Product Description
Engineered with precision in Japan, this 46-ton hydraulic excavator delivers exceptional performance through advanced Kobelco technology. Powered by a robust HINO P11C engine generating 257 kW at 1850 rpm, this machine combines a 10.52L displacement with water-cooled turbocharged efficiency and built-in intercooling for sustained productivity in demanding applications.
Hydraulic superiority defines the SK460-8 series. Dual variable displacement axial piston pumps supply 740 L/min total flow at 34.3 MPa, driving 267 kN bucket digging force and 203 kN arm force. The sophisticated dual-circuit system—31.4 MPa working pressure, 34.3 MPa travel circuit, 25 MPa swing circuit—ensures precise control across all functions.
Key specifications include:
- Operating weight: 46,400–48,300 kg with 1.9 m³ bucket capacity
- Reach capabilities: 12,070 mm maximum digging radius, 7,810 mm digging depth
- 7,000 mm boom and 3,450 mm arm configuration for versatile operation
- Two-speed plunger travel motors with 5.4/3.4 km/h speeds
- 650L fuel capacity for extended runtime
Currently located in Kunming, Yunnan, this joint-venture manufactured excavator represents proven Kobelco reliabil
