The largest of the Kobelco Mark 9 excavator series, the new Tier 4 SK485 Mark 9 delivers up to 15% improvement in fuel efficiency. A new ROPS/FOPS cab provides a larger, more comfortable work environment. A low engine cover and standard rear-view camera improve visibility and operator productivity. The 345hp model features an operating weight of 111,774 lbs. and a dig depth of 25 ft., 7.5 in. 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. 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 that 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.
