Engine and Performance
- Powered by a YANMAR 4TN98S four-cylinder, water-cooled, direct-injection diesel engine with a displacement of 3.319 liters.
- Rated power output stands at approximately 34.8 kW (46.7 HP) at 2,100 rpm, coupled with a maximum torque of 212 Nm at 1,260 rpm, which enables solid digging and loading capabilities.
- The engine features advanced fuel injection technology combined with an ECO mode that reduces fuel consumption by about 20% compared to standard operation.
- Features a high-efficiency hydraulic system with a combined pump setup: one variable displacement axial piston pump and one pilot gear pump.
- Maximum discharge flow totals approximately 126 L/min for the main hydraulic circuits plus an additional 12.6 L/min for pilot operations.
- Relief valve settings include:
- Boom, arm, and bucket circuit: 29.4 MPa (300 kgf/cm²)
- Travel circuit: 29.4 MPa (300 kgf/cm²)
- Swing circuit: 24.5 MPa (250 kgf/cm²)
- Control circuit: 3.2 MPa (33 kgf/cm²)
- Blade circuit: 26.5 MPa (270 kgf/cm²)
- Boom, arm, and bucket circuit: 29.4 MPa (300 kgf/cm²)
- The hydraulic system supports precise control and powerful lifting operations, reinforced by an 8-spool main control valve.
- Operating weight ranges between approximately 7,010 and 7,240 kg (15,459 to 15,960 lbs), balancing portability with power.
- Shoe widths available from 450 mm to 600 mm provide greater traction choices based on terrain.
- Ground pressure varies from 24.4 kPa to 31.5 kPa, ensuring stable operation on soft soils while offering mobility.
- Bucket capacity around 0.35 cubic meters supports substantial material movement in fewer cycles.
- Swing speed approximately 10.4 RPM facilitates swift rotational movements improving cycle efficiency.
- Travel speeds vary between 2.6 km/h and 4.7 km/h, permitting navigation over urban and construction sites effectively.
- The machine’s gradeability reaches up to 58% (approximately 30° slope), ensuring capability in hilly or uneven terrain.
- Spacious, airtight cab designed for high visibility with ergonomic adjustments including adjustable armrests and suspension seats.
- Low vibration design and rubber-coated foot pedals reduce operator fatigue during long shifts.
- A large touchscreen color monitor simplifies operational visibility, diagnostics, and settings adjustment.
- Convenient ground-level access to engine and hydraulic components eases maintenance routines, minimizing downtime.
- The Kobelco SK80CS supports a wide range of attachments such as buckets, breakers, grapples, and augers, expanding its utility across industries.
- Compact body dimensions enable easy transport on small trucks and maneuverability in tight job site environments.
- The dozer blade width matches crawler dimensions for optimized earth-moving and stability during grading.
- Large rear maintenance space and a right-side mainline panel provide easy access to filters, electrics, and fluid reservoirs.
- A smaller hydraulic oil tank reduces oil change costs without compromising system performance.
- Supported by a robust dealer network ensuring reliable parts supply and expert service in India, Bangladesh, and Nepal among other markets.
- Variable Displacement Axial Piston Pump: Hydraulic pump adjusting fluid flow based on demand improving efficiency.
- Relief Valve: Safety valve limiting maximum hydraulic pressure to protect components.
- Gradeability: Maximum slope percentage that a machine can climb safely.
- Swing Speed: Rotation speed of the excavator house in revolutions per minute.
- ECO Mode: Operational setting prioritizing fuel efficiency over maximum power output.
