Large Excavator SK850LC-10

The Kobelco SK850LC-10 excavator combines higher efficiency and low fuel consumption with 380 kW engine power, a 2.3 - 5.1 m3 bucket capacity and variable-width crawlers.

Higher efficiency, low fuel consumption

Overview

Hydraulic technology delivers increased digging power, productivity and low fuel consumption for demanding worksites, from urban centres to mines.
Improved hydraulic line layouts, larger and smoother piping, low-resistance connections and reduced valve resistance minimise energy loss.
Arm interflow system reduces in-line resistance and pressure loss.

Engine and fuel efficiency

ECO-mode balances productivity and fuel efficiency for urban engineering projects; S-mode provides minimum fuel consumption for utility and precision work; H-mode provides maximum power and productivity.
AIS (Auto Idle Stop) automatically stops the engine when the boarding/disembarking lever remains raised, reducing standby fuel consumption and CO2 emissions.
Variable-geometry turbocharger adjusts air intake to maximise combustion efficiency and reduce PM and fuel consumption.
Water-cooled EGR lowers combustion temperature to reduce NOx.
SCR system with DEF/Urea converts NOx into nitrogen and water; post-exhaust treatment captures and disposes of PM.
Electronic-control common-rail engine uses high-pressure, multiple fuel injection, an EGR cooler and DP filter to optimise combustion and reduce PM and NOx.
Hydraulic engine-cooling fan drive optimises rotation speed to reduce fuel consumption and noise. Independent oil cooler fan matches cooling to hydraulic oil temperature.

Analogue fuel and engine-water-temperature gauges, low-fuel-consumption indicator, digging mode switch and monitor display switch.
Two hand levers or two foot pedals independently control each track forwards and backwards.
All-weather, sound-suppressed steel cab with sealed, pressurised construction to keep dust out and reduce noise.
Coil springs and silicone-oil-filled high suspension mounts reduce vibration; mount stroke is twice that of a conventional mount.
Large front glass and no centre pillar on the right side provide an unobstructed view.
Expanded cab, large door and additional headroom ease entry and exit.
Air-suspension seat, flat-reclining backrest and double-slide adjustment.

Durability and maintenance

Enhanced hydraulic system design improves strength, performance, reliability and durability while reducing downtime.
Hydraulic filter restriction indicator monitors inlet/outlet pressure difference and displays a clogging warning.
Super-fine hydraulic fluid filter separates small particles; protective cover reduces contamination during filter changes.
Self-lubricating attachment-pin bushings and abrasion-resistant bucket-pin bushings. Separately replaceable two-piece bucket bushings protect the arm from bucket-ear contact and wear.
Three heavy-duty track guides on each crawler side frame.
Optional protective lower undercover shields hydraulic piping and equipment from flying rocks, rebar and debris. Optional full track guides resist vibration and reduce de-tracking concerns.
Right-side door and catwalk ease grease refilling; front-deck access door permits ground-level access to the auto grease gun.
Auto-coil grease gun holder, grease tank and lubrication hose.
Bolted double service doors provide access to the intercooler, A/C condenser, fuel cooler, radiator and oil cooler.
Engine compartment includes engine oil drain valve, engine oil filter, fuel pre-filter with water separator, air cleaner and fuel filter.
Three hydraulic oil filters, suction filter, drain filter, large tool box, battery, refuelling pump and battery disconnect switch.
Catwalk, rear swing flashers and maintenance walk improve service access; front upper-frame access port simplifies swing-bearing, gear and bolt inspection.
DEF/AdBlue tank is inside the standard machine storage compartment.
DPF manual regeneration switch, easy-access fuse box, removable two-piece floor mat with handles and tool-free removable inside/outside air-conditioner filters.

Remote monitoring

GEOSCAN uses satellite and cellular communications for remote machine monitoring and routine maintenance management.
Location, workload, maintenance information and diagnostic data are available 24/7.
Records operating hours, fuel consumption, idling time and working-hour categories including digging, idling, travelling and hydraulic attachment use.
Maintenance status can be monitored across multiple machines and sites, with data relayed for servicing planning.
Area alarm notifies when the machine leaves a predefined area; engine-start alarm notifies when it starts outside predefined hours.

Lifting and application requirements

Lift capacities comply with ISO 10567 and do not exceed 87% of hydraulic lift capacity or 75% of tipping load. Asterisk-marked capacities are hydraulically limited.
Arm top pin is the lift point. Ratings apply without a bucket, on level, firm, uniform ground; accessory weights must be deducted.
Lift ratings cover front and side or 360-degree lifting. Allowances are required for ground conditions, side loads, sudden stopping and other operating conditions.
Specialist equipment is required for demolition work.
