Core Advantages
1. Stable Power Output & Good Adaptability to Poor Fuel Quality
Powered by reliable Doosan DB58TIS 6‑cylinder turbocharged diesel engine, rated power 110 kW (148 hp) @1950 rpm. Adopting mechanical fuel injection design, it has strong fuel compatibility and low requirement for fuel cleanliness. Multiple working power modes are selectable to balance digging performance and fuel consumption.
- Operating weight: 21500 kg
- Fuel tank capacity: 300 L
- Maximum bucket digging force: 136.2 kN
- Gradeability: 35° Strong low‑speed torque adapts to long‑time continuous earth‑moving and light rock operation, performing steadily in remote construction sites with limited maintenance conditions.
2. Mature Hydraulic System & Practical Working Parameters
Adopts load‑sensing hydraulic system with independent pilot control, realizing smooth compound movements and easy operation. The e‑EPOS electronic control system optimizes flow distribution and reduces unnecessary energy loss.
Key working parameters:
- Maximum digging depth: 6630 mm
- Maximum ground‑level reach: 9910 mm
- Maximum dumping height: 6490 mm
- Standard bucket capacity: 1.28 m³
- Main pump maximum flow: 430 L/min (2×215 L/min)
- Main hydraulic system pressure: 34.3 MPa
Two‑speed travel system matches reinforced heavy‑duty undercarriage. Robust track frame and wear‑resistant track shoes cope with muddy, stony and complex construction terrain.
3. Spacious Cab & Practical Safety Configuration
Large‑space ergonomic cab with good all‑round visibility. Comfortable adjustable suspension seat reduces operator fatigue during long‑hour shifts. Intuitive instrument panel displays real‑time working data and fault codes. ROPS‑compliant cab structure improves roll‑over protection. Simple control layout makes operation easy for different operators. Optional air‑conditioning system adapts to high‑temperature outdoor construction environment.
4. Simple Maintenance & Low Running Cost
Mechanical engine structure brings convenient overhaul and low failure rate. Main service points are centrally arranged for quick daily inspection. Hydraulic pipelines adopt reliable sealing to reduce oil leakage risk. Parts are widely available globally at competitive prices. Simple whole‑machine structure shortens repair time and cuts total ownership cost, very suitable for equipment rental business.
