  • The X-type integral welded high-reliability chassis features high rigidity and stability, and is tailor-made for heavy-duty operations.

  • Slewing motor - Hengli, cross-buffered design, prevents abrupt stop during sudden retraction, avoids damage to gears and impact on the slewing bearing. Soft start and soft stop structure.

  • Slewing bearing - Ma'anshan Fangyuan, designed for heavy-duty operation, high reliability.

Travel Motor - Hengli

  • Large displacement low-speed mode: powerful climbing, no sluggishness

  • High-speed mode: fast travel, high efficiency in site transitions

  • Automatic locking when stopped, preventing rollback

  • Equipped with cross-flow buffer, avoids gear impact, longer lifespan

  • The boom structure connecting parts are cast, resulting in minimal deformation and stress, and reducing the likelihood of cracking.

  • The boom tilting frame is cast as a single piece, providing high rigidity and reducing cracking, making it suitable for heavy-duty construction environments.

  • Excellent durability and long service life.

  • Tail-less slewing, tail-end turning radius 870mm

  • Overall width 1580mm

  • Meets the requirements of narrow working environments

  • The boom and stick are each equipped with explosion-proof valves to effectively prevent them from settling and falling due to hydraulic hose rupture.

  • The bulldozer blade cylinder is equipped with a hydraulic locking valve to prevent the hydraulic blade from settling when loading and unloading from the flatbed truck.

  • This improves the overall safety of the machine.

  • The main control valve is installed on the side cover of the machine, making maintenance and pipe replacement convenient.

  • The engine compartment, radiator, and filter compartment can be fully opened, providing ample maintenance space.

  • Large fuel tank. 52L capacity, sufficient for 3 days of work.

The cab features a highly interactive human-machine interface, making operation simple and easy.

Operators will not experience fatigue even after prolonged operation.

  • Standard boom 2.1m, standard stick 1.2m

  • Extended boom 2.2m, extended stick 1.4m available upon request

  • Front working device can be equipped with a two-way control circuit auxiliary, such as a rotatable bucket.
