Detailed Description & Applications

The Used Kobelco SK300 Excavator is a mid‑to‑large class hydraulic excavator engineered for demanding earthmoving, groundwork and quarry operations. Built in 2019 and equipped with the Hino J08 EVV‑KSDP engine delivering 268 hp, this machine blends durable power with proven Kobelco hydraulic systems to provide dependable cycle times and consistent torque for heavy digging tasks.

Core strengths

1. Robust performance: 30‑ton operating weight and a 1.2 m³ bucket enable efficient trenching, bulk excavation and loading operations.

2. High breakout force: 174 kN tear‑out force offers strong material penetration across compacted soils and mixed rock.

3. Proven powertrain: Hino six‑cylinder engine with 1017 Nm peak torque for sustained productivity under load.

4. Versatile reach: 11.72 m maximum horizontal reach and 8.1 m digging depth make the unit suitable for utilities, pipeline, and civil projects.

5. Field‑serviceable components: Common service points and durable undercarriage options facilitate lower lifecycle maintenance costs.

Design and operation highlights

The SK300 features a long‑carriage undercarriage (LC) with 600 mm track shoes that balance ground pressure and stability. The machine’s hydraulic circuits are tuned for a responsive operator experience, allowing precise bucket control during grading and finishing. The standard 1.2 m³ bucket is sized for general excavation and loading; optional attachments and varied bucket widths can be fitted to match site requirements.

Typical applications

1. Heavy civil construction: foundation excavation, road subbase preparation and bridge abutment works.

2. Quarry and aggregate handling: loading haul trucks and feed hoppers with consistent bucket fills.

3. Pipeline and utility trenches: long reach and stable digging characteristics for deep trenching.

4. Demolition support: when fitted with breakers and grapples for selective demolition and material sorting.

5. General earthworks for contractors requiring a reliable used machine with known specifications.

Benefits for buyers and fleet managers

Purchasing a Used Kobelco SK300 Excavator provides balanced value through lower acquisition cost while retaining the performance envelope of a modern mid‑sized excavator. Fleet managers will appreciate the machine’s compatibility with common maintenance practices, available spare parts, and its adaptability to a wide range of attachments. The origin in Shanghai combined with rapid delivery (15–20 days) and high supply capacity makes this an attractive option for projects with tight schedules.

What to inspect before purchase

1. Undercarriage wear condition: track tension, sprocket teeth and track shoe wear.

2. Hydraulic system: check hoses, cylinders and boom swing for leaks or abnormal play.

3. Engine health: service records, oil analysis if available, and turbo/charge system condition.

4. Structural integrity: boom, arm and chassis for signs of repair or fatigue.

5. Electrical and control systems: gauge function, safety switches and monitoring systems.

Conclusion

The Used Kobelco SK300 Excavator represents a pragmatic choice for contractors and equipment rental operators seeking a reliable 30‑ton class machine with strong digging performance and efficient operating characteristics. Retaining original Kobelco hydraulic design and a durable Hino power unit, it is well suited for heavy excavation, roadworks and quarry roles where uptime and predictable productivity matter. For procurement, the unit is available from Shanghai with a typical 15–20 day delivery window and significant monthly supply capability.
