Blend of Power, Versatility — SK850LC-11 Hydraulic System

The highly efficient yet powerful hydraulic system minimizes fuel consumption while maximizing power. according to the company.

"The KOBELCO pilot controlled hydraulic system delivers smooth response to operator input with an outstanding digging force of 90,598 lbf and an arm force of 61,148 lbf," said KOBELCO.

It features auto warm-up, combination rotation with two-way nibbler breaker with case drain, ISO/BHL pattern changer and boom and arm safety valves. Having the ability to multifunction while travelling (lift, swing and carry) is provided due to the exclusive "Independent Travel" function. With the press of a switch, the machine dedicates one hydraulic pump to the travel system and one to all the other functions. This allows the -11 series to smoothly travel while having the ability lift and swing heavy loads. Heavy Lift and Power Boost (with unlimited time use) selection adds the power needed to get through the toughest conditions and the in-cab hydraulic pressure release function allows customers to change work tools or hoses easily and safely, according to KOBELCO.

Durability, Maintenance

A heavy-duty exterior includes a retractable undercarriage, three track guides, belly guards, swivel guard and folding cat walks. For added safety, the machine has six front and four rear LED work lights, exclusive rear swing flashers, battery disconnect switch and a heavy-duty Level II FOPS cab guard that opens for easy cleaning. Additionally, the powerful reversable fan and removable clean out screens keep the machine running cool, the company said.

Commitment to Safety, Comfort, Technological Innovations

The -11 series features cabin environments with enhanced ergonomics and safety features with best-in-class cabin space and visibility. This cabin includes a seven-way adjustable, heated air suspension seat that moves together with the armrests and hydraulic controls to reduce operator fatigue, provides excellent shock absorption and superior ride comfort, according to KOBELCO.

The operator's pilot levers move horizontally without arching of the wrist, while also providing shorter lever strokes to deliver a swifter, more precise movement, added KOBELCO. Multiple 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 large 10-in. 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 also are now fully adjustable by the operator through the monitor, and the mode settings for other attachments, such as a hammer, also can be easily added or changed to customize the operator's experience, according to KOBELCO. In addition, all internal switches and dials in the cabin have LED backlighting to provide a bright, clear view in the dark. The cabin is equipped with an FM/AM, AUX, Bluetooth, hands-free telephone radio, smartphone holder, USB charger and a 12V power outlet. Adding to the standard features is KOBELCO's KOMEXS telematic system, K-LOAD weighing system and a four-year, or 4,000 hour limited full machine warranty.
