KOBELCO Construction Machinery USA has introduced the SK850LC‑11, the newest and largest model in its next‑generation excavator lineup.
The 85‑ton machine is designed for high‑capacity earth-moving, mass excavation, and other heavy production environments where power, stability, and fuel efficiency directly influence jobsite output. According to the company, the SK850LC‑11 weighs in at roughly 186,000 pounds and is powered by a 512‑hp Isuzu Tier IV Final engine that delivers the torque needed to handle large tools, heavy lifts, and continuous truck loading cycles.
The updated hydraulic system is engineered to balance efficiency with breakout performance. KOBELCO’s pilot‑controlled hydraulics provide smooth response and strong digging forces—90,598 lbf (pound force) at the bucket and 61,148 lbf at the arm—while features such as boom‑to‑arm regeneration, ECO‑Mode, auto idle stop, and auto engine deceleration help reduce fuel burn.
The machine’s Independent Travel function dedicates one hydraulic pump to travel and one to implement operation, allowing operators to lift, swing, and carry loads while tracking without the slowdown common in competing machines.
Heavy Lift and unlimited‑use Power Boost modes are available for demanding conditions, and an in‑cab hydraulic pressure release system simplifies tool and hose changes.
Durability updates include a retractable undercarriage, three track guides, belly guards, a swivel guard, and folding catwalks. Cooling performance is supported by a reversible fan and removable clean‑out screens.
Standard lighting includes six front and four rear LED work lights, and the machine is equipped with rear swing flashers, a battery disconnect switch, and a heavy‑duty Level II FOPS cab guard that opens for cleaning.
Inside the cab, KOBELCO has focused on operator comfort and control. The -11 series platform features expanded space, improved visibility, and a heated air‑suspension seat with integrated armrests and controls. Pilot levers move horizontally to reduce wrist strain, and shorter lever strokes support more precise movements.
Multiple HVAC vents target the operator area, while a jog dial and 10‑inch color monitor centralize machine settings, attachment modes, maintenance intervals, fuel data, and a 270‑degree camera view. Hydraulic flow rates for breakers, nibblers, and rotating grapples can be adjusted through the monitor, and operators can store custom attachment profiles.
LED‑backlit switches improve visibility in low‑light conditions, and the cab includes Bluetooth audio, hands‑free calling, USB charging, and a 12V outlet.
Standard technology includes the KOMEXS telematics platform, the K‑LOAD weighing system, and a four‑year/4,000‑hour limited full‑machine warranty. Optional equipment includes a front cab guard and a removable counterweight. KOBELCO notes that the SK850LC‑11 continues the company’s long‑standing focus on quality, innovation, and performance since it began building excavators in 1930.
