Detailed Description:

• The DUO hydraulic grading bucket, with a width of 1800 mm and a high volume capacity of 610 liters, is custom-engineered for advanced, heavy-duty applications in large-scale working environments.

  It delivers excellent precision and superior operational efficiency even under demanding terrain and structural site conditions.

  This heavy-duty attachment is ideal for tasks requiring high productivity, such as deep foundation excavations, mass land leveling, and bulk material handling, guaranteeing maximum reliability with every duty cycle.

  Engineered to fulfill industrial requirements, this grading bucket provides exceptional structural stability and leveling accuracy, making it a professional-grade asset for complex civil engineering and earthmoving operations.

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

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

  The structural design incorporates an extra-thick 18 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 HB500 cutting edge measuring 150x16 mm.

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

  Longitudinal 8 mm HB400 internal reinforcement ribs provide total resistance against frame twisting and high torsional forces.

  With dimensions of 1800 mm in width, 840 mm in length, and an extended height of 1090 mm, this bucket achieves an optimal payload-to-width ratio for substantial earthmoving jobs.

  Its robust unladen weight of 643 kg supplies a stabilizing counter-ballast to the carrier machine, facilitating exceptionally smooth and controlled hydraulic manipulation via its dual-cylinder system, which provides a flexible 34.5° tilt angle.

  This hydraulic grading bucket is purpose-built for mid-to-heavy excavators with an operating weight ranging from 14 to 18 tonnes, providing an effective match for heavy 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 slope 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, utilities installation, and general site preparation, serving as a dependable, highly durable investment for industrial multi-season deployment.
