KOBELCO Construction Machinery has announced the launch of the new SK350LC-11 excavator, adding to its portfolio of construction machines. The new Kobelco SK350LC-11 features a 265-hp Isuzu Tier 4 Final engine to support lifting heavy loads and operating large tools. With redesigned boom cylinders, the SK350-11 has the power to handle trench boxes.
With the press of a switch, the machine dedicates one hydraulic pump to the travel system and one to all the other functions on a continuous basis. This allows the 11-series Kobelco machines to travel while having the ability lift and swing heavy loads. The SK350LC-11 has three working modes: Eco, S and H mode for balancing between high performance, economy and fuel consumption. Heavy Lift and Power Boost add power needed to get through tough conditions. The in-cab hydraulic pressure release function allows customers to change work tools or hoses safely. The machine’s 84,200-lb. operating weight provides stability in reach and lift situations. The machine’s side panels are thick, while the increased diameter of the bucket cylinder pin contributes to durability for using various work tools.
The cabin includes a seven-way adjustable, heated air suspension seat that moves together with the armrests and hydraulic controls. The operator’s pilot levers move horizontally, while also providing shorter lever strokes to deliver movement. Multiple air conditioning and heater vents are directed towards the operator. On the right console, there is a jog dial that integrates multiple functions into a single user interface with a large 10-in. color monitor. This menu screen displays operating data 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 also now fully adjustable by the operator through the monitor. Mode settings for other attachments, such as a tilt rotator, can also be added or changed to customize the operator’s experience. In addition, all internal switches and dials in the cabin have LED backlighting. The cabin is equipped with FM-AM radio, AUX, Bluetooth, hands-free telephone radio, smartphone holder, USB charger and a 12V power outlet.
A newly structured hydraulic oil filter prevents foreign matter from entering the oil tank during maintenance. All filters are accessible from ground level.
For safety, a heavy-duty Level II overhead top guard is standard and can be tilted open for cleaning the top window. Additionally, rear swing flashers and rear work lights are integrated into the counterweight for added safety and visibility on busy jobsites. Seven LED lights (two on the boom, two on the top front of the cab, one on the right-side body and two facing rear on the counterweight) are also now standard to provide visibility in low-light conditions.
Other items like one- and two-way hydraulics (nibbler-breaker), rock guard and 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 mounting brackets for system installation without the need to weld and paint. These brackets are designed to fit multiple brands for both 2D and 3D systems.
Monitoring the SK350LC-11’s work status remotely is possible with the KOMEXS (KOBELCO Monitoring Excavator System). The machine’s operational information, such as hours, fuel consumption and maintenance status, can be obtained remotely. For security, an engine start alarm, e-fence and current or past location history are also included.
