a solid, stabilizing counterweight to the carrier machine, facilitating smooth and controlled manipulation across uneven and difficult terrains.

• This rigid grading bucket is purpose-built for mid-sized excavators with an operating weight ranging from 12 to 14 tonnes, providing an effective match for infrastructure and site development equipment.

• It is fully compatible with major global machinery brands, including Atlas, Bobcat, Caterpillar, Doosan, JCB, Kubota, Volvo, Hyundai, Hitachi, and Komatsu, fitting seamlessly into diverse, multi-brand corporate fleets.

• The ergonomic mold profile guarantees high material retention during movement and clean dumping cycles, giving operators absolute control during precision profiling, ditching, and final embankment trimming.

• Its standard attachment interface allows for quick coupling and uncoupling to minimize non-productive downtime.

• Providing solid performance on uneven and loose surfaces, this tool vastly increases operational efficiency across road building, water/sewer utilities installation, drainage systems, and general site preparation, serving as a dependable, highly durable investment for industrial multi-season deployment.
