Product Description
Engineered for demanding excavation applications, this 21-ton hydraulic excavator delivers robust performance through precision-matched components. The Mitsubishi 6D34-TL engine generates 114 kW at 2050 rpm, paired with a dual-pump hydraulic system supplying 2 x 210 l/min for responsive control across all functions. Operating weight of 20,900 kg provides stability while maintaining 45 Kpa ground pressure for reduced surface impact.
Hydraulic circuits operate at optimized pressures: 34.3 Mpa for main and travel functions, 25.5 Mpa for rotation, ensuring efficient power distribution. The 0.93 m³ backhoe bucket delivers 138 kN digging force, reaching 9,885 mm maximum radius and 6,630 mm depth. Water-cooled operation maintains consistent performance in extended duty cycles.
Key specifications include:
- Compact transport dimensions: 9,397 mm length, 2,980 mm width
- 12.5 rpm rotation speed with 2,750 mm rear turning radius
- Dual travel speeds: 3.2/5.5 km/h for versatility
- 70% (35°) grading capability on challenging terrain
Currently located in Linyi, Shandong, this Kunshan-manufactured unit represents proven Chinese engineering standards from the SY215C-8 series.
