Kobelco launches next-generation SK350lC-11 excavator with new cab, new engine with increased lifting and productivity.

This next generation -11 machine delivers superior performance, greater efficiency, and more productivity by following the Kobelco Performance By Design like the other new -11 series machines. 

The 30–35 ton class machines are the main workhorse on most large job sites, the new Kobelco SK350LC-11 takes charge with industry leading lifting power, superior swing and drawbar torque to get the big jobs done. The new 265 horsepower Isuzu Tier 4 Final engine has the power and torque to lift heavy loads and operate large tools with ease all day long. It offers a combination of boom-to-arm regeneration and swing-priority hydraulics and will outperform most competitive models so users can load more trucks and move more material at the end of the day. With the redesigned larger boom cylinders, the SK350-11 has the power to lift trench boxes and heavy loads around the job site like never before. 

Having the ability to multifunction while travelling (lift, swing and carry) is one thing that Kobelco does better than others due to the Independent Travel function.  With the press of a switch, the machine dedicates one hydraulic pump to the travel system and one to all  other functions on a continuous basis. This allows the -11 series Kobelco machines to smoothly travel while having the ability lift and swing heavy loads where most of the competitive models cannot. 

The SK350LC-11 has three work modes: Eco, S, and H mode for balancing between high performance, economy, and low fuel consumption. Heavy Lift and Power Boost with unlimited time use add the power needed to get through the toughest conditions. The in-cab hydraulic pressure release function allows customers to change work tools or hoses easily and safely.

The machine’s 84,200-pound operating weight is well balanced to provide excellent stability in reach and lift situations.  Many of its major components have been redesigned for improved durability and performance. For example, the machine’s side panels have been made thicker to enhance body rigidity, while the increased diameter of the bucket cylinder pin contributes to enhanced durability for using various work tools.  

The new -7 Short Radius and -11 Conventional tail swing machines have new cabin environments with enhanced ergonomics and safety features with best-in-class cabin space and visibility.  This new cabin includes a seven-way adjustable, heated air suspension seat that moves together with the armrests and hydraulic controls to reduce operator fatigue, provide excellent shock absorption and superior ride comfort.

The operator’s pilot levers move horizontally without arching the wrist, while also providing shorter lever strokes to deliver a swifter, more precise movement. Air conditioning and heater vents are directed toward the operator to maximize comfort. On the right-side console there is a jog dial that integrates multiple functions into a single user interface with the 10-inch color monitor. This easy-to-operate menu screen facilitates reading of important information including work mode, maintenance intervals and fuel consumption, as well as providing a 270-degree view from the machine’s standard three-camera system.

The hydraulic flow-rate modes of the breaker, nibbler and rotating grapple are now fully adjustable by the operator through the monitor, and the mode settings for other attachments, such as a tilt rotator, can be easily added or changed to customize the operator’s experience. 

All internal switches and dials in the cabin have LED backlighting to provide a bright, clear view in the dark.  The cabin is also equipped with a FM/AM, AUX, Bluetooth, hands-free telephone radio, smartphone holder, USB charger, and a 12V power outlet. 

A standard radiator clean-out screen prevents larger material from clogging the radiator cooling fins and can be easily removed for cleaning. A newly structured hydraulic oil filter prevents foreign matter from entering the oil tank during maintenance, and all filters are easy to access from ground level. 

A heavy-duty Level II overhead top guard is standard and can be tilted open for easy top window cleaning. Rear swing flashers and rear work lights, a Kobelco USA exclusive, are integrated into the counterweight for added safety and visibility on busy job sites. LED lights (two on boom, two on top front of the cab, one on right side body, and two facing rear on the counterweight) are also now standard to provide additional visibility in low light conditions. 

One- and two-way hydraulics (nibbler/breaker), rock guard, replaceable arm bushings, side bumpers, lower swivel guard, control pattern changer (ISO/BHL) and single pedal travel are all standard.  For those needing machine guidance options, the SK350LC-11 comes with preinstalled mounting brackets for easier system installation.  These brackets are designed to easily adapt to fit multiple brands of 2D and 3D systems. 

The unit uses Kobelco’s Monitoring Excavator System (KOMEXS) that remotely monitors operational information, such as hours, fuel consumption and maintenance status.  For added convenience and security, an engine start alarm, e-fence, and current/past location history are also included – ideal for operators of large fleets and multiple locations. It has a standard four-year/4,000-hour full machine warranty with KOMEXS included while covered by factory warranty. Additional extended warranty coverage terms are available.
