Features
The 3.16‑ton KOBELCO SK28SR‑7 zero‑tail mini excavator features 0‑mm rear overhang together with retractable undercarriage. Track width can be narrowed for passing narrow doorways and confined‑space access, widely used for backyard works, pipeline trenching, greenhouse maintenance and light indoor demolition.
YANMAR 3TNV88 three‑cylinder water‑cooled direct‑injection engine delivers 87.8 N·m peak torque, available in Tier3 / Stage‑V emission versions. Matched with KOBELCO iNDr low‑noise dust‑proof cooling system, it keeps stable output under high‑temperature conditions and lowers noise interference in residential zones.
Integrated‑flow multi‑pump hydraulic system brings improved bucket breakout force, realizes smooth and responsive compound movements even under partial heavy‑load. ECO mode plus auto‑idle function effectively cuts fuel consumption for long‑hour light cyclic jobs.
Side‑swing boom enables tight digging alongside walls without blind zones. Standard 1.18 m stick and optional 1.48 m long stick expand digging depth and horizontal reach. Factory‑installed auxiliary hydraulic lines support breakers, augers and grapples for quick attachment replacement.
Rubber track shoes protect lawns, asphalt and paved surfaces from scratches. ROPS‑FOPS certified reinforced structure enhances operator safety. Color LCD monitor displays real‑time machine data. Ground‑level service points simplify daily inspections; global spare‑parts network maintains good residual value for rental fleets.
