1. All-Scenario Adaptability: 10-Minute Attachment Switch

  • 2.4-2.8m³ bucket capacity (2.4m³ light-duty standard), compatible with 8 attachments like hydraulic hammers and rotary grabs, enabling quick shifts between urban demolition and forestry operations.

  • 7.19m max digging depth +11.74m max reach covers 10m-wide work surfaces for river cleaning or 5m-deep pipeline trenches.

2. Cummins Power: 30% Fuel Savings

  • QSM11-C375XCEC engine delivers 260kW net power and 1,898N·m torque@1,300rpm, crushing C30 concrete 25% faster than peer models.

  • Tier 3/Stage III emissions + Donaldson air filter ensure operation up to 3,000m altitude, with diesel consumption as low as 210g/kWh.

3. Precision Hydraulics: Smooth Composite Movements

  • Two variable piston pumps (2×453.6L/min flow) +35MPa pressure enable 0.8m/s boom lifting and 8.6rpm swing speed, achieving 120 buckets/hour for truck loading.

  • 6 operation modes (Power/Eco/Fine etc.) allow "Fine Mode" for ±3cm bucket control in landscaping projects.

4. Military-Grade Durability: 15-Minute Fault Warning

  • 600mm triple-grouser tracks +51 track shoes per side, 86kPa ground pressure prevents sinking in wetlands. ROPS cab passes 2m drop test.

  • Color LCD monitors 12 parameters (hydraulic temp, filter life), warning 15min ahead of faults. Service intervals extended to 500 hours.

5. Optional Upgrades for Flexibility

  • 360° panoramic camera + hydraulic quick coupler supports special attachments like vibrating rammers and electric suction cups.

  • Climate-controlled cab (-25℃~+45℃) with air suspension seat reduces cold-start time to 30s in winter.
