Smallest Mark 9 excavator delivers plenty of power and versatility

RACINE, Wis.  – Kobelco Construction Machinery America today introduced the SK210 full-size, high-performance excavator to the Kobelco Mark 9 excavator series. These new Tier 4 models include the SK260, SK295, SK350 and SK485 excavators. The versatile SK210 Mark 9 delivers a 10-percent improvement in both fuel efficiency and productivity, with more power and faster engine response.

Featuring an upgrade to Kobelco’s legendary intelligent hydraulics and a new Economy power mode, the SK210 Mark 9 is equipped with the industry’s first selective catalytic reduction (SCR) emission solution for excavators. A new ROPS/FOPS certified cab provides a larger, more comfortable work environment, and a low engine cover and standard rear-view camera improve operator visibility and productivity.

For improved system efficiency and reduced component wear, the Kobelco SK210 Mark 9 also features a fully automatic engine and hydraulic warm-up system. This warms the hydraulic circuit to an optimum 126° F (52° C).

“As with all the Mark 9 models, the SK210 continues Kobelco’s tradition as a technology leader,” said Reece Norwood, Kobelco platform manager. “This new machine delivers the precise control and feel expert operators prefer. The SK210 Mark 9 can dig the trench, crane the pipe and finish with even better precision. Plus, our new SCR solution will deliver more useable engine power and fuel efficiency.” 

The Kobelco SK210 Mark 9 features an operating weight of 47,840 lbs (21,700 kg) and a dig depth of 21 ft 3 in (6.47 m). The new model delivers 160 horsepower (119.3 kW).

Improved controllability and productivity

The upgraded Intelligent Total Control System™ (ITCS) incorporates the culmination of three generations of continuous improvement in hydraulic controls, based on extensive customer input and product testing.

“The SK210 Mark 9 excavator maximizes the unique capabilities of its Tier 4 Interim certified FPT engine and optimized hydraulics with the upgraded ITCS,” Norwood said. “ITCS recognizes the operator’s moves and assists by providing power where and when it is needed. It also provides hydraulic sensitivity for fine grading and leveling.”

Integrated swing priority, a Kobelco first, provides seamless and smooth transition of additional pump power to the swing function. Automatic hydraulic regeneration feeds the cylinder demanding oil first, with oil that is being pushed out of another cylinder. This requires much less energy than having to re-pump the oil again, and also allows the next action to happen with faster response. The independent travel feature, activated with a switch, dedicates a pump to travel motors for better movement while performing other functions, such as when handling pipe while moving to the trench.

“The Kobelco Mark 9 excavators set the industry standard in terms of controllability, especially in multifunction applications,” Norwood said. “Operators will appreciate the impressive control and smoothness of the SK210 Mark 9, and the added confidence will make them even more productive. The ease of operation makes a good operator a great operator, and allows a novice excavator operator to be a good, productive operator.”

Kobelco Mark 9 upgrades to the main valve and intelligent hydraulics, as well as new joysticks with proportional controls for the auxiliary hydraulics, contribute to the controllability upgrades of this new excavator. 

The Power Boost™ feature on the SK210 Mark 9 delivers 10-percent more bucket breakout force on command, without time limit, while the Heavy Lift delivers 10-percent more lifting and swing capability on command, without time limit.
