Features
The 39.4‑ton KOBELCO SK390LC‑12 heavy‑duty crawler excavator is built for quarry operations, rock excavation, large‑volume earth‑moving and heavy‑loading projects. It combines high‑output digging performance, enhanced structural rigidity and excellent fuel efficiency for continuous heavy‑cycle site operations.
Original Isuzu 6HK1 six‑cylinder turbo‑intercooled common‑rail diesel engine delivers 210 kW rated power and 1080 N·m low‑speed torque, torque increased by 8 % versus prior generation. Matched with DPF exhaust after‑treatment, it offers reliable output under high‑load conditions; auto‑idle and auto‑idle‑stop functions effectively cut fuel consumption during standby periods.
Dual variable‑displacement main‑pump hydraulic system with 37.8 MPa boost‑pressure function generates powerful bucket breakout force. H/S/E three‑power modes cover heavy rock excavation, standard earth‑work and fuel‑saving operation. Smooth responsive compound movements shorten digging cycle times and improve overall productivity. Optional factory breaker piping supports large‑size hydraulic hammer attachments.
Extra‑reinforced SHD‑spec boom & arm with thickened high‑stress sections improves impact‑resistance for quarry and rock‑handling applications. Long‑contact LC‑type heavy‑duty undercarriage provides outstanding lifting stability and low ground pressure on uneven rough terrain; durable track components extend service‑life under abrasive working‑conditions.
Spacious ROPS‑FOPS certified sealed cabin adopts silicone‑oil vibration‑dampening mounting. Equipped with air‑suspension operator seat, 10‑inch full‑color multi‑function monitor, automatic air‑conditioning, Bluetooth radio and multi‑LED working lamps for enhanced all‑round visibility during day‑and‑night shifts.
Grouped ground‑level service access simplifies daily inspection, greasing and filter‑replacement. Suction‑type cooling fan effectively resists dust clogging in dusty quarry environments. Kobelco telematics system enables remote machine‑status monitoring for predictive maintenance. Global spare‑parts resources control operating costs and preserve solid residual value for rental & mining fleets.
Multiple optional attachments: hydraulic quick coupler, heavy rock breaker, rock bucket, reinforced heavy‑duty track shoes for diversified heavy‑condition adaptation.
