Of course we wanted machines with greater digging capacity. But they also had to be fuel-efficient and economical, while imposing less of a burden on the local and global environments. Applying our advanced technologies, we developed KOBELCO's new ACERA GEOSPEC series, an entirely new kind of excavator that beautifully balances all the demands of today's construction industry. Lean and efficient with capacity to spare, these sleek powerhouses bring a whole new style to the worksite while setting new standards for environmental responsibility. ACERA GEOSPEC The “GEO” in GEOSPEC expresses our deep respect for our planet, and for the solid ground where excavators are in their element. This is accompanied by SPEC, which refers to the performance specifications needed to get the job done efficiently as we carry on the tradition of the urban-friendly ACERA series. 1 2 Performance The GEOSPEC Difference: NEXT-3E Technology Next-Generation Electronic Engine Control Efficient Performance!

ITCS (Intelligent Total Control System) is an advanced, computerized system that provides comprehensive control of all machine functions. 4 Reliability, Durability, Environmental Responsibility The GEOSPEC Difference: The Value and Quality of Sturdy Construction! Stable Attachment Strength The GEOSPEC Difference: Designed for the Environment and the Future! Emergency Acceleration (Dial) Permits Continued Operation in the Unlikely Event of Malfunction Forged and cast steel components are used throughout. The standard arm and boom also meet specifications that were classified as “reinforced” on previous KOBELCO models to ensure reliable strength. If unexpected trouble is experienced with the ITCS mechatronic control system, the machine can still be operated using the emergency acceleration system. Digging modes are also automatically relayed to an emergency system so that digging can continue temporarily until a service person arrives to repair the primary system. Pre-air Cleaner (optional) The optional pre-air cleaner prolongs a replacement cycle of main air cleaner. Auto Idle Stop Provided as Standard Equipment Integrated cast steel boom top HD boom Engine throttle Mechatronic controller Engine Pump Emergency acceleration Newly designed MCU ● Vertical alignment and sealed cover gives better protection from water and dust ● Integration in base plate boosts assembly quality ● Reliable fixture to base plate Forged steel arm foot boss Cast steel boom foot boss HD arm New MCU Conventional MCU Countermeasures Against Electrical System Failure All elements of the electrical system, including controller, have been designed for enhanced reliability. This function saves fuel and cuts emissions by shutting down the engine automatically when the machine is on stand by. It also stops the hourmeter, which helps to retain the machine’s asset value. Automatic Acceleration/Deceleration Function Reduces Engine Speed Engine speed is automatically reduced when the control lever is placed in neutral, effectively saving fuel and reducing noise and exhaust emissions. The engine quickly returns to full speed when the lever is moved out of neutral.

Of course we wanted machines that would sell well, but we didn’t want to emphasize one aspect of performance at the expense of other features. So, instead of narrowly focusing on fuel-efficient, economical operation, for example, or on environmental compatibility, or on any other particular feature, we sought to develop well-rounded machines that can balance seemingly contradictory demands. Now, we're proud to introduce the latest member of the ACERA GEOSPEC family— the 80-ton SK850LC. This machine has it all: the highest productivity in its class; a resilient power plant; outstanding durability proven in the field in large building demolition machines; easy transportability; and an environmentally responsible design that reduces fuel consumption and operating costs. In short, the SK850LC satisfies all of the tough conditions that must be met by a large excavator engaged in demanding, continuous operations. So welcome to the birth of a new standard of performance: the 80-ton ACERA GEOSPEC SK850LC. With its efficient, sleek design, it brings a whole new excavating style to the worksite that's tuned to the natural beauty of our world. 1 Pursuing the “Three E’s” The Perfection of Next-Generation, Network Performance Enhancement Greater Performance Capacity ●New hydraulic circuitry minimizes pressure loss ●High-efficiency, electronically controlled Common Rail Fuel Injection Engine ●Powerful travel and arm/bucket digging force ●High-power engine and high swing torque Economy Improved Cost Efficiency ●Advanced power plant that reduces fuel consumption ●Easy maintenance that reduces upkeep costs ●Maintenance walk ensures easy access and maintenance ● High structural durability and reliability that retain machine value longer Environment Features That Go Easy on the Earth ●Auto Idle Stop as standard equipment ●Noise reduction measures (with improvement of the sound quality) minimize noise and vibration ACERA GEOSPEC The "GEO" in GEOSPEC expresses our deep respect for our planet, and for the solid ground where excavators are in their element. This is accompanied by SPEC, which refers to the performance specifications needed to get the job done efficiently as we carry on the tradition of the urban-friendly ACERA series. 2 The GEOSPEC Difference: Efficient Performance! Great Productivity and Low Fuel Costs Advanced hydraulic technology keeps fuel costs low matches pump output with a high efficiency engine that conserves fuel, resulting in great productivity and low fuel costs. High Swing Torque The use of high swing torque delivers a smoother, stronger and swing for faster, more efficient cycle times. It also provides plenty of start-up swing power for safe operation on slopes. Swing torque: Swing speed: 268 kN m 8.4 min-1 • Plenty of Digging Force Digging is smoother than ever with the newly shaped bucket. New bucket Previous bucket The sharp edge penetrates more easily. Max. bucket digging force: Max. arm crowding force: 3 403 kN {41.1 tf} 311 kN {31.7 tf} Strongest Travel Power and Drawbar Pulling Force in Its Class! The large-capacity motor delivers the strongest travel power and drawbar pulling force in the machine's class, making it ideal for large civil engineering projects, rock-crushing work, and other power-intensive applications. Travel speed: Drawbar pulling force: 4.2/2.7 km/h 637 kN {65.0 tf} Excellent Lateral Stability The SK850LC has the widest crawlers in its class for outstanding lateral stability. Fitted with a 5.4 m3 bucket, it can safely lift a maximum of 9.92 tons over the side, the most in its class. (Condition: rating over side, 10.7 m reach at G. L., 900 mm shoe) “Top-class” lifting capacity 9.92t in its class Widest crawlers in its class Performance 2 Extended Continuous Operation (Large-Capacity Fuel Tank) The large-capacity fuel tank, combined with higher fuel efficiency, enables the SK850LC to operate continuously for twelve hours. Fuel tank: 960L NEXT-3E Technology Next-Generation Electronic Engine Control The high-pressure, common-rail fuel-injection engine features adjustable control to maximize fuel efficiency and provide powerful medium/low-speed torque. The result is a highly fuel-efficient engine. * Continuous digging in S mode. Length of continuous operation will vary with type of operation and load on engine. New Cooling System The patented Maintenance Walk as air duct is another KOBELCO innovation that further enhances the cooling system's effectiveness. Oil cooler Air Intercooler Maintenance Walk (air duct) Air intake Radiator The cooling fan changes speed automatically according to the temperature of the cooling water in the radiator. This prevents overheating when the water temperature rises, allowing continuous, high-load operation. When the water temperature falls, the cooling system operates very quietly, contributing to both low noise and low fuel consumption. Engine Light-Touch Levers The operating levers are light and easy to move, reducing operator fatigue over long hours of operation. Seamless, Smooth Combined Operations The GEOSPEC machines have inherited the various systems that make inching and combined operations easy and accurate, with further refinements that make a good thing even better. Leveling and other combined operations can be carried out with graceful ease. 3 NEXT-3E Technology Total Tuning Through Advanced ITCS Control The next-generation engine control is governed by a new version of ITCS, which responds quickly to sudden changes in hydraulic load to ensure that the engine runs as efficiently as possible with a minimum of wasted output. ITCS (Intelligent Total Control System) is an advanced, computerized system that provides comprehensive control of all machine functions. Simple Select: Two Digging Modes H-Mode: For heavy duty when a higher performance level is required. S-Mode: For normal operations with lower fuel consumption. Two additional modes for specialized applications: ●The arm cylinder heads are arrang- ed in a double row to reduce pressure loss in the return line and enhance fuel efficiency. The double row also enables faster arm retraction for better productivity. ●Electronic active control system ●Arm regeneration system ●Boom lowering regeneration system ●Variable swing priority system ●Swing rebound prevention system 1 Arm extension Double-row head cylinders NEXT-3E Technology New Hydraulic System Rigorous inspections for pressure loss are performed on all components of the hydraulic piping, from the first spool of the control valve to the connectors. This regimen, combined with the use of a new, high-efficiency pump, cuts energy loss to a minimum. Attachment Mode Selector Switch (Optional) There's a choice of three different hydraulic circuits, to accommodate bucket, crusher or breaker, and the desired attachment mode can be selected with a switch, which automatically configures the selector valve. All attachment modes can be used in either Smode or H-mode. Dump Counter Is Available Using the dump counter switch, which operates in tandem with the motor, the operator can display on the monitor and record the number of dumps made. 4 The GEOSPEC Difference: The Value and Quality of Sturdy Construction! Large excavators are often used on steep, rough roads in mountains and quarries where they are expected to operate continuously for many hours at a time. They have to be durable. The high-strength construction of the SK850LC has already been proven through use in large KOBELCO building demolition machines, and has been carefully scrutinized through 30,000 hours of additional durability testing. It has the tough durability required in all of its components, including the upper and lower body and attachment. Stable Attachment Strength All components are either cast or forged, with HD type boom and arm provided as standard equipment. The balanced design ensures excellent durability even when using a large bucket, providing highly reliable attachment strength. •Arm HD arm (standard) Cast arm foot boss High-strength lock guard Upper Frame with High Structural Strength FEM* analysis was used determine the best materials, select the steel plate, and create a high-strength design to resulting in an upper frame that features high structural strength. *FEM (Finite Element Method) Method of numerical analysis used in structural mechanics Strong Carbody Structure •Bucket Front-edge angle and "R" shape optimize digging performance •Boom HD boom (standard) Cast boom foot boss (Self-lubricant bush with high lubricating ability) Large Components Used in the Crawler Frame New shape Previous model Strength is especially crucial in the carbody. The swing mechanism on the SK850LC is mounted without a column, thereby increasing the carbody's crosssection size for greater strength. 5 •Reinforced Travel Reduction Gear Cover •Track Guides Installed in Three Places A high-strength protective cover enhances the durability of the travel reduction gear. Track guides installed in three different places improve travel stability and help prevent the crawlers from coming off the rollers. More track guides can be installed as an option. Reliability, Durability, Environmental Responsibility Emergency Acceleration (Dial) Permits Continued Operation in the Unlikely Event of Malfunction If the mechatronic system should happen to malfunction, the ECU will automatically put the engine into high idle (maximum RPM), allowing the operator to continue working until a service specialist can come to repair the machine. During emergency operation, the hydraulic pumps automatically sense any trouble and control hydraulic flow accordingly. •Reinforcement Rib FEM analysis was used to add reinforcement ribs in strategic locations where the boom cylinder is attached to help prevent cylinder damage. Engine throttle Mechatronic controller Engine Pump Normal Emergency ENGINE ECU •Easily detachable bolt-on type Undercover for upper carriage Newly designed MCU ● Vertical alignment and sealed cover gives better protection from water and dust ● Integration in base plate boosts assembly quality ● Reliable fixture to base plate New MCU Conventional MCU Countermeasures Against Electrical System Failure All elements of the electrical system, including controller, have been designed for enhanced reliability. Excellent Transportability Counterweight Device The counterweight device operates both vertically and horizontally for safe and efficient onsite assembly and disassembly. Four Disassembly and Transport Patterns The SK850LC can be disassembled and transported in four different ways, including: no counterweight, with boom attached; main body only; main body without crawler frame; etc. Variable Gauge Crawler The variable gauge crawler extends the crawlers to a maximum width of 4,300 mm (with 750 mm shoes) for extremely stable operation, and retracts them to a compact minimum width of 3,500 mm for easier transport. 6 The GEOSPEC Difference: Easy Maintenance That Supports Large-Scale Operation! Daily maintenance checks are essential for the successful operation of large, continuously operating excavators. Inspections and maintenance must be quick and easy to maximize productivity. With its maintenance walk, the SK850LC provides easy access to essential components and systems so that more time is spent on the job. Handrails on top of upper frame and top of counterweight are customized equipment. (Available for Japanese market only) Maintenance Walk Serves as an Air Duct During Operation Kobelco's unique design covers the maintenance walk to create an air duct that helps to keep the radiator cool during machine operation. 7 Easy Inspection of Swing Bearing, Gear and Bolt A small access port is located in front of the upper frame to make it easier to inspect the swing bearing, gear and bolt.
