Fully upgraded, they efficiently meet diverse project needs such as earthmoving, foundation work, urban renovation, farmland improvement, water conservancy, mine slope maintenance, and road repair.

1. The bucket adopts advanced simulation optimization technology to refine its shape based on digging trajectories. Key areas use wear-resistant materials to reduce digging resistance and power loss. Bucket capacity is upgraded to 0.8 m³.

2. Equipped with the Cummins QSF3.8 engine as standard, delivering 93 kW rated power with greater power and torque reserves to ensure strong performance. Optional Kubota V3800 engine available, compliant with EU Stage V and EPA standards.

3. Fitted with Kawasaki positive flow hydraulic system for precise power matching, improving overall energy efficiency by 5%–8%.

4. Features a high-quality main valve from a well-known brand and a high-performance controller with optimized algorithms, enabling more responsive control and improved human-machine interaction.

5. The lower part of the arm is reinforced with an extended wear plate to resist deformation from rock impact. The boom is strengthened in both the middle and rear sections for higher durability and extended service life.

With technological innovation, our product configuration and parameters will continue to change without notice; 

if there is any doubt, the specific confirmation of our international trade sales shall prevail.
