Features
The 31.2‑ton KOBELCO SK310LC‑12 heavy‑duty crawler excavator belongs to 31‑ton class, designed for quarry rock‑digging, large‑volume earth‑moving, road construction and heavy‑loading works. It delivers high production efficiency, outstanding fuel‑economy and reliable structural durability for continuous heavy‑cycle site operations.
Cummins B7 six‑cylinder turbo‑intercooled common‑rail diesel engine outputs 180 kW rated power and 949 N·m maximum low‑speed torque, equipped with DOC+DPF+SCR full exhaust after‑treatment system. Auto‑idle and auto‑idle‑stop functions cut fuel consumption during standby periods, stable power output adapts to various complex construction‑site fuel conditions.
Optimized dual variable‑displacement main‑pump hydraulic system with boom energy‑recovery circuit reduces internal pressure loss. H/S/E three‑power‑mode selection covers heavy rock excavation, standard earthwork and fuel‑saving operation. Boost pressure reaches 37.8 MPa for powerful breakout force, shorter cycle time and smoother compound movements. Optional factory‑installed breaker piping with return‑oil filter supports large‑size hydraulic hammer attachments.
HD‑spec reinforced boom & arm with thickened high‑stress sections improves anti‑impact performance for quarry and stone‑handling conditions. Long‑track LC‑type heavy‑duty undercarriage provides low ground pressure and excellent lifting stability on uneven ground. Multiple track‑guide protectors extend service life of track chains under abrasive working‑conditions.
Spacious ROPS‑FOPS certified sealed operator cabin with silicone‑oil vibration‑dampening mounting. Equipped with air‑suspension operator seat, 10‑inch full‑color multi‑function monitor, 270‑degree surround‑view camera system, automatic air‑conditioning, Bluetooth radio and multi‑LED working lamps to enhance all‑round operation safety.
Grouped ground‑level service points simplify daily inspection, greasing and filter replacement. Suction‑type cooling fan effectively prevents dust clogging in dusty quarry environments. Kobelco telematics system supports remote machine‑status monitoring for predictive maintenance. Global spare‑parts network keeps operating costs low and maintains solid residual value for rental fleets.
Multiple optional attachments: hydraulic quick coupler, heavy rock breaker, rock bucket, reinforced heavy‑duty mining track shoes for diversified heavy‑condition adaptation.
