KN120-9 Compact Hydraulic Crawler Excavator For Urban Construction
KAISAN Crawler Excavator KN210-9
The KN210-9 (21.3-ton) excavator delivers robust power and efficiency for demanding earthmoving. Its core strength lies in the potent Cummins 6BTAA5.9 turbocharged engine (133 kW) driving a high-performance hydraulic system with twin main pumps (215 L/min each), generating significant digging forces (112 KN bucket force). This enables powerful excavation with its 1 m³ bucket, achieving a maximum digging depth of 6.5 meters and dumping height of 6.6 meters. Designed for challenging terrain, it features rugged triple-grouser tracks providing stability with low ground pressure (46.5 kPa) and a strong 35° climbing ability. Combining substantial power, efficient digging capacity, and reliable off-road mobility, the KN210-9 is built to tackle core construction tasks effectively.
Model: KN210-9 (133KW CUMMINS/ISUZU Turbocharged Engine)
Weight: Net 21,300 kg; Operating 21,500 kg
Robust Powerplant:
Equipped with a Cummins 6BTAA5.9 turbocharged engine (133 kW / 2000 rpm), delivering reliable power for heavy-duty excavation while meeting Euro II emissions.
High-Efficiency Hydraulics:
Twin EDDIE main pumps (215 L/min × 2 & 37.3 MPa) ensure responsive operation and strong digging forces, with 112 kN bucket force for efficient material handling.
Substantial Digging Performance:
Achieves a max digging depth of 6.5m and max dumping height of 6.6m, supported by a versatile 1 m³ bucket and optimized 5.7m boom + 2.9m arm configuration.
Stable Terrain Adaptability:
Reinforced triple-grouser track system (600mm width, 45 plates/side) minimizes ground pressure (46.5 kPa) for secure operation on soft or uneven surfaces.
Confined-Site Mobility:
Combines 35° climbing ability with dual travel speeds (5.2 km/h / 3.5 km/h) and a compact transport length (4.85m), enabling agile maneuvering in tight spaces.
