Kobelco Construction Machinery America introduced three new full-size, high performance excavators on March 24 during CONEXPO-CON/AGG 2011.
The new Kobelco Mark 9 excavators – the SK260-9, SK295-9 and SK350-9 – feature an upgrade to Kobelco’s intelligent hydraulics as well as introduce a new economy power mode.
The machines launch what the manufacturer claims is the industry’s first selective catalytic reduction (SCR) emission solution for excavators. The excavators also feature a new ROPS/FOPS cab for a more comfortable work environment.
“With the new Mark 9 models, Kobelco continues its tradition as a technology leader,” said Reece Norwood, Kobelco platform manager. “Long known for delivering the precise control and feel that expert operators prefer, these new Kobelco excavators can dig the trench, crane the pipe and finish with even better precision. Plus, our new SCR solution will deliver more engine power and fuel efficiency.”
The operating weights for the Kobelco Mark 9 excavators range from 59,524 to 80,909 pounds, and dig depths range from 23 feet to 24 feet 10 inches. These three new models deliver 181, 197 and 269 horsepower, respectively.
Upgraded Intelligent Total Control System
The upgraded Intelligent Total Control System (ITCS) on all three excavators incorporates the culmination of three generations of continuous improvement in hydraulic con
trols, based on extensive customer input and product testing.
“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, and the added confidence will make them even more productive. The ease of operation allows even a novice excavator operator to be productive on the job.”
By choosing SCR technology for meeting Tier 4 Interim emissions regulations, Kobelco provides leadership in engine performance, productivity and fuel efficiency.
The new Mark 9 excavator engines also provide a new economy work mode that takes Kobelco’s patented ITCS to a new level, maintaining productivity while increasing fuel efficiency by an average of 10 percent over previous models. A new control monitor provides key operating data, including a new function which graphs fuel consumption per hour, and a rear camera view.
A wide range of applications
The largest of the new Mark 9 excavators, the SK350-9 is one of the most productive machines in its size class. This machine is engineered for heavy applications, including road and bridge, sewer and underground utilities and mainline pipeline construction.
To meet customers’ needs for a wide variety of applications, the Kobelco Mark 9 excavators are available with several factory-available configurations – including High & Wide, Long Reach and Mass Excavation versions – and a choice of three undercarriage options. Heavy-duty frames, booms, arms and undercarriages are standard on all three Mark 9 excavators.
The SK260-9 Long Reach has a maximum reach of more than 60 feet. The SK295-9 High & Wide has a more stable stance, making it ideal for such applications as craning large pipe, loading out trucks, and scrap and forestry work.
Additional features on the new Kobelco Mark 9 excavators include a rear-view camera to expand the operator’s view to the back of the machine, rear work lamps for improved visibility, swing flashers and step extensions.
Kobelco Mark 9 excavators are also compatible with grade control systems from leading suppliers to meet customer preference and applications.
Kobelco also offers a new tooth system on buckets for increased productivity and uptime. The Kobelco SmartFit bucket tooth system with tips can be quickly switched without hammering pins.
