Model SK55SRX-7 KOBELCO excavator is an 11,817-pound short-radius mini excavator that can dig to 12 feet 9 inches. Powered by a 37-horsepower Yanmar diesel engine, it has a new hydraulic system that shortens the digging-cycle time by up to 7 percent compared to the previous 6E series unit. Performance can be maintained without reducing speed.
Redesigned travel motors increase travel speed by up to 12 percent and hill-climbing speeds by up to 10 percent. Other benefits of the new hydraulic system include smoother operation and improved levelling performance.
The Integrated Flow Pump System enables operators to harness extra output from the third pump, which otherwise powers the swing and dozer circuit. This additional output is directed to the arm and boom for added power when digging, resulting in a fast and smooth raising operation, even with heavy loads.
Maximum digging height with the standard arm is 19 feet 6 inches, and maximum reach at ground level is 20 feet.
The KOBELCO excavator has a compact tail swing that allows for a smaller working footprint. The standard arm is 5 feet 7 inches, with an available long arm at 6 feet 4 inches. Both come with a thumb bracket pre-installed.
A 2-way dozer blade with float is designed so the earth falls forward and not behind the blade when dozing. Inside the cabin, the dozer can be controlled by the ergonomically designed lever, which is easier to grip, and the first and second speed switches have been repositioned to improve maneuverability. A 4-way (power angle) dozer blade with float is also available as an option.
A new color display is now standard and provides easy access to operating history, maintenance cycle, and fuel and water temperature gauges. It can also be used to adjust the hydraulic oil flow to the attachments. When in Energy Conservation mode, the SK55SRX-7 adapts S-mode to enable 26 percent less fuel consumption when compared with H-mode, and an auto-deceleration switch is installed as standard.
The high-strength cab/canopy meets ROPS, TOPS, and OPG Level 1 (top guard) standards, and new LED work lights are mounted on the boom, top front, and left side of the cab from the factory. The wiper mount has been moved to the upper right of the cab support and the skylight opening has been enlarged to improve operator visibility.
