Meet the New Kobelco SK850LC-11: Big Power for the Biggest Jobs
The Kobelco SK850LC-11 is a high-performance, large-class excavator engineered to deliver exceptional power, efficiency, and durability for the most demanding applications. Powered by a robust engine producing up to 512 HP (382 kW) and operating at more than 80 metric tons, it offers outstanding digging force, lifting capability, and jobsite productivity
Introducing the Kobelco SK850LC-11
The Kobelco SK850LC-11 is a large conventional excavator designed specifically for demanding applications including heavy civil construction, quarry work and mass excavation.
At the heart of the machine is an Isuzu 6WG1 engine producing 512 horsepower (382 kW) and maximum torque of 1,620 lb-ft (2,200 Nm).
Pair that power with an operating weight between approximately 190,700 and 192,300 pounds, and you’re looking at a machine designed for applications where smaller excavators simply don’t have the size or muscle to maintain the required production.
But Kobelco didn’t build the SK850LC-11 around power alone. The new machine incorporates an advanced hydraulic system designed to minimize energy loss while maintaining strong digging and lifting performance, helping operators balance production with fuel efficiency.
Where Does the SK850LC-11 Fit in the Kobelco Excavator Lineup?
The easiest answer? Right at the top.
The SK850LC-11 is currently the largest conventional excavator in Kobelco’s North American lineup.
Kobelco’s conventional excavator family starts with the SK130LC-11 at approximately 32,800 pounds and progresses through the SK170LC-11, SK210LC-11, SK260LC-11, SK300LC-11, SK350LC-11 and SK520LC-11 before reaching the SK850LC-11.
Here’s how the larger models compare:
| Model | Engine Power | Operating Weight |
|---|---|---|
| SK350LC-11 | 265 hp | 84,200 lb |
| SK520LC-11 | 463 hp | 121,000 lb |
| SK850LC-11 | 512 hp | 190,700-192,300 lb |
The jump between the SK520LC-11 and SK850LC-11 is significant.
The SK850LC-11 adds nearly 70,000 pounds of operating weight and increases engine output from 463 to 512 horsepower. That moves the machine beyond traditional general construction work and into applications where high production and heavy material movement are the priority.
Think major infrastructure projects, quarry production, large earthmoving operations and mass excavation.

512 Horsepower for Heavy-Duty Work
Moving nearly 200,000 pounds of excavator while digging, swinging, lifting and traveling requires serious power.
The SK850LC-11 uses a 512-horsepower Isuzu 6WG1 Tier 4 Final engine, replacing the Hino engine used in the previous SK850LC-10 generation.
The new engine delivers the power and torque necessary for heavy loads and large attachments while working alongside an updated hydraulic system designed to minimize wasted energy.
That combination matters on high-production jobs.
A large excavator isn’t earning money simply because it’s running. It earns money by keeping material moving. Faster loading cycles, strong digging performance and efficient hydraulic response can translate directly into more trucks loaded and more material moved during a shift.
Serious Digging and Lifting Power
The numbers tell the story.
The SK850LC-11 produces up to 90,600 pounds-force of bucket digging force and 69,900 pounds-force of arm crowding force.
That gives operators the breakout capability needed to tackle dense material and demanding excavation while the machine’s substantial operating weight provides the stability required for heavy lifting.
The machine also produces 152,400 pounds-force of drawbar pulling force, helping it maneuver through demanding quarry and heavy construction environments.
Advanced Hydraulics Designed for Productivity
Power is only useful if the machine can put it to the ground efficiently.
The SK850LC-11 uses two main hydraulic pumps and an advanced hydraulic system engineered to minimize energy loss while maximizing usable power.
Kobelco has also incorporated independent travel hydraulics into the machine. This helps maintain smooth attachment operation while traveling, which can be particularly valuable when repositioning the machine while handling material or working on large excavation sites.
The result is a machine designed to respond smoothly to operator inputs while maintaining the hydraulic performance expected from an excavator in this size class.
Built for Quarry and Mass Excavation
The SK850LC-11 isn’t intended to replace the excavator doing everyday utility or commercial construction work.
This machine is built for production.
Ideal applications include:
- Quarry and aggregate operations
- Mass excavation
- Highway and infrastructure projects
- Large-scale site development
- Heavy material handling
- Truck loading
- Deep excavation
- Applications requiring large attachments
For aggregate producers in particular, the combination of digging force, bucket capacity, stability and fast loading cycles can make the SK850LC-11 an important production machine.
Technology Comes Standard
Today’s large excavators aren’t just about horsepower and hydraulics. Equipment data can play an increasingly important role in managing productivity and operating costs.
The SK850LC-11 includes several technologies designed to help owners and operators get more information from the machine.
K-LOAD Onboard Weighing
Kobelco’s K-LOAD system provides onboard weighing capabilities, helping operators monitor payloads during loading operations.
For truck loading and quarry applications, knowing how much material is being moved can help crews improve consistency, reduce overloading and better understand daily production.
KOMEXS Telematics
The SK850LC-11 also features KOMEXS, Kobelco’s telematics system.
KOMEXS provides owners and fleet managers with access to machine information that can assist with equipment monitoring, utilization and maintenance planning.
For a machine of this size, where downtime can have a significant effect on production, better visibility into machine health can be particularly valuable.
A New Cab for the -11 Generation
When an operator spends an entire shift moving hundreds or thousands of tons of material, comfort matters.
The SK850LC-11 features an updated cab designed around operator productivity and comfort. A 10-inch color touchscreen monitor provides access to machine information and settings, while customizable controls allow operators to tailor machine response to their preferences.
Kobelco has also equipped the machine with a three-camera visibility system, helping provide better awareness around a machine with an operating weight approaching 100 tons.
Improved visibility, intuitive controls and a comfortable working environment can help operators stay focused throughout long production shifts.
How Does the SK850LC-11 Compare to the SK520LC-11?
For many contractors looking at Kobelco’s larger excavators, this will be the big question.
The SK520LC-11 remains a powerful large excavator at approximately 121,000 pounds and 463 horsepower. It’s well suited for heavy construction, excavation and demanding lifting applications where a 50-ton-class machine provides the right balance between production and mobility.
The SK850LC-11 takes a major step upward.
At more than 190,000 pounds with 512 horsepower and 90,600 pounds-force of bucket digging force, it’s designed for applications where production requirements justify a much larger machine.
Choosing between them comes down to what you’re moving and how much of it needs to move.
If you’re performing general heavy excavation and need greater flexibility moving between jobs, the SK520LC-11 may be the better fit.
If you’re loading trucks all day in a quarry, completing major mass excavation or tackling large infrastructure work where maximum production is the goal, the SK850LC-11 moves into its element.
Is the Kobelco SK850LC-11 Right for Your Operation?
The SK850LC-11 isn’t a machine every contractor needs.
But for the operations that do need an excavator in this size class, productivity becomes incredibly important.
Quarries, aggregate producers, heavy civil contractors and large site-development companies need machines capable of moving significant amounts of material shift after shift.
That’s where the SK850LC-11 fits.
It brings together a 512-horsepower engine, substantial operating weight, powerful digging forces, advanced hydraulics, onboard weighing, telematics and modern operator technology in a machine designed specifically for high-production work.
